Performance characteristics of touch screen

Performance characteristics of touch screen

1. They are all completely isolated from the outside world and are not afraid of dust, water vapor and oil pollution;

2. Can use any object to touch, can be used to write and draw, this is their bigger advantage;

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