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： Methods and apparatus are provided for a combined image on a head-up display. A data image display provides a first part of a combined image. An optical input provides a second part of the combined image, e.g., the background scene. A combiner superimposes the first and second parts to provide the combined image to the viewer. The data image display preferentially delivers s-polarized light to the combiner, which has a selective reflectance region for preferentially reflecting s-polarized light in a wavelength region of interest. In a preferred embodiment, the data image display comprises a backlight, a liquid crystal layer and two polarizers oriented so that the data images directed toward the combiner are s-polarized with respect to the selective reflectance region. A polarization rotation element may also be used in the data image display to facilitate s-polarization orientation.

摘要： Methods and apparatus are provided for reducing the visual artifacts exhibited by a display employing individually addressable pixels. The apparatus comprises an array of pixels, each pixel having a switchable region of alterable transparency or luminance and a non-switchable region. The switchable region of each pixel is distributed, that is, divided into at least two simultaneously switched portions at least partly separated by a significant portion of the non-switchable region. The first order spatial harmonics and visual artifacts are significantly reduced. For a color display, each color pixel is similarly subdivided.

摘要： A display system and method is provided to increase the ability to recognize and distinguish red, magenta, and various other colors rendered on a display device by dynamically compensating for, at least in part, changes in the human vision system when the display luminance is within the mesopic range. The dynamic compensation enables the display system to be optimized differently depending upon the visual luminance range, be it photopic, mesopic, or scotopic.
