ABSTRACT:
A display device, for example a liquid crystal display device (1), and driving method are provided that avoid the need to provide the display device with display data (e.g. video) containing individual display settings for each pixel. The display device comprises an array of pixels (21-36, 71a-79d, 121-136) and an array of processing elements (41-48, 71-79, 141-148), each processing element being associated with a respective pixel or group of pixels. The processing elements (41-48, 71-79, 141-148) perform processing of compressed input display data at pixel level. The processing elements (41-48, 71-79, 141-148) decompress the input data to determine individual pixel settings for their associated pixel or pixels. The processing elements (41-48, 71-79, 141-148) then drive the pixels (21-36, 71a-79d, 121-136) at the individual settings. A processing element may interpolate pixel settings from input data allocated to itself and one or more neighbouring processing elements. Alternatively, the processing elements may have knowledge of the pixel locations of pixels associated with it, and use this information to determine whether one or more of its pixels needs to be driven in response to common input data received by the plural processing elements.
