how to make touch screen display.Touch screens can be divided into five basic types based on technical principles: vector pressure sensing technology touch screens, resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, and surface acoustic wave technology touch screens. Among them, the vector pressure sensing technology touch screen has withdrawn from the historical stage. Infrared touch screen is cheap, but its frame is fragile. Easy to produce light interference, distortion in the case of curved surfaces. The theory of capacitive screen design is good, but its image distortion problem is difficult to be solved fundamentally. The positioning of the resistive screen is accurate, but its price is quite high, and it is afraid of being scratched and vulnerable. Surface acoustic wave touch solves various defects of previous touch screens, is clear and violent, and is suitable for various occasions. The drawback is that the water droplets and dust on the screen surface can make the touch screen dull and even not work.
