摘要： Disclosed is an optical valve or light valve for providing large area collimated illumination from localized light sources, and system and method thereof for 2D, 3D, and/or autosteroscopic displays. An optical valve may include a stepped structure, in which the steps include separated extraction features which may be optically hidden to light propagating in a first direction. Light propagating in a second direction may be refracted, diffracted, or reflected by the features to provide illumination beams exiting from the top surface of the optical valve. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality.

摘要： 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.

摘要： Methods and systems are disclosed to provide intra-pixel illumination to a modulating display panel, where regions of a pixel are provided incident light with controlled intensity and color at different periods of the panel's addressing cycle. This can lead to increased resolution beyond that intrinsic to the panel's physical make up, providing an enhanced resolution 2D panel, as well as a high resolution panel suitable for autostereoscopic purposes when used with a further lens array. For example, when the left hand side of all pixels are illuminated in one frame creating an image, and the right hand side of the pixels are illuminated within a second frame creating a further image, then the combined image, assuming temporal averaging, is twice the native resolution. Despite the temporal trade off, the eye's tolerance to local variation of color and intensity makes this feasible with realistic addressing periods.

摘要： A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. The first set of spectral emitters generate a first light bundle and the second set of spectral emitters generate a second light bundle. Several modes of operation may be provided including (1) an advanced 2D mode, (2) an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters, (3) a privacy screen mode, (4) a channel multiplexed mode, and (5) a stereoscopic image mode. The latter three modes utilize the first and second set of spectral emitters to alternately illuminate a portion of the light modulating panel. Images and representations generated by the direct view display operating in the latter three modes are viewed using appropriate eyewear having filters with passband characteristics to transmit the respective light bundle.

摘要： Stereoscopic display systems including a position-tracking system that determine the position of the stereoscopic eyewear worn by a viewer. An exemplary embodiment of the eyewear includes retro-reflective reflectors that are illuminated by an infrared illuminator proximate to or optically co-axial with a capturing camera. Suppression reflections from other reflective features in the vicinity may be achieved by control of the polarization of the infrared light.

摘要： A method and apparatus for selectively blurring parts of an image set according to differences in disparity between successive images. As a result, the one-dimensional ‘ringing’ edge artifacts, intrinsic to autostereoscopic displays, are hidden, thereby improving the perceived image quality of a multi-view autostereoscopic image. The method may involve detecting regions of disparity between adjacent views, and then blurring those regions by weighted local pixel averaging. The relationship between the blur radius and the disparity is preferentially non-linear to maintain sharpness of low disparity regions.

摘要： A method and apparatus for providing optimal correction to depth mapping between captured and displayed stereoscopic content. The solution is derived in a continuous form that can be implemented through CGI scaling techniques compatible with image rendering techniques. Similar correction can be implemented with variable depth-dependent camera separation and disparity re-mapping. The latter is applicable to correcting existing stereoscopic content.

摘要： A segmented polarizing device may be a polarizing modulator which may include strips of switching polarizer material. The switching polarizer material may be used to switch individual segments of the polarizing modulator at a time. In such devices, the polarizing modulator may be one or more liquid crystal cells (LC cell). As the LC modulation panel of a display refreshes an image from top to bottom, changing from left eye content to right eye content, the polarization of a corresponding part of a scrolling polarizing screen may change along with the display.
