Capacitive touch screen structure
Dec 14, 2017

Capacitive touch screen can simply be seen as a screen composed of four layers of composite screen: the outermost layer is a glass protective layer, followed by the conductive layer, the third layer is non-conductive glass screen, the innermost fourth layer It is also a conductive layer. The innermost conductive layer is a shield that serves to shield the internal electrical signals. The middle conductive layer is a key part of the entire touch screen. There are direct leads on the four corners or four sides to detect the position of the touch point.
