      As a new computer input device, touch screen is currently a simple, convenient and natural way of human-computer interaction. It gives multimedia a new look and is a very attractive new multimedia interactive device. No need to learn, everyone can use it. It is the magic of the touch screen.

Touch screen performance characteristics;

1. They are a completely isolated working environment, not afraid of dust, water vapor and oil stains;

2. It can be touched with any object and can be used for writing and drawing, which is their big advantage;

3. The accuracy of the resistive touch screen depends only on the accuracy of the A / D conversion, so it can easily reach 4096 * 4096. In comparison, the five-wire resistor is superior to the four-wire resistor in ensuring resolution accuracy, but the cost is high. , So the price is very high.
