Abstract

PURPOSE:To prevent a malfunction for input even if information is inputted with an ordinary writing tool or the like, by superposing thin film-shaped information input elements on the surface of an information display element to constitute a device. CONSTITUTION:An information input element 10 is integrated with a liquid crystal display element 20A as the information display element. Transparent electrode layers 31A and 30A of the display element 20A constitute a matrix electrode, and its operating point arrangement corresponds to the operating point arrangement of transparent electrode layers 13 and 15 in the information input element 10. If polarization directions of polarizing plates 21A and 28A are made orthogonal to each other, the external light is made incident on a liquid crystal display element 20 through the information input element 10. In a part to which an electric field is not applied, the light becomes a linearly polarized light and is stopped by the polarizing plate 28A and does not reach the reflecting face of a reflecting plate 29; and in a part to which the electric field is applied, the light reaches the reflecting face because of the rotation of the plane of polarization and is reflected and is emitted through the information input element 10.

Description

[Detailed description of the invention] (Technical field) The present invention relates to an information input display device.

(Prior art) Input/output devices for computer terminals, input/output devices for word processors, electronic blackboards, electronic notebooks.

There is also a need to develop information input and display devices in connection with electronic toys, facsimile input/output devices, and the like.

This information input/display device is a device in which information can be input by hand, and the input information image can be displayed as is on the input section.

Conventionally, as this type of information input display device, there are two types of information input display devices: one that inputs information using a special input pen such as a light pen, and the other that uses transparent electrode contact that allows information to be input using a normal writing instrument. It is being

However, the former method has the disadvantage that it requires a special pen such as a light pen for input, and the peripheral devices are also complex and costly.

Although the latter method is superior in the ease of inputting information using a normal writing instrument, it does have the problem that errors are likely to occur with fingers or hands during input.

(Purpose) The present invention was made in view of the above circumstances, and
It has a simple structure, can be realized at low cost, and allows information to be input using a normal writing instrument.

(composition) The present invention will be explained below.

The information input display device of the present invention includes 1. /l-1 As shown in FIG.
It has a structure that integrates both seikos.

The information input element 10 has a thin plate shape as a whole and includes a transparent substrate 12, a transparent elastic substrate 14, and a spacer 16.

A first transparent electrode layer 16 is formed on the transparent substrate 12, and a second transparent electrode layer 15 is formed on the transparent elastic substrate 14. The spacer 16 maintains a predetermined distance between the transparent substrate 12 and the transparent elastic substrate 14, and forms a closed space together with both substrates 12,14. This closed space is encapsulated with a highly electrically resistive or electrically insulating encapsulating material (not shown in FIG. 1).

This inner sealing material will be explained in detail later.

Transparent electrode layers 16 and 15 are closely opposed to each other, and these transparent electrode layers 13.15 constitute a matrix-nox electrode. Here, a matrix electrode is a pair of opposing electrodes, at least one of which is formed as a plurality of electrodes that are electrically independent from each other, and whose operating point in combination with the paired electrodes is two-dimensional. M) Refers to an IJ sock-like arrangement.

Transparent electrode layer 13. To give two specific examples of configuring 15 as a matrix electrode, in the first example, the transparent electrode layer 16 is a single plane electrode, and the transparent electrode layer 1
5 is electrically connected to each other (independent microelectrodes are arranged in a two-dimensional matrix.
In this example, both the transparent electrode layers 16 and 15 are arrays of strip-shaped electrodes, and the array directions are orthogonal to each other.

The example shown in FIG. 1 is this second example. That is, the transparent electrode layer 16 has a structure in which narrow strip-shaped electrodes whose longitudinal direction is in the left-right direction of the drawing are arranged in a direction perpendicular to the drawing, and the transparent electrode layer 15 has a structure in which the electrodes are arranged in a direction perpendicular to the drawing. It has a structure in which narrow strip-shaped electrodes whose longitudinal direction is oriented are arranged in the left-right direction in the drawing.

The transparent substrate 12 is integrated with the display surface 208 of the information display element 20. Here, the display surface refers to the information display element 20.
, the surface of the surface on which the displayed information can be observed, that is, the surface of the substrate that forms the information display surface (referred to as the information display surface substrate).When the transparent substrate is integrated with the display surface, it means the following: It has two meanings: 1.
1 means that the transparent substrate is fixedly integrated with the information display surface substrate which is separate from the transparent substrate by suitable fixing means such as adhesive, and 2nd means that the transparent substrate is fixed to the information display surface substrate itself. It means to serve as both, and in this case, the two are literally one.

Here, each part of the information input element will be explained in more detail.

First, the transparent substrate 12 may be made of an elastic material or an inelastic material, such as glass, ceramics, etc.
Examples include polymers such as polyester, polycarbonate, and vinyl chloride.

There is no particular limit to the thickness, but from the viewpoint of strength etc. 50μ
It is desirable that it is more than m.

Next, the transparent elastic substrate 14 is made of polyester.

It is preferably made of a polymer such as polycarbonate or vinyl chloride, and the allowable thickness is about 10 μm to 6 μm, preferably about 50 μm to 1 μm.

The material of the transparent electrode layer 16.15 is In203-x.
lSn, 02-x, ■TO, NESA, Cu
I, Au, Pd, InxCyOz.

Examples include S n XCyOz. The permissible layer thickness range is 50X to 1[1], [101]X, preferably 200 to 5D[]OX.

The material of the spacer 16 is not particularly limited as long as it is electrically insulating, and the allowable size of the gap created by the spacer 16 is 1 μm to 10 mm, and a preferable range is 5 μm to 5 mm. .

In the information input display device of the present invention, since the information displayed on the information display element is viewed through the information input element, it is natural that the information input element is transparent as a whole.

Now, the information display element 20 to be combined with the information input element is a liquid crystal display element, an electrochromic display element,
Electroluminescent display element.

CRT, plasma display element, electric wave display element.

Which of the LED display elements is.

] - Figure 2 shows a configuration in which the information input device 10 is integrated with a liquid crystal display device 2OA as an information display device.

In the figure, numeral 21A indicates a polarizing plate. This polarizing plate 21A
constitutes the information display surface substrate of the information display element 2OA, and the transparent substrate 12 (FIG. 1) of the information input element 10 is integrated with this polarizing plate 21A. Reference numerals 22A and 27A indicate transparent substrates. A transparent electrode layer 31A is provided on each of these transparent substrates 22A and 27A.

Button A is formed. Transparent electrode layers 31A, 30A
Is it a matrix electrode? The operating point arrangement corresponds to the operating point arrangement of the transparent electrode layer 16.15 in the information input element 10. However, this correspondence does not necessarily have to be highly accurate. Transparent electrode 31A, 3
0A is the transparent electrode 15. 13 and f may be the same in terms of material and form. Reference numerals 23A and 26A indicate alignment layers. The alignment layers 23A and 26A are obliquely vapor-deposited layers such as S10, or coatings of polyimide, polyvinyl alcohol, polytetrafluoroethylene, etc., which are then subjected to alignment treatment by rubbing or the like.

The liquid crystal layer designated by the reference numeral 24A is a blend of various substances exhibiting liquid crystal properties, and is an alignment layer 26A.

26A, and its layer thickness is the same as that of the spacer 25A.
Therefore, the size is maintained at around 101x+. Reference numeral 28A indicates a polarizing plate. Moreover, the code|symbol 29A shows a reflective plate. This reflective plate 29A is a plate made of resin or the like with a thin layer of aluminum or the like formed thereon.

By using a liquid crystal layer that rotates the polarization plane of transmitted light by 9D degrees when an electric field is applied to it, when an electric field is applied at any operating point of the transparent electrode layers 30A and 31A, this operating point can be viewed as a bright spot or dark spot via the information input element 10. For example, if the polarization directions of the polarizing plates 21A and 28A are set perpendicular to each other, light from the outside world enters the liquid crystal display element 20 via the information input element 10. In the part where the electric field is not shaded, the light becomes linearly polarized light and is stopped by the polarizing plate 28A and does not reach the reflective surface of the reflecting plate 29. However, in the part where the electric field is applied, the light becomes linearly polarized light due to the rotation of the plane of polarization. , reaches the reflective surface, is reflected, and exits through the information input element.

Therefore, the position of the operating point to which the electric field is applied can be seen as a bright point.

When an electric field is applied at an arbitrary operating point of this matrix electrode, the mink material 21B develops color in the electromagnetic region where the electric field is applied, so that the position of the operating point can be seen as a coloring point. Note that the transparent electrode layer 2
The operating point arrangement of the matrix electrode constituted by 5B and the electrode 24B corresponds to the operating point arrangement of the matrix electrode constituted by the transparent electrode layer in the information display element button.

The electrochromic display element shown in Figure 6 is of a dielectric type, but in addition, an electrolytic solution (perchloric acid in a polar solvent such as propylene carbonate or γ-butyrolactone) is used between the electrochromic substance layer and the electrode. There are electrolyte-type devices injected with lithium (with lithium as a supporting electrolyte), and solid electrolytes (β-A, (hos + P
j) Ag4I5 etc.) A solid electrolyte type electrochromic display element in which K is replaced can be used.

Figure 4 shows a configuration in which an electroluminescent display element as an information display element is combined with an information input element 10. In this example as well, the transparent substrate 12 of the information input element 10
is the information display surface substrate of the electroluminescent display element 20C.

This transparent substrate 12 is provided with a transparent electrode layer 26C. The electrode layer 25C, which forms a pair with the transparent electrode layer 26C and constitutes a matrix electrode, is provided on the substrate 23C.

It has an electroluminescent light emitting layer such as Mn, ZnS; LaF3. The electric Q25C is made of aluminum or the like. When an electric field is applied to an arbitrary operating point of the matrix electrode of the transparent type, consisting of the pole layer 26C and the electrode 25C, light emission by electroluminescence occurs in the part of the light emitting layer 24c where the electric field acts, so that the electric field is acting. The operating point portion can be viewed as a light emitting point via the information input element 10.

What is shown in Figure J-4 is a thin film electroluminescent display element with a double insulation structure.
It is also possible to use a powder electroluminescent display element in which a mixed film of a powder of a phosphor such as S and a synthetic resin such as styrene or acrylic is used and sandwiched between electrodes.

is formed on the substrate 26D. The operating point array of this IJ Fuchs pole corresponds to that of the information input element 10. The electrode 27D is made of IT○ or Ag. Reference numerals 22D and 24D indicate protective layers (at least the protective layer 21D is transparent). Also, code 21D,
25D indicates a dielectric layer such as MgO.

At least the dielectric layer 21D is transparent. The protective layer 22
D, 24D are held in a predetermined gap by a spacer 23D, and the spacer 23D is connected to the protective layer 22D124D.
Together, they form a closed space inside.

A mixed gas 29D is sealed in this space. The mixed gas 29D is made of Ne as a base material, to which Ar or Xe is added as a material, and the sealing pressure is 200 to 50.
It is about 0 torr.

When an AC voltage is applied to an arbitrary operating point of the matrix electrode, the mixed gas at this operating point emits plasma due to the action of the AC electric field. can be viewed through.

Although the plasma display element shown in Figure 5 is an AC type,
A direct current type plasma display element without a dielectric layer can also be used.

A configuration in which 0F is combined with a news input element 10 is shown. In this example as well, the transparent substrate 12 of the information input element also serves as the information display surface substrate of the electrophoretic display element 20F.

The transparent substrate 12 and the substrate 23E are separated by a spacer 24F at a predetermined distance, and a colored dispersion medium 25E and electrophoretic particles 26E are sealed in the closed space formed by the transparent substrate 12 and the substrate 23E and the spacer 24E. .

In Figure 3.8, the fluorescent surface is 21a+-s at °C, and the fluorescent image obtained by irradiating it with an electron beam 22G is
It can be viewed via the information input element 10.

In addition to regular CRTs, CRTs include flat CRTs, FLAN) CRTs that accelerate electrons generated by discharge and hit a fluorescent surface, and FLAN) CRTs that bend electron beams to draw them out. etc. can be used.

Now, the inner sealing material for the information input element will be explained.

The inner sealing material may be a liquid, a granular material, a granular material dispersed in a liquid, a sol-like or gel-like substance, or the like.

First, the case where a liquid is used as the inner sealing material will be explained.

The first requirement for the °C liquid used as the inner sealing material is that it be transparent at room temperature. However, the thickness of the space enclosing the inner sealing material can be made extremely thin, so even if it is not completely transparent, it is sufficient to have transparency to the extent that it does not interfere with observation of information on the information display element through the information input element. 3.2 is that it has high electrical resistance or electrical insulation, and in terms of electrical resistance, it is preferably about 10 Ω or more. The boiling point is preferably 5[]°C or higher.

Specific examples include aliphatic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, alcohols, ketones, esters, alcohol esters, ketone esters, ethers, ketone alcohols, and ethers. Examples include alcohols, ketone ethers, ester ethers, pure water, aqueous solutions, and mixtures thereof.

Considering vapor pressure, toxicity, and ease of handling, C6-c
Saturated hydrocarbons of i5 and mixtures thereof or pure water are particularly preferred.

In Figures 3 and 9, the reference numeral 10A indicates liquid 1 as the inner sheet material.
An information input element using 0 ports is shown.

When a character image or the like is drawn on the transparent elastic substrate 14 with a normal writing instrument 50 such as a pencil or a ballpoint pen, which has a relatively small contact area (Fig. The substrate 14 is recessed, and the transparent electrode layers 13.15 come into contact with each other in the recessed portion, and that portion becomes electrically conductive. This conduction state is detected by a detection circuit (not shown).

However, as shown in Figure 9 CB), 5K, fingertip 60, etc.
Even if the transparent elastic substrate 14 is pressed with something with a large contact area, due to the fluid pressure exerted by the liquid 10 ports on the contact surface,
No conduction actually occurs.

Next, the case where granules are used as the inner sealing material will be explained. The shape of each particle in the granular material is not particularly limited and may be, for example, irregular, one spherical, one cylindrical, etc., but generally speaking, a sphere or a hollow sphere is preferable. Tazoshi, here,
Of course, the outer shape of the sphere or hollow sphere does not need to be a perfect sphere; it is sufficient that it is spherical, and it does not matter if it is slightly distorted or flat.

The granules may be porous. Materials for the granules include glass, MMA, polystyrene, vinyl chloride, various polymer copolymers, alumina, silica, zirconia, carbon, shirasu, aluminone licade, magnesia spinel,
Perlite, fly ash, etc. can be given.

It is preferable that the granules be transparent; however, if the granules are very small, they do not necessarily have to be transparent. In other words, the information display element can be It is sufficient if the displayed information can be observed.Of course, the granules have high electrical resistance or electrical insulation.

Figure j.10 shows an information input element 10B using a sphere 110 as an inner sealing material.

When inputting with a normal writing instrument 50, the transparent electrode easily becomes conductive (Figure 1), and the information is detected by a detection circuit (not shown).

On the other hand, even if something with a large contact area, such as the fingertip 60, touches the transparent elastic substrate 14, no conduction actually occurs (J
Figure -10 (n).

The size of the sphere 1(]0 is allowed to be 0.1 μm to double phase degree, preferably 5 μm to 100 μm and 8 degrees.However, in any case, the size of the sphere 100 is smaller than the thickness of the enclosed space. It won't get bigger.

As the inner sealing material, it is also possible to use a material obtained by dispersing the above-mentioned 1C1 granules in the liquid described above. In this case, various additives may be used to improve the dispersibility of the granules.

It is possible to combine any of the liquids listed above, such as pure water and saturated hydrocarbons, and granules made of any material, such as glass, listed as the granule material.

In FIG. 11, granules = 2 in liquid 100 are used as inner sealing material.
1- in which minute spheres 110 were dispersed was used.

An information input element 10C is shown.

In a normal writing instrument 50, conduction is easily established between the transparent electrodes 15 and 15 due to the input action, but even if something with a large contact area, such as a fingertip, touches the transparent elastic substrate 14 VC, conduction does not actually occur. It will be easily understood that no condition arises.

A sol-like or gel-like substance can also be used as the inner sealing material.

A sol-like substance is a colloidal solid/liquid suspended system, and specifically includes a new liquid sol, a lyophobic sol, a new water sol, a hydrophobic sol,
and these are dispersed in liquid.

Further, the gel-like substance is a colloidal solid/liquid accumulation system, and specifically, it is a colloidal precipitate, a jelly, and a product obtained by swelling these with a liquid.

Figure 12 shows a sol-like or gel-like substance 1 as an inner sealing material.
2 shows an information input element IDD using 2[].

Although it is easy to input with ordinary writing utensils (Fig. 12)
1)) Malfunctions due to contact with fingertips, etc. do not actually occur (
Figure 12 (■)). For objects with a large contact area,
This is because a large reaction force occurs due to the pressure of the sol or gel material.

Now, as mentioned above, the inner sealing material includes (a) liquid, (b) granular material, (ii) granular material dispersed in liquid, (d) sol or gel material, 04 types are possible, therefore, as the inner sealing material, Corella (a), (b)
, (-), and (d) are used, four types of configurations are possible for the information input element.

On the other hand, there are seven types of information display elements that can be combined with the information input element: a liquid crystal display element, an electrochromic display element, an electroluminescence display element, a plasma display element, an electrophoretic display element, an LED display element, and a CRT. Therefore, as an information input display device, 28 combinations of four types of information input elements and seven types of information display elements are possible.

It was confirmed that in all these combinations of temperatures, it is possible to input and display information with a high S/N ratio and by taking advantage of the advantages of each information display element.

Note that the information input/display device operates as follows. As explained in accordance with FIGS. 9 to 12, the information input element used in the information input display device of the present invention is
Irrespective of the inner sealing material, contact with a finger or hand will not cause a malfunction, but a pattern (letter) to be input with a normal writing instrument 50.

When you write a figure (such as a figure, etc.), the transparent electrode 1i1
3.15 conduction state occurs, and information on the position of the operating point at which conduction occurs is detected by a detection circuit (not shown) and stored in a memory (not shown).

When the information display element is a liquid crystal display element, an electrochromic display element, an electroluminescent display element, a plasma display element, or an electrophoretic display element, these display elements have an electrode that constitutes a matrix electrode. Therefore, the information stored in the memory may be transferred to a display electrode selection circuit (not shown), and the necessary electrode portions may be driven by controlling the current from a power source (not shown). Since the matrix electrodes in the display element correspond to the matrix electrodes of the information input element in operating point arrangement, the same pattern as that written and inputted by the writing instrument 50 is transmitted to the information display element. This displayed information can be viewed via the information input element.

In addition, when the information display element is an LED display element, the information stored in the memory is transferred to an LED drive control circuit (not shown), which controls the current from the power supply to display the LED corresponding to the information. By emitting light, the same pattern as that input through the information input element is displayed on the information display element.

When the information display element is a C'RT, the same pattern as the written pattern is printed on the CRT by applying the information stored in the memory to the electron beam scanning control system (not shown). can be displayed.

Furthermore, whichever information display element is used, it is also possible to transform the input cover pattern and display it (for example, by converting text and handwritten input information into print), and it is also possible to display the information by transforming the input cover pattern (for example, by converting text and handwritten input information into type), and by using a computer, etc.
Signals from external devices can be stored in memory and displayed simultaneously with handwriting information.

Hereinafter, specific examples will be described.

We were able to realize a good information input display device that takes advantage of the characteristics of electroluminescent display elements.

<For Examples> As an information input element, as in Example 4.5.6 above,
The type shown in Figure 1D was used. Further, as the information display element, the same liquid crystal display element as in Example 1VC was used.

The transparent substrate 12 in the information input element has a thickness of 1.1 mm.
The transparent elastic substrate 14 has a thickness of o and 1 m.
It is a polyester film of m. The gap between both thread plates 12 and 14 is 50 μm, and the spacer 16 is 50 μm.
A polyester film with a thickness of 0 μm was used.

The encapsulated microspheres are made of polymethyl methacrylate, and the average particle size is 20 μm + V per 1 m7/L.
It was sealed so that ~20 C10 pieces were distributed.

In this case, input was performed with a pressing force of 100 g or less when the tip was 3 mm φ or less, but when pressing on an item with a tip of 1 mm φ or less, conduction did not occur even with a pressing force of 1 kg or more. There wasn't.

In this way, it was possible to provide an information input/display device that has a high input/output S/N ratio, is free from malfunctions, and takes advantage of the characteristics of the liquid crystal display element.

<Example 11> In Example 10, only the microspheres encapsulated in the information input element were replaced with microspheres of polymethyl methacrylate with an average particle size of 10 μm, and the encapsulation distribution was made at a rate of about 50 [] per unit. As a result, the same results as in Example 11 were obtained.

<Example 12> The same information input element as in Example 10 was used in Example 2.
In combination with the same electrochromic display element as in Example 1 to Example 11, a good information input display device was realized.

<Example 13> By combining the same information input element as in Example 10Vc with the same electroluminescent display element as in Example 6, a good information input display device was also realized.

<Example 14> For the information input element and l-, those of the type shown in Fig. A.12 were used. The inner seal has a thickness of 1 mm, and the inner gel material is an aliphatic hydrocarbon gelled with an amino acid-based oil gelling agent. The other parts of the information input element are the same as the information input element in Example IK.

By combining this information input element with the same liquid crystal display element, electrochromic display element, and electroluminescence display element as in Examples 1 and 2.3w,
In either case, a good information input display element could be realized.

Also, Example 1. 4. 7. 1 [The five types of information input devices shown in 1 and 11 can be used as information display devices such as plasma display devices, electrophoretic display devices, LED display devices, and CRTs.
In each case, the characteristics of each display element, that is, the planar structure (plasma display element, electrophoretic display element, etc.) were examined in combination.

LED display element), highly visible plasma display element, electrophoretic display element, LED display element, CR
T), input/display S by taking advantage of high resolution (CRT)
A good information input/display device with a high /N ratio was realized.

(Effects) As described above, according to the present invention, a novel information input/display device can be provided. Since the information input/display device of the present invention is configured as described above, there is no malfunction due to contact with fingers, etc.
Moreover, it can be input easily and reliably using a normal writing instrument, and therefore the input/display S/N ratio is high and the visibility is good. Furthermore, since it is easy to process, it is possible to increase the area and reduce costs. Note that, if necessary, a transparent surface protective layer may be provided on the transparent elastic substrate 14 of the information input element.
Abrasion resistance, scratch resistance, light reflection prevention, etc. can be improved.
