ICVision: a VLSI-based diffractive display for real-time display of holographic stereograms

摘要

Abstract: The ICVision system is a diffractive display based on VLSI technology. It is designed to display holographic stereograms in real-time. The diffractive display is formed on the surface of standard integrated circuit chips which have been covered with a liquid crystal overlay. Fringing electrostatic fields generated by indium tin oxide electrodes on top of the integrated circuit are used to induce the actual diffractive display. Within the individual IC die making up the display will be computational engines that compute the image to be displayed. Because grating information is encoded in the ITO gratings at the time of chip fabrication, the actual real-time computation is several orders of magnitude less than previous approaches. A large display may be formed by a tessellation of several hundred IC die, each approximately 1 cm$+2$/, on a flat substrate. An optical broadcast system would be used to transfer imagery information into the integrated circuits, obviating the need for wire bond attachments. This paper presents details of the overall architecture of the display system, and details of the holographic grating computations.!4
