touch screen display not working.The resistive touch screen (Figure 1 ) is controlled by pressure sensing. The main part is a multi-layer composite film screen that closely matches the display surface. It consists of two conductive layers. It uses a hard plastic flat plate or glass as the base layer. The surface Coated with a layer of transparent oxidized metal (transparent conductive resistance) conductive layer, and then covered with a layer of hardened, smooth and scratch-resistant plastic layer on the outer surface, its inner surface is also coated with a coating, and there are many fine between them (Less than 1/1000 inch) of transparent isolation points separate the two conductive layers from each other. When it is not working, there is a transparent isolation point in the middle to isolate it. When a finger touches the screen, the two conductive layers come into contact at the touch point, the resistance changes, a signal is generated in both X and Y directions, and then it is sent to the touch screen controller. The controller detects this contact and calculates the position of ( X , Y ) , and then operates according to the way of simulating a mouse. Currently, resistive touch screens are mainly four-wire, five-wire, and eight-wire.
