touch screen display 40.The working principle of a piezoelectric touch screen is equivalent to a TFT. The manufacturing process is like a capacitive touch screen, and the physical structure is like a resistive touch screen. It is a blend of three mature technologies. Therefore, the piezoelectric touch screen using the new technology combines and enhances the advantages of the resistive and capacitive types, and avoids the disadvantages of the two. Piezoelectric touch screen is generally a multilayer plastic film with a rigid plastic flat (or plexiglass) substrate. The hard plastic flat (or plexiglass) is used as the base layer. The surface is coated with a transparent conductive layer, and the outer surface is covered with a hardened surface. A smooth, scratch-resistant plastic layer, its surface is also coated with a transparent conductive layer, and there are many small transparent isolation points between the two conductive layers. The light transmittance of the screen body is slightly lower than that of glass.
