Development of Time-Multiplexed Backlight on Auto-stereoscopic LCD for Multi-user and Wide-viewing Angle Function

Abstract

Current Time-Multiplexed backlight system can only produce a single user 3D display. Thus, a multi-user 3D film was proposed to add in front of the directional sequential backlight system and make the display for three users. Furthermore, a high resolution time-multiplexed backlight with tracking system for multi-user applicable wide-viewing auto-stereoscopic LCD was proposed. By utilizing an adjustable fine-stripe (AFS) backlight structure with a temporal switched 120Hz LCD, the 3D image could be displayed on high resolution, thus multi-user can observe wide-viewing 3D images at the same time.
