A projection-based multi-view time-multiplexed autostereoscopic 3D display system

This paper presents our implementation of a multiview autostereoscopic 3D display system by using timemultiplexing approach, Digital Micro-mirror Devices (DMD), and the optical Wedge (R). The whole system consists of three major parts: high frame rate DMD projector, an active shutter, and an optical Wedges. This research investigates and develops the approaches to interface and control DMDs at very high bit rates and ultra-high frame rates to drive a novel flicker-free 3D flat panel device, with a wide viewing area and without need of special viewing glasses or head-tracking system. It needs to design a digital interface circuit capable of receiving video image data in a conventional format and translating it into a form appropriate for display on a DMD light modulator. This approach differs from existing ones in that it facilitates the modulation of the DMD to achieve much high frame rates, though with a trade-off in greyscale resolution. The outcomes of this research will have the great potential for commercialising the autostereoscopic display systems.
