touch screen graphic display terminal.The original touch screen with external surface capacitive technology was a four-layer composite glass layer. The inner surface and interlayer of the glass screen are each coated with an ITO conductive layer, and the outermost layer is a protective layer of silica glass with a thickness of only 0.0015 mm. The inner layer of ITO is used as a shielding layer to ensure a good working environment. The interlayer ITO coating is used as a working layer for detection and positioning . Four electrodes are drawn at four corners or four sides .
