touch screen monitor vga serial

touch screen monitor vga serial.Four-wire resistive technology is a close contact with the display screen glass base layer , FIG. 1 ??of infrared touch screen technology is coated with a thin layer of the outer transparent indium InO, as resistance layer , in the horizontal direction plus 5V to 0V DC working voltage , A uniform and continuous voltage distribution is formed . The conductive layer is covered with a protective layer whose outer surface is scratch-resistant and hardened, and the inner surface is also coated with the same oxide metal layer . The vertical direction is also applied with a continuous DC distribution of 5V to 0V . Voltage . The two resistance layers are separated by many transparent insulation isolation points about one thousandth of an inch ( as shown in Figure 2). When the screen is touched , one of the two resistance layers is connected at the contact position , and the analog voltage Analog-to-digital (AD) conversion , the controller can calculate the x and y coordinates of the contact . Because the outer resistance coating of the four-wire resistive touch screen is frequently pressed ,It is easy to cause cracks and change the uneven voltage distribution of the coating, resulting in the inaccurate calculation of the contact position and the shortcomings of scrapping , and the five-wire resistance technology is created .
