Field of the Invention The present invention relates to a silicon pad for a touch panel, wherein the silicon is embedded in a gap between a touch panel and a liquid crystal display window of a touch panel electronic device to display information using liquid crystal and to mount and control a touch panel input device for inputting information. The pad relates to a high-transparent silicon sheet having excellent transmittance, which is closely adhered between the touch panel and the liquid crystal display window to increase the transmittance, thereby increasing the clarity of the display window and improving the reliability of the product by improving the visibility of the liquid crystal display device. There is this.

Transparent touch panels are used in PDAs, automated teller machines (ATMs), unmanned ticket machines, mobile phones, car navigation systems, weather forecasts on television, karaoke rooms, game rooms, etc. It is emerging as one of the new growth industries with continuous progress.

On the other hand, the touch panel is the most popular application of the resistive method, it is configured by facing the two transparent electrode substrates formed with a transparent conductive layer facing each other at intervals of 10 ~ 100㎛, of which the outer side of the movable electrode substrate When the pressure is applied to the screen through a finger or a pen, the movable electrode substrate and the electrode surface of the fixed electrode substrate are in contact with each other, and the position is recognized as a switch, and it operates as a switch. And the like are configured to be inputable.

In general, the touch panel configured to control the display window of the touch panel system and the liquid crystal display (LCD) embedded in the lower part of the touch panel are generally embedded with a gap of about 0.2 mm to 1.0 mm to prevent pressurization of the touch panel. The direct exposure should be avoided. When the touch panel is attached directly to the LCD, it is advantageous to reduce the reflected light on the LCD side and the LCD surface of the lower electrode. Since it must have a load capacity to withstand the pressing force, this configuration without damaging the LCD was practically impossible.

In addition, PDAs and smartphones equipped with a liquid crystal display device having a touch panel are frequently used as a portable device. Since a liquid crystal display device with a touch panel of these portable information devices is generally used outdoors, light sources coming from various directions It can be seen in existence.

Therefore, in addition to light for recognizing an image emitted from a liquid crystal display such as an LCD, there is a problem in that noise light reflected from a touch panel simultaneously enters the eye and makes a display difficult to see.

In order to solve the above problem by forming a protective layer by injecting a gel-type silicon, a binder for maintaining a certain form of the gel-type silicon to be administered between the substrate is indispensable.

However, this has the advantage of absorbing the shock to absorb the shock of the liquid crystal display window when the touch panel is pressed to mitigate the impact, but in the liquid crystal display device of which the transparency is mainly raised, the introduction of the gel-type silicon decreases the transmittance and improves the clarity. The drop has resulted in a drop in the reliability of the electronic device to which the touch panel is applied.

In addition, since the gel-type silicone does not come into contact with the liquid crystal display window due to the insertion of the binder, the adhesive force may be lowered and the gel sheet may be transferred or separated, which causes a malfunction of the product.

Highly transparent sheet type protective layer combines high transmittance, durability and high sensitivity between the touch panel and the liquid crystal display window to reduce the reflection and noise light on the surface while maintaining transparency while alleviating the impact from the touch panel to the liquid crystal display window. It is an object of the present invention to form a.

Accordingly, the present invention has been made to solve the above problems and to form a protective layer having improved visibility between the touch panel and the liquid crystal display window, and the present invention is manufactured to be largely composed of four layers.

It is manufactured to be formed in a stacked form sequentially, the release paper 10, PET film 20, the silicon layer 30, the release paper 40 is a high-transparent silicone sheet is produced by sequentially stacking to achieve the present invention.

The high-transparent silicon pad having the above-described configuration is disposed between the touch panel and the liquid crystal display window of the touch panel electronic device to display information by using liquid crystal and to mount and control the touch panel input device for inputting information. Due to the silicon sheet, the display window may have higher clarity, and the visibility of the liquid crystal display window may be improved, thereby increasing the reliability of the product.

In addition, by forming an adhesive layer to increase the adhesion to the substrate, as well as excellent protection against impact, by applying a PET film and a high-transparent silicone sheet having a transmittance of 95% or more, it is highly applicable to electronic devices to which the touch panel method is applied. There is a feature to form an excellent protective layer that combines transmittance, durability, and high sensitivity.
