For example, you may provide in the surface where the display part 500 and the touch sensor 600 were bonded together, the display part 500, or the inside of the touch sensor 600. FIG. In addition, the sign portion 104b may be provided on the side surface of the touch panel 500TP. FIG. 9A is a perspective view and FIG. 9B is a top view of the information processing apparatus 100 in which the sign 104b is provided on the side surface of the touch panel 500TP. As shown in FIG. 9, the region 101 can be widened by providing the marking portion 104b on the side surface of the touch panel 500TP.

Various shapes can be used as the label Pt. As long as the shape of the label Pt can be detected by the detection element 104a, any shape may be used. Moreover, it is preferable that the label | marker Pt has a different shape. For example, a one-dimensional code such as a barcode or a two-dimensional code such as a QR code (registered trademark) can be used. Also, numbers, letters, symbols, figures, colors, etc. can be used as the label Pt.

A plurality of markers Pt having different shapes are provided at various positions on the marker 104b provided on the touch panel 500TP. When the touch panel 500TP is wound around the winding unit 106, the relative positional relationship between the detection element 104a and the touch panel 500TP changes, so the label Pt detected by the detection element 104a also changes. Therefore, it is possible to obtain information on the state of the touch panel 500TP, specifically, the area wound around the winding unit 106 of the touch panel 500TP, from the type of the label Pt detected by the detection element 104a.

For example, when the label Pt_h1 and the label Pt_h2 are arranged in the label unit 104b as illustrated in FIG. 4A, when the detection element 104a detects the label Pt_h1, the information processing apparatus 100 is in a state as illustrated in FIG. When the detection element 104a detects the sign Pt_h2, it can be seen that the information processing apparatus 100 is in the state shown in FIG.

Further, for example, the drive unit 103 or the calculation unit 110 holds data indicating which type of label Pt is located at which position on the touch panel 500TP, so that the touch panel 500TP can be determined from the type of the label Pt detected by the detection element 104a. It is possible to calculate the area that is wound around the winding section 106.

Moreover, when obtaining the 1st information which concerns on the state of the touch panel 500TP by the number of the label | markers Pt which the detection element 104a detects when the touch panel 500TP is wound up by the winding-up part 106, the shape of several label | markers Pt is It may be the same. For example, when h signs Pt provided in the sign section 104b are sequentially detected, the state in which h1 signs Pt are detected is different from the state in which h2 is detected. Accordingly, the number of detected signs Pt is the first information related to the state of the touch panel 500TP. In this case, the detection element 104a preferably has a function of determining whether the touch panel 500TP is wound around the winding unit 106 or conversely spread from the winding unit 106. For example, when a camera is used as the detection element 104a, it is possible to determine whether the touch panel 500TP is wound around the winding unit 106 or spread from the winding unit 106 according to the direction in which the marker Pt moves in the image. I can do it.

<Configuration Example 2 of Detection Unit>
The detection unit 104 of this configuration example includes a mechanism that detects the degree of rotation of the winding unit 106 with respect to the housing 105. Note that the degree of rotation of the winding unit 106 with respect to the housing 105 is the total number or the total number of rotations or rotation angles of the winding unit 106 relative to the housing. For example, the degree of rotation of the winding unit 106 with respect to the housing 105 is the number of rotations or the total rotation angle of the winding unit 106 based on the state where the touch panel 500TP is not wound around the winding unit 106. Point to. Therefore, when the rotation is once stopped and then rotated again, the total of all the rotations is set as the degree of rotation. When summing up, if the rotation in the direction of winding the touch panel 500TP on the winding unit 106 is positive, the rotation in the spreading direction is calculated as negative. Plus and minus may be interchanged.

As the detection unit 104, any detection unit 104 may be used as long as it can detect the degree of rotation of the winding unit 106 with respect to the housing 105. For example, a potentiometer that can detect rotation can be used. At that time, it is preferable to use a potentiometer capable of detecting a plurality of rotations.

In this configuration example, information regarding the degree of rotation of the winding unit 106 with respect to the housing 105 obtained by the detection unit 104 is supplied to the driving unit 103 or the calculation unit 110.

In addition, the driving unit 103 drives the touch sensor 600 based on the first information supplied from the detection unit 104. Alternatively, based on the first information supplied from the detection unit 104 and information such as the diameter of the winding unit 106 and the thickness of the touch panel 500TP, the region wound around the winding unit 106 of the touch panel 500TP is calculated, The touch sensor 600 provided in an area that is not wound around the winding portion 106 of the touch panel 500TP is driven. Alternatively, the first information is supplied from the detection unit 104 to the calculation unit 110, and the calculation unit 110 uses the first information and information such as the diameter of the winding unit 106 and the thickness of the touch panel 500TP to wind the touch panel. The area wound up by the take-up unit 106 is calculated. The second information calculated by the calculation unit 110 is supplied to the driving unit 103, and the driving unit 103 is based on the second information and is provided in a region that is not wound around the winding unit 106 of the touch panel 500TP. The sensor 600 is driven.

Note that in this specification, the first information or the second information related to the state of the touch panel 500TP refers to all information related to the state of the touch panel 500TP. The first information or the second information may be information that can know the state of the touch panel 500TP by being combined with other information. The information that can know the state of the touch panel 500TP by combining with other information is, for example, the type of the label Pt detected by the detection element 104a shown in the configuration example 1 of the detection unit. The type of the label Pt detected by the detection element 104a is compared with the data indicating which type of label Pt is present at which position of the label part provided on the touch panel 500TP, specifically, the state of the touch panel 500TP. The area wound up by the winding unit 106 of the touch panel 500TP can be calculated.

Further, the first information or the second information related to the state of the touch panel 500TP may be directly related to driving of the touch sensor 600 that is driven based on the state of the touch panel 500TP. For example, information on which control line is supplied with a control signal and which control line is not supplied, or which signal line detection signal is used and which signal line is used, which will be described later in Embodiment 3. Information such as whether or not to use the detection signal may be used. When the first information or the second information is sent from the detection unit 104 to the drive unit 103, the touch sensor 600 is limited and driven without calculating the state of the touch panel 500TP in combination with other information. I can do it.

<Operation of information processing device>
Hereinafter, an operation of the information processing apparatus 100 when the touch panel 500TP is partially wound on the winding unit 106 will be described.

(First step)
By the rotation mechanism provided in the housing 105, the winding unit 106 is rotated with respect to the housing 105, and the touch panel 500TP is partially wound around the winding unit 106 (see FIG. 4B). Here, the region 500TP_2 shown in FIGS. 4B and 4C is not wound around the winding portion 106.

(Second step)
The detection unit 104 determines the state of the touch panel. Thereby, the detection unit 104 obtains the first information related to the state of the touch panel. Specifically, the detection unit 104 obtains first information relating to an area wound around the winding unit 106 of the touch panel 500TP. The above information varies depending on the configuration of the detection unit 104. For example, in the above-described configuration example 1 of the detection unit, as illustrated in FIG. 4B, the detection element 104a detects the label Pt_h1. The information related to the label Pt_h1 is first information related to the state of the touch panel 500TP, specifically, first information related to a region wound around the winding unit 106 of the touch panel 500TP.

(Third step)
The detection unit 104 supplies the first information related to the state of the touch panel 500TP obtained in the second step to the drive unit 103. Specifically, the detection unit 104 supplies the first information related to the area wound up by the winding unit 106 of the touch panel 500TP.

Or the detection part 104 may supply the 1st information which concerns on the state of a touch panel to the calculating part 110. FIG. The computing unit 110 calculates the second information related to the state of the touch panel based on the first information, and then supplies the second information to the driving unit. Specifically, the detection unit 104 supplies the first information related to the area wound around the winding unit 106 of the touch panel 500TP to the calculation unit 110. The calculation unit 110 calculates the second information related to the area wound around the winding unit 106 of the touch panel 500TP based on the first information, and then supplies the second information to the driving unit.

(Fourth step)
The drive unit 103 drives a part of the touch sensor 600 based on the first information or the second information. Specifically, the drive unit 103 drives the touch sensor 600 provided in an area that is not wound around the winding unit 106 of the touch panel 500TP. In addition, the drive unit 103 does not drive the touch sensor 600 provided in the region wound around the winding unit 106 of the touch panel 500TP. For example, the touch sensor 600 provided in the region 500TP_2 shown in FIG. 4C is driven, and the touch sensor 600 provided in the region 500TP_1 is not driven. Note that, as described above, FIG. 4C is a diagram illustrating a state in which the touch panel 500TP illustrated in FIG.

Moreover, it is not necessary to drive the whole area | region which is not wound up by the winding-up part 106 of the touchscreen 500TP. That is, the range in which the touch sensor 600 is driven may be adjusted in a region that is not wound around the winding unit 106 of the touch panel 500TP. For example, in a configuration in which the winding unit 106 is provided in the casing 105, the area accommodated in the casing 105 of the touch panel 500TP may be wider than the area wound around the winding unit 106 of the touch panel 500TP. . For example, when a roller 108 or the like is provided in the housing 105, the touch sensor 600 is in a region that is not wound around the winding unit 106 of the touch panel 500TP so as to avoid a region where the roller 108 or the like contacts the touch panel. The driving range may be determined. Further, the driving unit 103 drives the touch sensor 600 provided in an area not accommodated in the casing 105 of the touch panel 500TP, and drives the touch sensor 600 provided in an area accommodated in the casing 105 of the touch panel 500TP. You don't have to. For example, the touch sensor 600 provided in the region 500TP_4 illustrated in FIG. 6B is driven, and the touch sensor 600 provided in the region 500TP_3 is not driven. Further, the drive unit 103 may determine a region where the touch sensor 600 is driven and a region where the touch sensor 600 is not driven based on the detection element 104a. For example, the touch sensor 600 provided in the region 500TP_6 illustrated in FIG. 6D is driven, and the touch sensor 600 provided in the region 500TP_5 is not driven.

The details of the method in which the driving unit 103 drives a part of the touch sensor 600 will be described in Embodiment 3.

Further, the display unit 500 provided in an area that is not wound around the winding unit 106 of the touch panel 500TP is driven, and the display unit 500 provided in the area that is wound around the winding unit 106 of the touch panel 500TP is driven. It is not necessary.

The display area of the display unit 500 can be limited based on the first information relating to the area wound around the winding unit 106 of the touch panel 500TP supplied from the detection unit 104. Alternatively, the display area of the display unit 500 can be limited based on the second information related to the area wound around the winding unit 106 of the touch panel 500TP supplied from the calculation unit 110. For example, only the display unit 500 provided in an area that is not wound around the winding unit 106 of the touch panel 500TP is driven. Or only the display part 500 with which the area | region which is not accommodated in the housing | casing 105 of the touchscreen 500TP was equipped is driven.

When the area for driving the display unit 500 is limited, the image may be converted so that the entire image can be seen in the area that is not wound around the winding unit 106 of the touch panel 500TP. Further, it is not necessary to display an image on the entire display unit provided in an area that is not wound around the winding unit 106 of the touch panel 500TP. The display area may be changed according to the aspect ratio of the image. Further, the orientation of the image may be changed. For example, in order to display the image to the maximum extent, the image may be displayed rotated by 90 degrees. For example, when the original image is longer in the horizontal direction than in the vertical direction but the display area is shorter in the horizontal direction than the vertical direction, the image can be displayed larger by rotating the image by 90 degrees. Alternatively, the orientation of the image may be detected by a sensor such as a MEMS (microelectromechanical system) such as a touch panel, and the image may be converted so that the upper side of the predetermined information processing apparatus 100 is aligned with the upper side of the image. In addition, when converting an image so that the entire image can be seen, it is preferable to limit the display area so as to match the aspect ratio of the original image. Further, the display area may be limited to the number of pixels and the area where the image can be easily converted.

When the display area is changed, the area for driving the touch sensor 600 may be changed according to the display area.

(Embodiment 2)
In this embodiment, a structure of the touch panel 500TP according to one embodiment of the present invention will be described with reference to FIGS. Note that here, the configuration of the touch panel 500TP will be described, but the indicator 104b provided on the touch panel 500TP will not be described. The sign portion 104b can be provided at the appropriate position described in Embodiment 1.

FIG. 10 illustrates a structure of the touch panel 500TP of one embodiment of the present invention. For convenience of explanation, a part of the touch sensor 600 and a part of the pixel 502 are shown enlarged.

11A is a cross-sectional view taken along line Z1-Z2 of the touch panel 500TP of one embodiment of the present invention illustrated in FIG. 10, and FIGS. 11B and 11C are illustrated in FIG. It is sectional drawing which shows the modification of a part of structure.

A touch panel 500TP described in this embodiment includes a display portion 500 and a touch sensor 600 that overlaps the display portion 500 (see FIG. 10).

The touch panel 500TP is connected to the winding unit 106 provided in the housing 105. Further, the touch panel 500TP is accommodated in the housing 105 by being wound around the winding portion 106 (see FIGS. 1 and 2).

The first electrode C <b> 1 (i) or the second electrode C <b> 2 (j) includes a mesh-like conductive film including an opening 667 in a position overlapping with the pixel 502.

For example, the touch sensor 600 of the touch panel 500TP can detect the detection information and supply it together with the position information. Specifically, the user of the touch panel 500TP can perform various gestures (such as tap, drag, swipe, or pinch-in) using a finger or the like that is in proximity to or in contact with the touch sensor 600 as a pointer.

The touch sensor 600 can detect a finger or the like approaching or touching the touch sensor 600 and supply detection information including the detected position or locus.

The arithmetic device determines whether the supplied information satisfies a predetermined condition based on a program or the like, and executes a command associated with a predetermined gesture.

Thereby, the user of the touch sensor 600 can supply a predetermined gesture and cause the arithmetic device to execute a command associated with the predetermined gesture. Note that the above-described arithmetic unit 110 can also be used as the arithmetic device or included in the arithmetic device.

Further, for example, the arithmetic device or the like supplies the display information V, and the display unit 500 of the touch panel 500TP is supplied with the display information V.

In addition to the above configuration, the touch panel 500TP may include the following configuration.

The touch sensor 600 of the touch panel 500TP may be electrically connected to the flexible printed circuit board FPC1.

The display unit 500 of the touch panel 500TP may include a driver circuit 503g, a driver circuit 503s, a wiring 511, or a terminal 519. Moreover, you may electrically connect with flexible printed circuit board FPC2.

Further, a protective layer 670 may be provided that prevents the generation of scratches and protects the touch panel 500TP. For example, a ceramic coat layer or a hard coat layer can be used for the protective layer 670. Specifically, a layer containing aluminum oxide or a UV curable resin can be used. Further, the antireflection layer 670p that weakens the intensity of external light reflected by the touch panel 500TP can be used. Specifically, a circularly polarizing plate or the like can be used.

Below, each element which comprises touch panel 500TP is explained. Note that these configurations cannot be clearly separated, and one configuration may serve as another configuration or may include a part of another configuration.

For example, the touch sensor 600 including a colored layer at a position overlapping with the plurality of openings 667 is the touch sensor 600 and a color filter.

For example, the touch panel 500TP in which the touch sensor 600 is superimposed on the display unit 500 is the touch sensor 600 and the display unit 500.

<Overall configuration>
Touch panel 500TP described in this embodiment includes touch sensor 600 or display unit 500.

Note that an example of a method for manufacturing a stacked body that can be used for manufacturing the touch panel 500TP will be described in detail in Embodiments 4 to 6.

《Touch sensor》
The touch sensor 600 includes a control line CL (i), a signal line ML (j), or a flexible substrate 610.

Note that the touch sensor 600 may be manufactured using a method of forming a film for forming the touch sensor 600 over the flexible substrate 610 and processing the film.

Alternatively, the touch sensor 600 may be manufactured using a method in which a part of the touch sensor 600 is formed on another base material and the part is transferred to the flexible substrate 610.

The touch sensor 600 detects a proximity or touching object and supplies a detection signal. For example, capacitance, illuminance, magnetic force, radio wave, pressure, or the like is detected, and information based on the detected physical quantity is supplied. Specifically, a capacitive element, a photoelectric conversion element, a magnetic sensing element, a piezoelectric element, a resonator, or the like can be used as the sensing element of the touch sensor 600.

As the touch sensor 600, for example, a capacitance method, a resistance film method, an optical method, a surface acoustic wave method, an electromagnetic induction method, or the like can be used. Capacitive touch sensors are classified into a projection type and a surface type, and the projection type is further classified into a self-capacitance method and a mutual capacitance method. Further, as the touch sensor 600, an active matrix method using an active element such as a transistor can be used.

For example, a capacitive touch sensor detects a change in capacitance between a detection target such as a finger or a stylus pen and a conductive film included in the touch sensor 600. In the case of the mutual capacitance method, which is one of the projected capacitive methods, for example, the extending direction of the control line and the first electrode electrically connected to the control line, the signal line and the second electrically connected to the signal line The extending directions of the electrodes intersect. At the intersection, the control line and the first electrode, and the signal line and the second electrode are separated by an insulator. Accordingly, a mutual capacitance is generated between the control line or the first electrode and the signal line or the second electrode in the vicinity of the intersection. Further, when the detected object is close to the control line, the first electrode, the signal line, or the second electrode, an electrostatic capacitance is generated between the detected object and them.

When an AC or pulse voltage is applied to the control line, a current flows through the signal line depending on the mutual capacitance of the intersection. However, if the sensing object comes close to the intersection and the capacitance is generated, the current is affected by the capacitance in addition to the mutual capacitance, so the value of the current flowing through the signal line is close to the sensing object. Changes compared to when not. Therefore, the current flowing through the signal line can be used as the detection signal. In addition, when a plurality of control lines and signal lines are provided, when a voltage is sequentially supplied to the plurality of control lines, a current sequentially flows through the plurality of signal lines. From the amount of change in the current flowing through the plurality of signal lines and the timing at which the current flows, it is possible to detect the position of the intersection where the detection target is close. Therefore, it is possible to detect the position of the detection object that is close to or in contact with the touch sensor 600.

"wiring"
The touch sensor 600 includes wiring. The wiring includes a control line CL (i), a signal line ML (j), and the like.

An alloy film combining elements or a stacked structure in which nitride films are stacked can be used.

Alternatively, a conductive oxide such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, or zinc oxide to which gallium is added can be used.

Alternatively, graphene or graphite can be used. The film containing graphene can be formed, for example, by reducing a film containing graphene oxide formed in a film shape. Examples of the reduction method include a method of applying heat and a method of using a reducing agent.

Alternatively, a conductive polymer can be used.

《Flexible substrate》
The flexible substrate 610 is not particularly limited as long as it has heat resistance enough to withstand the manufacturing process and a thickness and size applicable to a manufacturing apparatus. Note that a light-transmitting material is used for the flexible substrate 610 in the case where the touch sensor 600 is provided on the display side of the display portion 500.

An organic material, an inorganic material, or a composite material such as an organic material and an inorganic material can be used for the flexible substrate 610.

For example, an inorganic material such as a metal can be used for the flexible substrate 610.

For example, an organic material such as a resin, a resin film, or plastic can be used for the flexible substrate 610.

Specifically, a resin film or a resin plate such as polyester, polyolefin, polyamide, polyimide, polycarbonate, or an acrylic resin can be used for the flexible substrate 610.

The flexible printed circuit board FPC1 supplies a timing signal, a power supply potential, and the like, and is supplied with a detection signal (see FIG. 10).

<Display section>
The display unit 500 includes a pixel 502, a scan line, a signal line, or a flexible substrate 510.

Note that the display portion 500 may be formed by forming a film for forming the display portion 500 over the flexible substrate 510 and processing the film.

Alternatively, the display unit 500 may be formed by forming part of the display unit 500 on another base material and transferring the part to the flexible substrate 510.

<Pixel>
The pixel 502 includes a sub-pixel 502B, a sub-pixel 502G, and a sub-pixel 502R, and each sub-pixel includes a display element and a pixel circuit that drives the display element.

<Pixel circuit>
An active matrix method in which an active element is included in a pixel or a passive matrix method in which an active element is not included in a pixel can be used for the display portion.

In the active matrix system, not only transistors but also various active elements can be used as active elements (also referred to as active elements or nonlinear elements). For example, MIM (Metal Insulator Metal) or TFD (Thin Film Diode) can be used. Since these elements have few manufacturing steps, manufacturing cost can be reduced or yield can be improved. Alternatively, since these elements have small element sizes, the aperture ratio can be improved, and power consumption and luminance can be increased.

As a method other than the active matrix method, a passive matrix method that does not use active elements may be used. Since no active element is used, the number of manufacturing steps is small, and manufacturing costs can be reduced or yield can be improved. Alternatively, since an active element is not used, the aperture ratio can be improved, power consumption can be reduced, brightness can be increased, and the like.

The pixel circuit includes, for example, a transistor 502t (see FIG. 11A).

The display portion 500 includes an insulating film 521 that covers the transistor 502t. The insulating film 521 can be used as a layer for planarizing unevenness caused by the pixel circuit. Alternatively, the insulating film 521 can be a stacked film including a layer that can suppress diffusion of impurities. Accordingly, a decrease in reliability of the transistor 502t and the like due to impurity diffusion can be suppressed.

<Display element>
Various display elements can be used for the display portion 500. For example, a display element (also referred to as electronic ink) that performs display by an electrophoresis method, an electro-powder fluid (registered trademark) method, an electrowetting method, a shutter-type MEMS display device, an optical interference-type MEMS display device, a liquid crystal device Etc. can be used.

In addition, a display element that can be used for a transmissive liquid crystal display, a transflective liquid crystal display, a reflective liquid crystal display, a direct-view liquid crystal display, or the like can be used.

For example, you may apply the organic electroluminescent element from which the color of the emitted light differs for every subpixel.

For example, an organic electroluminescence element that emits white light can be applied.

For example, the light-emitting element 550R includes a lower electrode, an upper electrode, and a layer containing a light-emitting organic compound between the lower electrode and the upper electrode.

The subpixel 502R includes a light emitting module 580R. The sub-pixel 502R includes a pixel circuit including a light-emitting element 550R and a transistor 502t that can supply power to the light-emitting element 550R. The light emitting module 580R includes a light emitting element 550R and an optical element (for example, a colored layer CFR).

Note that a microresonator structure can be provided in the light emitting module 580R so that light of a specific wavelength can be extracted efficiently. Specifically, a layer containing a light-emitting organic compound may be disposed between a film that reflects visible light and a semi-reflective / semi-transmissive film that is arranged so that specific light can be efficiently extracted.

The light emitting module 580R has a colored layer CFR in the direction of extracting light. The colored layer only needs to transmit light having a specific wavelength. For example, a colored layer CFR that selectively transmits red light, a colored layer CFG that selectively transmits green light, and blue light are selected. For example, a colored layer CFB that transmits light or a colored layer that selectively transmits light such as yellow can be used. Note that another sub-pixel may be arranged so as to overlap with a window portion where the colored layer is not provided, and light emitted from the light-emitting element may be emitted without passing through the colored layer.

The colored layer CFR is in a position overlapping the light emitting element 550R. Thus, part of the light emitted from the light emitting element 550R passes through the colored layer CFR and is emitted to the outside of the light emitting module 580R in the direction of the arrow shown in the drawing.

There is a light-shielding layer BM so as to surround the colored layer (for example, the colored layer CFR).

Note that in the case where the sealing material 560 is provided on the light extraction side, the sealing material 560 may be in contact with the light-emitting element 550R and the coloring layer CFR.

The lower electrode is disposed on the insulating film 521. A partition wall 528 provided with an opening overlapping the lower electrode is provided. Note that a part of the partition wall 528 overlaps with an end portion of the lower electrode.

A light emitting element (for example, light emitting element 550R) is configured by sandwiching a layer containing a light emitting organic compound between the lower electrode and the upper electrode. The pixel circuit supplies power to the light emitting element.

In addition, a spacer for controlling the distance between the flexible substrate 610 and the flexible substrate 510 is provided over the partition wall 528.

Note that in the case of realizing a transflective liquid crystal display or a reflective liquid crystal display, part or all of the pixel electrode may have a function as a reflective electrode. For example, part or all of the pixel electrode may have aluminum, silver, or the like.

Further, a memory circuit such as an SRAM can be provided under the reflective electrode. Thereby, power consumption can be further reduced. In addition, a structure suitable for a display element to be applied can be selected from various pixel circuits and used.

《Flexible substrate》
For example, a material similar to a material that can be used for the flexible substrate 610 can be applied to the flexible substrate 510.

Note that in the case where the flexible substrate 510 does not require light-transmitting properties, for example, a colored material, a material that does not transmit light, specifically, a yellow-colored resin, SUS, aluminum, or the like is used. it can.

For example, the flexible substrate 510 is preferably a stacked body in which a flexible substrate 510b, a barrier film 510a that prevents diffusion of impurities, and a resin layer 510c that bonds the substrate 510b and the barrier film 510a are stacked. It can be used (see FIG. 11A).

<Encapsulant>
The sealing material 560 bonds the flexible substrate 610 and the flexible substrate 510 together. The encapsulant 560 has a higher refractive index than air.

Note that the pixel circuit or the light-emitting element (eg, the light-emitting element 550R) is between the flexible substrate 510 and the flexible substrate 610.

<Drive circuit configuration>
The drive circuit 503g supplies a selection signal. For example, a selection signal is supplied to the scanning line (see FIG. 10).

Further, a drive circuit 503s that supplies an image signal may be provided. For example, the transistor 503t or the capacitor 503c can be used for the driver circuit 503s.

For example, a sequential circuit such as a shift register or a flip-flop circuit, a combination circuit, or the like can be used for the driver circuit 503g or the driver circuit 503s.

Note that a transistor which can be formed over the same substrate in the same process as the pixel circuit can be used for the driver circuit.

"wiring"
The display unit 500 includes wiring such as scanning lines, signal lines, and power supply lines. Various conductive films can be used. For example, a material similar to that of the conductive film that can be used for the touch sensor 600 can be used.

The display portion 500 includes a wiring 511 that can supply a signal, and a terminal 519 is provided in the wiring 511. Note that a flexible printed circuit board FPC2 that can supply signals such as an image signal and a synchronization signal is electrically connected to the terminal 519.

Note that a printed wiring board (PWB) may be attached to the flexible printed circuit board FPC2.

<Other configuration>
The touch panel 500TP includes an antireflection layer 670p at a position overlapping the pixel. For example, a circularly polarizing plate can be used as the antireflection layer 670p.

<Modified example of touch panel>

For example, a semiconductor layer including a single crystal silicon film or the like transferred from a polycrystalline silicon, a single crystal silicon substrate, or the like can be applied to the transistor 502t and the transistor 503t illustrated in FIG.

For example, a dual-gate transistor including gate electrodes above and below the semiconductor layer can be used as the transistor 502t and the transistor 503t.

In addition, the transistor 502t and the transistor 503t are preferably transistors in which a gate electrode surrounds a semiconductor layer. As the transistor having the above structure, for example, there is a Fin type transistor.

Note that this embodiment can be combined with any of the other embodiments described in this specification as appropriate.

(Embodiment 3)
In this embodiment, a structure of the touch sensor 600 provided in the touch panel 500TP and a method of driving the touch sensor based on the first information or the second information related to the state of the touch panel 500TP are described with reference to FIGS. Will be described with reference to FIG.

There are the following two configurations for connecting the end of the touch panel 500TP and the winding unit 106. One is a configuration in which a direction in which a control line provided in the touch sensor 600 extends and a direction in which the touch panel 500TP is wound up by the winding unit 106 intersect. The other is a configuration in which a direction in which signal lines provided in the touch sensor 600 extend and a direction in which the touch panel 500TP is wound up by the winding unit 106 intersect. The above two configurations differ in the method for driving a part of the touch sensor 600. In this embodiment, a method for driving a part of the touch sensor 600 will be described with respect to the above two configurations. Two other configuration examples will also be described.

<Configuration Example 1 of Touch Sensor>

FIG. 12A illustrates a top view and a block diagram of the touch sensor 600 of Configuration Example 1. FIG. 12A illustrates a state in which the touch sensor 600 is expanded in a planar shape for the sake of explanation, a part of the touch panel 500TP is wound around the winding unit 106 using FIG. 12A. The driving method in the taken state may be described.

The drive unit 103 includes a control unit 103C and an output unit 103D. The control unit 103C supplies a control signal to the touch sensor 600. The output unit 103D is supplied with a detection signal. The detection signal includes information related to the position of the touch sensor with which a detection target such as a finger or a stylus pen comes close to or touches.

The touch sensor 600 includes control lines CL (1) to CL (m), signal lines ML (1) to ML (n), and a flexible substrate 610 (FIG. 12A). reference). Note that n and m are natural numbers of 2 or more.

The control line is supplied with a control signal and extends in a direction indicated by an arrow R in the drawing.

The signal line extends in a direction indicated by an arrow C in the drawing and supplies a detection signal.

The flexible substrate 610 supports control lines and signal lines.

The control lines CL (1) to CL (m) are electrically connected to the control unit 103C through the wiring unit 111 and the flexible substrate FPC1 formed of a plurality of wirings. In addition, the signal lines ML (1) to ML (n) are electrically connected to the output unit 103D through the wiring unit 112 including a plurality of wirings and the flexible substrate FPC1. In FIG. 12A, the wiring portion 111 is provided along one side of the touch sensor 600, but in addition to this, the wiring portion 111 may be provided on the opposite side.

The touch panel 500TP and the winding unit 106 are fixed in the direction of the side of the area 107 of the touch sensor. For example, when the edge of the touch panel 500TP and the edge of the touch sensor 600 are aligned and the area 107 is the same as the edge of the touch panel 500TP, the touch panel 500TP is fixed to the winding unit 106 in the area 107. Even when the end of the touch panel 500TP does not coincide with the end of the touch sensor 600, the touch panel 500TP is fixed to the winding unit 106 in the region 107_2 outside the region 107 as shown in FIG. Therefore, the direction in which the touch panel 500TP is wound around the winding unit 106 is the direction indicated by the arrow C.

In this configuration example, the direction in which the touch panel 500TP is wound around the winding unit 106 intersects the direction in which the control line extends.

In addition, the direction in which the touch panel 500TP is wound around the winding unit 106 preferably intersects the direction in which the control line extends perpendicularly. By setting it as the said structure, it becomes difficult to be in the state by which a control line is partially provided in the area | region wound by the winding part 106 of the touchscreen 500TP. This is because, in the above configuration, the boundary line between the wound area and the unrolled area is parallel to the control line.

The touch sensor 600 of one embodiment of the present invention includes the first electrode C1 (1) to the first electrode C1 (m), the second electrode C2 (1) to the second electrode C2 (n), and the like. .

The first electrode C1 (i) is electrically connected to one control line CL (i). Note that i is a natural number of 1 to m.

The second electrode C2 (j) includes a portion that is electrically connected to one signal line ML (j) and does not overlap with the first electrode C1 (1) to the first electrode C1 (m). J is a natural number between 1 and n.

The flexible substrate 610 supports the first electrode and the second electrode.

The control lines CL (1) to CL (m) can be supplied with a control signal. Note that the control lines CL (1) to CL (m) may have a function of supplying and supplying a modulated control signal.

The signal lines ML (1) to ML (n) can be supplied with detection signals.

A control signal supplied from the control line is detected by the signal line through a capacitor formed between the signal line and the control line, and becomes a detection signal.

In the case where the signal line and the control line are formed using the conductive film formed in the same process, one wiring is formed separately at the intersection of the control line and the signal line. Then, an insulating film is provided at the intersection, and one wiring separated using another conductive film sandwiching the insulating film between the other wiring is electrically connected.

For example, the control line CL (i) is formed separately, and the separated control line CL (i) is electrically connected using the conductive film BR (i, j). Note that an insulating film 611 is provided at an intersection of the conductive film BR (i, j) and the signal line ML (j) (see FIG. 14A).

Further, a light shielding layer BM may be provided between the signal line ML (j) and the flexible substrate 610 and between the control line CL (i) and the flexible substrate 610. The light shielding layer BM can weaken the intensity of light incident on the signal line or the control line from the flexible substrate 610 side or the intensity of light reflected by the signal line ML (j) or the control line CL (i). . Note that the light-blocking layer BM can include an opening (see FIG. 14C).

The insulating film 611 has an opening reaching the control line CL (i), and the control line CL (i) is electrically connected to the conductive film BR (i, j) in the opening.

Specifically, the control line CL (i) and the signal line ML (j) are formed of a conductive film formed in the same process, and the control line CL (i) intersects the signal line ML (j). Separated. The separated control line CL (i) is electrically connected by the conductive film BR (i, j).

In addition, a first electrode C1 (i) electrically connected to the control line CL (i) can be provided. The first electrode C <b> 1 (i) can easily detect a detection object such as a finger or a stylus pen that is close to or in contact with the touch sensor 600.

In addition, a second electrode C2 (j) electrically connected to the signal line ML (j) can be provided. The second electrode C <b> 2 (j) can easily detect a detection target such as a finger or a stylus pen that is close to or in contact with the touch sensor 600.

For example, rectangular electrodes can be used for the first electrode C1 (i) and the second electrode C2 (j) (see FIG. 14A). Note that when a light-transmitting conductive film is used, a light-transmitting touch sensor can be provided.

For example, a rectangular first electrode C1 (i) and second electrode C2 (j) each having an opening so as to have a mesh shape can be used (FIG. 14B or FIG. C)). Note that when a metal film or the like provided with an opening is used, electric resistance can be reduced as compared to the case of using a light-transmitting conductive film. Thereby, touch sensors of various sizes having translucency can be provided, and detection information can be supplied without depending on the size. For example, touch sensors of various sizes can be provided from a size that can be used for a handheld type to a size that can be used for an electronic blackboard.

<< First electrode C1 (i), second electrode C2 (j) and conductive film BR (i, j) >>
Various conductive materials can be used for the wiring, the first electrode C1 (i), the second electrode C2 (j), and the conductive film BR (i, j).

For example, an inorganic conductive material, an organic conductive material, a metal, conductive ceramics, or the like can be used for the conductive film.

Specifically, a metal element selected from aluminum, gold, platinum, silver, chromium, tantalum, titanium, molybdenum, tungsten, nickel, iron, cobalt, yttrium, zirconium, palladium, or manganese, and an alloy containing the above metal elements Alternatively, an alloy or the like in which the above metal elements are combined can be used for the wiring or the like. In particular, it is preferable that one or more elements selected from aluminum, chromium, copper, tantalum, titanium, molybdenum, and tungsten are included. In particular, an alloy of copper and manganese is suitable for fine processing using a wet etching method.

Specifically, a two-layer structure in which a titanium film is laminated on an aluminum film, a two-layer structure in which a titanium film is laminated on a titanium nitride film, a two-layer structure in which a tungsten film is laminated on a titanium nitride film, a tantalum nitride film or A two-layer structure in which a tungsten film is stacked over a tungsten nitride film, a titanium film, and a three-layer structure in which an aluminum film is stacked over the titanium film and a titanium film is further formed thereon can be used.

Specifically, a film of an element selected from titanium, tantalum, tungsten, molybdenum, chromium, neodymium, and scandium on the aluminum film, or a plurality of elements selected from titanium, tantalum, tungsten, molybdenum, chromium, neodymium, or scandium. An alloy film combining elements or a stacked structure in which nitride films are stacked can be used.

Alternatively, a conductive oxide such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, or zinc oxide to which gallium is added can be used for the conductive film.

Alternatively, graphene or graphite can be used for the conductive film. The film containing graphene can be formed, for example, by reducing a film containing graphene oxide formed in a film shape. Examples of the reduction method include a method of applying heat and a method of using a reducing agent.

Alternatively, a conductive polymer can be used for the conductive film.

<< Driving Method of Touch Sensor in Configuration Example 1 >>
Hereinafter, a method in which the driving unit 103 drives a part of the touch sensor 600 in the touch panel 500TP of the configuration example 1 will be described. Specifically, when the touch panel 500TP is partially wound around the winding unit 106, the touch sensor 600 provided in an area that is not wound around the winding unit of the touch panel 500TP is driven to wind the touch panel 500TP. A method of not driving the touch sensor 600 provided in the region wound around the part will be described with reference to FIG.

From the detection unit 104, first information related to the state of the touch panel 500TP is supplied to the drive unit. Specifically, the detection unit 104 supplies the first information related to the region wound around the winding unit 106 of the touch panel 500TP to the driving unit 103.

As shown in FIG. 15A, the detection unit 104 supplies the first information related to the state of the touch panel 500TP to the calculation unit 110, and the calculation unit 110 determines the touch panel 500TP based on the first information. It is good also as a structure which calculates the 2nd information which concerns on a state. The second information related to the state of the touch panel 500TP calculated by the calculation unit 110 is supplied to the driving unit 103. Specifically, the detection unit 104 supplies first information related to the area wound around the winding unit 106 of the touch panel 500TP to the calculation unit 110, and the calculation unit 110 is based on the first information. The second information relating to the area wound up by the 500 TP winding unit 106 is calculated. The second information related to the region wound around the winding unit 106 of the touch panel 500TP calculated by the calculation unit 110 is supplied to the driving unit 103.

The control unit 103C of the drive unit 103 supplies a control signal. For example, the control unit 103C supplies the control signal for each control line in turn. Alternatively, a plurality of signals modulated by a method that can be separated by the output unit 103D are supplied to a plurality of control lines at the same time.

However, based on the first information or the second information of the region wound around the winding unit 106 of the touch panel 500TP supplied to the driving unit 103, the region that is not wound around the winding unit 106 of the touch panel 500TP A control signal is supplied to the provided control line, and no control signal is supplied to the control line provided in the area wound around the winding unit 106 of the touch panel 500TP. For example, when the control lines CL (1) to CL (k1) are provided in the region wound around the winding unit 106 of the touch panel 500TP, control signals are sent to the control lines CL (k1 + 1) to CL (m). The control signal is not supplied to the control lines CL (1) to CL (k1). Here, k1 is a natural number between 1 and m-1. Note that even if a part of the control line is provided in an area wound around the winding unit 106 of the touch panel 500TP, no control signal is supplied to the control line. Further, it is not necessary to supply control signals to all of the control lines CL (k1 + 1) to CL (m), and selection can be made as necessary. Specifically, for example, when the roller 108 or the like is in contact with the control line CL (i), the control signal need not be supplied to the control line CL (i).

When a detected object such as a finger or a stylus pen comes close to a conductive film such as the first electrode C1 (i1) electrically connected to the control line CL (i1) or the control line CL (i1), the detected object And the capacitance between the conductive film changes. Here, i1 is a natural number of (k1 + 1) to m. In addition, the detected object and the conductive property of the detected object come close to the conductive film such as the second electrode C2 (j) electrically connected to the signal line ML (j) and the signal line ML (j). The capacitance between the films also changes. Then, the detection signal changes based on the change in the capacitance.

The output unit 103D is supplied with a detection signal. The detection signal changes as the detection object approaches the first electrode and the second electrode. The touch sensor 600 can know the proximity or contact of the detection target based on, for example, whether the change in the detection signal exceeds a threshold value. The above operation can be rephrased as touch detection.

By using the driving method described above, erroneous detection of the touch sensor 600 included in the information processing apparatus 100 can be prevented. In addition, since the number of control lines for supplying control signals can be reduced, power consumption can be reduced.

<Modification of Configuration Example 1 of Touch Sensor>
The detection signal passes through the signal line and the second electrode and is supplied to the output unit. In the configuration of FIG. 12A, the touch panel 500TP is wound up from the side closer to the output unit, and thus the detection signal is transmitted to the signal line provided in the region wound up by the winding unit 106 of the touch panel 500TP and Through two electrodes.

On the other hand, the touch sensor 600 may have a configuration in which the wiring portion 112 is drawn as illustrated in FIG. As a result, the detection signal is supplied to the output unit 103D without passing through the second electrode provided in the region wound around the winding unit 106 of the touch panel 500TP.

Further, as shown in FIG. 17A, the driving unit 103 may be provided in a direction different from the direction in which the winding unit 106 is provided. Accordingly, the detection signal is supplied to the output unit 103D without passing through the signal line and the second electrode provided in the region wound around the winding unit 106 of the touch panel 500TP. In the structure of FIG. 17A, for example, the driving unit can be provided in a handle.

<Configuration example 2 of touch sensor>
The configuration example 2 is different from the configuration example 1 in the positional relationship between the control line, the signal line, and the winding unit 106. Configuration Example 2 will be described with reference to FIG.

FIG. 12B illustrates a top view and a block diagram of the touch sensor 600 of Configuration Example 2. 12B illustrates a state in which the touch sensor 600 is expanded in a planar shape for the sake of explanation, a part of the touch panel 500TP is wound around the winding unit 106 using FIG. 12B. The driving method in the taken state may be described.

The drive unit 103 includes a control unit 103C and an output unit 103D. The control unit 103C supplies a control signal. The output unit 103D is supplied with a detection signal. The detection signal includes information related to the position of the touch sensor with which a detection target such as a finger or a stylus pen comes close to or touches.

The control line is supplied with a control signal and extends in a direction indicated by an arrow C in the drawing.

The signal line extends in a direction indicated by an arrow R in the drawing and supplies a detection signal.

The flexible substrate 610 supports control lines and signal lines.

The control lines CL (1) to CL (m) are electrically connected to the control unit 103C through the wiring unit 111 and the flexible substrate FPC1 formed of a plurality of wirings. In addition, the signal lines ML (1) to ML (n) are electrically connected to the output unit 103D through the wiring unit 112 including a plurality of wirings and the flexible substrate FPC1. In FIG. 12B, the wiring portion 112 is provided along one side of the touch sensor 600, but in addition to this, the wiring portion 112 may be provided on the opposite side.

The touch panel 500TP and the winding unit 106 are fixed in the direction of the side of the area 107 of the touch sensor. For example, if the end of the touch panel 500TP and the end of the touch sensor 600 coincide with each other and the area 107 becomes the end of the touch panel 500TP, the touch panel 500TP is fixed to the winding unit 106 in the area 107. Even when the edge of the touch panel 500TP does not coincide with the edge of the touch sensor 600, the touch panel 500TP is fixed to the winding unit 106 in the area 107_2 outside the area 107 as shown in FIG. Therefore, the direction in which the touch panel 500TP is wound around the winding unit 106 is the direction indicated by the arrow C.

In this configuration example, the direction in which the touch panel 500TP is wound around the winding unit 106 intersects with the direction in which the signal line extends.

Further, it is preferable that the direction in which the touch panel 500TP is wound around the winding unit 106 intersects the signal line extending direction perpendicularly. By adopting the above configuration, a part of the signal line exists in a region wound around the winding unit 106, and another part of the signal line exists in a region not wound around the winding unit 106. It becomes difficult to become the state of doing.

<< Driving Method of Touch Sensor in Configuration Example 2 >>
Hereinafter, a method in which the drive unit 103 drives a part of the touch sensor 600 in the touch panel 500TP of the configuration example 2 will be described. Specifically, when the touch panel 500TP is partially wound around the winding unit 106, the touch sensor 600 provided in an area that is not wound around the winding unit of the touch panel 500TP is driven to wind the touch panel 500TP. A method of not driving the touch sensor 600 provided in the region wound around the part will be described with reference to FIG.

From the detection unit 104, first information related to the state of the touch panel 500TP is supplied to the drive unit 103. Specifically, the detection unit 104 supplies the first information related to the region wound around the winding unit 106 of the touch panel 500TP to the driving unit 103.

Note that, as illustrated in FIG. 15B, the detection unit 104 supplies the first information related to the state of the touch panel 500TP to the calculation unit 110, and the calculation unit 110 determines the touch panel 500TP based on the first information. It is good also as a structure which calculates the 2nd information which concerns on a state. The second information related to the state of the touch panel 500TP calculated by the calculation unit 110 is supplied to the driving unit 103. Specifically, the detection unit 104 supplies first information related to the area wound around the winding unit 106 of the touch panel 500TP to the calculation unit 110, and the calculation unit 110 is based on the first information. The second information relating to the area wound up by the 500 TP winding unit 106 is calculated. The second information related to the region wound around the winding unit 106 of the touch panel 500TP calculated by the calculation unit 110 is supplied to the driving unit 103.

The control unit 103C of the driving unit 103 supplies a control signal to the control lines CL (1) to CL (m). For example, the control unit 103C sequentially supplies the control signal for each control line CL (i). Alternatively, a plurality of signals modulated by a method that can be separated by the output unit 103D are supplied to the plurality of control lines CL (i) at the same time.

When a detected object such as a finger or a stylus pen comes close to a conductive film such as the first electrode C1 (i) electrically connected to the control line CL (i) or the control line CL (i), the detected object And the capacitance between the conductive film changes. In addition, the detected object and the conductive property of the detected object come close to the conductive film such as the second electrode C2 (j) electrically connected to the signal line ML (j) and the signal line ML (j). The capacitance between the films also changes. Then, the detection signal changes based on the change in the capacitance.

The output unit 103D is supplied with a detection signal. The detection signal changes as the detection object approaches the first electrode and the second electrode. The output unit 103D can detect the proximity of the detection target to the conductive film based on, for example, whether the change in the detection signal exceeds a threshold value. Further, the touch sensor 600 can know the position on the touch sensor 600 where the detection target is close or in contact.

However, the signal line ML provided in the region not wound around the winding unit 106 of the touch panel 500TP based on the first information related to the region wound around the winding unit of the touch panel 500TP supplied from the detection unit. The detection information supplied from (j) is used, and the detection information supplied from the signal line ML (j) provided in the area wound around the winding unit 106 of the touch panel 500TP is not used. For example, when the signal lines ML (1) to ML (k2) are provided in the region wound around the winding unit 106 of the touch panel 500TP, the detection supplied from the signal lines ML (k2 + 1) to ML (n) Information is used, and detection information supplied from the signal lines ML (1) to ML (k2) is not used. Here, k2 is a natural number between 1 and n-1. Note that it is not necessary to use all detection information supplied from the signal lines ML (k2 + 1) to ML (n), and selection can be made as necessary. Specifically, for example, when the roller 108 or the like is in contact with the signal line ML (k2 + 1), the detection information of the signal line ML (k2 + 1) may not be used.

By using the driving method described above, erroneous detection of the touch sensor 600 included in the information processing apparatus 100 can be prevented.

<Modification of Configuration Example 2 of Touch Sensor>

A part of the film can be peeled off, and the part can be selectively excised.

Further, a layer capable of suppressing the adhesion force of the bonding layer 30 to the first layer to be peeled F3 may be selectively formed on a part of the first layer to be peeled F3. For example, a material that is difficult to adhere to the bonding layer 30 may be selectively formed. Specifically, the organic material may be deposited in an island shape. As a result, a part of the bonding layer 30 can be easily selectively removed together with the second layer to be peeled S3. As a result, the first layer to be peeled F3 can be exposed.

For example, when the first layer to be peeled F3 includes a functional layer and a conductive layer F3b electrically connected to the functional layer, the conductive layer F3b is exposed to the opening of the second stacked body 92c. be able to. Thereby, for example, the conductive layer F3b exposed in the opening can be used as a terminal to which a signal is supplied.

Alternatively, a signal to which a functional layer is supplied can be used for a terminal to which an external device can supply.

<< Example 2 of Manufacturing Method of Laminate Having Opening on Support >>
A mask 48 having an opening provided so as to overlap with the opening provided in the second support 42 is formed in the stacked body 92. Next, the solvent 49 is dropped into the opening of the mask 48. Thus, the second support 42 exposed to the opening of the mask 48 can be swollen or dissolved using the solvent 49 (see FIGS. 21C-1 and 21C-2).

After the excess solvent 49 is removed, stress is applied by rubbing the second support 42 exposed in the opening of the mask 48. Thereby, the second support 42 and the like that overlap the opening of the mask 48 can be removed.

In addition, when a solvent that swells or dissolves the bonding layer 30 is used, the first peelable layer F3 can be exposed (see FIGS. 21D-1 and 21D-2).

The boundary where the first peelable layer F3 can be separated from the first substrate may be formed between the first peelable layer F3 and the first peelable layer F2, and the first peelable layer F2 And the first substrate F1.

In the case where a boundary is formed between the first peelable layer F3 and the first peelable layer F2, the first peelable layer F2 is not included in the stacked body, and the first peelable layer F2 and the first substrate F1. In the case where a boundary is formed between the first release layers F2, the first release layer F2 is included in the laminate.

A film including a stacked material in which a silicon oxynitride film having a thickness of 600 nm and a silicon nitride having a thickness of 200 nm are stacked in this order from the first peeling layer F2 side can be used for the first peeling layer F3. Note that the silicon oxynitride film has a higher oxygen composition than the nitrogen composition, and the silicon nitride oxide film has a higher nitrogen composition than the oxygen composition.

Specifically, instead of the first layer to be peeled F3, a silicon oxynitride film with a thickness of 600 nm, a silicon nitride with a thickness of 200 nm, and a silicon oxynitride with a thickness of 200 nm are sequentially formed from the first peeling layer F2 side.

<2. Configuration Example 2 of Processing Member>
A structure of a processed member different from the above, which can be a laminated body, will be described with reference to FIGS. 22B-1 and 22B-2.

The processed member 90 is different from the processed member 80 in that the other surface of the bonding layer 30 is in contact with one surface of the second layer to be peeled S3 instead of the substrate S5.

And a bonding layer 30 in contact with one surface of the second layer to be peeled S3 and the other surface. (See FIG. 22B-1 and FIG. 22B-2).

Note that the processed member having such a structure can be a stacked body that can be used as a flexible display device.

Note that this embodiment can be combined with any of the other embodiments described in this specification as appropriate.

In this example, a foldable touch panel of one embodiment of the present invention was manufactured. Moreover, a present Example demonstrates the result of having performed the sensing test in the state bent with respect to the said touch panel.

[Production of touch panel]
In this example, an in-cell type touch panel in which a touch sensor is formed on a counter substrate (a substrate on the display surface side) of a flexible display panel was manufactured. Furthermore, the electrode of the touch sensor has a mesh shape (also referred to as a metal mesh shape), thereby reducing the load capacity between the touch sensor and the display panel. With such a configuration, the thickness of the entire touch panel can be reduced to such an extent that the user can freely fold it. In addition, since the load capacity is small, the influence of noise from the display panel to the touch sensor is suppressed, and it is possible to suppress the occurrence of problems such as false detection and detection failure.

  As a driving method of the in-cell type touch panel manufactured in this example, a mutual capacitance method, which is one of the projected capacitance methods, was adopted.

FIG. 23A illustrates a structure of the touch panel manufactured in this example. 23A shows a schematic diagram of the touch panel at the center, a cross-sectional structure of the touch panel on the left side, and an enlarged view of a bent part of the touch panel on the right side. The touch panel includes a flexible display portion (displayed as Display) and an FPC. The touch panel has a configuration in which two flexible substrates are bonded together with an adhesive layer. A passivation layer is provided on each of the opposing surfaces of the flexible substrate. On one flexible substrate, an FET layer and an organic EL element (denoted as OLED) are formed on the passivation layer. On the other flexible substrate, a touch sensor and a color filter are formed on the passivation layer. As shown in FIG. 23A, the touch panel manufactured in this embodiment can be bent so that the display surface has a convex shape and can be bent to have a concave shape.

FIG. 23B shows a more specific cross-sectional structure. On one flexible substrate side, both ends of the organic EL element have partition walls (indicated as “Partition”), and spacers are provided on the partition walls. On the surface of the other flexible substrate on the organic EL element side, a black matrix, a sensor electrode (sensor metal) constituting a touch sensor, a bridge electrode (Bridge metal), and a color filter are sequentially formed on the passivation layer. Has been. The color filter is disposed so as to overlap with the organic EL element. Between each of the black matrix, the sensor electrode, the bridge electrode, and the color filter, an insulating layer (indicated as “Inter layer”) is provided. Each of the sensor electrode and the bridge electrode is arranged so as to overlap the black matrix. By disposing the black matrix closer to the display surface than the sensor electrode and the bridge electrode, reflection of external light by these can be suppressed. Furthermore, by arranging the sensor electrode and the bridge electrode inside the width of the black matrix, the influence on the aperture ratio (light extraction efficiency) can be minimized.

For the production of the touch panel, first, a release layer, a passivation layer, an FET layer, and an organic EL element were formed on a glass substrate.

As a transistor included in the FET layer (corresponding to the transistor 502t), a transistor using an oxide semiconductor as a semiconductor in which a channel is formed was used. Here, in this example, the oxide semiconductor is a crystalline oxide semiconductor (CAAC-OS: C-Axis) in which the c-axis is oriented in a direction substantially perpendicular to the film surface and a crystal grain boundary in the film surface direction is not confirmed. Aligned Crystalline-Oxide Semiconductor) was used.

A CAAC-OS is a crystalline oxide semiconductor in which the c-axis of crystals is approximately perpendicular to the film surface. Since the CAAC-OS has a feature that a crystal grain boundary is not confirmed, a stable and uniform film can be formed over a large area, and the CAAC-OS can be formed by stress generated when a flexible light-emitting device is bent. Cracks are unlikely to occur in the OS film.

In this example, an In—Ga—Zn-based oxide was used as the oxide semiconductor material.

As the pixel electrode (lower electrode), an alloy containing silver having a very high reflectance was used. In addition, a transparent electrode layer (also referred to as an optical adjustment layer) with an appropriate thickness was formed on the pixel electrode so as to obtain a microcavity effect according to the configuration of the subpixel.

As the organic EL element, a top emission type white EL element was used. The organic EL element has a tandem structure in which a blue light emitting unit and a yellow light emitting unit are stacked.

In addition, a peeling layer, a passivation layer, a black matrix, a sensor electrode, a bridge electrode, a color filter, and an insulating layer between them were formed on a glass substrate different from the above.

Subsequently, the two substrates were bonded together with an adhesive layer. The distance between the substrates (cell gap) at this time was adjusted to about 5 μm. Then, each board | substrate was peeled between the peeling layer and the passivation layer, and the flexible substrate was affixed. A plastic substrate having a thickness of about 20 μm was used as the flexible substrate.

The touch panel was produced as described above. The specification of the touch panel is that the size of the display portion is 8.67 inches diagonal, the number of pixels is 1080 × RGBY × 1920, the definition is 254 ppi, and the aperture ratio is about 46%. The touch sensor used mesh-shaped sensor electrodes, and formed 48 transmission electrodes in the long side direction of the display portion and 27 reception electrodes in the short side direction. Each interval was set to 4 mm. In the touch sensor, a region of 40 × 40 pixels included in the display unit corresponds to one unit of the touch sensor.

It was confirmed that the produced touch panel can be normally displayed both when the display surface is bent into a convex shape from a flat state and when it is bent into a concave shape. Furthermore, it was confirmed that the surface of the touch panel can be normally detected in each of a flat part, a convex part, and a concave part.

[Evaluation of parasitic resistance / parasitic capacitance at the bending part]
The effect of bending the produced touch panel on the parasitic capacitance and parasitic resistance between the receiving electrode and the display panel was evaluated.

The measurement was performed in three ways: a state where the display surface of the touch panel was flat, a state bent into a convex shape, and a state bent into a concave shape. Moreover, when the curvature radius R was 10 mm, it investigated about 2 types, when it was 5 mm.

The measurement was performed using an LCR meter (Agilent Technology Co., Ltd., 4275A).

FIG. 24 shows the rate of change in parasitic resistance and parasitic capacitance in the bent state when the state where the display surface is flat is used as a reference. The number of measurements is six. As shown in FIG. 24, the display surface was bent into a convex shape (expressed as outside bend) or bent into a concave shape (expressed as inside bend), and the radius of curvature was 5 mm. However, it was confirmed that the fluctuation rate of the parasitic resistance and the parasitic capacitance was as small as less than 0.1%. From this result, it was confirmed that the influence on the detection sensitivity by bending the touch panel was extremely small.

Below, the result of having investigated the influence on light extraction efficiency by providing the electrode of a touch sensor is demonstrated.

Since the touch panel manufactured in Example 1 uses a top emission type light emitting element, light from the light emitting element is extracted through the substrate on the opposite side. Therefore, both a flexible substrate on which the touch sensor electrode was formed and a flexible substrate on which the touch sensor electrode was not formed were produced, and the light transmittance was measured.

25A, 25B, and 25C show a schematic cross-sectional view of a measurement method and a manufactured sample.

FIG. 25A corresponds to a measurement system that directly measures the luminance of light from a reference light source. FIG. 25B corresponds to a measurement system that measures a sample (denoted as w / metal mesh) on which a mesh-shaped sensor electrode is formed. FIG. 25C corresponds to a measurement system that measures a sample (noted as w / o metal mesh) that does not form a mesh-like sensor electrode or the like as a comparison.

The sample shown in FIG. 25B is the same as the sample shown in FIG. 23B except that the layered structure above the color filter is different from the position of the flexible substrate. In FIG. 25B, the flexible substrate is attached to the color filter side through an adhesive layer.

The sample shown in FIG. 25C has a structure in which a black matrix and a color filter are formed over a passivation layer, and this is attached to a flexible substrate through an adhesive layer.

In the measurement, a sample was placed on a surface light source, and the luminance of light transmitted upward through the sample was measured with a measuring instrument. The number of measurements is twelve. An edge type backlight (MEBL-CW145 manufactured by Schott Moritex Co., Ltd.) was used as the surface light source. A color luminance meter (BM-5AS manufactured by Topcon Techno House Co., Ltd.) was used as the measuring instrument.

When each sample was placed on a surface light source and compared, the difference could not be confirmed visually. FIG. 26 shows the measurement results. In FIG. 26, when the sample is not arranged (FIG. 25A) is 100%, the luminance measured for each sample is shown as the transmittance. The transmittance of the sample on which the mesh-shaped sensor electrode was formed was about 16.0%, and the transmittance of the sample on which the sensor electrode was not formed was about 16.3%, confirming that there was almost no difference. The reason why the transmittance of the sample in which the mesh-shaped sensor electrode is formed is considered to be due to the difference in the laminated structure.

As described above, it was confirmed that the touch sensor of one embodiment of the present invention hardly affects the light extraction efficiency.
