How The Touch Screen Works

For the convenience of operation, people use touch screen instead of mouse or keyboard. When working, first touch the touch screen installed on the front of the monitor with your finger or other object, and then the system locates the selection information input according to the icon or menu position that the finger touches. The touch screen consists of a touch detection component and a touch screen controller, which is installed in front of the display screen to detect the user's touch position and accept the post-delivery touch screen controller, while the main function of the touch screen controller is to receive touch information from the touch point detection device and convert it to contact coordinates, and then to the CPU. It can also accept commands from the CPU and execute them.
