    摘要: An image is updated on a bi-stable display (310) such as an electrophoretic display by providing separate scaling functions (SF1, SF2) for scaling a duration of a reset pulse (R) and a duration of a driving pulse (D) in a drive waveform based on temperature (335). An absolute value of a slope with varying temperatures of the scaling factor (SF1) for the reset pulse (R) is significantly greater than that of the scaling factor (SF2) for the driving pulse (D), while both scaling factors increase with decreasing temperature. Image update time (IUT) is significantly reduced at lower temperatures, while a range of variation of IUT across all temperatures is also reduced. Scaling functions (SF3, SF4) may also be used for scaling a duration of a help reset pulse (H) and/or a duration of one or more shaking pulses (SH1, SH2).

    摘要: Driver circuitry of each pixel provides pixel drive currents to respective LED display elements of the pixels of a display. An output transistor arrangement for each column drive circuit within a pixel has a plurality of output transistors (70, 72, 74) in parallel, and one or more of these are selected in order to provide desired output characteristics. Thus, the output of each column drive circuit can be tuned to provide desired output characteristics. In order to select an output transistor, fusible links of non selected transistors may be broken, or further transistors may connect selected transistors to a gate control line while non-selected transistors are connected to a de-select line.

    摘要: 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.
