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.

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： A switchable imaging device (1) has a first mode of operation in which the device performs an imaging function and a second mode of operation different from the first mode, for example a non-imaging mode. In the first mode of operation the device comprises at least one first region that performs a lensing action and at least one second region that at least partially absorbs light passing through the or each second region. The switchable imaging device (1) may be disposed in path of light through an image display panel (4). This provides a display that may be operable in either a directional display mode such as an autostereoscopic 3D display mode or a 2-D display mode, by controlling the switchable imaging device to be in its first mode or its second mode.

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 a first alignment surface which induces a high pretilt greater than 45° but less than 90°; a typical value is 85°. The pretilt has a component parallel to the surface pointing in a predetermined direction. A second alignment surface induces a low pretilt which is less than 45° but greater than 0°; a typical pretilt is 5°. The low pretilt has a component parallel to the second surface which also points in the predetermined direction. A layer of crystal material is disposed in between the first and second surfaces. A novel liquid crystal mode is thus provided and is referred to as the “splay-twist mode”. Such a device may be used in a switchable public/private display.
