It is used in display devices such as T, LCD elements, EL elements, and PDPs, and by pressing an arbitrary point on the panel, the coordinate position corresponding to the pressed point is detected.

面でも問題があった。Conventionally, this type of film-type transparent touch panel has two transparent conductive films on which conductive wave films are formed facing each other, and a dot spacer or the like is provided on at least one side to maintain a constant distance between the two films. It is made of m-structure, which is glued together. However, with this film method, malfunctions are likely to occur due to deflection that occurs when two films are pasted together, especially when the area is large. There is a need to. However, in this case, not only a portion of the Tonto spacer but also a considerable portion around it becomes a blind spot, and the advantage of high resolution is lost. In addition, since the transparent conductive film is hard, when inputting data on the touch panel surface using a pen, etc., the film bends around the dot spacer, easily causing the conductive film formed on the transparent conductive film to peel off, resulting in poor durability. There were also problems in terms of

いのでスイ・ソチとして作動しないことがあり、このよ
うに透明感圧導電層のみでは、スイッチ機能に問題が多
く実用的でなかっな。Separately, a transparent touch panel has been devised in which a transparent pressure-sensitive conductive layer is provided between two films instead of a dot spacer (Japanese Patent Laid-Open No. 61-243622).
If the pressure sensitivity of the transparent pressure-sensitive conductive layer is increased, malfunctions may occur due to film deflection, and if the pressure sensitivity is decreased, the resistance will not drop sufficiently even when input pressure is applied, so it will operate as a switch. Therefore, using only a transparent pressure-sensitive conductive layer has many problems with the switch function and is not practical.

It consists of a piezoconductive layer and an insulating pattern deposited either on the transparent pressure-sensitive conductive layer or on the surface of the substrate without the transparent pressure-sensitive conductive layer, and the first and second parallel N jll are This is a transparent Y-chi panel characterized in that the constituent surfaces of both substrates are arranged in contact with each other so as to be perpendicular to each other.
本発明に用いられる透明導電性の基板は、第１の基板お

性能および寿命に欠けるものとなり、２５０μｍを超え
る場合には可とう性が乏しくなって好ましくない。The first substrate in the present invention is placed on the operation surface side, and needs to have a certain degree of surface deflection and restoring force against pressure. Its thickness is 50~2
It is preferable to use a flexible film or sheet in the range of 50 μm, or even in the range of 75 to 200 μm; if the thickness is less than 50 μm, the strength will be weak and the switch will lack performance and life; if it exceeds 250 μm. This is undesirable because the flexibility becomes poor.

A range of 75 to 2000 μm is more preferable. If it is less than 50 μm, the strength will be weak and it will be difficult to use. If it exceeds 3000 μm, there will be no strength difference, but the thickness of the entire transparent touch panel will be reduced. It becomes disproportionately thick and is also economically unfavorable.

る。The electrodes configured on the above substrate are provided in parallel on the surfaces near the opposite sides of the first and second substrates, and are formed using conductive fine particles such as silver, graphite, carbon black, etc., and a matrix. This can be carried out by printing a conductive paint (ink) made of a polymer.
The first and second substrates with parallel Z lli are arranged such that the two sets of parallel electrodes are perpendicular to each other.

状導電粉は透明性が高い導電粉として特に好ましい。Next, the transparent pressure-sensitive conductive layer to be applied to at least one of the first and second substrates is formed by markings 11 made of a paste made of a transparent polymeric elastic material with fine conductive powder dispersed therein. . The guidelines for selecting the polymeric elastomer used for this transparent pressure-sensitive conductive layer include its transparency when formed into a film, whether it can be screen printed with a wide range of applications, and whether it can be used as a substrate. Adhesion to is also an important point. In this respect, examples include silicone rubber, polyester elastomer, and polyurethane elastomer. The conductive powder used has high conductivity and has a size of 0.1μ without losing transparency.
m or less is preferred, and colloidal conductive powders made of tin oxide and antimony oxide, or tin oxide and indium oxide are particularly preferred as highly transparent conductive powders.

た不感点部分が大きくなって好ましくない。Next, the insulating pattern provided on either the transparent pressure-sensitive conductive layer or the substrate without the transparent pressure-sensitive conductive layer is an insulating paste with a matrix of polymer elastic material such as synthetic rubber or thermoplastic elastomer. It is formed by printing etc. Criteria for this material include whether it can be used for screen printing with a wide range of applications, and whether it has good adhesion to transparent pressure-sensitive conductive layers and substrates in terms of durability. In this respect, examples include insulating pastes of silicone rubber, polyester elastomers, and polyurethane elastomers. This insulating pattern is intended to increase the reliability of the switch function, and may be dot-shaped with a diameter ranging from 30 to 300 μm.
Formed in either a striped or lattice shape with a line width in the range of 30 to 300 μm and a thickness of 2
It is in the range of ~50 μm. If the size is less than this, the reliability of the switch is insufficient and the durability is disadvantageous. If it exceeds this size, the resolution will decrease, and when the pen is slid, the pen will feel uneven, resulting in a poor operating feel, and the blind spot will become large, which is undesirable.
