电容或电阻式触摸屏（Capacitive or resistive touch panel） Capacitive or resistive touch screen.Txt love is color balloon, no matter how strict color, can not afford a barbed tip gently. A first-class lover can not only make a woman love forever, but also love a woman all her life! Whats the difference between the resistive screen and the capacitive screen in the touch screen and the multi touch screen? I. from the touch screen screen itself is different: 1. resistance pressure touch screen: The resistive touch screen body part of the screen is a multilayer film and the surface of the display is very complex, which consists of a layer of glass or organic glass is used as the base, the surface coated with a layer of transparent conductive layer (OTI, indium oxide), which is covered with a layer of outer surface hardening, smooth scratch resistant plastic layer. Its inner surface is also coated with a layer of OTI, there are many tiny between two layers of conductive layer (less than 1/1000 inches) of the transparent isolation points separated them insulation. When a finger touches the screen, the two conductive layer OTI a contact point, because the direction of one side of the conductive layer on the Y axis of the 5V uniform field voltage, the voltage detection layer changes from zero to zero, the switch on the controller to detect, A/D conversion, and then the voltage value compared with 5V. You can touch the Y axis point, in that position on the X axis, which is the most basic principle of resistive touch screen in common. The resistance screen is divided into four lines, five lines and other multi wire resistance touch screen according to the number of the outgoing lines. The A surface of the five wire resistance touch screen is a conductive glass rather than a conductive coating layer, and the process of the conductive glass greatly improves the service life of the conductive glass and improves the transmittance. OTI coating the resistive touch screen is thin and brittle fr
