Paper Abstract

Matrix addressed liquid crystal (LC) light valves are exerting an ever increasing presence in both direct-view and projection mode display sectors. In transmissive mode the periodic structure of the matrix, when used in conjunction with a backlighting source capable of temporal and spatial modulation, offers the capability to obtain autostereopsis in a useful and economic fashion. This novel combination of complex and proprietary illumination mechanisms with matrix addressed LC valves has been researched and practically validated by the author and various useful configurations defined. From this it has been established that stereoscopic displays can be obtained without either compromise to display surface resolution or requiring the viewer to employ complementary optical devices. The work performed to date has further confirmed that such display constructs may be usefully applied to direct view, projection mode, and helmet mounted systems to the net benefit of operator performance.
