[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display 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 a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through liquid crystal display screens. With the development of science and technology and the growth of application needs, various touch technologies have been born to adapt to applications in various industries and levels. Today, commercial touch screen technologies have been formed, including: resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, surface acoustic wave technology touch screens, etc.
