Main types of touch screen
Oct 12, 2018

From the technical principle to distinguish the touch screen, can be divided into five basic categories: vector pressure sensing technology touch screen, resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic technology touch screen. One of the vector pressure sensing technology touch screen has exited the historical stage; infrared technology touch screen cheap, but the outer box fragile, prone to light interference, curved surface distortion; Capacitive technology touch screen design is reasonable, but its image distortion problem is difficult to be solved fundamentally; Resistance technology touch screen positioning is accurate, but its price is quite high.

And is afraid of scraping easily damaged, surface acoustic touch screen to solve the previous touch screen of various defects, clear not easy to be damaged, suitable for various occasions, the disadvantage is that the screen surface if there is water droplets and dust will make the touch screen becomes dull, even do not work. According to the working principle of the touchscreen and the media that transmits the information, the touch screen is divided into four kinds, which are resistive type, capacitive inductive type, infrared type and surface acoustic wave type respectively. Each kind of touch screen has its own advantages and disadvantages, to understand which kind of touch screen is suitable for which situation, the key is to understand the working principle and characteristics of each kind of touch screen technology.
