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.

A liquid crystal display is provided. The liquid crystal display includes a liquid crystal display panel having pixels configured to form an image; and a backlight system proximate to the liquid crystal display panel and configured to illuminate the pixels of the liquid crystal display panel. The backlight system includes a light guide including a plate portion generally parallel to the liquid crystal display panel and a first side portion extending generally perpendicularly from the plate portion, a light source configured to emit light into the light guide via the first side portion, and a heat sink coupled to the light source and configured to remove heat generated by the light source during operation.

A three dimensional viewing assembly includes a first display, a second display, and a beamsplitter. The first display is for displaying a first image. The second display is for displaying a second image. The beamsplitter is disposed at least partially between the first display and the second display, and is configured to receive, and to optically overlay, the first and second images. The beamsplitter comprises a first surface, a second surface, and a mirror. The first surface at least partially faces the first display, and the second surface at least partially faces the second display. The mirror is disposed between the first surface and the second surface.
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:
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.
摘要:
A display system and method for providing user adjustability of displayed three-dimensional images. The system simultaneously displays a left-eye perspective view of an image and a right-eye perspective view of the same image, at a separation distance, and allows for the selective control of the separation distance via, for example, a user interface. The system and method allows multiple users to use multiple pieces of display hardware and quickly return each piece of display hardware to a user's own individualized preferences and compatibilities. It additionally allows a user to vary the display properties, such as providing extra foreshortening or stretching along the depth axis, quickly and simply.

A modular and scalable seamless tiled display apparatus includes multiple display devices, a screen, and multiple lens assemblies. Each display device is subdivided into multiple sections, and each section is configured to display a sectional image. One of the lens assemblies is optically coupled to each of the sections of each of the display devices to project the sectional image displayed on that section onto the screen. The multiple lens assemblies are configured to merge the projected sectional images to form a single tiled image. The projected sectional images may be merged on the screen by magnifying and shifting the images in an appropriate manner. The magnification and shifting of these images eliminates any visual effect on the tiled display that may result from dead-band regions defined between each pair of adjacent sections on each display device, and due to gaps between multiple display devices.
