    摘要： A display device is provided that comprises a liquid crystal display panel (2) for displaying an image by spatial light modulation. The image is represented by a plurality of image elements each having an image data value (7). The display device further comprises a display controller (1) arranged to determine a signal voltage to be applied to the panel (2) for each image element in dependence upon its image data value (7) and a secondary data value (8) for the element, there being a predetermined mapping between the data values and the signal voltage. The secondary data values (8) are arranged to vary across the image so as to introduce variations in luminance as a result of the mapping. The mapping and secondary data values (8) are mutually arranged to take account of the signal voltage to on-axis luminance response of the panel (2) so that the luminance variations introduced on-axis tend to balance locally through spatial averaging to, and hence would not be perceivable by, an on-axis viewer (3). The panel (2) furthermore has a non-linear off-axis luminance to on-axis luminance relationship, so that at least some of the luminance variations introduced off-axis do not balance locally through spatial averaging to, and hence would be perceivable by, an off-axis viewer (4).

    摘要： A method of processing image data for display by a display panel of a display device is provided. The method comprises receiving main image pixel data representing a main and side image pixel data representing a side image. In a first processing step, a mapping is performed 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. In a second processing step, the received side image pixel data are processed to emphasise at least one feature of the side image which might otherwise be perceived by a viewer as being de-emphasised in the side image displayed off axis as a result of the first processing step.

    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.
