摘要： A backlight system for a liquid crystal display includes a substantially planar, refractive waveguide having a first major face and a second major face opposite the first major face. The waveguide includes a viewable region corresponding to a viewable area of the liquid crystal display. The system further includes a light source positioned proximate to the second major face and within the viewing region for producing light. An injection feature is proximate to one or more of the second major face and the first major face and within the viewing region to optically couple the light into the waveguide such that the light becomes waveguided light. A plurality of extraction features is proximate to one or more of the second major face and the first major face and within the viewing region to optically couple the waveguided light out of the waveguide.

摘要： A system and method for optimizing image uniformity in a head-up display (HUD) are provided. An imaging subsystem is characterized in that if light of a first uniformity is propagated therethrough, an uncompensated image would be displayed to a user via uncompensated image light. The uncompensated image light has first and second portions with respective first and second values of a radiant property. A difference between the first and second values is a first amount. The light source is configured to emit source light of a second, predetermined uniformity through the imaging system such that a compensated image is displayed to the user via compensated image light. The first portion of the compensated image light has a third value of the radiant property, and the second portion of the compensated image light has a fourth value of the radiant property. A difference between the third and fourth values is less than the first amount.

摘要： A method and apparatus according to various aspects of the present invention provides a polarized display exhibiting reduced reflectances. A polarizer is disposed adjacent to a cover glass in front of the display. Light intended to be transmitted by the display is transmitted by the polarizer. Light reflected after passing through the polarizer reverses polarization, and is absorbed as it intercepts the polarizer following reflection.

摘要： A polarization-sensitive scattering element (PSSE) that acts to effectively separate light of different polarizations. The PSSE is a microstructural composite of material domains having differing birefringence. The PSSE has a first scattering distribution for light rays of a first polarization and a second scattering distribution for light rays of a second polarization. The first scattering distribution is such that the majority of the light rays of the first polarization are randomly backscattered. The second scattering distribution is such that the majority of the light rays of the second polarization are substantially transmitted. The PSSE provides a means for recapturing light energy which would otherwise be lost in display devices, while reducing degradation and heat build-up due to light absorption.

摘要： A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.
