An optical contact controlled medium display includes a computing device (1) containing at least one information, an indication device (2) connected to the computing device via a video signal unit (4) to indicate the at least one information of the computing device, and an optical position detection device (3) mounted on the indication device and electrically connected to the computing device. Thus, when the indication device is provided with a touch point (24), the optical position detection device detects a position signal of the touch point from the indication device and transmits the position signal of the touch point to the computing device so that the computing device can compute a position of the touch point.
