摘要： A video processing method and system for generating a foveated video display with sections having different resolutions uses a network channel for communicating video images having video sections of different resolutions, and includes a video transmission system for processing and transmitting the received video images over the network channel. The system assigns a larger portion of the network channel's bandwidth to a video section with higher resolution. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images.

摘要： Viewing angle characteristics of a liquid crystal display (LCD) are improved by reducing the number of subpixels in an image with mid-tone luminance values. In a preferred embodiment, a first table of entries associating subpixel intensity values and subpixel luminance values for a LCD in at least one viewing angle direction is provided. A target intensity value is determined from the first table, corresponding to the average subpixel luminance over a small number of adjacent subpixels. A second table of entries associates the target intensity values with intensity values above and below the target. The adjacent subpixel intensity values are modified according to the second table, thereby reducing the number of subpixels with mid-tone luminance values. The subpixel data is preferably processed within a portion of an application-specific integrated circuit (ASIC), contained within the display module.

摘要： A liquid crystal (LC) lightvalve comprising a twisted nematic LC layer whose molecules are aligned with pixel edges at the mirror backplane, thereby providing improved contrast and efficiency, and reduced visibility of post spacers in black state. The present invention is directed to an LC structure wherein the backplane is rubbed in a direction rectilinear with pixel edges. The LC layer is given the same twist rotation and birefringence as in the conventional TN lightvalve. Polarization control is maintained by illuminating the lightvalve with light whose polarization is rotated by the twist angle relative to the x,y, pixel axes, and by collecting the orthogonally polarized component of the reflected light. The lightvalve top glass is thus rubbed in a direction which is rotated by the twist angle from the horizontal or vertical direction at which the backplane is rubbed.

摘要： A projection display for displaying a color image formed of a plurality of color pixels. Each color pixel has a combination of different color light components. The display has a light source for supplying light to an optical path. A projection lens is disposed in the optical path, as are first and second light valves. The first and second light valves each have a plurality of subpixels. Each subpixel has an associated color filter for reflecting a corresponding color light component. The sub-pixels are grouped into groups of three, each group has a single sub-pixel from one of the first or second light valves and the remaining two sub-pixels from the other light valve, which together combine to form a color pixel of the color image for each of the color pixels of the color image. Lastly, directing means are provided for directing the light from the light source to the first and second light valves and for directing the respective color light components reflected from the light valves towards the projection lens which projects and magnifies the color pixels onto a screen thereby forming the color image.
