    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 display comprises a parallax optic (2), such as a combined parallax barrier and lens array, and a pixellated display device (1). The pixels of the display device (1) are arranged as groups cooperating with a parallax element (4) of the parallax optic (2). Each group comprises a first pixel (A) aligned with the centre of the parallax element (4), second and third pixels (B, C) on either side of the first pixel (A), and fourth pixels (D) shared with adjacent groups and disposed outside the second pixels (B, C). The parallax elements (4) make the different pixels of each group visible in different viewing regions. A control arrangement selects regions of the display and selects different combinations of the pixels of each group for image display within respective regions so as to provide simultaneously-present different viewing modes having different viewing range characteristics.
