<p>PROBLEM TO BE SOLVED: To permit a user to execute an information processing operation by providing a controller connected to a display device mounted on the head of the user and an input device connected to the controller. SOLUTION: A user 100 mount a display device 103 on the head, views a virtual display screen 104 and executes an information processing operation with an input terminal equipment 101 and a controller 102. The liquid crystal panels for right/left eyes of the display device 103 are mounted on the head and a virtual display screen is obtained. Even if a distance between the liquid crystal panels and the eyes is small by several cm, the device is driven by frame inverse driving for inverting the positive/negative polarities of applied voltage of all picture elements at every frame in a frequency area which cannot be viewed by the eyes of a man. The liquid crystal panel where the semiconductor film of a switching element is constituted of continuous grain boundary crystal silicon is used. The controller 102 is provided with a means receiving information form the input terminal equipment 101, a means storing electronic information and a means sending picture information.</p> |
