dorman touch screen infotainment display 599-942.This touch screen uses pressure sensing to control the resistance . The main part of the touch screen is a resistive film screen that matches the surface of the display. This is a multilayer composite film. It uses a glass or hard plastic flat plate as the base layer, and the surface is coated with Layer of transparent oxidized metal (transparent conductive resistance) conductive layer, which is covered with a layer of hardened, smooth and scratch-resistant plastic layer on the outer surface, and its inner surface is also coated with a coating, with many small ( (Less than 1/1000 inch) transparent isolation points separate the two conductive layers. 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. This is the most basic principle of resistive technology touch screen. So the resistive touch screen can be operated with harder objects. Because the outer conductive layer is frequently touched, the purpose of using a ductile nickel-gold material is to extend the service life, but the process cost is relatively high. Although the nickel-gold conductive layer has good ductility, it can only be used as a transparent conductor. It is not suitable as a working surface of a resistive touch screen because of its high conductivity and the metal is not easy to achieve a very uniform thickness. It should not be used as a voltage distribution layer. It can only be used as a probe. Floor.
