DISPLAY DEVICE WITH INDICATING COORDINATE DETECTING MECHANISM

摘要

PURPOSE:To attain the input of required coordinates of an image displayed on a display device having transmitivity of light applied to the whole surface of its display face even when a user is on a position separated from the display device by directly pointing out the image. CONSTITUTION:This system consists of a coordinate indicating device 10 for indicating input coordinates to the display device 20 by light emission, a light receiving detecting device 30 constituted of arraying photoaletectors on the back of the display face 21 like a matrix to detect the light inputted by the device 10 and a detected information input device 40 for detecting an indicated position from the detected light receiving position and inputting the detected position to an information processor 50 and a user can input required coordinates on an image displayed on the display device 20 by directly projecting the light to the coordinates.
