摘要： A liquid crystal device comprises an active matrix substrate (6) and a counter-substrate (7) provided with homeotropic alignment surfaces (11). A layer of nematic liquid crystal material is provided between the alignment surfaces (11) so as to form a vertically aligned nematic device. The substrates (6, 7) carry a pixel electrode arrangement and a counter-electrode arrangement which define a plurality of pixel regions. Each of least some of these regions has a pixel electrode (13), which may be split into two halves, and a counter-electrode (8) which are arranged to apply an electric field for controlling the liquid crystal director (12) out-of-plane tilt angle. A further electrode (14), for example in the form of a plurality of parallel fingers, cooperates with at least one of the other electrodes (8, 13) to apply a second electric field for controlling the director in-plane azimuth angle. Such a device may be used, for example, as a switchable public/private display.

摘要： A method of processing image data for display by a display panel of a display device. The method comprises receiving main image pixel data representing a main image and side image pixel data representing a side image, and performing a mapping of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. A compression of the main image pixel data is performed in advance of or at least partly incorporated into the mapping, the compression being performed at least partly in dependence upon the main image pixel data and at least partly in dependence upon how the off-axis luminance varies with pixel data input to the mapping.

摘要： A method and apparatus is provided for reducing color shift in relation to viewing angle in an LCD. The method includes receiving a plurality of pixel data constituting an image, each pixel data including a plurality of sub-pixel color components having respective data values; for each of the pixel data, comparing the sub-pixel color component data values included therein; and based on the comparison, modifying the sub-pixel color component data values included in the pixel data to reduce color shift when displayed on the LCD.

摘要： A display device is provided that comprises a liquid crystal display panel for displaying an image by spatial light modulation, and circuitry for switching liquid crystal in the panel between having a first configuration in a first mode to cause an image displayed using the panel to be discernible from a wide range of viewing angles, and having a second configuration in a second mode to cause an image displayed using the panel to be discernible substantially only from within a narrow range of viewing angles. Several types of display panel to achieve such in-panel switching between public and private viewing modes are disclosed.
