DMD-based time-multiplexed autostereoscopic display

Abstract

The design of a multiperspective, ‘look around’ time-multiplexed autostereoscopic display featuring eight independent viewing zones is described. In order to achieve full-motion colour imagery, a novel high-framerate image projector, based on a digital micromirror display (DMD) with an interface capable of directly linking to commercial graphical processing units (GPUs), is utilised. A high-speed synchronised liquid-crystal display (LED)-based light engine is employed to allow for high-framerate sequential colour imagery. Real-time interactive rendering of multiperspective imagery with standard GPUs has been demonstrated.
