42 Inch Optical Touch Screen

42 Inch Optical Touch Screen

The optical module mounted on the top of the touch screen emits light through the LED light, is reflected by the surrounding reflective strips, and returns to the linear optical camera. The compensated light forms a light ray in the touch area and the light gap is not reflected multiple times. 1mm. When a certain point is touched, the emitted light and the received light of the point will form an angle, and the two rays respectively form two angles with the straight line between the left and right cameras, and are controlled by calculating the exact coordinates of the point. Input to achieve touch response.
