Abstract
Images to be displayed are produced for left-eye viewing and right-eye viewing in synchronization with a polarization device that alternately changes polarization of the viewed images. In one embodiment, a control mechanism synchronizes modulation performed by microdisplays in a reflective Liquid Crystal On Silicon (LCOS) kernel with an electronically controlled shutter that alternately converts light output from the LCOS kernel between S and P polarizations. Prior to reaching the shutter (or other polarization switching device) a wavelength specific retarder is utilized so that the polarizations of various light channels are homogenous. The kernel installed in, for example, a 3-D enabled monitor, 3-D gaming device, or a 3-D enabled High Definition (HD) LCOS Rear projection television (RPTV). In one embodiment, the LCOS Kernel is an LMS.TM. LiquidVision.TM. or LMS AT.TM. kernel
