By using optical sensors at two corners of the screen, lighting irradiates the sensing area and reflects back to camera to detect fingers. Via precise calculation, system will get the coordinates of the fingers caught by camera with no contact pressure required. We call this technology “OPTICAL TOUCH” which is the best technology currently for large scale of touch display. And, the patent has already been registered in major market of the world. With this technology, the accuracy and system speed is perfect, and multi touch function is also available.
Strengths
Optical touch panel is suitable for equipment of general use and requiring level reliability. With Exceptional precision multiple touch points, user can touch the screen anywhere by a finger, a pen, even the lightest touch will be registered.
Applications
