20100066960 | LIQUID CRYSTAL DEVICE AND DISPLAY APPARATUS - 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. | 03-18-2010 |

20110261093 | ADAPTIVE IMAGE PROCESSING METHOD AND APPARATUS FOR REDUCED COLOUR SHIFT IN LCDs - A method and apparatus is provided for reducing colour 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 colour components having respective data values; for each of the pixel data, comparing the sub-pixel colour component data values included therein; and based on the comparison, modifying the sub-pixel colour component data values included in the pixel data with respect to two or more of the plurality of sub-pixel colour components to reduce colour shift when displayed on the LCD. | 10-27-2011 |
20120154458 | APPARATUS, DISPLAY DEVICE, PROGRAM AND METHOD THEREOF FOR PROCESSING IMAGE DATA FOR DISPLAY BY A DISPLAY PANEL - 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. | 06-21-2012 |
20120169790 | APPARATUS, DISPLAY DEVICE, METHOD, PROGRAM, STORAGE MEDIUM AND LOOKUP TABLE FOR OPERATING A DISPLAY DEVICE COMPRISING A DISPLAY PANEL - A method of operating a display device comprising a display panel comprises receiving main and side image pixel data respectively representing a main image (S | 07-05-2012 |
20120176404 | METHOD, APPARATUS AND PROGRAM FOR PROCESSING IMAGE DATA FOR DISPLAY BY A DISPLAY PANEL OF A DISPLAY DEVICE, AND A DISPLAY DEVICE - A method is provided 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. | 07-12-2012 |
20130088528 | IMAGE PROCESSING METHOD FOR REDUCED COLOUR SHIFT IN MULTI-PRIMARY LCDs - A method of processing an image comprises: receiving pixel data constituting an image, the pixel data including at least four sub-pixel colour components having respective data values, and modifying one or more of the sub-pixel colour component data values. The data values of corresponding sub-pixels from two pixels are modified in opposite directions to one another and such that the overall luminance of the display panel appears substantially unchanged to an on-axis viewer of the display panel. | 04-11-2013 |

20150042769 | IMAGE PROCESSING FOR PRIVACY AND WIDE-VIEW USING ERROR DIFFUSION - A display device includes control electronics and a pixellated liquid crystal (LC) panel. The control electronics receives inputs of main image data for a main image and side image data for a side image. The control electronics outputs combined image data combining the main and side images such that an on-axis viewer perceives from the combined image the main image, and an off-axis viewer perceives from the combined image the side image. The output image data comprises data values chosen from a set of available output data values for the pixels selected from multiple sets of available data values depending on at least on the side image data. For a pixel currently being processed, the output data value is chosen from the selected set of available output data values for which a resulting luminance value is closest to a target luminance value for the current pixel. | 02-12-2015 |
