interactive screen meaning.(2). Emerging CCD infrared optical touch technology principle is top mounted 2 th CCD camera, the top left CCD camera , by the infrared LED lamp tube emit light , after four weeks reflection bar reflection , enters the top right CCD camera head . In the same way , the light emitted by the CCD camera in the upper right corner is transmitted to the CCD camera on the left . The dense light forms an infrared light network in the touch area, and the space between the light reflected multiple times is within 1MM . When you touch a point, the emitted light and the received light at that point form an included angle. At the same time, the CCD camera at both ends and the two lines and the straight line formed between the two cameras will form two included angles, so that the point is accurate. Coordinates are entered by the controller to achieve touch response.
