Abstract
A 3-D digital projection display 60 that uses a quadruple memory buffer 63-66 to store and read processed video data for both right-eye and left-eye display. Video data is processed at a 48-frame/sec rate and readout twice (repeated) to provide a flash rate of 96 (up to 120) frames/sec, which is above the display flicker threshold. Data is synchronized with a headset or goggles with the right-eye and left-eye frames being precisely out-of-phase to produce a perceived 3-D image.
