The main type of touch screen

- May 09, 2018-

Differentiating touch screens from technical principles can be divided into five basic categories: vector pressure sensing technology touch screens, resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, surface acoustic wave technology touch screens. Among them, the vector pressure sensing technology touch screen has been withdrawn from the stage of history; the infrared technology touch screen is low in price, but its outer frame is fragile, it is easy to produce light interference, and distortion is caused in curved surfaces; capacitive technology touch screen design concept is reasonable, but its image distortion problem is difficult to obtain. Fundamental solution; resistance technology touch screen positioning accuracy, but its price is high, and fear scratch easily; surface acoustic wave touch screen solves the various defects of the previous touch screen, clear is not easily damaged, suitable for all occasions, the disadvantage is the screen surface Water droplets and dust can make the touch screen dull or not even work.
