RS485 Infrared Touch Panel Linux Windows Ir Sensor Touch Screen
Technology Overview
Infrared touch screen technology operates through a highly integrated electronic circuit system. The touch screen contains a complete control circuit with precision infrared transmitters and receivers installed on opposite sides of a circuit board, creating an invisible infrared light grid. When a user touches the screen, the finger interrupts the infrared beams at that specific position. This interruption causes changes in the electrical signals, which are processed to accurately determine the touch location. Any opaque object can block infrared rays to achieve precise touch positioning.
