8 inch touch screen display.The capacitive technology touch screen is a four-layer composite glass screen, as shown in the figure below. 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, and four electrodes are drawn at four corners or four sides.
