IR touch frame’s operating principle is to install a circuit board outer frame in front of this display, and arrange infrared emitting tubes and infrared receiving tubes around the screen to form a horizontal and vertical cross infrared matrix. When user’s finger or other object touch screen, it will block infrared ray though this position,which is defected by corresponding infrared receiver tube.The position of this touch can be judged by defecting which IR receiver tubes have lost signal.

IR touch screen frame has high sensitivity,high stability and wear resistance and other advantages,which is suitable for intelligent terminal,industrial control,multimedia teaching and other areas.It is free from current, voltage and electrostatic interference, which is suitable for some harsh environmental like Explosion-proof and dust-proof and so on.In addition,infrared touch screen overlay’s light transmittance without intermediate medium,and the highest can reach 100%.It has long service life,which is not afraid of scratches, and has a long touch life.

IR touch frame support multi touch that allow recognize and trail after multiple simultaneous touch points to achieve pinch, zoom, rotate, and other multi-finger gestures.They always support all kinds of operation system, including Windows,MACOS,Android and Linux.It can use cooperatively with any application that supports touch input.In install, IR touch frame is usually fixed in the front flap of the display by tape or bracket.Its design is suitable for the display’s size,from small screen to large interactive panel.On the multi touch,IR touch frame can support multi touch points, which is suitable for different touch gestures and operation requirements.
