Abstract
PURPOSE:To avoid the surreptitious use of the computer data and the use of a computer without permission by using the special glasses that can view the screen displayed on a CRT through right and left eyes independently of each other synchronously with the switching actions of a screen memory switching part. CONSTITUTION:The data received from a computer are divided into the display data which are written into screen memories 12 and 13 and finally displayed on a CRT 15 and the command data switch control a CRT display device 1. The display data is received from the computer after the secret holding command data in the case of the display data with which the secret of a password, etc., must be held. In this case, a computer interface part 11 converts the display data into those for right and left eyes and writes then into both memories 12 and 13 respectively. At the same time, a picture memory switching part 14 switches both memories 12 and 13 at every frame for display on the CRT 15 and also outputs the right-left eye switch signal to the special glasses 3. Thus those data can be read correctly only when the glasses 3 are used.
