Abstract: This disclosure describes stereoscopic flat panel display systems based on the polarization encoding of sequentially displayed left and right eye images. The systems comprise line-by-line addressed liquid crystal display (LCD) panels, illuminating back light units and polarization control panels (PCPs). Right and left eye images are written sequentially onto the LCD whose polarization is controlled by a substantially synchronously driven PCP. The backlight may be continuously illuminated, or modulated temporally, spatially or both, as can the PCP.

Abstract: A polarization switch provides substantially ideal binary polarization switching over a broad range of wavelengths using a polarization modulation wheel having at least one retarder stack that transforms polarization. Using the polarization modulation wheel in a polarization system provides a high throughput polarization switch and operates over a wide range of incidence angles while providing substantially continuous and smooth polarization output for each component for any selected polarization basis set. The polarization modulation wheel is well-suited for stereoscopic polarized projection applications.

Abstract: By introducing a stack of alternating high and low index dichroic material layers on the exit surface of a waveguide for a wedge type directional backlight, natural reflectivity differences between polarized components can be increased, effectively reflecting the vast proportion of S-polarized light rays, while at the same time transmitting the P-polarized light rays, of light impacting the exit surface of the waveguide at an angle sufficient to exit the waveguide. This recovers polarization in wedge type backlight systems, increasing illumination exiting the waveguide. Also, on the back reflecting surface of the waveguide, a birefringent material can be added to efficiently transform S-polarized reflected light from the dichroic stack, into returning P-polarized light. Because returning rays that are now P-polarized by the birefringent material have already achieved the critical angle for exiting the waveguide, the rays transformed to P-polarization can now also exit the waveguide, increasing waveguide illumination.
