How touch screen works
- May 09, 2018 -

For operational convenience, people use a touch screen instead of a mouse or keyboard. When working, the touch screen installed on the front of the display is first touched with a finger or other object, and then the system selects the positioning information input according to the icon or menu position touched by the finger. The touch screen is composed of a touch detection component and a touch screen controller; the touch detection component is installed in front of the display screen to detect the touch position of the user and accepts the evacuation of the touch screen controller; and the touch screen controller mainly receives the touch from the touch point detection device. Information, and convert it into contact coordinates, and then sent to the CPU, it can accept the command sent by the CPU and execute it.
