JP4755835B2 - Compound display unit - Google Patents

Description

  The present invention relates to a composite display unit, and more particularly to a display unit in which a plurality of information input / output means are integrated.

  Along with the development of the information society, various information that has been distributed in newspapers and books in the past has become electronic information that is distributed to various terminals such as computers or PDAs. In response to this, research and development of various displays has become active.

  These displays are classified into a self-luminous display that emits light by itself and a reflective display that can be visually recognized by outside light such as room light and sunlight.

  A typical example of the former is a CRT display, but in recent years, it has been replaced by a thin display such as a liquid crystal display or a plasma display having a backlight, and an electron emission display (for example, see Patent Document 1). I am trying to do.

  Furthermore, recently, as a technology that can be expected to reduce the thickness and weight and reduce the cost of mass production, and can easily solve the low contrast and narrow viewing angle, which are disadvantages of liquid crystal displays, organic electroluminescence (EL) ) So-called organic EL displays using elements have attracted attention, and material research has been active (for example, see Patent Document 2).

  On the other hand, although there are technical issues such as narrow viewing angle, reflective liquid crystal displays that consume less energy than self-luminous displays are attractive to be discarded as displays for mobile terminals, and continue to improve brightness. Improvement research has been conducted (for example, see Patent Document 3).

  In addition, research on reflective displays using electrophoresis of so-called microcapsule particles has also become active (see, for example, Patent Document 4).

  In addition to these, various displays such as dispersed particle orientation display, colored particle rotation display, PLZT display, DMD (digital micromirror device) display, electronic powder fluid display, SED (surface conduction emitter display) Technology is being researched.

  This is one technology that can meet all requirements such as high definition, colorization, video display, low energy drive, thinness, light weight, flexibility, robustness, paper-like handling, and low cost. In the future, it will be put to practical use with the most suitable technology according to each request.

On the other hand, apart from such electronic information display technology, conventionally used paper display is not as diverse as information display means for computers such as electronic display displays, but is easy to handle. Some things are hard to throw away.

These means are a combination of electronic display means for displaying by electric control and non-electronic display means for not using such electric control or for displaying by other control means such as heat and light. . The embodiments shown below are examples, and the present invention is not limited to these.

  FIG. 1 is a cross-sectional view of an organic EL element which is an example of an electronic display means suitably applied to the composite display unit of the present invention. A first electrode 2, a charge transporting colored layer 3, and light emission are sequentially formed on a substrate 1. The layer 4 and the second electrode 5 are stacked. In this organic EL element, light emitted from the light emitting layer 4 is extracted through the charge transporting colored layer 3, the transparent first electrode 2, and the transparent substrate 1. The charge transporting colored layer 3 functions as a color filter, and the emission spectrum distribution is corrected and colored light is extracted.

  In the organic EL device applied to the present invention, a hole transport layer or a hole injection layer colored by adding a function such as hole transport or hole injection to the charge transport colored layer, and emitting light Arbitrary luminescent color can be taken out by combining the white light emitting layer with a colored hole transport layer and hole injection layer.

  FIG. 2 is a cross-sectional view of a full color organic EL display applied to the present invention, in which a first electrode 2 is provided on a substrate 1, a red charge transporting colored layer 6 and a green charge transporting property are provided on the first electrode 2. The colored layer 7 and the blue charge transporting colored layer 8 have a structure in which the light emitting layer 4 is laminated on the charge transporting colored layer of these three colors, and the second electrode 5 is laminated on the light emitting layer 4. By finely arranging the charge transporting colored layers (hole transport layer) of these three colors red, green, and blue, red, green, Blue light emitting pixels can be finely arranged, and a full color organic EL display can be formed. Of course, the fine arrangement of the charge transporting colored layer can be used in combination with the fine arrangement of the light emitting layer and a color filter.

  The EL layer provided in the organic EL element applied to the present invention is an organic layer provided between the first electrode and the second electrode facing each other. There is no limitation as long as at least one of the EL layers causes electroluminescence. Moreover, although the EL layer is provided on the first electrode (between the first electrode and the second electrode), even if the EL layer is provided directly on the first electrode, the first electrode and the EL layer are provided as necessary. Another layer may be interposed between them.

  The EL layer of the present invention further includes, as its constituent elements, a light emitting layer, a charge transporting colored layer as an essential layer, a hole transporting layer that transports holes to the light emitting layer, and an electron that transports electrons as an optional layer. A transport layer (sometimes collectively referred to as a charge transport layer), and a hole injection layer that injects holes into the light emitting layer or hole transport layer and an electron that injects electrons into the light emitting layer or electron transport layer An injection layer (these may be collectively referred to as a charge injection layer) can be provided.

Examples of materials constituting these EL layers include the following. First, the charge transporting colored layer is a charge transporting colored layer used in the present invention, which is an organic compound layer having a charge transporting property that increases the light transmittance only in a specific wavelength region. The charge transporting colored layer used in the present invention is composed of a dye or a pigment having a charge transporting property per se, or a dye or a pigment which does not need to have a charge transporting property is dispersed in a charge transporting material. Composed. Further, it may have other functions such as hole injection and hole transport. Examples of dyes and pigments that can be used in the charge transporting colored layer include organic dyes such as triphenylmethane dyes, xanthine dyes, and azo dyes, metal complexes such as metal phthalocyanines and metal complexes azo, and α-Fe ₂ O _3. Inorganic pigments such as CoO.Al ₂ O ₃ and semiconductors having a band gap value in the visible region such as CdS and CdSSe. As a charge transporting material for dispersing a dye or pigment, a hole transporting material described later can be used. When such a material is used, the emission intensity is not adversely affected.

  The thickness of the charge transporting colored layer is preferably 20 to 2000 nm, more preferably 100 to 500 nm, which is thicker than a normal hole transport layer, so that the transmittance outside the selective transmission wavelength region is 20% or less. . When dyes and pigments are used dispersed in a charge transporting material, precipitation and color change are not likely to occur due to the formation of a salt or formation of a charge transfer complex between the dye or pigment and the charge transporting material. This is very important.

  Next, the light emitting layer is a layer having a function of emitting light by providing a field for recombination of holes and electrons, and can inject holes from the anode or hole transport layer when a voltage is applied, and can also be a cathode or electron injection layer. Further, it can have a function of injecting electrons from the electron transport layer and a function of moving the injected charges. Examples of materials that can be used as a material for the light emitting layer include various metal complexes represented by metal complexes and rare earth complexes of oxadiazole derivatives, styrylbenzene derivatives, coumarin derivatives, perylene derivatives, quinacridone derivatives, 8-quinolinol derivatives, and the like. , Polymer compounds such as polythiophene derivatives, polyphenylene vinylene derivatives, polyfluorene derivatives, and mixtures thereof.

  Next, the hole transport layer is a layer having at least one of a function of injecting holes from the anode, a function of transporting holes, and a function of blocking electrons injected from the cathode. Moreover, you may divide | segment into several layers, such as a positive hole injection layer and a positive hole transport layer according to a function. As a material constituting the hole transport layer, for example, a hole transporting low molecule such as a carbazole derivative, a triazole derivative, an oxazole derivative, an oxadiazole derivative, a hole transporting polymer such as a polyvinyl carbazole derivative, a polythiophene derivative, Examples thereof include a material in which a hole transporting low molecule is dispersed using a polymer having no charge transporting property such as polymethyl methacrylate and polystyrene as a binder. It can be used as a hole transporting layer colored by dispersing the above-mentioned charge transporting colored layer material.

  In the present invention, the electrode provided first is referred to as a first electrode, and the electrode provided on the EL layer thereafter is referred to as a second electrode. These electrodes are not particularly limited, but preferably the electrodes are composed of an anode and a cathode. In this case, the first electrode may be either an anode or a cathode. Preferably, one of the anode and the cathode is transparent or translucent.

  The anode preferably has a work function larger than 4 eV so that holes can be easily injected. For example, a conductive metal oxide such as tin oxide, zinc oxide, indium oxide, indium tin oxide (ITO), gold, silver, Examples include metals such as chromium and nickel, inorganic conductive materials such as copper iodide and copper sulfide, organic conductive materials such as polyaniline and polypyrrole, mixtures or laminates thereof, and particularly high conductivity and transparency. From the viewpoint, ITO is preferable.

  The cathode preferably has a work function smaller than 4 eV so that electrons can be easily injected. For example, an alkali metal (for example, lithium, sodium, cesium, etc.) and its fluoride, an alkaline earth metal (calcium, magnesium, etc.) and its Examples thereof include metals such as fluoride, aluminum, and silver, and alloys or mixtures thereof.

  In the present invention, a substrate can be provided. This substrate is provided with an electrode and an EL layer on it, and can be made of a transparent material if desired, but may be an opaque material. The substrate is a sheet or plate, for example, a glass plate such as quartz or soda glass, a metal plate or metal foil, a plastic substrate / sheet such as an acrylic resin, a styrene resin, or a polycarbonate resin. Although used, a transparent material such as glass or plastic is desirable. In particular, plastic substrates / sheets can be reduced in weight, are not easily broken, and are flexible, so that the operability of the display means is close to that of paper, and it is easy to become familiar with the hand during use (when switching to other display means) The feeling of turning the page is close to that of paper), which is preferable.

  The manufacturing method of the organic EL element of this invention will not be limited if it is a method which can manufacture the said organic EL element. Specifically, for example, a step of providing a first electrode on a substrate, a step of forming a red, green and blue charge transporting colored layer on the first electrode, and a charge transport of the red, green and blue A method for producing an organic EL device comprising at least a step of forming a white light emitting layer on the colored layer and a step of providing a second electrode on the white light emitting layer can be used.

  Compared with the conventional general procedure for sequentially providing a color filter, a first electrode, a hole transport layer, a white light emitting layer, and a second electrode on the substrate, the manufacturing process is made by the manufacturing method according to such a procedure. Can be shortened. Note that the arrangement of the color filter, the substrate, and the first electrode in this order is not practical because the parallax increases. Further, since the light emitting layer and the charge transporting colored layer are adjacent to each other, the color purity is further improved as compared with a conventional organic EL device in which the first electrode is sandwiched between the color filter and the light emitting layer. Furthermore, since the formation of the first electrode can be formed on the substrate without interposing a heat-sensitive intermediate layer such as a color filter having a heat resistant temperature of about 250 ° C. at the maximum, the first electrode can be formed at a high temperature. There is an advantage that the resistance value of the first electrode is reduced to about ¼ of the conventional one, the conductivity is increased, and the light emission efficiency of the organic EL element is increased.

  In addition, since the hole transport layer that can be used in the present invention can be thickened, a printing method can be used for forming the hole transport layer and the charge transporting colored layer, and also in this respect Process simplification and cost reduction are possible. Further, the light emitting layer of the EL element needs to be thin and avoid contact with air, and patterning is difficult. However, the present invention is performed on a charge transporting colored layer that is easy to pattern without patterning the light emitting layer. This is advantageous in the manufacturing process.

  Next, with reference to FIG. 3 and FIG. 4, a liquid crystal display element which is an example of electronic display means suitably applied to the composite display unit of the present invention will be described. Here, an embodiment of a reflective liquid crystal display element that requires less power consumption will be described, but the present invention is not limited thereto.

  A reflective liquid crystal display element suitably applied to the present embodiment has a pair of translucent substrates disposed opposite to each other and a liquid crystal material sandwiched between opposing surfaces of the pair of translucent substrates. A liquid crystal display element that performs display using the electro-optic effect of the liquid crystal material, the light reflecting layer and the translucent light on one facing surface side of the pair of translucent substrates. It has a structure in which a scattering layer is laminated in this order.

  As specifically shown in FIG. 3, the liquid crystal display element (reflective liquid crystal display element) 30 has a reflective layer (light reflective layer) 12 and a transparent layer on one surface (opposing surface) of the translucent substrate 11. One of a light-transmitting substrate 21, a signal electrode-side substrate 10 in which a plurality of signal electrodes (liquid crystal driving electrodes) 15 arranged in parallel, and a liquid crystal alignment film 16 are sequentially formed, and a light-transmitting substrate 21 A scanning electrode side substrate 20 in which a plurality of scanning electrodes (liquid crystal driving electrodes) 22 and a liquid crystal alignment film 23 arranged in parallel are sequentially formed on the surface (opposing surface) of the liquid crystal. It has a liquid crystal panel structure arranged to face each other so as to sandwich the material 17. The signal electrode 15 and the scanning electrode 22 are arranged so as to be orthogonal to each other.

  In addition, each “opposing surface side of the translucent substrate” refers to a portion between the opposing surface side of the translucent substrate 11 (or the translucent substrate 21) and the liquid crystal material 17. “The A layer and the B layer are laminated in this order on the opposite surface side” means that the A layer and the B layer have a laminated structure, and the A layer is located closer to the opposite surface than the B layer. It points to that. Therefore, in some cases, another layer may be interposed between the facing surface and the A layer.

  The liquid crystal display element 30 is a simple matrix type liquid crystal display element applied to black and white display, and a predetermined voltage is applied between the intersections of the signal electrode 15 and the scanning electrode 22 so that the liquid crystal material 17 has an electric property. This is a reflective liquid crystal display element that performs display using an optical effect. In this liquid crystal panel structure, the “opposing surface” of each of the translucent substrates 11 and 21 forms the inner surface of the liquid crystal cell, and is sometimes referred to as the “inner surface”. The back surface of the “inner surface” of each of the translucent substrates 11 and 21 is referred to as an “outer surface”.

  Hereinafter, the outline of the manufacturing process of the liquid crystal display element 30 will be described. First, the manufacturing process of the signal electrode side substrate 10 constituting the liquid crystal display element 30 will be described. First, a thin film made of a material having a high reflection characteristic such as aluminum, that is, a reflective layer 12 is uniformly formed in one plane on one surface (opposing surface) of the translucent substrate 11 by sputtering. The layer thickness (film thickness) of the reflective layer 12 is not particularly limited, but is about 1000 mm in the present embodiment. Moreover, the material which comprises the reflection layer 12 will not be specifically limited if it has the desired reflective characteristic, For example, silver etc. can also be used.

  Subsequently, a translucent resin material in which granular silica (light scattering particles) 14 having a particle diameter of 2 μm is substantially uniformly dispersed in an acrylic resin as a base material is uniformly applied on the reflective layer 12 by spin coating, For example, the light scattering layer (translucent resin layer) 13 having a layer thickness of 6 μm was formed by ultraviolet curing. In the present embodiment, as shown in FIG. 3, the light scattering layer 13 is formed so that the reflective layer 12 is completely covered. Further, the thickness of the light scattering layer 13 is not particularly limited, but it is within a range of 5 μm to 15 μm for the reason of suppressing the in-plane distribution of scattering characteristics due to the film thickness distribution while ensuring flatness. More preferably.

  The base material forming the translucent resin material is not particularly limited as long as it has translucency and can be dispersed without altering the light scattering particles. For example, silicone resin, epoxy resin , Etc. can be used instead of acrylic resin. However, an acrylic resin is more preferable from the viewpoint that a flat thin film can be easily formed (planar flatness is good). The light scattering particle 14 is not particularly limited as long as it is a particulate material having a refractive index different from that of the substrate and has a particle diameter equal to or smaller than the thickness of the light scattering layer 13. For example, glass beads, plastic beads, etc. can be used.

  Subsequently, a transparent conductive film made of a transparent (translucent) conductive material such as ITO (Indium Tin Oxide) or the like was uniformly formed on the light scattering layer 13 by sputtering. Then, by patterning the transparent conductive film by a photolithography method, a plurality of signal electrodes (only one is shown) 15 arranged substantially parallel to each other are formed. Then, a thin film made of a translucent material such as a polyimide material is patterned by a printing method so as to cover the signal electrode 15 and flatten the unevenness, and a rubbing treatment is performed on the thin film, thereby aligning the liquid crystal alignment film. 16 is formed. The signal electrode side substrate 10 is manufactured as described above.

  Next, an outline of the manufacturing process of the scan electrode side substrate 20 will be described below. First, a transparent conductive film made of a transparent (translucent) conductive material such as ITO (Indium Tin Oxide) is formed on one surface (opposing surface) of the translucent substrate 21 uniformly by sputtering. Then, by patterning the transparent conductive film by a photolithography method, a plurality of scanning electrodes 22 arranged substantially parallel to each other are formed. Then, a thin film made of a translucent material such as a polyimide material is patterned by a printing method so as to cover the scanning electrode 22 and flatten the unevenness, and a liquid crystal alignment is performed by rubbing the thin film. A film 23 is formed.

  Subsequently, the spacer 18 is dispersed with respect to one (or both in some cases) of the liquid crystal alignment films 16 and 23, and at the periphery of the signal electrode side substrate 10 or the scan electrode side substrate 20 as an adhesive and a sealing material. A sealing resin layer 19 is formed. Note that the sealing resin layer 19 is not formed in a portion corresponding to a liquid crystal injection port (not shown).

  Then, the signal electrode side substrate 10 and the scan electrode side substrate 20 are bonded together with a seal resin 19 interposed therebetween. Next, the liquid crystal display element 30 is manufactured by injecting and filling the liquid crystal material 17 into the liquid crystal cell from the liquid crystal injection port and sealing the liquid crystal injection port. The spacer 18 functions to keep the cell spacing of the liquid crystal display element 30 constant. Further, the signal electrode 15 may function as a scanning electrode and the scanning electrode 22 may function as a signal electrode.

  As described in the above manufacturing process, both the reflection layer 12 and the light scattering layer 13 are uniformly formed in a planar shape. Therefore, a conventional reflective liquid crystal display element (referred to as a conventional liquid crystal display element) which forms a light scattering / reflecting plate by forming a reflective layer (light reflective layer) along the shape on a resin layer having an uneven shape. In comparison, it is not necessary to provide a planarizing resin layer for planarizing the uneven shape. Therefore, it is possible to efficiently manufacture a reflective liquid crystal display element having a target light scattering / reflecting plate (that is, a laminated structure plate of the reflecting layer 12 and the light scattering layer 13 in the present embodiment). .

  Further, in the present embodiment, the reflective layer 12 is formed on the inner surface of the translucent substrate 11 with a very thin layer thickness of 1000 mm, and is considered to have the same flatness as the inner surface. That is, since the light scattering layer 13 is formed on the reflective layer 12 having high flatness, it can be formed with good in-plane distribution and inter-substrate distribution (that is, with good quality stability). In the present embodiment, the thickness of the light scattering layer 13 is 6 μm, and both the in-plane distribution and the inter-substrate distribution are excellent, and the surface flatness is extremely excellent within ± 0.1 μm based on the horizontal plane. The value was shown. Further, in this structure, since there is no layer interposed between the reflective layer 12 and the light scattering layer 13, it is possible to suppress optical loss, and an extremely excellent optical equivalent to the conventional liquid crystal display element. A reflective liquid crystal display element having characteristics (contrast, viewing angle, etc.) can be manufactured with high quality stability.

  As shown in FIG. 4, when the manufactured liquid crystal display element 30 is applied only to the reflection type, the light used for display is on the outer surface side of the translucent substrate 21 (the side where the observer M is present in the figure). Is incident on the liquid crystal display element 30 from the light source 31 for reflection. This light is given to the liquid crystal display element 30 as light transmitted through, for example, a film in which a polarizing plate and a retardation plate are laminated (hereinafter referred to as a polarization retardation plate 27). Scan electrode 22 made of a transparent conductive material (a part of the light passes between scan electrodes 22 and 22), liquid crystal light distribution film 23, liquid crystal material 17, liquid crystal alignment film 16, and signal electrode 15 made of a transparent conductive material. (A part of the light is transmitted between the signal electrodes 15 and 15) and the light scattering layer 13 which is a light-transmitting resin layer are sequentially transmitted to reach the reflection layer 12, and the light is transmitted through the reflection layer 12. Reflected in the direction of the conductive substrate 21.

  The light reflected by the reflective layer 12 is immediately incident on the light scattering layer 13 and is uniformly diffused inside the liquid crystal cell by the light scattering particles 14 uniformly dispersed in the light scattering layer 13 and used for display. Is done. In addition, the light-scattering characteristic (light-diffusion characteristic) of the light-scattering layer 13 is the combination of a base material and the light-scattering particle 14, particle diameter of light-scattering particle, content of the light-scattering particle 14, layer thickness, base material, for example It can be controlled as desired by changing factors such as the degree of dispersion uniformity of the light scattering particles 14 therein.

  The polarization phase difference plate 27 may be disposed between the light source 31 for reflection and the liquid crystal display element 30, and is attached to the outer surface of the translucent substrate 21 and integrated with the liquid crystal display element 30. It may be a thing. By providing the polarization phase difference plate 27, it is possible to obtain a good display quality in the presence of the reflection light source 31. The reflection light source 31 that emits the light is not particularly limited, and may be arbitrarily selected from a natural light source or an artificial light source (such as an auxiliary light source).

In addition, as a translucent board | substrate 11 and 21, although a glass substrate is generally used for the reason of being excellent in dimensional stability etc., emphasizing portability like this invention, and using Considering the particularity of switching to other display means at times, it is desirable to use a translucent plastic substrate (a substrate made of a translucent plastic material). For this reason, the liquid crystal display element 30 according to the present embodiment is preferably applied to monochrome display.
(1) The number of resin layers formed on each of the translucent substrates 11 and 21 is relatively small, and control of dimensional changes is relatively easy.
(2) Strict alignment is basically required only for the positional relationship between the liquid crystal driving electrodes (the signal electrode 15 and the scanning electrode 22), so that a tolerance for a dimensional change is relatively wide.
(3) By being flexible, it is possible to obtain a feeling of use closer to paper (feeling of turning pages) when switching to other display means, that is, easy to adjust to the hand.

  In addition, if a translucent plastic substrate is used instead of a glass substrate, the reflective liquid crystal display element according to the present invention can be made thinner and lighter, and it is difficult to cause breakage such as cracks and cracks. There are advantages. In the present invention, even when a light-transmitting plastic substrate is actually used as the light-transmitting substrates 11 and 21, good display quality can be obtained by applying the display optical system shown in FIG. In the present invention, the plastic substrate is not particularly limited as long as it is a transparent and flexible plastic substrate. For example, polyethylene terephthalate (PET), polyethersulfone (PES), polyethylene naphthalate (PEN) ), Polycarbonate (PC), nylon, polyetheretherketone (PEEK), polysulfone (PSF), polyetherimide (PEI), polyarylate (PAR), polybutylene terephthalate (PBT), or polyimide substrate Yes.

  5 and 6 are partial cutaway views of a microcapsule type display system as an example of other electronic display means suitably applied to the composite display unit of the present invention. The device typically comprises a substrate 40 that is a thin flexible material such as a KAPTON thin film. The row electrodes 42 are preferably deposited on the substrate 40 by a printing process. In the illustrated embodiment, the non-linear backplane 44 is a continuous layer of granular varistor material or granular diode material. The structure shown at 44 can also be a layer of granular silicon, a printed metal contact, and then another layer of granular silicon. Alternatively, the structure 44 can be composed of layers of P-type and N-type doped particulate semiconductor inks printed in an upward pattern, such as PNPNPNPNPNPNP. Any number of layers can be printed, the optimal number depending primarily on the desired breakdown voltage.

  An optional second set of printed row electrodes 46 (shown only in FIG. 5), aligned with the first set (row electrode) 42, provides a contact to the other side of the nonlinear material 44. . An insulating material, such as Acheson ML25208, is printed and applied to the lanes 48 that define the space between the electrodes 42, thereby creating a smooth surface. An electro-optic display 41, such as a layer of microcapsules 47 in an electrophoretic display, is printed on the electrode 46 and, if omitted, on a non-linear backplane 44. A set of transparent column electrodes 49 is printed on the display 41 in a pattern orthogonal to the row electrodes 42 (and 46, if included). Insulating material is printed on the lanes 50 between the electrodes 49. Active pixels are defined in the area of the display 41, where these orthogonal electrode sets overlap. Thus, a display comprising M row electrodes and N column electrodes has M × N pixels.

  7 and 8 show the operation principle of display by the microcapsule 47. FIG. According to this principle, since the microcapsule 47 is coated on a flexible plastic film with an ITO electrode using a silicon resin or the like as a binder, the microcapsule 47 can be freely bent and is familiar with the hand. It is a display means that is easy to handle and very easy to handle.

  FIG. 7 is an example of an electrophoretic microcapsule containing a single type or color of particles. By selectively biasing the electrodes 46 and 49 in a reverse direction, most of the charged colored particles 51 containing spiropyran and a chelating agent and encapsulated in the microcapsule 47 are added to the dye. The turbid fluid 52 moves in the direction of one electrode or in the opposite direction.

  Here, for example, titanium oxide can be used as the colored particles 51 in order to obtain white. In that case, the colored particles 51 are attracted in the direction of the electrode 46 so that the color (now white) can be seen. In the opposite form, the colored particles 51 are attracted in the direction of the electrode 46 so that the particles are not visible by the dye-added suspending fluid 52.

8A and 8B are examples of electrophoresis microcapsules including a plurality of types or colors of particles.
In FIG. 8 (A), there is a suspension fluid 53 made of oil in an electrophoresis microcapsule 47, in which a large amount of charged particles 54 of a single color containing spiropyran and a chelating agent, and another A similar amount of uncharged particles 55 are dispersed in a color or visually contrasting color. Here, the particles 54 and 55 are, for example, titanium oxide (white particles) and carbon black (black particles). When the electrodes 49 and 46 are biased, the charged colored particles 54 move toward the electrode 49 (in this case, the color of the particles becomes stronger, now white), or the electrode 46 (In this case, since the particle 54 is hidden behind the particle 55, the color of the particle 55 becomes stronger. Now, it is black). In this embodiment, each of the particles 54 and 55 is, for example, titanium oxide (white particles) and carbon black (black particles). Spiropyran and a chelating agent are included in the charged particles 54 and the uncharged particles 55. You may put in.

  FIG. 8B shows another method. As shown in FIG. 8 (B), if the particles 54 and the particles 56 of a different color are loaded with opposite charges, a push-pull effect is produced and the visibility of the particles attracted to the electrode 49 is increased. , Can prevent visual interference with particles on the opposite side. In another method, when different sets of particles are made, the charge of the same sign can be changed, but the magnitude of the charge can be changed. In all these embodiments, the electrophoretic mobility of particles 54 and particles 56 is substantially different. It should be noted that when the term “substantially different” is used herein, less than about 25%, preferably less than about 5% of one color particle is the same or similar to the other color particle. Means no electrophoretic behavior.

  In the above description, the organic EL display, the liquid crystal display, and the electrophoretic display have been described in detail, but the electronic display means applied to the composite display unit of the present invention is not limited to these, and besides these, Dispersed particle orientation type display, colored particle rotation type display, PLZT display, DMD (digital micromirror device) display, electronic powder fluid display, SED (surface conduction emitter display) and the like can be applied. In short, the point of the present invention is that a plurality of types of electronic display means are provided and used in accordance with the application.

  Next, a representative example of non-electronic display means suitably applied to the composite display unit of the present invention, and more preferable paper as the non-electronic display means of the present invention will be described. Needless to say, paper has flexibility and is easy to fit in the hand and easily turn pages. Here, paper that is easier to handle is considered.

Paper suitable for the present invention is processed from a plant, the plant tissue is once disassembled, and the orientation (anisotropy) of the cell fiber tissue that the plant originally has in its growth process is randomized to collect the fibers. The body has isotropic properties and is formed into a sheet shape, and the density of the material is set to 0.50 g / cm ³ or more. The density referred to here is a density generally applied in the paper industry, and is calculated by dividing the weight (weight per 1 m ² (grams)) by the thickness ( It is not exactly the same density as in physics).

  This is a display property as a display body and a writing property as a writing means (for example, penetrability of writing ink and not penetrating to the back side) and ease of turning pages when performing these operations. It can be determined by comprehensively considering the strength (rigidity) of the strain. In the present invention, nine types of paper shown in Table 1 were shaped so as to be fastened to the binder 62 as shown in FIG. 9, and 10 sheets of each were prepared and evaluated for ease of use.

  As a result, it was found that Samples Nos. 7, 8, and 9 had low mechanical strength (strain), and they turned around when turning pages, making them difficult to use. Further, it was also found that when writing strongly with a ballpoint pen, deformation (lifting of characters) due to pressing appeared on the back surface, and furthermore, a line of characters due to the pressing appeared on the underlying paper, which was not preferable. It was also found that when these papers were written with a fountain pen, the ink penetrated to the vicinity of the back surface so that it could be clearly seen from the back surface. On the other hand, the other samples were strong, and were very easy to use with no letters floating on the back. Further, the penetration of the ink was not noticeable at all when viewed from the back side.

That is, as in the present invention, when a plurality of sheets of paper as non-electronic display means are used in a bundle, the paper density is reduced to 0 in consideration of a certain level of strength and writing properties such as ink. It has been found that it should be greater than 50 grams / cm ³ .

  As another example of paper, so-called synthetic paper chemically made from fossil fuels such as petroleum, coal, and natural gas can be suitably used as the non-electronic display means of the present invention. Also, a plastic sheet such as an OHP sheet can be used similarly. These are also flexible like the above-mentioned paper, and are easy to adjust to the hand and easily turn pages.

  These non-electronic display means can add information on the surface with various writing tools such as pencils, ballpoint pens, fountain pens, sign pens, etc., and have not only a display function after addition but also a memory function to record and save it. Is. In addition, these non-electronic display means, including other non-electronic display means described below, are simpler in structure than the electronic display means and can be thinned into a sheet shape. It is possible to have a (save) function. That is, since the structure is simple, those functions can be provided on both the front and back surfaces, and the information display or appending (recording storage) function can be easily doubled. Since such a non-electronic display means can easily turn pages, the ability can be doubled without causing any inconvenience in handling even if the functions are provided on both sides of the sheet.

The above various electronic / non-electronic display means are given as examples that can be suitably applied to the composite display unit of the present invention, but it goes without saying that the present invention is not limited to these display means. Nor.
For example, as another non-electronic display means, that is, a display means that does not use electrical control or performs display by other control means such as heat and light, what is called rewritable paper is used. Applicable.

  This rewritable paper, for example, is made by applying a material as described below as a recording layer on a support such as paper or a resin film, giving reversibility to color development by thermal energy control, and reversible display / erasure. Is what you do. There are a transparent white turbid rewritable marking method and a color development / erasable rewritable marking method using a leuco dye, both of which can be recorded by thermal energy control using a thermal head for a thermal recording system.

  The transparent cloudy type is a polymer thin film in which fine particles of fatty acid are dispersed. When heated to 110 ° C. or higher, the resin expands due to melting of the fatty acid. Thereafter, when cooled, the fatty acid becomes supercooled and remains in a liquid state, and the expanded resin solidifies. Thereafter, the fatty acid solidifies and shrinks to become polycrystalline fine particles, and voids are formed between the resin and the fine particles. Light is scattered by this gap and appears white. Next, when heated to an erasing temperature range of 80 ° C. to 110 ° C., the fatty acid partially melts, and the resin thermally expands to fill the voids. If it cools in this state, it will be in a transparent state and an image will be erased.

  The rewritable marking method using a leuco dye utilizes a reversible color development and decoloration reaction between a colorless leuco dye and a developer / decolorant having a long-chain alkyl group. When heated by the thermal head, the leuco dye reacts with the developer / decolorant to develop color, and when rapidly cooled, the colored state is maintained. Next, when it is slowly cooled after heating, phase separation occurs due to the self-aggregating action of the long-chain alkyl group of the developer / decolorant, and the leuco dye and developer are physically separated and decolored.

  In addition, there is a technique that gives reversibility to color development by controlling light energy such as laser light, and performs display / erasure reversibly. For example, a photochromic compound that develops color in C (cyan) when exposed to ultraviolet light and disappears in light of R (red) in visible light, and develops in M (magenta) in ultraviolet light, and G (green) in visible light ) Photochromic compound that is decolored by light, and a photochromic compound that develops color in Y (yellow) when exposed to ultraviolet light and is decolored by B (blue) light, is provided on a support such as paper or resin film. This is a so-called color rewritable paper. This is achieved by expressing the full color by controlling the color density of the three types of materials that develop the colors Y, M, and C, depending on the time and intensity of applying the R, G, and B light once it is turned black by applying ultraviolet light. To do. If the strong light of R, G, and B is kept on, all three types can be decolored to be pure white. Such a device that imparts reversibility to color development by controlling light energy is also suitably applied as the non-electronic display means of the present invention.

  The non-electronic display means applied to the composite display unit of the present invention is not limited to these. In short, the point of the present invention is that a plurality of types of non-electronic display means are provided for use (color / monochrome display). Depending on whether or not additional writing is possible, image formation and erasure by handwritten writing / thermal head or laser means, etc.).

  In any of such non-electronic display means, the display portion has a much simpler structure than the electronic display means, and can be so-called paper or almost the same thickness and lightness as the electronic display means. It can be made thinner and lighter. Further, these non-electronic display means have flexibility, and are easy to adjust to the hand and easily turn pages.

  Furthermore, since such a non-electronic display means is as thin and light as paper, it is easy to handle, such as turning pages, almost like paper, so it is effective to use multiple sheets in a bundle. is there. Specifically, for example, about 2 to 200 sheets are preferably bundled and used.

  Next, the overall configuration of the embodiment of the unit combining various display means according to the present invention will be described with reference to FIGS. In addition, embodiment shown below is an illustration and is not limited to this.

  FIG. 9A is a perspective view when the composite display unit of the present invention is closed, and FIG. 9B is a perspective view when the composite display unit is opened. The composite display unit according to the present invention thus has an outer cover. 60 and a cover fastener 61, which is configured in a book shape, and the outer cover 60 is disposed so as to sandwich the various display means 65 from the outside. Here, the outer cover 60 is thicker than the aforementioned non-electronic display means. This is so that the weak non-electronic display means can be held / supported well when used (for example, when displaying or writing). The material may be a hard plastic material such as a polycarbonate resin, an ABS resin, or a vinyl chloride resin in consideration of an unexpected accident prevention described later.

FIG. 9B shows a state in which the cover fastener 61 is removed and the inside is opened like a book, and the held display means 65 is held by a binder 62.
In the present invention, as the display means 65, as described above, for example, a display using an organic EL for performing color display or moving image display, a liquid crystal display for performing monochrome display or still image display, or a display using electrophoretic particles. Further, paper or the like which is a classic display means is laminated, and a mixed group of such electronic display means and paper is held by a binder 62 (see FIG. 10). Note that paper can be used as a display means and a writing medium because it can be used as a so-called notebook as well as a display means.

  The display means for displaying each of color / monochrome and moving picture / still image is not limited to the above combination, and which display means is used may be appropriately selected by the user. Further, the display means is not limited to the above-mentioned display means, and any other display means may be appropriately combined and used as a mixed group of display means.

  FIG. 11 is a diagram conceptually illustrating only one electronic display means applied to the composite display unit of the present invention and a method for holding non-electronic display means such as paper. The composite display unit of the present invention includes, as the display means 65, electronic display means such as an organic EL display, a liquid crystal display, and an electrophoretic display as described above, and various display means having a writing function such as paper or rewritable paper. The display means or the writing medium is provided with an appropriate combination, but a plurality of holes 66 are provided in the display means or the writing medium, and are fitted by pins 64 of the binder 62 as shown in FIG. 9B. .

  In other words, each of these display means has a compatible shape (in this example, a shape provided with a plurality of holes 66), and each display means can be attached or detached or replaced. It is said. Such a mixed group of electronic display means and various non-electronic display means such as paper can turn pages like a book, so the desired display means can be freely set as required. Can be used.

  Further, as shown in FIG. 10, the binder 62 is rotated and divided into the binder 62a and the binder 62b in the direction of the arrow by attaching and detaching the binder fastening part 62c and the binder fastening part 62d with the rotating part 63 as an axis. The pin 64 is also divided, and the display means (or paper) 65 is detachable. That is, paper or the like accumulated by writing can be replaced with new paper. In addition to the paper, the electronic display means can be easily replaced when a failure or the like occurs.

  In addition, it supplements about the case where a non-electronic display means is replaced | exchanged here. In the present invention, it has been described that it is effective to use a plurality of non-electronic display means in a bundle. In this case, a plurality of sheets can be exchanged together in a bundled state, but it is more preferable to exchange them one by one. This is convenient because, for example, non-electronic display means that are no longer necessary after additional writing (writing) can be removed one by one.

  Next, other features of the present invention will be described. As described above, the present invention is a mixed group of electronic display means and various non-electronic display means including paper. Here, an example in which information input means for such display means is provided. explain.

  FIG. 12 is a perspective view for explaining an example in which the composite display unit of the present invention is provided with a keyboard 67. In this case, the keyboard 67 is provided with a plurality of holes 66 in the same manner as the various display means 65. The pin 62 of the binder 62 is fitted. Usually, it is held in the outer cover 60 like other various display means 65 and is carried. However, like the various display means 65, it is attached and detached so that the shape of the connecting portion is compatible. Since it is a free configuration, it may be used by being removed from the binder 62 and pulled out of the outer cover 60 when used, as shown in FIG. Needless to say, it may be used in a state of being fitted by the pin 64 of the binder 62.

FIG. 12 shows an example in which the keyboard 67 as information input means is held inside the outer cover 60. And it is the best configuration for protecting the keyboard 67 as information input means from external force or the like, or protecting from contamination or the like.
On the other hand, a keyboard 67 as information input means may be provided outside the outer cover 60. In that case, in order to protect each key surface from breakage, contamination, etc., it is set so that it is facing inward so as not to be exposed to the outside. That is, the back side of the key arrangement is configured to also serve as the outer cover. In this way, since the back side of the key arrangement can also serve as the outer cover, at least one side of the outer cover 60 can be omitted.

  FIG. 12 shows an example of a keyboard in which each key has a three-dimensional configuration. However, if the entire keyboard has a flexible sheet-like structure, each key also has a touch panel type, and the entire keyboard is a key sheet that is not a keyboard. When combined with the composite display unit of the present invention, ease of use such as weight reduction, portability, and ease of turning pages is improved.

  Although not described in detail, the present invention provided with such information input means also includes computer means such as information input / output and calculation storage. The computer means is electrically connected to various display means 65 of the present invention. Needless to say, the connection is detachable. The computer means may be configured integrally with such a keyboard or may be configured separately. Further, the computer means may be detachable from the binder 62 like the other various display means 65, or may be an integral configuration incorporated in the outer cover 60 or the like.

  As another information input means, in the present invention, a touch panel method and a handwriting pen input means are also good means. The input tool is not limited to a pen-like object, and a method using a human finger may be employed.

  Although the above example mainly assumes code information input such as characters, a means for inputting image information as bitmap information can be suitably applied to the present invention as another information input means. Specifically, a scanner is preferably applied. In recent years, technology has advanced, and the scanner can also have a considerably thin plate-like configuration, and can be configured to be detachable from the composite display unit of the present invention.

  Furthermore, an image capture means represented by a digital camera / digital video camera or the like may be used as an information input means applied to the present invention. The moving image / still image information obtained by such image capture means is preferably reproduced and displayed by the various display means of the present invention. In the case of the image capture means, it is not always necessary to make it plate / sheet like other various display means, and it may be detachable from the composite display unit of the present invention.

  Next, other features of the present invention will be described. In the present invention, various electronic display means or information input means are integrally bundled and covered with an outer cover 60 as described above. And the usage is often carried and used. For example, assuming a scene that is carried in a bag or the like, various electronic display means in the outer cover 60 may be damaged by external pressure.

Therefore, in the present invention, in addition to the function of simply covering various electronic display means and the like, the outer cover 60 is provided with a function of protecting them from mechanical / physical pressure.
Specifically, in FIG. 9 (A), FIG. 9 (A) shows a state in which the book-like composite display unit of the present invention is closed. In such a book-like shape, Assuming that the outer cover 60 is composed of a front cover, a back cover, and a back cover, the distance between the front cover and the back cover (corresponding to the thickness in the case of a book) is made not to be less than a certain distance. Specifically, a plurality of block-shaped stoppers that determine the distance between the front cover and the back cover are provided on one or both of the front cover and the back cover, and the block height determines the distance between the front cover and the back cover. I am doing so. Needless to say, the height of this block is equal to or higher than the thickness of the entire assembly of various display means held in the outer cover 60.

In addition, the outer cover 60 has a certain degree of mechanical rigidity so that various internal electronic display means are not damaged when a physical external force is applied due to an accident. As a material that can have such mechanical rigidity, a hard plastic material such as polycarbonate resin, ABS resin, or vinyl chloride resin can be used.
In other words, in the present invention, the internal rigidity of the outer cover 60 and the stopper function that prevents the outer cover 60 from closing below the entire thickness of the aggregate of the various display means when it is closed. The various electronic display means are protected from external physical external forces.

  As another configuration, the outer cover 60 itself may be configured as a rigid container, and the entire assembly of various display means may be placed inside the container. As a material constituting such a container, for example, a hard plastic material such as polycarbonate resin, ABS resin, or vinyl chloride resin is sufficient.

  Next, other features of the present invention will be described. As described above, the present invention is a composite display unit that is a mixed group of electronic display means and various non-electronic display means such as paper, and supplies power to such electronic display means. The configuration will be described.

  From the original point of view (display function or writing function), the composite display unit of the present invention functions once if the display means 65 laminated as described above is held by the binder 62. However, in the present invention, as shown in FIG. 9, the display means 65 as the contents is held by the binder 62 and covered by the outer cover 60. This is for protecting the contents which are expensive electronic display means. In the present invention, the outer cover 60 has a function more than protecting the contents. That is, the electronic display means functions as a power supply means.

  Specifically, in the present invention, the outer cover 60 is a battery having a sheet-like configuration. More specifically, a polymer electrolyte battery can be suitably used. Hereinafter, an example of the structure will be described with reference to FIGS.

  In FIG. 13, 70 is a gel polymer electrolyte holding positive electrode unit, and 72 is a gel polymer electrolyte holding negative electrode unit. In the gel polymer electrolyte holding positive electrode unit 70, as shown in FIG. 14, the positive electrode 75 is accommodated in a bag-like support body 77, and the positive electrode 75 and the support body 77 are integrated, and then the gel component-containing electrolyte solution is contained. In this state, ultraviolet rays are irradiated to polymerize the monomer component, and the electrolyte solution is gelled to form a gel polymer electrolyte 76.

  However, FIG. 14 schematically shows the gel polymer electrolyte holding positive electrode unit 70, and the gel polymer electrolyte 76 is illustrated as if formed around the support body 77, but actually When the positive electrode unit is impregnated with the gel component-containing electrolyte solution, the gel component-containing electrolyte solution penetrates into the inside of the support composed of the porous nonwoven fabric. It penetrates and polymerizes and gels there to become a gel polymer electrolyte. However, since the gel-like polymer electrolyte in that portion is difficult to show, it is not shown in FIG.

  In addition, as shown in FIG. 15, the gel polymer electrolyte holding negative electrode unit 72 accommodates the negative electrode 78 in a bag-like support 77, integrates the negative electrode 78 and the support 77, and then contains the gelled component-containing electrolyte. It is constituted by impregnating the solution, polymerizing the monomer component and gelling to form the gel polymer electrolyte 76, and the formation mode of the gel polymer electrolyte 76 in the gel polymer electrolyte holding negative electrode unit 72 is also described above. This is the same as the case described in relation to the gel polymer electrolyte holding positive electrode unit 70.

  In FIG. 13, reference numeral 74 denotes an exterior body made of the laminate film. The exterior body 74 is a unit cell configured by laminating the gel-like polymer electrolyte holding positive electrode unit 70 and the gel-like polymer electrolyte holding negative electrode unit 72. The lead portion of the positive electrode 75 of the gel polymer electrolyte holding positive electrode unit 70 and the positive electrode terminal 71 are connected by welding, and the negative electrode lead portion of the gel polymer electrolyte holding negative electrode unit 72 and the negative electrode terminal 73 are connected. Are connected by welding, and the free end side of the positive electrode terminal 71 and the free end side of the negative electrode terminal 73 are drawn out of the exterior body 74 to constitute a battery.

  Hereinafter, specific examples will be described. In this example, both the positive electrode and the negative electrode are pre-wrapped with a non-woven fabric as a support, and the electrode and the support are integrated, and a heat release sheet is attached to the lead portion, and then each of the gel component-containing electrolysis The solution is impregnated and gelled to form a gel polymer electrolyte. First, the process of integrating the electrode and the support to form an electrode unit (that is, an integrated product of the electrode and the support) will be described.

Production of positive electrode unit:
A polybutylene terephthalate nonwoven fabric [manufactured by NKK, MB1230 (trade name)] having a thickness of 30 μm and a basis weight of 12 g / m ² was used as the support, and this was cut into 200 mm × 320 mm.
After sticking a heat release sheet [Riva Alpha (trade name) manufactured by Nitto Denko Corporation] to the lead portion of the positive electrode, the positive electrode is placed on the left side of the central portion in the length direction of the polybutylene terephthalate nonwoven fabric. After placing the plate on the right side and covering the positive electrode, both sides in the width direction are sealed with a heat-sealing device (trade name: Policyler, manufactured by Fuji Impulse Co., Ltd.). A butylene terephthalate nonwoven fabric was formed into a bag shape, both were brought into close contact with each other, and the positive electrode and the support were integrated to form a positive electrode unit.

Production of negative electrode unit:
After sticking the same heat release sheet as in the case of the positive electrode to the negative electrode lead portion, the negative electrode is accommodated in the same bag-like polybutylene terephthalate nonwoven fabric as in the case of the positive electrode, and the two are brought into close contact with each other. Were integrated into a negative electrode unit.
The positive electrode unit and the negative electrode unit are each immersed in the gelling component-containing electrolyte under reduced pressure for 1 minute so that the positive electrode unit and the negative electrode unit are impregnated with the gelling component-containing electrolyte, and then each is placed in a polyethylene bag. , Sealed.

Next, ultraviolet rays are irradiated for 8 seconds at an illuminance of 1.2 W / cm ² from both surfaces of the polyethylene bag containing the electrode unit using an ultraviolet irradiation device manufactured by Fusion UV Systems Japan Co., Ltd. While the monomer component therein was polymerized, the electrolytic solution was gelled to obtain a gel polymer electrolyte.

  The positive electrode unit and the negative electrode unit that were gelated and retained the gel polymer electrolyte as described above were taken out of the bag, and the hot release sheet was peeled off from the lead portion by blowing hot air at 140 ° C. to 160 ° C. to the lead portion. Thereafter, the gel polymer electrolyte holding positive electrode unit and the gel polymer electrolyte holding negative electrode unit are laminated to form a unit cell, which is an outer package made of a laminate film having a three-layer structure of polyester film-aluminum film-modified polyolefin film. The polymer electrolyte battery was produced by sealing and sealing with

  As described above, in the polymer electrolyte battery, the electrolyte can be formed into a sheet shape, which makes it possible to produce a battery having a large area and a thin shape, for example, A5 plate to A3 plate. A battery using such a polymer electrolyte has excellent safety and storage properties including leakage resistance. In this polymer electrolyte battery, a laminated film having an aluminum film as a core material is usually used as an exterior body, and a unit cell in which a thin sheet-like electrode and a sheet-like polymer electrolyte layer are laminated is covered with the exterior body and sealed. By doing so, a thin battery is finished. Furthermore, since it can be made thin and flexible, a battery that matches the shape of the device can be designed. Therefore, the electronic display means as in the present invention can be suitably applied as the outer cover 60 in the form of a book in which the electronic display means is laminated, and a structure having both a cover and power supply can be obtained.

  In addition, the battery having this sheet-like configuration may be a single sheet in which the front cover, the back cover, and the back cover part of the book-like cover are continuous, or each of the front cover, the back cover, and the back cover part. It is good also as an independent sheet form. Moreover, it is good also as the sheet form divided | segmented by the still smaller area | region.

  By the way, the battery having such a sheet-like structure can be used as a cover or the like as described above, but is not necessarily limited to being used in the present invention. Since such a battery can have a thin sheet-like configuration, the external appearance is the same as the various display means 65 of the present invention, or the attachment portion with the holding means is compatible, and is the same as the various display means 65. It is good also as a structure which can be attached or detached.

Further, the battery having such a sheet-like configuration may be integrally formed with the above-described various electronic display means, that is, mounted on the various electronic display means and detachable together therewith. In such a configuration, since various electronic display means individually have power supply means, even if they are removed from the composite display unit of the present invention, they can function as a single electronic display means.
Needless to say, the power supply means to these electronic display means is not limited to a sheet-like polymer battery, but may be a lithium ion battery or the like.

  As is apparent from the above description, the present invention is configured by laminating and holding various electronic / non-electronic display means, display means capable of displaying various moving images / still images, and display means capable of various color / monochrome displays. It is a display unit. A display suitable for each application, such as when color display is required, when monochrome display is sufficient, when moving image display is required, when still image display is sufficient, and when writing is required There is an advantage that it can be effectively used according to the respective characteristics as means or writing and information display means after writing.
