Description

One aspect of the present invention relates to a display device. One aspect of the present invention relates to a display device that can be mounted on a vehicle. One aspect of the present invention relates to a driving support system.

One aspect of the present invention is not limited to the above technical fields. The technical fields of one aspect of the present invention disclosed in the present specification include semiconductor devices, display devices, light emitting devices, lighting devices, power storage devices, and the like.
Storage devices, their driving methods, or their manufacturing methods can be given as an example.

In recent years, there has been a demand for larger display devices. For example, many television devices having a display panel with a diagonal size of 40 inches or more are widely used in ordinary households, and it is expected that the size will be further increased in the future.

In addition, display devices are expected to be applied to various uses, and their forms are being diversified.

Typical display devices include liquid crystal display devices and organic EL (Electro Lumin).
Secence) element and light emitting diode (LED: Light Emitting Di)
Examples thereof include a light emitting device provided with a light emitting element such as ode), an electronic paper that displays by an electrophoresis method, and the like.

For example, the basic configuration of an organic EL device is such that a layer containing a luminescent organic compound is sandwiched between a pair of electrodes. By applying a voltage to this device, light emission can be obtained from a luminescent organic compound. Since the display device to which such an organic EL element is applied does not require a backlight, which is required for a liquid crystal display device or the like, a thin, lightweight, high-contrast, and low-power consumption display device can be realized.

Further, Patent Document 1 discloses a flexible active matrix type light emitting device provided with a transistor as a switching element and an organic EL element on a film substrate.

In recent years, the expansion of large-scale commercial facilities in the suburbs has progressed, and an increasing number of people are shopping for daily necessities and foodstuffs at the large-scale commercial facilities rather than at stores within walking distance from residential areas. Such large commercial facilities are often located away from residential areas and the suburbs of metropolitan areas and are equipped with large parking lots. Therefore, it is often convenient to use a private car as a means of transportation. recent years,
This is one of the reasons why the number of private cars owned is on the rise.

However, there is a problem that the incidence of traffic accidents increases as the traffic volume increases. In addition, there is a high probability that a traffic accident will occur in a group of people who drive infrequently, such as driving only on holidays, rather than driving on a daily basis for commuting to work or school. Moreover, as we enter a super-aging society in the near future, how to reduce the incidence of traffic accidents has become an issue. Therefore, the development of a driving support system is being promoted, such as providing the driver with information on the surroundings or detecting a danger and warning the driver.

A navigation system is known as one of the driving support systems. The navigation system is equipped with a display device such as a liquid crystal display device, and supports the driver's driving by displaying a map, location information, a route to a destination, traffic information, etc. on the display unit of the display device.

(Embodiment 1)
In the present embodiment, a configuration example and a manufacturing method example of a light emitting panel applicable to the display panel included in the display device of one aspect of the present invention will be described.

The display panel of one aspect of the present invention has a configuration in which a display element provided between a pair of substrates is sealed by a sealing layer. Further, the protective film is formed so as to cover the exposed portion of the sealing layer.

Further, the protective film can be provided so as to cover the exposed portion of the display panel. For example, it can be provided so as to cover the exposed side surfaces such as the surface and side surfaces of a pair of substrates, a sealing layer, an insulating layer, and the like.

The protective film is provided so as to cover at least the exposed side portion of the sealing layer and a part of the substrate around it. The protective film is preferably formed by using a film forming method having good step coverage (step coverage). One such technique is atomic layer deposition (ALD: Atomic La).
There is a yer Deposition) method.

For the protective film, a material that does not easily allow impurities such as water to permeate can be used. Therefore,
It is possible to effectively prevent impurities such as water from diffusing from the outside to the inside.

For example, oxides, nitrides, fluorides, sulfides, ternary compounds, metals or polymers can be used.

For example, aluminum oxide, hafnium oxide, hafnium silicate, lanthanum oxide,
Silicon oxide, strontium titanate, tantalum oxide, titanium oxide, zinc oxide, niobium oxide, zirconium oxide, tin oxide, yttrium oxide, cerium oxide, scandium oxide,
Materials containing erbium oxide, vanadium oxide, indium oxide and the like can be used.

For example, aluminum nitride, hafnium nitride, silicon nitride, tantalum nitride, titanium nitride,
Materials containing niobium nitride, molybdenum nitride, zirconium nitride, gallium nitride and the like can be used.

For example, nitrides containing titanium and aluminum, oxides containing titanium and aluminum, oxides containing aluminum and zinc, sulfides containing manganese and zinc, sulfides containing cerium and strontium, oxides containing erbium and aluminum, Materials containing oxides containing iturium and zirconium can be used.

For example, it is preferable to use a material that can be formed by the ALD method for the protective film. By using the ALD method, it is possible to form a protective film having a dense, reduced defects such as cracks and pinholes, or a uniform thickness. In addition, damage to the processed member when forming the protective film can be reduced.

For example, by forming the protective film by using the ALD method, it is possible to form a protective film having a complicated uneven shape and a uniform and few defects on the upper surface, the side surface and the back surface of the touch panel.

For example, when an organic EL element is used as a display element, water or the like diffuses into the organic EL element, resulting in deterioration. Further, in the case of a liquid crystal element, the resistance of the liquid crystal changes. Further, in a transistor, particularly a transistor in which an oxide semiconductor is applied to a semiconductor layer, the characteristics may change due to the diffusion of water or the like in the semiconductor.

By applying such a protective film to the display panel, it is possible to prevent impurities such as moisture from diffusing from the outside into the display panel. Therefore, it is possible to prevent the impurities from diffusing into display elements (organic EL elements, liquid crystal elements, etc.) constituting the display panel, transistors, wiring, electrodes, and the like. As a result, a display panel with extremely high reliability can be realized.

More specifically, for example, the following configuration can be used.

[Specific example 1]
A plan view of the light emitting panel is shown in FIG. 1 (A), and an example of a cross-sectional view between the alternate long and short dash lines A1 to A2 in FIG. 1 (A) is shown in FIG. 1 (C). The light emitting panel shown in Specific Example 1 is a top emission type light emitting panel using a color filter method. In the present embodiment, the light emitting panel has, for example, a configuration in which one color is expressed by three sub-pixels of R (red), G (green), and B (blue).
R (red), G (green), B (blue), W (white), or R (red), G (green), B (blue), Y (
A configuration in which one color is expressed by sub-pixels of four colors (yellow) can be applied. The color element is not particularly limited, and a color other than RGBW may be used, and may be composed of, for example, yellow, cyan, magenta, or the like.

The light emitting panel shown in FIG. 1 (A) includes a light emitting unit 804, a drive circuit unit 806, and an FPC (Flex).
It has an ible Printed Circuit) 808. The light emitting elements and transistors included in the light emitting unit 804 and the drive circuit unit 806 are the substrate 801 and the substrate 803, and the sealing layer 8.
It is sealed by 23.

The light emitting panel shown in FIG. 1C includes a substrate 801, an adhesive layer 811 and an insulating layer 813, a plurality of transistors, a conductive layer 857, an insulating layer 815, an insulating layer 817, a plurality of light emitting elements, and an insulating layer 82.
1. Sealing layer 823, overcoat 849, colored layer 845, light-shielding layer 847, insulating layer 843
, Adhesive layer 841, substrate 803, and protective film 800. The sealing layer 823, the overcoat 849, the insulating layer 843, the adhesive layer 841, the substrate 803, and the protective film 800 transmit visible light.

The light emitting unit 804 has a transistor 820 and a light emitting element 830 on the substrate 801 via an adhesive layer 811 and an insulating layer 813. The light emitting element 830 is a lower electrode 83 on the insulating layer 817.
1. It has an EL layer 833 on the lower electrode 831 and an upper electrode 835 on the EL layer 833. The lower electrode 831 is electrically connected to the source electrode or drain electrode of the transistor 820. The end of the lower electrode 831 is covered with an insulating layer 821. The lower electrode 831 preferably reflects visible light. The upper electrode 835 transmits visible light.

Further, the light emitting unit 804 has a colored layer 845 that overlaps with the light emitting element 830 and a light shielding layer 847 that overlaps with the insulating layer 821. The colored layer 845 and the light-shielding layer 847 are covered with an overcoat 849. The space between the light emitting element 830 and the overcoat 849 is filled with a sealing layer 823.

The insulating layer 815 has the effect of suppressing the diffusion of impurities into the semiconductors constituting the transistor. Further, for the insulating layer 817, it is preferable to select an insulating layer having a flattening function in order to reduce surface irregularities caused by transistors.

The drive circuit unit 806 has a plurality of transistors on the substrate 801 via the adhesive layer 811 and the insulating layer 813. In FIG. 1C, one of the transistors included in the drive circuit unit 806 is shown.
Shows one transistor.

The insulating layer 813 and the substrate 801 are bonded by an adhesive layer 811. Further, the insulating layer 843 and the substrate 803 are bonded to each other by the adhesive layer 841. It is preferable to use a film having low water permeability for the insulating layer 813 and the insulating layer 843 because impurities such as water can be suppressed from entering the light emitting element 830 and the transistor 820, and the reliability of the light emitting panel is improved.

The conductive layer 857 is electrically connected to an external input terminal that transmits an external signal (video signal, clock signal, start signal, reset signal, etc.) or potential to the drive circuit unit 806.
Here, an example in which the FPC 808 is provided as the external input terminal is shown. In order to prevent an increase in the number of steps, it is preferable that the conductive layer 857 is made of the same material and the same steps as the electrodes and wiring used for the light emitting portion and the drive circuit portion. Here, an example in which the conductive layer 857 is made of the same material as the electrodes constituting the transistor 820 and in the same process is shown.

In the light emitting panel shown in FIG. 1C, the connector 825 is located on the substrate 803. Connection body 8
The 25 is connected to the conductive layer 857 through the openings provided in the substrate 803, the adhesive layer 841, the insulating layer 843, the sealing layer 823, the insulating layer 817, and the insulating layer 815. Also, the connector 82
5 is connected to FPC808. The FPC 808 and the conductive layer 857 are electrically connected via the connecting body 825. When the conductive layer 857 and the substrate 803 overlap, the substrate 803 is opened (or a substrate having an opening is used) to open the conductive layer 857, the connector 825, and the FP.
The C808 can be electrically connected.

In Specific Example 1, an insulating layer 813, a transistor 820, and a light emitting element 830 are manufactured on a highly heat-resistant manufacturing substrate, the manufacturing substrate is peeled off, and the insulating layer 8 is placed on the substrate 801 using the adhesive layer 811.
A light emitting panel that can be manufactured by transposing 13, a transistor 820, and a light emitting element 830 is shown. Further, in Specific Example 1, the insulating layer 843 and the colored layer 845 are placed on the manufactured substrate having high heat resistance.
A light emitting panel that can be produced by producing the light-shielding layer 847, peeling off the manufacturing substrate, and transposing the insulating layer 843, the colored layer 845, and the light-shielding layer 847 on the substrate 803 using the adhesive layer 841 is shown.

When a material having low heat resistance (resin or the like) is used for the substrate, it is difficult to apply a high temperature to the substrate in the manufacturing process, so that the conditions for forming a transistor or an insulating layer on the substrate are limited. When a material having high water permeability (resin or the like) is used for the substrate, it is preferable to apply a high temperature to form a film having low water permeability. In the manufacturing method of this embodiment, a transistor or the like can be manufactured on a manufacturing substrate having high heat resistance, so that a highly reliable transistor or a film having sufficiently low water permeability can be formed by applying a high temperature. Then, by transposing them onto the substrate 801 or the substrate 803, a highly reliable light emitting panel can be produced. Thus, in one aspect of the invention,
A light emitting panel that is lightweight or thin and has high reliability can be realized. Details of the manufacturing method will be described later.

In FIG. 1C, the protective film 800 is provided so as to cover the exposed portion of the light emitting panel. Specifically, the substrate 803, the adhesive layer 841, the insulating layer 843, the sealing layer 823, and the insulating layer 8
17. The insulating layer 815, the insulating layer 813, the adhesive layer 811 and the substrate 801 are provided so as to cover a part or all of the exposed surfaces.

Further, as shown in FIG. 1C, it is preferable that an opening is provided in a part of the protective film 800 so that a part of the upper surface of the conductive layer 857 electrically connected to the FPC 808 is exposed. By doing so, it is possible to facilitate the electrical connection between the FPC 808 and the conductive layer 857.

That is, the area other than the connection portion (terminal portion) to which the FPC808 or the like is electrically connected is covered.
A configuration in which the protective film 800 is provided is preferable because the diffusion of impurities from the outside can be effectively suppressed.

When forming a portion to which the protective film 800 is not provided, it may be formed by physically peeling off a part after forming the protective film 800 on the entire surface, or masking before forming the protective film 800. May be formed to form a portion that is not formed into a film.

Further, as shown in FIG. 1C, it is preferable that the protective film 800 is also provided on the inner wall of the opening for providing the connecting body 825 because the diffusion of impurities can be more effectively suppressed.

The protective film 800 may not be provided on the inner wall of the opening. FIG. 2A shows an example in which the protective film 800 is formed before the opening, which will be described later, is formed. Further, FIG. 2B shows an example in which the protective film 800 is not formed in the vicinity of the opening. Further, in FIG. 3, F
An example is shown in the case where the protective film 800 is formed after the PC808 is attached.

For the protective film 800, a material that does not easily permeate impurities such as water can be preferably used. In particular, aluminum oxide, hafnium oxide, silicon nitride and the like are preferable because they have extremely low moisture permeability and thus secure barrier properties even if they are formed thin.

Further, in the light emitting panel shown in FIG. 1D, the sizes of the substrate 801 and the substrate 803 are different. The connector 825 is located on the insulating layer 843 and does not overlap the substrate 803. The connecting body 825 is connected to the conductive layer 857 through the openings provided in the insulating layer 843, the sealing layer 823, the insulating layer 817, and the insulating layer 815. Since it is not necessary to provide an opening in the substrate 803, the material of the substrate 803 is not limited.

[Specific example 5]
FIG. 4 (E) shows an example of a light emitting panel different from the specific examples 1 to 4. Here, only the points different from the above specific example will be described in detail, and the points common to the above specific example will be omitted.

The light emitting panel shown in FIG. 4 (E) includes a substrate 801, an adhesive layer 811, an insulating layer 813, and a conductive layer 8.
14, Conductive layer 857a, Conductive layer 857b, Light emitting element 830, Insulating layer 821, Sealing layer 823
, And a substrate 803.

The conductive layer 857a and the conductive layer 857b have a function as an external connection electrode of the light emitting panel and can be electrically connected to an FPC or the like.

The light emitting element 830 has a lower electrode 831, an EL layer 833, and an upper electrode 835. The end of the lower electrode 831 is covered with an insulating layer 821. The light emitting element 830 is a bottom emission type, a top emission type, or a dual emission type.

For example, a light extraction structure can be formed by adhering the lens or film on a resin substrate using the substrate or an adhesive having a refractive index similar to that of the lens or film.

Although it is not always necessary to provide the conductive layer 814, it is preferable to provide the conductive layer 814 because the voltage drop due to the resistance of the lower electrode 831 can be suppressed. Further, for the same purpose, a conductive layer electrically connected to the upper electrode 835 may be provided on the insulating layer 821, the EL layer 833, the upper electrode 835, or the like.

The conductive layer 814 is a single layer or laminated using a material selected from copper, titanium, tantalum, tungsten, molybdenum, chromium, neodymium, scandium, nickel, aluminum, or an alloy material containing these as the main components. Can be formed. The film thickness of the conductive layer 814 can be, for example, 0.1 μm or more and 3 μm or less, preferably 0.1 μm or more and 0.

The manufactured substrate is peeled off, and the insulating layer 813 and the light emitting element 83 are placed on the substrate 801 using the adhesive layer 811.
A light emitting panel that can be manufactured by transposing 0 mag is shown. On a highly heat-resistant fabrication substrate
A highly reliable light emitting panel can be produced by applying a high temperature to form a film having sufficiently low water permeability (for example, an insulating layer 813 or the like) and transposing it onto the substrate 801. Thereby, in one aspect of the present invention, a light emitting panel that is lightweight or thin and has high reliability can be realized.

The protective film 800 is provided so as to cover the exposed portion of the light emitting panel. Specifically, it is provided so as to cover a part or all of the exposed surfaces such as the substrate 803, the sealing layer 823, the insulating layer 813, the adhesive layer 811, and the substrate 801. Further, the protective film 800 has an opening that overlaps a part of the surfaces of the conductive layer 857a and the conductive layer 857b.

Although an example in which a light emitting element is used as the display element is shown here, one aspect of the present invention is not limited to this.

For example, MEMS (Micro Electro Mechanical System)

As display elements using MS, a shutter type MEMS display element and an optical interference type ME
Examples include MS display elements. Carbon nanotubes may be used as the electron emitting device. Moreover, you may use electronic paper. As the electronic paper, an element to which a microcapsule method, an electrophoresis method, an electrowetting method, an electronic powder fluid (registered trademark) method or the like is applied can be used.

[Example of material]
Next, materials and the like that can be used for the light emitting panel will be described. The configuration described above in this specification may be omitted.

Materials such as glass, quartz, organic resin, metal, and alloy can be used for the substrate. For the substrate on the side that extracts light from the light emitting element, a material having translucency to the light is used.

In particular, it is preferable to use a flexible substrate. For example, an organic resin or glass, metal, or alloy having a thickness sufficient to have flexibility can be used.

Since organic resin has a lower specific gravity than glass, if organic resin is used as a flexible substrate,
The light emitting panel can be made lighter than the case of using glass, which is preferable.

It is preferable to use a material having high toughness for the substrate. As a result, it is possible to realize a light emitting panel having excellent impact resistance and being hard to be damaged. For example, by using an organic resin substrate or a thin metal substrate or alloy substrate, it is possible to realize a light emitting panel that is lighter in weight and less likely to be damaged as compared with the case of using a glass substrate.

Since the metal material and the alloy material have high thermal conductivity and can easily conduct heat to the entire substrate, it is possible to suppress a local temperature rise of the light emitting panel, which is preferable. The thickness of the substrate using the metal material or alloy material is preferably 10 μm or more and 200 μm or less, and more preferably 20 μm or more and 50 μm or less.

The material constituting the metal substrate or alloy substrate is not particularly limited, and for example, a metal such as aluminum, copper, iron, titanium, or nickel, or an alloy containing one or more metals selected from these metals is used. Can be done. As the alloy, for example, an aluminum alloy, stainless steel, or the like can be preferably used.

Further, when a material having a high thermal emissivity is used for the substrate, it is possible to suppress an increase in the surface temperature of the light emitting panel, and it is possible to suppress destruction of the light emitting panel and deterioration of reliability. For example, the substrate may have a laminated structure of a metal substrate and a layer having a high thermal emissivity (for example, a metal oxide or a ceramic material can be used).

Examples of the flexible and translucent material include polyethylene terephthalate (PE).
Polyester resin such as T), polyethylene naphthalate (PEN), polyacrylonitrile resin, polyimide resin, polymethylmethacrylate resin, polycarbonate (PC) resin, polyethersulfone (PES) resin, polyamide resin, cycloolefin resin, polystyrene resin, Examples thereof include polyamideimide resin, polyvinyl chloride resin, and polytetrafluoroethylene (PTFE). In particular, it is preferable to use a material having a low coefficient of thermal expansion.
For example, polyamide-imide resin, polyimide resin, PET and the like can be preferably used. Further, a substrate in which a fiber body is impregnated with a resin (also referred to as a prepreg) or a substrate in which an inorganic filler is mixed with an organic resin to reduce the coefficient of thermal expansion can also be used.

As the flexible substrate, the layer using the above material is a hard coat layer (for example, a silicon nitride layer) that protects the surface of the device from scratches or the like, or a layer of a material that can disperse the pressure (for example, an aramid resin). It may be configured by being laminated with a layer or the like).

The flexible substrate can also be used by laminating a plurality of layers. In particular, when the structure has a glass layer, the barrier property against water and oxygen can be improved, and a highly reliable light emitting panel can be obtained.

For example, a flexible substrate in which a glass layer, an adhesive layer, and an organic resin layer are laminated from the side close to the light emitting element can be used. The thickness of the glass layer is 20 μm or more and 200 μm or less, preferably 25 μm or more and 100 μm or less. A glass layer having such a thickness can simultaneously realize high barrier property against water and oxygen and flexibility. The thickness of the organic resin layer is 1
It is 0 μm or more and 200 μm or less, preferably 20 μm or more and 50 μm or less. By providing such an organic resin layer on the outer side of the glass layer, cracks and cracks in the glass layer can be suppressed and the mechanical strength can be improved. By applying such a composite material of a glass material and an organic resin to a substrate, an extremely reliable and flexible light emitting panel can be obtained.

As the adhesive layer and the sealing layer, various curable adhesives such as a photocurable adhesive such as an ultraviolet curable type, a reaction curable adhesive, a thermosetting adhesive, and an anaerobic adhesive can be used. These adhesives include epoxy resin, acrylic resin, silicone resin, phenol resin, polyimide resin, etc.
Examples thereof include imide resin, PVC (polyvinyl chloride) resin, PVB (polyvinyl butyral) resin, EVA (ethylene vinyl acetate) resin and the like. In particular, a material having low moisture permeability such as epoxy resin is preferable. Further, a two-component mixed type resin may be used. Moreover, you may use an adhesive sheet or the like.

Further, the resin may contain a desiccant. For example, a substance that adsorbs water by chemisorption, such as an oxide of an alkaline earth metal (calcium oxide, barium oxide, etc.), can be used. Alternatively, a substance that adsorbs water by physical adsorption, such as zeolite or silica gel, may be used. When a desiccant is contained, impurities such as moisture can be suppressed from entering the functional element, and the reliability of the light emitting panel is improved, which is preferable.

Further, by mixing the resin with a filler having a high refractive index or a light scattering member, the light extraction efficiency from the light emitting element can be improved. For example, titanium oxide, barium oxide,
Zeolites, zirconium and the like can be used.

The structure of the transistor included in the light emitting panel is not particularly limited. For example, it may be a staggered transistor or an inverted staggered transistor. Further, either a top gate type or bottom gate type transistor structure may be used. The semiconductor material used for the transistor is not particularly limited, and examples thereof include silicon, germanium, silicon carbide, and gallium nitride. Alternatively, an oxide semiconductor containing at least one of indium, gallium, and zinc, such as an In—Ga—Zn-based metal oxide, may be used.

The crystallinity of the semiconductor material used for the transistor is also not particularly limited, and the amorphous semiconductor,
Any of the semiconductors having crystallinity (microcrystalline semiconductors, polycrystalline semiconductors, single crystal semiconductors, or semiconductors having a partially crystalline region) may be used. It is preferable to use a semiconductor having crystallinity because deterioration of transistor characteristics can be suppressed.

Here, it is preferable to apply an oxide semiconductor to a semiconductor device such as a pixel, a drive circuit, or a transistor used for a touch sensor or the like described later. In particular, it is preferable to apply an oxide semiconductor having a bandgap larger than that of silicon. It is preferable to use a semiconductor material having a wider bandgap and a smaller carrier density than silicon because the current in the off state of the transistor can be reduced.

For example, it is preferable that the oxide semiconductor contains at least at least indium (In) or zinc (Zn). More preferably, it is an In-M-Zn-based oxide (M is A).
Contains oxides represented by (metals such as l, Ti, Ga, Ge, Y, Zr, Sn, La, Ce or Hf).

In particular, the semiconductor layer has a plurality of crystal portions, and the c-axis of the crystal portion is oriented perpendicular to the surface to be formed of the semiconductor layer or the upper surface of the semiconductor layer, and grain boundaries are formed between adjacent crystal portions. It is preferable to use an oxide semiconductor film that cannot be confirmed.

Since such an oxide semiconductor does not have grain boundaries, it is possible to prevent cracks from being generated in the oxide semiconductor film due to stress when the display panel is curved. Therefore,
Such an oxide semiconductor can be suitably used for a display panel or the like which has flexibility and is used by being curved.

By using a material having such crystallinity as the semiconductor layer, fluctuations in electrical characteristics are suppressed, and a highly reliable transistor can be realized.

Transistors using oxide semiconductors with a bandgap larger than that of silicon are also available.
Due to its low off-current, it is possible to retain the charge accumulated in the capacitance connected in series with the transistor for a long period of time. By applying such a transistor to a pixel,
It is also possible to stop the drive circuit while maintaining the gradation of the image displayed in each display area.
As a result, it is possible to realize an electronic device with extremely reduced power consumption.

It is preferable to provide a base film for stabilizing the characteristics of the transistor. As the base film, an inorganic insulating film such as a silicon oxide film, a silicon nitride film, a silicon oxide film, or a silicon nitride film can be used, and can be produced as a single layer or laminated. The base film is a sputtering method or a CVD (Chemical Vapor Deposition) method (plasma CVD).
Method, thermal CVD method, MOCVD (Metal Organic CVD) method, etc.), ALD
It can be formed by using an (Atomic Layer Deposition) method, a coating method, a printing method, or the like. The base film may not be provided if it is not necessary. In each of the above configuration examples, the insulating layer 813 can also serve as the base film of the transistor.

As the light emitting element, an element capable of self-luminous light can be used, and an element whose brightness is controlled by a current or a voltage is included in the category. For example, a light emitting diode (LED), an organic EL element, an inorganic EL element, or the like can be used.

The light emitting element may be any of a top emission type, a bottom emission type, and a dual emission type. A conductive film that transmits visible light is used for the electrode on the side that extracts light. Further, it is preferable to use a conductive film that reflects visible light for the electrode on the side that does not take out light.

The conductive film that transmits visible light is, for example, indium oxide, indium tin oxide (ITO:
It can be formed by using Indium Tin Oxide), indium zinc oxide, zinc oxide, zinc oxide added with gallium, or the like. Further, metal materials such as gold, silver, platinum, magnesium, nickel, tungsten, chromium, molybdenum, iron, cobalt, copper, palladium, or titanium, alloys containing these metal materials, or nitrides of these metal materials (for example, Titanium nitride) or the like can also be used by forming it thin enough to have translucency. Further, the laminated film of the above material can be used as the conductive layer. For example, it is preferable to use a laminated film of an alloy of silver and magnesium and ITO because the conductivity can be enhanced.
Moreover, graphene or the like may be used.

As the conductive film that reflects visible light, for example, a metal material such as aluminum, gold, platinum, silver, nickel, tungsten, chromium, molybdenum, iron, cobalt, copper, or palladium, or an alloy containing these metal materials should be used. Can be done. Further, lanthanum, neodymium, germanium or the like may be added to the above metal materials or alloys. Also, aluminum-containing alloys (aluminum alloys) such as aluminum-titanium alloys, aluminum-nickel alloys, aluminum-neodim alloys, silver-copper alloys, silver-palladium-copper alloys, etc.
It can be formed by using an alloy containing silver such as an alloy of silver and magnesium. Alloys containing silver and copper are preferred because of their high heat resistance. Further, by laminating a metal film or a metal oxide film in contact with the aluminum alloy film, oxidation of the aluminum alloy film can be suppressed. Examples of the material of the metal film and the metal oxide film include titanium and titanium oxide. Further, the conductive film that transmits visible light and the film made of a metal material may be laminated. For example, silver and ITO
, A laminated film of silver and magnesium alloy and ITO can be used.

The electrodes may be formed by a vapor deposition method or a sputtering method, respectively. In addition, it can be formed by using a ejection method such as an inkjet method, a printing method such as a screen printing method, or a plating method.

When a voltage higher than the threshold voltage of the light emitting element is applied between the lower electrode 831 and the upper electrode 835, holes are injected into the EL layer 833 from the anode side, and electrons are injected from the cathode side. The injected electrons and holes are recombined in the EL layer 833, and the luminescent substance contained in the EL layer 833 emits light.

The layers constituting the EL layer 833 can be formed by a vapor deposition method (including a vacuum vapor deposition method), a transfer method, a printing method, an inkjet method, a coating method, or the like, respectively.

When a white light emitting element is applied as the light emitting element 830, it is preferable that the EL layer 833 contains two or more kinds of light emitting substances. For example, white light emission can be obtained by selecting a light emitting substance so that the light emission of each of two or more light emitting substances has a complementary color relationship. For example, a luminescent substance that emits light such as R (red), G (green), B (blue), Y (yellow), O (orange), or spectral components of two or more colors of R, G, and B, respectively. It is preferable that two or more of the luminescent substances exhibiting luminescence containing the above are contained. Further, it is preferable to apply a light emitting element having two or more peaks in the spectrum of light emission from the light emitting element 830 within the wavelength range of the visible light region (for example, 350 nm to 750 nm). Further, the emission spectrum of the material having a peak in the yellow wavelength region is preferably a material having a spectral component also in the green and red wavelength regions.

More preferably, the EL layer 833 has a configuration in which a light emitting layer containing a light emitting material that emits one color and a light emitting layer containing a light emitting material that emits another color are laminated. For example, E
The plurality of light emitting layers in the L layer 833 may be laminated so as to be in contact with each other, or may be laminated via a region that does not contain any light emitting material. For example, a region is provided between the fluorescent light emitting layer and the phosphorescent light emitting layer, which contains the same material as the fluorescent light emitting layer or the phosphorescent light emitting layer (for example, a host material or an assist material) and does not contain any light emitting material. May be good. This facilitates the fabrication of the light emitting element and reduces the drive voltage.

Further, the light emitting element 830 may be a single element having one EL layer, or may be a tandem element in which a plurality of EL layers are laminated via a charge generation layer.

The light emitting element is preferably provided between a pair of low water-permeable insulating films.

A color filter or the like can be used. Each colored layer is formed at a desired position by a printing method, an inkjet method, an etching method using a photolithography method, or the like using various materials.

The light-shielding layer is provided between adjacent colored layers. The light-shielding layer blocks light from adjacent light-emitting elements and suppresses color mixing between adjacent light-emitting elements. Here, by providing the end portion of the colored layer so as to overlap the light-shielding layer, light leakage can be suppressed. As a light-shielding layer
A material that blocks light emission from the light emitting element can be used. For example, a black matrix may be formed by using a metal material or a resin material containing a pigment or a dye. It is preferable to provide the light-shielding layer in a region other than the light-emitting portion such as the drive circuit portion because it is possible to suppress unintended light leakage due to waveguide light or the like.

Further, an overcoat may be provided to cover the colored layer and the light-shielding layer. By providing the overcoat, it is possible to prevent the impurities contained in the colored layer from diffusing into the light emitting element.

Next, a plurality of transistors, a conductive layer 857, an insulating layer 815, an insulating layer 817, a plurality of light emitting elements, and an insulating layer 821 are formed on the insulating layer 813. The insulating layer 821, the insulating layer 817, and the insulating layer 815 are opened so that the conductive layer 857 is exposed (FIG. 5 (A)).
..

Further, the release layer 207 is formed on the production substrate 205, and the insulating layer 843 is formed on the release layer 207. Next, a light-shielding layer 847, a colored layer 845, and an overcoat 84 are placed on the insulating layer 843.
9 is formed (FIG. 5 (B)).

As the production substrate 201 and the production substrate 205, a glass substrate, a quartz substrate, a sapphire substrate, a ceramic substrate, a metal substrate, or the like can be used, respectively.

Further, as the glass substrate, for example, a glass material such as aluminosilicate glass, aluminoborosilicate glass, and bariumborosilicate glass can be used. When the temperature of the subsequent heat treatment is high, it is preferable to use one having a strain point of 730 ° C. or higher. Barium oxide (
By containing a large amount of BaO), more practical heat-resistant glass can be obtained. In addition, crystallized glass or the like can be used.

When a glass substrate is used as the manufacturing substrate, if an insulating film such as a silicon oxide film, a silicon nitride film, a silicon nitride film, or a silicon nitride film is formed between the manufacturing substrate and the release layer, the glass substrate is contaminated. It can be prevented and is preferable.

The peeling layer 203 and the peeling layer 207 include elements selected from tungsten, molybdenum, titanium, tantalum, niobium, nickel, cobalt, zirconium, zinc, ruthenium, rhodium, palladium, osmium, iridium, and silicon, respectively. It is a single layer or a laminated layer composed of an alloy material containing the element or a compound material containing the element. The crystal structure of the layer containing silicon may be amorphous, microcrystal, or polycrystalline.

The release layer can be formed by a sputtering method, a plasma CVD method, a coating method, a printing method, or the like. The coating method includes a spin coating method, a droplet ejection method, and a dispensing method.

When the release layer has a single-layer structure, it is preferable to form a tungsten layer, a molybdenum layer, or a layer containing a mixture of tungsten and molybdenum. Further, a layer containing a tungsten oxide or an oxide nitride, a layer containing a molybdenum oxide or an oxide nitride, or a layer containing an oxide or an oxide nitride of a mixture of tungsten and molybdenum may be formed. In addition, it should be noted.
The mixture of tungsten and molybdenum corresponds to, for example, an alloy of tungsten and molybdenum.

Further, when forming a laminated structure of a layer containing tungsten and a layer containing an oxide of tungsten as a release layer, a layer containing tungsten is formed, and an insulating film formed of an oxide is formed on the upper layer. , It may be utilized that a layer containing a tungsten oxide is formed at the interface between the tungsten layer and the insulating film. Further, the surface of the layer containing tungsten, thermal oxidation treatment, oxygen plasma treatment, nitrous oxide (N 2 _O) plasma treatment, an oxide of tungsten processing or the like in the strong oxidizing solution such as ozone water The containing layer may be formed. Further, the plasma treatment and the heat treatment may be carried out by oxygen, nitrogen, nitrous oxide alone, or in a mixed gas atmosphere of the gas and another gas. By changing the surface state of the release layer by the above plasma treatment or heat treatment, it is possible to control the adhesion between the release layer and the insulating film formed later.

Each insulating layer can be formed by using a sputtering method, a plasma CVD method, a coating method, a printing method, or the like. For example, the film formation temperature is set to 250 ° C. or higher and 400 by the plasma CVD method.
By forming the temperature below ° C, a dense and extremely low water permeability film can be obtained.

After that, a material to be a sealing layer 823 is applied to the surface of the manufacturing substrate 205 provided with the colored layer 845 and the like or the surface of the manufacturing substrate 201 provided with the light emitting element 230 and the like, and the surface is passed through the sealing layer 823. The production substrate 201 and the production substrate 205 are bonded together so that they face each other (FIG. 5 (C).
)).

Then, the manufactured substrate 201 is peeled off, and the exposed insulating layer 813 and the substrate 801 are attached to the adhesive layer 81.
Paste using 1. Further, the manufactured substrate 205 is peeled off, and the exposed insulating layer 843 and the substrate 803 are bonded together using the adhesive layer 841. In FIG. 6A, the substrate 803 is the conductive layer 8
Although the configuration does not overlap with 57, the conductive layer 857 and the substrate 803 may overlap.

In the peeling step, various methods can be appropriately used. For example, when a layer containing a metal oxide film is formed on the side in contact with the layer to be peeled as the peeling layer, the metal oxide film can be fragile by crystallization and the layer to be peeled can be peeled from the manufactured substrate. When an amorphous silicon film containing hydrogen is formed as a peeling layer between the highly heat-resistant fabrication substrate and the layer to be peeled off, the amorphous silicon film is removed by irradiating or etching laser light. , The layer to be peeled off can be peeled off from the manufactured substrate. Further, as a peeling layer, a layer containing a metal oxide film is formed on the side in contact with the layer to be peeled, the metal oxide film is fragile by crystallization, and a part of the peeling layer is made into a solution or NF.
_3. After removal by etching with a fluorine gas such as BrF ₃ , ClF _3, etc., it can be peeled off in a weakened metal oxide film. Furthermore, a film containing nitrogen, oxygen, hydrogen, etc. (for example, an amorphous silicon film containing hydrogen, a hydrogen-containing alloy film, an oxygen-containing alloy film, etc.) is used as the release layer, and the release layer is irradiated with laser light. A method may be used in which nitrogen, oxygen or hydrogen contained in the peeling layer is released as a gas to promote the peeling between the peeled layer and the substrate. Further, a method of mechanically removing the production substrate on which the layer to be peeled is formed or _{etching with a solution or a fluorine gas such as NF 3} , BrF ₃ , ClF ₃ or the like can be used. In this case, it is not necessary to provide the release layer.

Further, the peeling step can be performed more easily by combining a plurality of the peeling methods. In other words, laser light irradiation, etching to the peeling layer with gas or solution, mechanical removal with a sharp knife or knife, etc. are performed to make the peeling layer and the peeling layer easy to peel, and then physical. Peeling can also be performed by force (by a machine or the like).

Further, the liquid to be peeled may be permeated into the interface between the peeled layer and the layer to be peeled to peel the layer to be peeled from the manufactured substrate. Further, when the peeling is performed, the peeling may be performed while sprinkling a liquid such as water.

As another peeling method, when the peeling layer is formed of tungsten, it is preferable to perform peeling while etching the peeling layer with a mixed solution of aqueous ammonia and hydrogen peroxide.

If peeling is possible at the interface between the manufactured substrate and the layer to be peeled, the peeling layer may not be provided. For example, glass is used as a manufacturing substrate, and an organic resin such as polyimide, polyester, polyolefin, polyamide, polycarbonate, or acrylic is formed in contact with the glass, and an insulating film, a transistor, or the like is formed on the organic resin. In this case, by heating the organic resin,
It can be peeled off at the interface between the manufacturing substrate and the organic resin. Alternatively, a metal layer may be provided between the fabrication substrate and the organic resin, the metal layer may be heated by passing an electric current through the metal layer, and peeling may be performed at the interface between the metal layer and the organic resin.

Finally, the conductive layer 857 is exposed by opening the insulating layer 843 and the sealing layer 823 (FIG. 6 (B)). When the substrate 803 is configured to overlap the conductive layer 857, the conductive layer 857
The substrate 803 and the adhesive layer 841 are also opened in order to expose the surface (FIG. 6 (C)). The means for opening is not particularly limited, and for example, a laser ablation method, an etching method, an ion beam sputtering method, or the like may be used. Further, the film on the conductive layer 857 may be cut with a sharp blade or the like, and a part of the film may be peeled off by a physical force.

Although an example in which an opening is provided after forming the insulating layer 843 and the sealing layer 823 is shown here, it is also possible to prevent the insulating layer 843 and the sealing layer 823 from being formed in advance in the portion to be the opening. Alternatively, an adhesive tape may be attached to a portion overlapping the conductive layer 857 in advance, and the tape may be peeled off to form an opening.

After that, the protective film 800 is formed. When the protective film 800 is formed into a film by using the ALD method, it can cover the surface of the light emitting panel to form a dense and uniform protective film 800. An example of an apparatus that can be used for forming the protective film 800 will be described later.

Further, for the protective film 800, a coating method using a liquid material such as a spin coating method or a dip method may be applied in addition to a deposition method such as a sputtering method or a CVD method.

An opening can be provided in the protective film 800 by masking the portion where the protective film 800 is not provided in advance and removing the masking after the protective film 800 is formed. The material used for masking may be a material that can be easily removed later, has heat resistance to the temperature at which the protective film 800 is formed, and is stable to the film forming gas (or liquid). .. For example, it is preferable to use an adhesive tape containing polyimide.

From the above, the light emitting panel can be manufactured.

At this time, by displaying an image of the surroundings of the vehicle on the display panel 51 located in a range that the driver can see, the driver's field of vision can be secured and the driver can drive safely.

Although only the shutter 91 that covers the windshield 61 is specified here, it is preferable to provide the shutter 91 that can cover other windows (glass provided on the rear or side).

For example, in the case of a vehicle for traveling in an area with a high radiation amount, a material that does not transmit radiation can be used for the shutter 91. Further, in the case of a vehicle such as an escort vehicle, a convoy vehicle, or an armored vehicle, a material having high physical strength such as a metal or alloy having a thickness of 5 mm or more can be used for the shutter 91. Such materials often do not transmit visible light.

In a special vehicle to which such a shutter 91 is applied, for example, a small window portion can be provided on the shutter 91 in order to visually recognize the situation around the vehicle body, but in that case, the field of view is narrow.
It may not be possible to grasp the surrounding situation in detail. On the other hand, by applying the display device 50 of one aspect of the present invention, even if the entire window portion such as the windshield 61 is covered by the shutter 91 as shown in FIG. 16B, the display panel 51 It is possible to display the surrounding image captured by the imaging means described later. Further, since it is not necessary to provide a window portion on the shutter 91, it is possible to make a special vehicle with less danger.

Further, the display device of one aspect of the present invention can be applied to any moving body other than the automobile. For example, it is applied to various moving objects such as buses, railroad vehicles such as trains and locomotives, civil engineering or construction vehicles such as crane vehicles and bulldozers, manned robots, aircraft such as airplanes and helicopters, ships, submarines, and spacecraft. It becomes possible to do.

Especially in spacecraft, the size and number of windows are often limited due to the influence of cosmic rays and weight problems. In addition, when the radiant intensity of cosmic rays is high due to the influence of solar flares, it is assumed that the window is covered with a shutter that blocks cosmic rays in order to ensure safety.
Therefore, one aspect of the display device of the present invention, which makes it easy to achieve both a large display area and a small space, can be preferably applied. Further, since the display device of one aspect of the present invention is extremely lightweight and compact, the transportation cost (cost required for launch) can be significantly reduced as compared with the conventional display device.

The above is a description of other application examples.

In the display device of one aspect of the present invention, the flexible display panel can be transformed into a form in which the display panel is located in the user's field of view and a form in which the display panel is housed. Therefore, when the display panel is used, a large amount of information can be provided to the user in a large display area, and when the display panel is not used, the display panel can be stored to save space. Moreover, the display device can be applied without spoiling the aesthetic appearance of the interior of the vehicle body.

sistive Random Access Memory), PRAM (Phase)
change RAM), ReRAM (Resistance RAM), FeRAM
A storage device to which a non-volatile storage element such as (Ferroelectric RAM) is applied, or a storage device to which a volatile storage element such as DRAM (Dynamic Ram) or SRAM (Static RAM) is applied may be used.

The input means 75 is an interface on which the user can input setting information that defines the operation of the control unit 71 in advance. As the input means 75, for example, a direct input means such as a switch, a touch panel, a touch pad, a mouse, a keyboard, a joystick, a trackball, or a data glove can be used. Further, if an indirect (non-contact) input means such as a viewpoint input means, a voice input means, or a gesture input means is used as the input means 75, the driver can input without danger even while driving. Can be done. Further, for example, when the display panel 51 has a function as a touch panel, the display panel 51 is used as an input means 7.
It can also be used as 5.

The control unit 71 has a function of outputting an image to the display panel 51 of the display device 50.

The above is the description of the system configuration example.

[About the form of the display device]
Subsequently, FIG. 18 describes the form of the display device in the driving support system of one aspect of the present invention.
Will be described with reference to. Each figure of FIG. 18 is a schematic view illustrating the relationship between the shape of the display panel 51 of the display device 50 and the driver's field of view. Here, FIG. 18A corresponds to the case where the display panel 51 is in the second form, and FIGS. 18 (B1) and 18 (B2) correspond to the case where the display panel 51 is in the first form. FIG. 18C corresponds to the case where the display panel 51 is in the third form.

[Second form]
FIG. 18A shows a form (second form) in which the display panel 51 of the display device 50 is housed. Further, FIG. 18A shows a surface 82 passing through the viewpoint 81 of the driver 80 and a range (front view 83) in which the driver 80 can see the front of the vehicle body through the windshield 61.

Here, the viewpoint 81 of the driver 80 may change depending on the physique, the sitting position, and the like of the driver 80. For example, as the viewpoint 81, a reference eye point defined by "Japanese Industrial Standard JIS D 0021 Automobile Driver Eye Range" can be used.

The surface 82 can be a horizontal plane passing through the viewpoint 81. Alternatively, the surface 82 may be a surface that passes through the viewpoint 81 and is parallel to the surface that passes through the ground contact points of the three tires. Here, when it is higher than the height of the viewpoint 81, it means that it is located above the surface 82. Viewpoint 8
When the height is 1 or less, it means that it coincides with the surface 82 or is located below the surface 82.

Further, in the present specification and the like, the front view 83 is a plane parallel to the vehicle body center plane (a plane passing through the left and right center lines of the vehicle body and perpendicular to the plane 82) and passing through the viewpoint 81, and the viewpoint 81 and the windshield. It can be a range between the line connecting the upper end of the glass 61 and the line connecting the viewpoint 81 and the lower end of the windshield.

In FIG. 18A, since the display panel 51 of the display device 50 is housed, the front view 8
The display panel 51 is not located at 3. Therefore, the driver 80 can perform normal operation as in the case where the display device 50 is not provided.

[First form]
FIG. 18B1 shows a case where the display panel 51 of the display device 50 intersects the surface 82. That is, the lower end of the display panel 51 is located below the height of the viewpoint 81 of the driver 80. Here, the lower end of the display panel 51 is located below the front view 83. By adopting the display panel 51 in such a form, the driver 80 can see information such as an image displayed on the display panel 51 without changing the line of sight from the state of FIG. 18A.

The state shown in FIG. 18 (B1) can be suitably used when, for example, the vehicle is retracted. At this time, it is preferable that the display panel 51 displays an image of the rear of the vehicle body. The driver 80 can drive while watching the image of the rear of the vehicle body displayed on the display panel 51. Since the display panel 51 is positioned so as to overlap most of the front view 83, the image behind the vehicle body can be displayed in most of the driver 80's view. Therefore, the driver 80 feels more immersive and more realistic than when a display device having a small display (for example, diagonally 10 inches or less) incorporated in a dashboard or the like is applied. Further, the display panel 5
By displaying the inverted image of the image of the rear part of the vehicle body in 1, the driver 80 can drive the vehicle backward as if he / she is moving forward.

Further, as shown in FIG. 18 (B2), the lower end of the display panel 51 may be located below the surface 82 and inside the front field of view 83.

[Third form]
In FIG. 18C, the lower end of the display panel 51 of the display device 50 is above the surface 82.
Moreover, the case where it is located inside the front view 83 is shown. That is, the lower end of the display panel 51 is located higher than the height of the viewpoint 81 of the driver 80. By forming the display panel 51 in such a form, the driver 80 can visually recognize the front of the vehicle, and thus can drive in this state. Further, since the display panel 51 is located at the upper part of the field of view, the driver 80 can see the video and information displayed on the display panel 51 without significantly shifting the line of sight. At this time, on the display panel 51, in addition to the image around the vehicle body captured by the imaging means 72, map information, traffic information, information indicating the direction of travel, position information of the own vehicle, route and distance to the destination, and the like. It is preferable to display information such as estimated arrival time and information such as time, speed, and direction.

The above is the description of the form of the display device.

[Operation example]
Subsequently, FIG. 19 shows an example of the operation applicable to the driving support system of one aspect of the present invention.
Will be described with reference to. FIG. 19 shows a flowchart relating to the operation of the driving support system.

The operation is started in S10. At this time, the form of the display panel 51 is the second form or the third form.
It is assumed that it is in the form of. When the display panel 51 is in the third form, an image or the like may be displayed on the display panel 51. Further, in S10, the user may input the setting information that defines the operation of the control unit 71 by the input means 75 in advance.

In S11, the control unit 71 acquires the detection information from the detection means 73. If the detection information is backward, the process proceeds to S12. If the detection information is other than backward, S11 is repeated.

In S12, the control unit 71 reads the setting information stored in the storage device 74. The setting information includes information on whether or not to lower the display panel 51 when the detection information is backward.

In S13, the control unit 71 makes a determination based on the setting information. Specifically, when the setting information includes the information that the display panel 51 is lowered, the process proceeds to S14. On the other hand, when the information that the display panel 51 is not lowered is included, the process proceeds to S20 and the operation is terminated.

In S14, the control unit 71 transmits a signal to the drive means 52 to operate the display panel 51 so as to transform it into the first form. The drive means 52 is based on the signal, and the display panel 51
Is transformed from the second form or the third form to the first form.

Subsequently, in S15, the control unit 71 transmits a signal to start imaging to the imaging means 72. The imaging means 72 starts imaging and outputs the captured image information to the control unit 71.

In S16, the control unit 71 generates an image to be displayed on the display panel 51 based on the acquired image information, and transmits the image to the display panel 51. The image generated by the control unit 71 is displayed on the display panel 51.

Here, the driver 80 can drive the vehicle backward while watching the image displayed on the display panel 51.

Subsequently, in S17, the control unit 71 reacquires the detection information from the detection means 73. If the detection information is other than backward, the process proceeds to S18. If the detection information remains backward, the process returns to S16 to maintain the display.

In S18, the control unit 71 stops displaying on the display panel 51. Specifically, among the images displayed on the display panel 51, the display including at least the image captured by the imaging means 72 is stopped. Further, in S18, the control unit 71 transmits a signal to stop the imaging to the imaging means 72. The imaging means 72 stops imaging and output of a video signal. The imaging may be stopped and the display may be stopped at the same time, or either of them may be stopped first.

Subsequently, in S19, the control unit 71 transmits a signal to the drive means 52 to operate the display panel 51 so as to transform it into the second form. The drive means 52 transforms the form of the display panel 51 from the first form to the second form based on the signal.

In S19, the form of the display panel 51 at the time of S10 may be transformed. For example, if the display panel 51 is in the third form at the stage of S10, the display panel 5 is in S19.
The form 1 may be transformed into the third form. Further, the form of the display panel 51 to be deformed in S19 may be determined based on the setting information read in S12. For example, if the setting information stipulates that the third form be used, the display panel 51 may be transformed into the third form in S19.

The operation ends in S20. In S20, when the display panel 51 is in the second form, the display of the image or the like on the display panel 51 is stopped. On the other hand, when the display panel 51 is in the third form, an image or an image may be displayed in a region visible to the driver of the display panel 51.

Although the display panel 51 is used as the first mode when the vehicle is retracted here, various other operations can be performed.

For example, the control unit 71 may transmit a signal to the driving means 52 to operate the display panel 51 so as to change to the third form when the detection information is forward. At this time, the control unit 71
Started imaging by the imaging means 72, and the image was taken by the imaging means 72 in the rear and front of the vehicle.
An image generated based on at least one image information on the side may be displayed on the display panel 51.

The above is an explanation of an example of the operation of the driving support system.

[Display panel display]
Hereinafter, an image or an image that can be displayed on the display panel 51 will be described.

FIG. 20A shows a state in which the vehicle 60 is retracted and is about to be parked in the parking space 35. An imaging means 72 for imaging the rear of the vehicle 60 is attached to the rear portion of the vehicle 60. FIG. 20A shows the range of the image 31 captured by the imaging means 72. The parking space 35 is located inside a target object 36 such as a white line or a wheel chock that defines the parking space 35. Since the parking space 35 is not actually specified, it is indicated by a broken line.

FIG. 20 (B1) shows an example of the image 31 captured by the imaging means 72. Video 3
Reference numeral 1 denotes an image of the rear of the vehicle 60, and the image 31 shows the target object 36.

FIG. 20 (B2) shows an example of the image 32 displayed on the display panel 51. Video 32
Is a left-right inverted image of the image 31 captured by the imaging means 72. By displaying the left-right inverted image on the display panel 51 in this way, the driver 80 can perform an intuitive driving operation. That is, the left-right direction of the image 32 and the direction of the steering wheel operation can be matched. In particular, when the display panel 51 is the first form and is located in most of the field of view of the driver 80, the driver feels more immersive and realistic, so that the driver feels as if he / she is moving forward. , The operation of reversing the vehicle 60 can be performed.

Further, FIG. 20 (B2) shows an example in which a guide 37 indicating the traveling direction of the vehicle 60 is displayed. At this time, for example, the control unit 71 uses the information on the traveling direction of the vehicle 60, which is determined according to the current rotation angle of the steering wheel 64, as video information such as the guide 37, as the display panel 5
It can be displayed in 1.

Further, the control unit 71 analyzes the image 31 output from the imaging means 72 to visualize the information on the parking space 35 and the direction in which the vehicle 60 should travel as an image and display it on the image 32. Is preferable. FIG. 20 (B2) shows an example in which the area of the parking space 35 is visualized (with hatching in the figure) and displayed.

Further, FIG. 21A shows an example in which the direction in which the vehicle 60 should travel is represented and displayed by an image 38a imitating a steering wheel. The driver 80 can reliably advance the vehicle 60 toward the parking space 35 by operating the steering wheel 64 at the same angle as the steering wheel shown in the image 38a.

21 (B1) and 21 (B2) show another example of the image 38a. FIG. 21 (B1) shows an example in which the current state of the steering wheel 64 is displayed by a solid line, and the angle of the steering wheel 64 for directing the vehicle 60 in the direction in which the vehicle should travel is displayed by a dotted line. At this time, FIG. 2
As shown in 1 (B1), displaying an arrow or the like indicating the direction in which the handle 64 is operated (rotated) enables more intuitive operation. Further, when the driver 80 operates (rotates) the handle 64 so as to have an appropriate angle, as shown in FIG. 21 (B2), the image 38a
The steering wheel 64 is given to the driver 80 by changing the expression method such as blinking or changing the color.
It is preferable to clearly indicate that the angle is appropriate. Further, it may have a function of notifying the driver 80 by voice.

In this way, when the direction in which the vehicle 60 should travel is displayed on the display panel 51, for example, the control unit 71 analyzes the image 31 output from the imaging means 72, generates the image 38a, and displays the image 3.
It may be configured to have a function of superimposing 8a on the image 32 and outputting it to the display panel 51. More specifically, the control unit 71 recognizes the target object 36 displayed in the image 31, analyzes the relative positional relationship between the target object 36 and the vehicle 60 from the position of the target object 36, and obtains the result by the analysis. The configuration may be such that the direction in which the vehicle 60 should travel can be calculated from the information such as the distance obtained. Examples of the target object 36 that can be recognized by the control unit 71 include fixed objects such as white lines, wheel chocks, walls, steps, ruts, curbs, buildings, road signs, road markings, and creatures such as humans and animals. Also, moving objects such as vehicles such as automobiles and bicycles can be mentioned. For example, when the vehicle 60 and the target object 36 approach a predetermined distance or less, the steering wheel may be automatically turned or the brake may be applied.

Further, it is also possible to provide the imaging means 72 not only in the rear of the vehicle 60 but also in the front, side, etc., and display these images on the display panel 51.

FIG. 22A shows an example in which the vehicle 60 is provided with four imaging means. Vehicle 60
Imaging means 72a at the rear of the vehicle, imaging means 72b at the front of the vehicle, and imaging means 72 at the left side of the vehicle.
c, the imaging means 72d is fixed to the right side of the vehicle, respectively. The imaging means 72a is at the rear of the vehicle, the imaging means 72b is at the front of the vehicle, the imaging means 72c is at the left side of the vehicle, and the imaging means 72d.
Can image the right side of the vehicle. Here, the images captured by the imaging means 72a to 72d are referred to as images 31a to 31d.

FIG. 22 (B1) shows an example of an image displayed on the display panel 51. Video 32
The image 32b is displayed on the upper side, the image 32a is displayed on the lower side, the image 32c is displayed on the left side, and the image 32d is displayed on the right side. Here, the image 32b is an image in the same direction as the image 31b, the image 32a is an image obtained by reversing the image 31a left and right, and the image 32c is an image 31.
It is preferable that the image c is rotated 90 degrees counterclockwise, and the image 32d is an image obtained by rotating the image 31d 90 degrees clockwise. By displaying such an image 32 on the display panel 51, the driver 80 can intuitively grasp the situation around the vehicle 60. In addition, FIG.
As shown in 2 (B1), it is preferable to display the image 38b imitating the vehicle 60 near the center of the four images because the image can be more intuitively captured.

Further, as shown in FIG. 22 (B2), two adjacent images of the images 32a to 32d may be joined and displayed on the display panel 51 as one image 32e. At this time, it is preferable that the control unit 71 performs image processing for correcting the deviation and distortion that occur at the boundary between the two images.

The images shown in FIGS. 22 (B1) and 22 (B2) show the vehicle 60 except when the vehicle 60 is retracted.
Can be displayed on the display panel 51 even when the vehicle 60 is moved forward or when the vehicle 60 is stopped. In particular, when moving the vehicle 60 forward, if the image 32c on the left side of the vehicle 60 or the image 32d on the right side is displayed on the display panel 51, the driver 80 can see the situation in the range where the driver 80 is blind. Since it can be grasped, safety can be improved.

Although FIGS. 22 (B1) and 22 (B2) show a case where all four images of the vehicle are displayed on the display panel 51, the images from one or more imaging means may be displayed. In addition, an image pickup means for imaging the diagonally forward or diagonally rearward of the vehicle may be provided. Further, both the image from the imaging means and the image for navigation purposes such as map information may be displayed on the display panel 51 at the same time.

The above is the description of the display on the display panel.

This embodiment can be implemented in combination with at least a part thereof as appropriate with other embodiments described in the present specification.

(Embodiment 5)
In the present embodiment, an example of the display device of one aspect of the present invention will be described with reference to the drawings.

[Configuration Example 1]
FIGS. 23 (A) and 23 (B) show an example of the configuration of the display device 150 according to one aspect of the present invention.

The display device 150 includes a display panel 100, a shaft portion 151, a rotation mechanism 152, and a bearing portion 1.
53 and.

The display panel 100 has flexibility, and the display panel 100 is wound around the shaft portion 151 as shown in FIG. 23 (A), and the display panel 100 is suspended as shown in FIG. 23 (B). It can be transformed into a normal state.

The thickness of the display panel 100 is, for example, 10 μm or more and 5 mm or less, preferably 20 μm or more and 4 mm or less, more preferably 50 μm or more and 3 mm or less, and typically 100 μm or more and 2 mm.
The thickness can be as follows. The thinner the display panel 100, the more compact the size of the display device 150 when the display panel 100 is wound up. However, if the thickness is too thin, it is easily affected by wind and the like, and the machine of the display panel 100 There is a risk that the target strength will decrease. Further, for example, by having an appropriate thickness of about 0.5 mm or more and 5 mm or less, it is possible to suppress problems such as the display surface wavy even when the display panel 100 is suspended.
In addition, in order to prevent the display panel 100 from being curled in a suspended state, a member that functions as a weight as shown in FIG. 11 or the like may be attached to the lower end of the display panel 100. ..

The shaft portion 151 has a function of fixing one end of the display panel 100. In the shaft portion 151,
FPC (Flexible Printed Ci) that is electrically connected to the display panel 100
rcuit) etc. are arranged. Here, it is preferable that the shaft portion 151 is provided with a connector or wiring that electrically connects to the FPC. Further, the shaft portion 151 is a display panel 10.
It is preferable to provide a circuit for supplying a signal or voltage to 0. In addition, as a configuration having one or more of an antenna, a wireless receiver, a wireless transmitter, a power supply line, a battery, a printed circuit board on which an IC such as an arithmetic unit or a storage device is mounted, an external connection port, etc. on the shaft portion 151. May be good.

Here, the smaller the diameter of the shaft portion 151, the smaller the size of the display panel 100 when it is wound up. The diameter of the shaft portion 151 may be determined according to the curvature allowed when the display panel 100 is bent. For example, the diameter of the shaft portion 151 can be 0.1 mm or more and 50 mm or less, preferably 0.5 mm or more and 30 mm or less, more preferably 1 mm or more and 20 mm or less, and more preferably 2 mm or more and 10 mm or less. The diameter of the shaft portion 151 is 0.1 m.
By setting the value to m or more, it is possible to prevent the shaft portion 151 from bending due to the weight of the display panel 100. Further, by setting the diameter of the shaft portion 151 to 50 mm or less, the size of the display device 150 can be made sufficiently compact.

The rotation mechanism 152 has a function of rotating the shaft portion 151. The bearing portion 153 is a shaft portion 15.
It has a function to support 1. The rotation mechanism 152 may be configured to rotate the shaft portion 151 by, for example, a combination of power such as a motor and gears.

The rotating mechanism 152 corresponds to, for example, the driving means 52 illustrated in the third and fourth embodiments.

Further, it is preferable that wiring for supplying electric power or a signal to the FPC or the like in the shaft portion 151 is provided between the rotation mechanism 152 and the shaft portion 151. At this time, the wiring is the shaft portion 15.
Measures against twisting have been taken, such as wiring that is long enough or wiring that has been twisted in the direction opposite to the direction of rotation so that the wire will not be broken due to the twist that occurs when 1 is rotated. It is preferable to use wiring.

Alternatively, the rotation mechanism 152 and the shaft portion 151 may be configured to wirelessly transmit signals and electric power without providing wiring or reducing the number of wirings. For example, a wireless transmitter may be provided in the rotating mechanism 152, and a wireless receiver may be provided in the shaft portion 151 to transmit signals wirelessly. Further, a mechanism for transmitting electric power by using non-contact power feeding may be provided between the rotating mechanism 152 and the shaft portion 151. By doing so, it is possible to eliminate the risk of problems such as disconnection of the wiring, and it is possible to make the wiring highly reliable. Alternatively, the rotation mechanism 152
Signals and power may be supplied directly to the shaft portion 151 from other devices instead of from the body.

The display device 150 can appropriately adjust the length of the region where the display panel 100 is suspended, that is, the region that contributes to the display, by adjusting the amount of rotation of the shaft portion 151 by the rotation mechanism 152.

Although FIGS. 23 (A) and 23 (B) show a configuration in which the display unit 101 of the display panel 100 is wound around the shaft unit 151 so as to be on the outside, as shown in FIG. 23 (C), the display unit It may be configured to be wound around the shaft portion 151 so that 101 is on the inside. With such a configuration, it is possible to prevent the surface of the display unit 101 of the display panel 100 from physically coming into contact with other members.

The above is the description of the configuration example 1.

[Configuration Example 2]
Hereinafter, a configuration example of the display device having a configuration different from that of the configuration example 1 will be described.

The display device of one aspect of the present invention is a display device in which a plurality of support members having a band shape are provided on the back surface of a flexible display panel at intervals. The upper part of the display panel is fixed by a fixing portion. Further, among the plurality of support members, the support member located farthest from the fixed portion is connected to the cord. One end of the cord is connected to a take-up mechanism, which can take up the cord and pull out the cord.

The display device can be installed so as to suspend the display panel, for example. For example, the display surface of the display panel can be in a substantially flat state (first state). At this time, by winding the cord, the support member located farthest from the fixed portion can be moved to the fixed portion side. Then, the display panel located between the plurality of support members is curved, and the display panel can be deformed into a folded state (second state). Further, by pulling out the cord, it is possible to transform from the second state to the first state. That is, the state of the display panel can be changed between the first state and the second state.

Further, it is preferable that the cord has a function as a guide so that each of the plurality of support members moves in only one direction. By doing so, in the state where the display panel is folded, the support members are stacked substantially in parallel. Further, it is preferable that the cord has a function of adjusting the angle of the support member.

With such a configuration, the display panel located between two adjacent support members can be
Depending on the relative position of the two support members, it automatically (naturally) becomes curved with the optimum radius of curvature. Therefore, it is possible to prevent the display panel from being bent or damaged without applying an unreasonable external force to the display panel.

With the above configuration, the display panel can be folded while maintaining the optimum radius of curvature by simply displacing the support member farthest from the fixed portion in one direction with a cord. Further, it is preferable to adjust the angle of the support member as described above because the curved shape of the display panel can be controlled more precisely.

Further, it is preferable to provide an elastic cushioning material between the support member and the display panel. By making the width of the cushioning material larger than the width of the strip-shaped support member, it is possible to prevent the display panel from bending at the boundary between the area where the support member of the display panel is provided and the area where the support member is not provided. can do. In particular, it is preferable that the cushioning material has a shape or material such that the restoring force decreases as the distance from the support member increases. For example, the shape of the cushioning material is such that the thickness becomes thinner as the distance from the support member increases. By doing so, it is possible to more effectively suppress the problem that the display panel is bent near the end portion of the support member.

Further, the thicker the support member, the larger the radius of curvature when the display panel is curved, and the more the damage can be prevented.

Further, it is preferable that the plurality of support members are arranged at equal intervals. In particular, it is preferable to set the distance between the two support members to be larger than the width of the support members. As the distance between the support members increases, the area where the display panel can be curved increases, so that the stress applied to the display panel can be dispersed and the radius of curvature when the display panel is curved can be increased.

Further, the fixing portion for fixing the display panel may incorporate, for example, a circuit for supplying a power supply potential or a signal to the display panel. Further, when the fixed portion is arranged above, a hanging type display device using gravity can be obtained, but the present invention is not limited to this, and various forms can be obtained depending on the arrangement method of the fixed portion. For example, the display panel may be arranged so as to be folded in the horizontal direction (horizontal direction). At this time, when the display panel is unfolded, a mechanism for pulling the display panel in the lateral direction can be provided.

In the display device of one aspect of the present invention, the display panel can be housed by making the display surface flat when used and folding the display surface when not in use. Therefore, it is not necessary to secure an installation place as in the case of a conventional stationary television device or the like.
In addition, since a lightweight flexible panel is applied to the display panel, it is easy to carry the display panel in a folded state. Further, for example, in the case of a projection type display device (also referred to as a projector), both the screen and the main body are required, and in order to obtain a large image, the screen and the main body need to be separated to some extent. On the other hand, in the display device of one aspect of the present invention,
Since the image can be displayed on its own, a large image can be displayed even in a small room. In addition, since the display surface is compact when folded, it is easy to hide it with a drape, for example, and it can be made to look like a room without a display device, and a cleaner interior can be realized. ..

Further, in the display device of one aspect of the present invention, the display panel can be folded and stored without changing the position or orientation of the fixed portion. Here, for example, when considering a configuration in which the display panel itself is wound up to be compactly stored, the portion serving as the winding shaft corresponds to the fixed portion of one aspect of the present invention. Therefore, it is necessary to add a mechanism for rotating the fixed portion. Further, when a circuit or the like for driving the display panel is provided in the fixed portion and a connector or the like for electrically connecting the external and the fixed portion and the fixed portion and the display panel is provided, such a connector is fixed. Since a mechanism that can maintain an electrical connection even when the part is rotated is required, the configuration becomes complicated and it may cause a failure. On the other hand, in one aspect of the present invention, such a rotation mechanism is unnecessary, and the display panel can be compactly stored with an extremely simple configuration.

The display panels (light emitting panel, touch panel) exemplified in the first and second embodiments can be applied to the display panel. Therefore, the display device can be extremely reliable.

Further, the above-mentioned protective film not only suppresses the diffusion of impurities such as water, but also has the effect of increasing the mechanical strength of the display panel. For example, the hardness of the surface of the display panel can be increased to prevent scratches and the like. Further, by repeatedly bending the display panel, it is possible to prevent cracks and the like from being generated on the substrate and the like constituting the display panel.

More specifically, one aspect of the present invention can have the following configuration, for example.

24 (A) to 24 (C) show schematic perspective views of the display device 160 according to one aspect of the present invention. Figure 2
4 (A) shows a state in which the display surface is in a flat state, FIG. 24 (C) shows a state in which the display surface is folded, and FIG. 24 (B) shows FIGS. 24 (A) and 24 (C). ) Indicates the state between.

The display device 160 includes a display panel 100, a fixing portion 102, and support members 103a and 103b.
It has a cord 104, a winding mechanism 105, and the like. The display panel 100 has a display unit 101.

Here, as an example, the display device 16 used in a state where the display panel 100 is suspended.
An example of 0 is shown, but the hierarchical relationship is not limited, and it can be used horizontally. Also,
Here, the display unit 101 of the display panel 100 is shown so that the vertical direction (the direction perpendicular to the long side of the fixed portion 102) is the long side direction, but the present invention is not limited to this. For example, the display unit 101 may have a form in which the lateral direction of the display unit 101 (the direction parallel to the long side of the fixed portion 102) is the long side direction, or may be a square.

The display panel 100 has flexibility. Therefore, it is possible to reversibly transform the display panel 100 from a state in which the display surface is flat to a state in which the display surface has a curved surface. For example, the display panel 100 can be bent so that the display surface is on the inside (inward bending) or the display surface is on the outside (outward bending). Therefore, the display panel 100 can be folded. In the display panel 100, the portions supported by the support members 103a and 103b do not have to have flexibility.

The fixing portion 102 has a function of fixing the upper portion of the display panel 100 and suspending the display panel 100. The fixed portion 102 may be installed on, for example, the ceiling of a vehicle body, a wall or ceiling of a room, or the fixed portion 102 may be fixed to a frame or the like so as to be portable.

It is preferable that the fixing portion 102 and the display panel 100 are fixed so that their relative positions do not shift. For example, the fixing portion 102 and the display panel 100 may be fixed with screws, rivets, or the like, or these may be adhered with an adhesive or the like. Further, the fixed portion 102 is the display panel 100.
It may be configured to sandwich.

Further, in the fixed portion 102, an FPC or the like electrically connected to the display panel 100 is arranged. Here, it is preferable that the fixing portion 102 is provided with a connector or wiring that electrically connects to the FPC. Further, the fixing portion 102 preferably includes a circuit for supplying a signal or a voltage to the display panel 100. In addition, the fixed part 102 has an antenna, a wireless receiver,
It may be configured to have one or more of a wireless transmitter, a power supply line, a battery, a printed circuit board on which an IC such as an arithmetic unit or a storage device is mounted, an external connection port, and the like.

The support members 103a and 103b are provided on the side of the display panel 100 opposite to the surface of the display panel 100 on the display unit 101 side, and have a function of supporting the display panel 100. The support members 103a and 103b
It has a band-like shape. The support members 103a and 103b are arranged side by side and spaced apart from each other. Here, when the display surface is in a flat state, the support member located farthest from the fixing portion 102 is the support member 103a, and the other support members are the support member 1.
This will be described as 03b. Further, the long side on the surface of the support member 103a and the support member 103b overlapping the display panel 100 is called a long side, and the short side is called a short side. Also, the support member 103a
The direction perpendicular to the surface of the support member 103b that overlaps the display panel 100 is called the thickness direction.

It is preferable that the support members 103a and 103b and the display panel 100 are adhered to each other with, for example, an adhesive. Alternatively, these may be fixed by an adhesive member. If the area where the support members 103a and 103b and the display panel 100 are fixed is large, problems such as peeling of the support members 103a and 103b can be suppressed, which is preferable.

As the support members 103a and 103b, at least a material having a lower flexibility than the display panel 100 or a material having a higher rigidity can be used. Further, the support members 103a and 103a
When a material having a weight density lower than that of the display panel 100 is used for b, the support member 1
It is possible to suppress a problem that the display panel 100 is damaged due to the weights of 03a and 103b.
The materials used for the support members 103a and 103b are not particularly limited, but for example, metals, alloys, etc.
Various materials such as wood, paper, synthetic resin, glass, rubber and ceramic can be used. In particular, it is preferable to use plastic, an alloy containing titanium, or the like because it is lightweight. Further, the support members 103a and 103b may be reduced in weight by having a structure in which a hole is formed in a part of the sill or a structure having a cavity inside. Further, the support members 103a and 103b may have a flat surface at least in a portion supporting the display panel 100, and the other portions may have irregularities.

The cord 104 is connected to at least the support member 103a. The display device 160 has two or more cords 104 and is connected to both ends of the support member 103a so that the long side direction of the support member 103a is not tilted and is substantially perpendicular to the vertical direction. The support member 103a can be supported so as to be.

The support member 103a and the cord 104 may be fixed, for example, with an adhesive or the like, or may be fixed by connecting the cord 104 to the support member 103a. In addition, the support member 1
A through hole may be provided in 03a, and after the cord 104 is passed through the through hole, a member larger than the diameter of the through hole may be connected to the cord 104 to prevent the cord 104 from coming off.

Further, a winding mechanism 105 is provided on the upper part of the cord 104. By winding the cord 104 by the winding mechanism 105, the support member 103a can be moved to the upper side (fixed portion 102 side). Further, by pulling out the cord 104 by the winding mechanism 105, the support member 103a can be moved to the lower side (the side opposite to the fixing portion 102) by gravity.

The winding mechanism 105 may have various configurations as long as it has a function of winding the cord 104. For example, the winding mechanism 105 may be configured to have at least a rotating shaft fixed to the cord 104. Further, the winding mechanism 105 may be configured to wind the cord 104 by manually pulling the winding cord or the like, or may be provided with a motor or the like to electrically wind the cord 104. At this time, a wireless receiver or the like may be provided so that the remote controller can operate the device.

The winding mechanism 105 is, for example, the driving means 52 exemplified in the third embodiment and the fourth embodiment.
Corresponds to.

Further, although the winding mechanism 105 and the fixing portion 102 are shown separately here, they may be configured to fit in one housing.

By winding the cord 104 by the winding mechanism 105, the display device 160 is deformed from the state shown in FIG. 24 (A) to the state shown in FIG. 24 (B) and then to the state shown in FIG. 24 (C). Can be done. On the contrary, by pulling out the cord 104 by the winding mechanism 105, the display device 160 is deformed from the state shown in FIG. 24 (C) to the state shown in FIG. 24 (B) and then to the state shown in FIG. 24 (A). Can be made to. That is, the winding mechanism 105 can change the state of the display panel 100 between the state of FIG. 24 (A) and the state of FIG. 24 (C).

When the cord 104 is wound by the winding mechanism 105, the support member 103a moves upward. At this time, the display panel 100 is curved as the distance between the support member 103a and the support member 103b adjacent to the support member 103a becomes smaller. At this time, the external force applied to the display panel 100 is dominated by the force or gravity caused by the support member 103a and the support member 103b approaching each other, and no other external force is applied. Therefore, the display panel 100 is located between the two support members. It curves to a natural shape according to the relative position of. Therefore, it is possible to prevent the display panel 100 from being damaged by bending (or bending) beyond the allowable radius of curvature of the display panel 100 due to an unreasonable external force applied to the display panel 100.

Further, as shown in FIG. 24 (B), as the support member 103a moves, the other support member 103b naturally folds over the support member 103a. At this time, the distance between the support members is determined by the force (also referred to as the restoring force) that returns to the original shape when the display panel 100 is curved.
A certain distance is maintained. Therefore, it is possible to prevent the support members from coming too close to each other and prevent the display panel 100 from being damaged. If the restoring force of the display panel 100 is smaller than the weight of the support member 103b, the support members 103b or each other or the support member 10
It is preferable to provide a mechanism between the cord 104 and the support member 103b so that the distance between the 3a and the support member 103b does not become closer than a certain distance.

For example, when the support member 103a is pulled up from the state shown in FIG. 24 (A), the support member 103
A part of the display panel 100 between a and the support member 103b located at the bottom is curved.
Further, as the distance by which the support member 103a is pulled up increases, the curvature of the display panel 100 increases, and the restoring force of the display panel 100 increases accordingly. Here, since the support member 103b is not fixed to the cord 104 and can move in the vertical direction, the restoring force of the display panel 100 lifts the support member 103b located at the bottom. Then, in the same manner, the support member 103b located at the bottom and the support member 103b located next to it.
A part of the display panel 100 between and is curved. By pulling up the support member 103a with the cord 104 in this way, the display panel 100 can be deformed from the state of FIG. 24 (A) to the state of FIG. 24 (B) and then to the state of FIG. 24 (C). Here, the display panel 1
In the state where 00 is suspended, the radius of curvature of the curved portion of the display panel 100 may become smaller as it is closer to the lower side due to the influence of gravity.

Further, as shown in each figure of FIG. 24, it is preferable that the cord 104 is folded back by the support member 103a, and each support member 103b is sandwiched between the two parts of the cord 104. By doing so, the cord 104 can function as a guide so that each support member 103 moves only in the vertical direction.

Further, as shown in each figure of FIG. 24, assuming that the cord 104 has a band shape, the support member 10
3a and the support member 103b can be held more stably. The width of the code 104 is
For example, it can be 2 mm or more and 100 mm or less, preferably 5 mm or more and 50 mm or less, and more preferably 10 mm or more and 50 mm or less. Alternatively, it is preferable that the width of the cord 104 is thicker than the thickness of the support member 103a or the support member 103b. Especially code 104
When the width of the support member 103a or the support member 103b is set to 5 mm or more, problems such as rotation of the support member 103a or the support member 103b can be suppressed.

The form of the cord 104 is not limited to this, and for example, a string-shaped material may be used for the cord 104 and the cord 104 may be passed through a through hole provided in the support member 103b. Even in this case, the cord 104 can function as a guide for the support member 103b. At this time, one end of the string-shaped cord 104 is connected to the support member 103a, and the other end is wound by the winding mechanism 10.
It may be configured to be connected to No. 5 so that the cord 104 is not folded back.

Further, the winding mechanism 105 can adjust the angle of the support member 103a by winding one of the two ends of the folded cord 104 first. For example, FIG.
As shown in 4 (A), when the display surface of the display panel 100 is in a flat state, the support member 1
The short side direction of 03a is set to be the vertical direction, and as shown in FIGS. 24 (B) and 24 (C), when the display surface of the display panel 100 is folded, the short side direction and the vertical direction of the support member 103a are aligned. The angle can be adjusted to be greater than 0 degrees and less than 90 degrees. Support member 103
By setting the angle of a to an angle close to 90 degrees, the display panel 100 can be made more compact when folded.

As the code 104, for example, a material having higher flexibility (or higher flexibility) than the display panel 100 can be used. As the cord 104, for example, a fibrous material is preferable because it can be easily wound up. The material that can be used for the cord 104 is not particularly limited, but various materials such as natural fiber, synthetic fiber, paper, synthetic resin, rubber, fibrous metal or alloy can be used. Further, in FIG. 24 and the like, the cord 104 has a band shape, but the cord 104 may be in a form that can be wound by the winding mechanism 105, and is not limited to the band shape but has various shapes such as a string shape, a thread shape, and a chain shape. It can be in the form.

25 (A1) is a schematic view of the display device 160 in the state shown in FIG. 24 (B) as viewed from the side surface side, and FIG. 25 (A2) is surrounded by a alternate long and short dash line in FIG. 25 (A1). It is an enlarged view of the area. Further, FIG. 25 (B1) is a schematic view of the display device 160 in the state shown in FIG. 24 (C) as viewed from the side surface side, and FIG. 25 (B2) is a alternate long and short dash line in FIG. 25 (B1). It is an enlarged view of the enclosed area.

As shown in FIG. 25 (A2), in the region where the display panel 100 is flat, the two support members 103b are arranged at a distance D. At this time, it is preferable to arrange the distance between the two support members 103b and the distance between the support member 103b and the support member 103a at equal intervals. Alternatively, the spacing may be increased as it is closer to the upper side (fixed portion 102 side), or the spacing may be larger as it is closer to the lower side.

The distance D between the two support members 103b is preferably larger than the width W in the short side direction of the support member 103b. For example, the ratio (D / W) of the interval D to the width W can be larger than 1 and 30 or less, preferably 1.5 or more and 20 or less, and more preferably 2 or more and 15 or less.
The larger the interval D, the greater the degree of freedom in the curved shape of the display panel 100 when the display panel 100 is folded, so that damage to the display panel 100 can be suppressed. On the other hand, the smaller the interval D, the more compact the display panel 100 can be when folded. The distance between the support member 103a and the support member 103b is the same as the above distance D.
Further, when the distance D between the two support members 103b or the distance between the support member 103a and the support member 103b is reduced, it is preferable to increase the number of the support members 103b and arrange them densely.

The thickness T of the support member 103b is 1 mm or more and 30 mm or less, preferably 2 mm or more 2
It is preferably 0 mm or less, more preferably 3 mm or more and 15 mm or less. Support member 1
The thicker the 03b, the larger the radius of curvature when the display panel is curved, and the more the damage can be prevented. The support member 103a may have a thickness different from that of the support member 103b, or the same member may be used. The support member 103a located at the lowermost side may be decorated.

Further, as shown in FIG. 25 (B2), in the folded portion of the display panel 100, the display surface of the display panel 100 has a shape in which an inwardly curved portion and an outwardly curved portion are alternately positioned. It has become. Here, in the folded state of the display panel 100, the radius of curvature R of the portion of the curved portion of the display panel that is curved with the largest curvature is 1 mm or more and 5
It is preferably 0 mm or less, preferably 2 mm or more and 30 mm or less, and more preferably 4 mm or more and 20 mm or less.

Further, it is preferable that the support member 103a is adjusted to have a predetermined angle when the display panel 100 is folded. For example, as shown in FIG. 25 (B2), it is assumed that the angle between the short side direction O1 and the vertical direction O2 of the strip-shaped support member 103a is θ. At this time, the angle θ can be larger than 0 degrees and 90 degrees or less, preferably 10 degrees or more and less than 90 degrees, and more preferably 30 degrees or more and less than 90 degrees. The larger the angle θ, the more the display panel 10
0 can be folded compactly. The vertical direction O2 shown here is parallel to the direction (displacement direction) in which the support member 103a is moved by the cord 104.

Here, it is preferable to provide an elastic cushioning material between the display panel 100 and the support member 103a or 103b. FIG. 26 (A1) is an enlarged view of the vicinity of the end portion of the support member 103b when the cushioning material 106 is provided. The following description is the same for the support member 103a.

The cushioning material 106 is at least less flexible than the display panel 100, and the support member 10
It is preferable to use a material having higher flexibility than 3a or the support member 103b. Further, as the cushioning material 106, a material having a force (restoring force) for returning from the deformed state to the original state larger than that of the display panel 100 can be preferably used. As the cushioning material 106, an elastic body such as rubber, a metal plate having a function as a leaf spring, or the like can be preferably used. The thickness of these materials can be optimized to obtain the desired restoring force.

When the cushioning material 106 is applied, as shown in FIG. 26 (A2), in the portion P1 where the display panel 100 and the cushioning material 106 overlap, the display panel 1 is more than the portion P2 which does not overlap the cushioning material 106.
00 curves with a small curvature. Therefore, it is possible to effectively suppress problems such as the display panel 100 being bent at the end of the support member 103b.

Further, it is preferable that the cushioning material 106 has a shape or a material such that the restoring force becomes smaller as the distance from the support member 103b increases. For example, as shown in FIG. 26 (B1), the shape of the cushioning material 106 can be made thinner as it is farther from the support member 103b. At this time, as shown in FIG. 26 (B2), the portion P3 overlapping the cushioning material 106 of the display panel 100 has a curved shape such that the curvature becomes continuously larger (the radius of curvature becomes smaller) as the distance from the support member 103b increases. It becomes. Further, the portion P4 that does not overlap with the cushioning material 106 of the display panel 100.
Then, it curves with a curvature larger than the region P3. At this time, the sharper the angle of the end portion of the cushioning material 106 (that is, the smaller the angle), the more the curvature becomes continuous between the region P3 and the region P4, which is preferable.

Further, as shown in FIG. 27 (A), a cushioning material 106a may be provided in a portion close to the support member 103b, and a cushioning material 106b having a restoring force smaller than that of the cushioning material 106a may be provided in a portion far away. Further, as shown in FIG. 27 (B), the cushioning material 106a and the cushioning material 106b may be laminated so that the width of the cushioning material 106b is larger than that of the cushioning material 106a. Although two cushioning materials having different restoring forces are used here, three or more cushioning materials having different restoring forces may be used, or two or more cushioning materials having the same restoring force may be laminated and used.

The above is the description of the configuration example 1.

[Modification example]
In the above configuration example 1, the support member 103a farthest from the fixing portion 102 by the cord 104.
Although the display panel 100 is folded by pulling up the support member 103a, a plurality of support members 103b may be pulled up at the same time in addition to the support member 103a. Examples of this case are shown in FIGS. 28 (A) and 28 (B). FIG. 28 (A) is a schematic perspective view of the stage in which the display panel 100 is being folded, and FIG. 28 (B) is a schematic perspective view of the display panel 100 in a folded state.

Although the code 104 and the like are not specified in FIGS. 28 (A) and 28 (B) for clarification, the code 104, the support member 103, and each support member 103b are the code 10 of the configuration example 1.
The connection relationship between 4 and the support member 103a can be used. That is, the support member 103a
, And a plurality of cords connecting each of the plurality of support members 103b may be configured.

Further, as shown in FIGS. 29 (A) and 29 (B), the display panel 100 may be folded by adjusting the angles of the two adjacent support members so as to be tilted to the opposite sides.

The above is the description of the modified example.

[Application example]
The display device of one aspect of the present invention can be applied to various places such as indoors in addition to being attached to the interior of an automobile as illustrated in the third embodiment.

FIG. 30A shows an example in which the display device 10 of one aspect of the present invention is installed on the wall 15 of the room. As the display device 10, the display device 150 or the display device 160 can be applied.
30 (A) and 30 (B) show a configuration having a winding cord 11 interlocked with a winding mechanism (not shown) of the display device 10. By pulling the take-up cord 11, the display panel of the display device 10 can be deformed into a folded state and a display surface of the display panel in a flat state. Further, a cover 16 for storing a fixed portion (not shown) is provided on the upper part of the display device 10, and the display panel can be folded and stored. FIG. 30B shows a state in which the display device is housed in the cover 16. When the display device 10 is not used, as shown in FIG. 30 (B), the entire display device 10 in a state where the display panel is folded is hidden by the cover 16, and a cleaner interior can be realized.

Further, in FIGS. 30A and 30B, a table 20 having a display device 10 according to an aspect of the present invention is shown.
Is shown. Further, a schematic cross-sectional view of the table 20 is shown in FIGS. 30 (C) and 30 (D). Table 2
0 has a display device 10 inside the housing 21, and a translucent cover 2 on the upper surface of the housing 21.
Has 2. For the cover 22, for example, glass or plastic may be used. FIG. 30
As shown in (C), when the display surface of the display device 10 is flat, the image displayed on the display surface can be seen through the cover 22. When the display device 10 is not used, the display panel of the display device 10 can be folded and stored in a portion not covered by the cover 22 as shown in FIG. 30 (D) to be used as a normal table. Can be done.

Here, an example in which the display device of one aspect of the present invention is installed inside a wall or a table in a room is shown, but the present invention is not limited to this, and it can be arranged in various places. For example, it may be installed on the ceiling, floor, table, pillar, or the like of a general household or a conference room. In addition to moving objects such as automobiles, buses, trains, and airplanes, it can be installed in various things such as commercial facilities and spaceships. Further, by attaching the display device to the foldable frame or the like as described above, it can be used anywhere.

The above is the description of the application example.

This embodiment can be implemented in combination with at least a part thereof as appropriate with other embodiments described in the present specification.

(Embodiment 6)
In the present embodiment, an example of a touch panel driving method applicable to the display panel included in the display device of one aspect of the present invention will be described with reference to the drawings.

[Example of sensor detection method]
FIG. 31 (A) is a block diagram showing a configuration of a mutual capacitance type touch sensor. FIG. 31
In (A), the pulse voltage output circuit 601 and the current detection circuit 602 are shown. Note that FIG. 31
In (A), the electrode 621 to which the pulse voltage is applied and the electrode 622 that detects the change in the current are shown as six wirings of X1-X6 and Y1-Y6, respectively. In addition, FIG. 31 (
A) illustrates the capacitance 603 formed by the superposition of the electrodes 621 and 622. The functions of the electrode 621 and the electrode 622 may be interchanged with each other.

The pulse voltage output circuit 601 is a circuit for sequentially applying a pulse voltage to the wirings of X1-X6. When a pulse voltage is applied to one of the wirings of X1-X6, an electric field is generated in the electrodes 621 and 622 forming the capacitance 603. By utilizing the fact that the electric field generated between the electrodes causes a change in the capacitance of the capacitance 603 due to shielding or the like, it is possible to detect that the object to be detected approaches, contacts, presses, or the like.

The current detection circuit 602 is a circuit for detecting a change in current in the wiring of Y1-Y6 due to a change in capacity in capacity 603. In the wiring of Y1-Y6, there is no change in the current value detected if there is no proximity or contact of the object to be detected, but if the capacity decreases due to the proximity or contact of the object to be detected, the current Detect changes that decrease in value. The current may be detected by using an integrator circuit or the like.

Next, FIG. 31 (B) shows a timing chart of input / output waveforms in the mutual capacitance type touch sensor shown in FIG. 31 (A). In FIG. 31B, it is assumed that the detected object is detected in each matrix in one frame period. Further, in FIG. 31 (B), when the object to be detected is not detected (
Two cases are shown: non-touch) and detection of the object to be detected (touch). The Y1-Y6 wiring shows a waveform with a voltage value corresponding to the detected current value.

A pulse voltage is sequentially applied to the wiring of X1-X6, and Y1- according to the pulse voltage.
The waveform in the Y6 wiring changes. X1-X6 when there is no proximity or contact with the object to be detected
The waveform of Y1-Y6 changes uniformly according to the change of the voltage of the wiring. On the other hand, since the current value decreases at the location where the object to be detected is close to or in contact with the object to be detected, the corresponding voltage value waveform also changes.

By detecting the change in capacitance in this way, the proximity or contact of the object to be detected can be detected.

Further, although FIG. 31 (A) shows the configuration of a passive matrix type touch sensor in which only the capacitance 603 is provided at the intersection of the wirings as the touch sensor, an active matrix type touch sensor having a transistor and a capacitance may be used. .. FIG. 32 shows an example of one sensor circuit included in the active matrix type touch sensor.

The sensor circuit has a capacitance 603, a transistor 611, a transistor 612, and a transistor 613. Transistor 613 is given a signal G2 to the gate, voltage VRES is given to one of the source or drain, and the other is electrically connected to one electrode of capacitance 603 and the gate of transistor 611. One of the source and drain of the transistor 611 is electrically connected to one of the source and drain of the transistor 612, and the voltage V is connected to the other.
SS is given. A signal G1 is given to the gate of the transistor 612, and the other of the source and the drain is electrically connected to the wiring ML. A voltage VSS is applied to the other electrode of capacitance 603.

Subsequently, the operation of the sensor circuit will be described. First, the transistor 613 as the signal G2
By giving the potential to turn on, the potential corresponding to the voltage VRES is given to the node n to which the gate of the transistor 611 is connected. Next, the potential for turning off the transistor 613 is given as the signal G2, so that the potential of the node n is maintained.

Subsequently, the potential of the node n changes from VRES as the capacity of the capacity 603 changes due to the proximity or contact of the object to be detected such as a finger.

The read operation gives the signal G1 a potential to turn on the transistor 612. The current flowing through the transistor 611, that is, the current flowing through the wiring ML changes according to the potential of the node n. By detecting this current, the proximity or contact of the object to be detected can be detected.

As the transistor 611, the transistor 612, and the transistor 613, it is preferable to use a transistor in which an oxide semiconductor is applied to a semiconductor layer on which a channel is formed. In particular, by applying such a transistor to the transistor 613, the potential of the node n can be maintained for a long period of time, and the frequency of the operation (refresh operation) of resupplying the voltage VRES to the node n can be reduced. Can be done.

This embodiment can be implemented in combination with at least a part thereof as appropriate with other embodiments described in the present specification.

[Structure example 1 of laminated panel]
The laminated panel 40 of one aspect of the present invention includes a plurality of the above-mentioned display panels 400. FIG. 33
(B) shows a schematic top view of a laminated panel 40 including three display panels.

In the following, when each display panel, each component included in each display panel, or each component related to each display panel will be described separately, an alphabet will be added after these symbols. Unless otherwise specified, for the display panel and its components arranged on the lowermost side (opposite to the display surface) among the plurality of display panels partially overlapped with each other. The code "a" is added, and the alphabet is added in alphabetical order after the code for one or more display panels and their components arranged in order on the upper side thereof. Further, unless otherwise specified, even when explaining a configuration including a plurality of display panels, when explaining matters common to each display panel or component, the alphabet is omitted. ..

The laminated panel 40 shown in FIG. 33B includes a display panel 400a, a display panel 400b, and a display panel 400c.

A part of the display panel 400b is arranged so as to be overlapped on the upper side (display surface side) of the display panel 400a. Specifically, the display area 401a of the display panel 400a and the display panel 400
The area 410b that transmits visible light of b overlaps with the display area 4 of the display panel 400a.
The 01a and the region 420b that blocks visible light of the display panel 400b are arranged so as not to overlap each other.

A part of the display panel 400c is arranged so as to be overlapped on the upper side (display surface side) of the display panel 400b. Specifically, the display area 401b of the display panel 400b and the area 410c that transmits visible light of the display panel 400c overlap, and the display area 401b of the display panel 400b and the area 420c that blocks the visible light of the display panel 400c. And are arranged so as not to overlap.

Since the area 410b that transmits visible light is superimposed on the display area 401a, the display area 40
The entire 1a can be visually recognized from the display surface side. Similarly, the entire display area 401b can be visually recognized from the display surface side by superimposing the area 410c on the display area 401b. Therefore,
The area in which the display area 401a, the display area 401b, and the display area 401c are seamlessly arranged can be used as the display area 41 of the laminated panel 40.

[Structure example 2 of laminated panel]
Although FIG. 33 (B) shows a configuration in which a plurality of display panels 400 are stacked and arranged in one direction,
A plurality of display panels 400 may be stacked and arranged in two directions, a vertical direction and a horizontal direction.

FIG. 34 (A) shows an example of the display panel 400 in which the shape of the region 410 is different from that of FIG. 33 (A). In the display panel 400 shown in FIG. 34 (A), a region 410 that transmits visible light is arranged along two sides of the display region 401.

FIG. 34 (B) shows a schematic perspective view of a laminated panel 40 in which two display panels 400 shown in FIG. 34 (A) are arranged vertically and two horizontally. Further, FIG. 34 (C) is a schematic perspective view of the laminated panel 40 when viewed from the side opposite to the display surface side.

In FIGS. 34 (B) and 34 (C), a region along the short side of the display region 401a of the display panel 400a and a part of the region 410b of the display panel 400b are provided so as to overlap each other. Further, a region along the long side of the display region 401a of the display panel 400a and a part of the region 410c of the display panel 400c are provided so as to overlap each other. Further, the area 410d of the display panel 400d is
It is provided so as to be superimposed on the area along the long side of the display area 401b of the display panel 400b and the area along the short side of the display area 401c of the display panel 400c.

Therefore, as shown in FIG. 34 (B), the area in which the display area 401a, the display area 401b, the display area 401c, and the display area 401d are seamlessly arranged can be used as the display area 41 of the laminated panel 40.

Here, it is preferable that a flexible material is used for the pair of substrates used for the display panel 400, and the display panel 400 has flexibility. By doing so, for example, FIG. 34 (B),
As shown in the display panel 400a in (C), when the FPC412a or the like is provided on the display surface side, a part of the display panel 400a on the side where the FPC412a is provided is curved to form the FPC4.
12a can be arranged so as to overlap the display area 401b of the adjacent display panel 400b. As a result, the FPC 412a can be arranged without physically interfering with the back surface of the display panel 400b. In addition, the display panel 400a and the display panel 400
Since it is not necessary to consider the thickness of the FPC 412a when the b is overlapped and adhered, the difference in height between the upper surface of the display area 410b of the display panel 400b and the upper surface of the display area 401a of the display panel 400a can be reduced. .. As a result, it is possible to prevent the end portion of the display panel 400b located on the display area 401a from being visually recognized.

Further, by making each display panel 400 flexible, the height of the upper surface of the display panel 400b in the display area 401b is matched with the height of the upper surface of the display panel 400a in the display area 401a. Can be gently curved. Therefore, the heights of the respective display areas can be made uniform except for the vicinity of the area where the display panel 400a and the display panel 400b overlap, and the display quality of the image displayed in the display area 41 of the laminated panel 40 can be improved. ..

In the above, the relationship between the display panel 400a and the display panel 400b has been described as an example, but the same applies to two adjacent display panels.

Further, in order to reduce a step between two adjacent display panels 400, it is preferable that the thickness of the display panel 400 is thin. For example, the thickness of the display panel 400 is 1 mm or less, preferably 3.
It is preferably 00 μm or less, more preferably 100 μm or less.

Although the configuration in which four display panels 400 are laminated is shown here, an extremely large laminated panel can be obtained by increasing the number of display panels 400. Further, by changing the arrangement method of the plurality of display panels 400, the outline shape of the display area of the laminated panel can be made into various shapes such as a circle, an ellipse, and a polygon. Further, by arranging the display panel 400 in three dimensions, it is possible to realize a laminated panel having a display area having a three-dimensional shape.

This embodiment can be implemented in combination with at least a part thereof as appropriate with other embodiments described in the present specification.
