  •      The LCD touch screen, also known as the touch panel, is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic button on the screen is touched, the on-screen tactile feedback system can drive each according to a pre-programmed program. A connecting device can be used instead of a mechanical button panel to create a live-action audio and video effect through a liquid crystal display.
  •  
  •      Due to its advantages of light weight, less space, convenience and flexibility, the LCD touch screen has gradually replaced the keyboard as a commonly used human-computer interaction tool for embedded systems.
  •  
  •      According to its technical principle, touch screens can be divided into five categories: vector pressure sensing, resistive, capacitive, infrared, and surface acoustic wave. Resistive touch screens are used in embedded systems.
