About touch screen

A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal panel device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to pre programmed programs, which can replace mechanical button panels and create dynamic audio and video effects through the liquid crystal panel screen.
Since the emergence of the world's earliest resistive touch screen in 1974, with the development of technology and the growth of application demand, various touch technologies have emerged to adapt to various industries and levels of applications. Nowadays, commercialized touch screen technologies have emerged, including resistive touch screens, capacitive touch screens, infrared touch screens, surface acoustic wave (SAW) touch screens, etc., and have been widely applied in many fields such as mobile phones, tablets, retail industry, public information inquiry, multimedia information systems, medical equipment, industrial automation control, entertainment and catering industry, automatic ticketing system, education system, etc.
