Multiperspective look-around autostereoscopic projection display using an ICFLCD

摘要

DTI has demonstrated a laboratory model of a multiple zone autostereoscopic display with look around capability and a 21' diagonal screen. The display exploits the extremely fast address rates and liquid crystal response speeds associated with ICFLCDs to generate eight to twenty four images during the 1/60th second that a single image is usually displayed. These images consists of the three color components of eight different perspective views of a scene. Optics are used to magnify the images and project them onto a special lens and diffuser screen, which in turn directs light from each image into a different viewing zone in front of the display. Since the perspective views are time multiplexed, each possesses the full resolution of the ICFLCD. An advanced method of generating gray scale using the digital ICFLCD in combination with a time varying light source was also demonstrated. For the most part, off the shelf components were used to construct the key elements of the system including the projection screen and the precision magnifying optics, promising easy commercialization and low production cost. The display is being developed into a prototype, to be followed by production of 1024 $MUL 768 or 1280 $MUL 1024 desktop rear projection display for workstation applications.
