触摸屏显示器批发。接触点的位置是通过x轴和y轴电压值??的ITO接触点。五线电阻式触摸屏需要四根导线在ITO的内层，只有一根导线在ITO的外层。触摸屏上有五根导线。特点:分辨率高，传输响应速度快。表面硬度高，减少划伤、划伤及化学处理。它仍然可以使用后，3000万接触在同一点。导电玻璃是基片的介质。一次性校准，稳定性高，永不漂移。1.3电阻式触摸屏的局限性无论是四线电阻式触摸屏还是五线电阻式触摸屏，都是一种与外界完全隔离的工作环境，可与任何物体接触，可用于写字和绘图。 It is more suitable for limited people in the field of industrial control and offices. The common disadvantage of resistive touch screens is that because the outer layer of the composite film is made of plastic materials, people who do n??t know too hard or use a sharp touch may scratch the entire touch screen and cause scrap. However, within the limits, the scratch will only hurt the outer conductive layer. The scratch of the outer conductive layer is irrelevant to the five-wire resistive touch screen, and it is fatal to the four-wire resistive touch screen. 2. Capacitive touch screen 2.1 Capacitive technology Touch screen uses the human body's current sensing to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Lead out four electrodes, and the inner layer of ITO is a shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the electric field of the human body, the user and the touch screen surface form a coupling capacitor. For high-frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current is flowing from the electrodes on the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller calculates the position of the touch point through accurate calculation of the four current ratios. . 2.2 Defects of capacitive touch screen
