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 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 operating a display device comprising a display panel comprises receiving main and side image pixel data respectively representing a main image (S1) and a side image (S2). For each of a plurality of pixel groups (S3), where each pixel group comprises at least one pixel of the main image pixel data and at least one spatially corresponding pixel of the side image pixel data, a predetermined mapping is performed (S4) using the pixel data of the pixel group as input. The mapping holds output pixel data for the input pixel data which is known to produce an average on-axis luminance with substantially no dependence on the side image pixel data of the group and an average off-axis luminance with substantially no dependence on the main image pixel data of the group. The signals used to drive the display panel are determined from the output pixel data (S5).

摘要： An image display apparatus having sub-pixels of four colors is provided in which the resolution when an image is two-dimensionally displayed is not affected, and deterioration in the color balance of a three-dimensionally displayed image is suppressed. In the image display apparatus, the arrangement of a sub-pixel for displaying red for a left eye and a sub-pixel for displaying green for a right eye has been replaced with the arrangement of a sub-pixel (Lg1) for displaying green for the left eye and a sub-pixel (Rr1) for displaying red for the right eye. The arrangement of a sub-pixel for displaying blue for the left eye and a sub-pixel for displaying yellow for the right eye has been replaced with the arrangement of a sub-pixel (Lx1) for displaying yellow for the left eye and a sub-pixel (Rb1) for displaying blue for the right eye. Replacement with the sub-pixel and the sub-pixel and replacement with the sub-pixel and the sub-pixel are made for every other pixel.

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.
