Infrared touch screen is the use of X, Y direction of the dense infrared matrix to detect and locate the user's touch. Infrared touch screen in front of the monitor to install a circuit board frame, the circuit board in the four sides of the screen are arranged infrared emission tube and infrared receiver tube, Infrared Touch Screen one by one corresponding to the vertical and horizontal cross-infrared matrix. When the user touches the screen, the finger will block the two infra-red lines passing through the position, so that the position of the touch point on the screen can be judged.
Infrared touch screen main features
1, a high degree of stability will not drift due to changes in time and environment.
2, a high degree of adaptability from current, Infrared Touch Screen voltage and electrostatic interference, suitable for some harsh environmental conditions.
3, high light transmission without intermediate medium, high light transmission, up to 100%.
4, long life Long durability, not afraid of scratching; Infrared Touch Screen touch density up to 4096 * 4096, touch life is extremely long.
5, the use of good characteristics Touch no effort, no special requirements on the touch body, no matter whether the touch object is a hard object, the touch object is conductive, Infrared Touch Screen does not affect the normal use;
Infrared touch screen technology features
The advantage of an infrared touch screen is that it can be touched with a finger, a pen, or any object that blocks the light.
It can be said that the infrared touch screen LCD has a great advantage. Infrared ray touch screen infrared detection technology using the same wavelength infrared emission tube, infrared receiver can get a simple infrared detection method. Moreover, as long as there are objects blocking the connection between the infrared tube, the reception signal drops sharply, so the infrared can detect the object blocking, anti-theft systems, Infrared Touch Screen automatic sensing systems, counters and other systems widely used.
