[0002] In prior art, touch screen is usually composed of multiple layers, wherein the outermost layer is a thin layer of silica glass protective layer, and the inner surface and the interlayer are each coated with a layer of ITO. When an object contacts the surface of the touch screen and exerts a certain pressure, the upper layer of ITO conductive layer deforms and contacts the lower layer of ITO, and the coordinates of the touch point can be determined by reading the voltage change.

[0003] The isolation layer of the touch screen conductive layer is an insulating adhesive between the two conductive films. The resistive touch screen is composed of two transparent conductive films, and the transparent insulating adhesive is embedded between the conductive films to ensure that the current lead between the two conductive films does not short circuit. The isolation layer is usually a point structure with uniform distribution, and uses viscous insulating liquid material such as polyester film.

[0004] The isolation layer plays a key insulating role in the touch screen, preventing short circuit between the conductive films and ensuring normal operation of the touch screen.
