Multi function display system.

摘要

The present invention relates to a display (10) having the capability to emit light and form images viewable from both the front (12) and back (14) of the display. The images displayed are seen from both the front (12) and back (14) of the display (10) and appear differently to the front and rear viewer. Electronic shutters (16, 18) are placed between the display (10) and both the front and rear viewers so that they can be flashed on and off fast enough to provide a stable image appearing to each viewer. The shutters also flash slow enough so that display data can be rewritten to provide each viewer with a correct image. The correct image can be either the corrected image of that image seen by the opposing viewer, or a completely separate image. In this way, simultaneous images appear to both the front and rear viewer. These images can be the same or different even though they appear from the same display (10). The use of electronic shutters on displays emitting light from both the front (12) and rear (14) of the display (10), provide the display with multiple functions not possible on conventional displays. <IMAGE>
