摘要： A method for generating data for driving a display panel is provided in which first compensation data of (N+k) bits, corresponding to grayscale data of N bits, is generated, wherein values of N and k are natural numbers. A first gamma curve is applied to the first compensation data of (N+k) bits. Second compensation data of (N+k) bits, corresponding to the grayscale data of N bits, is generated. A second gamma curve is applied to the second compensation data of (N+k) bits. The first compensation data or the second compensation data are selectively output and converted into analog data signals. The analog data signals are output to a data line. Accordingly, the first compensation data and second compensation data includes a multidomain structure which improves display quality. A data driving circuit and a display device including the data driving circuit for performing the method are also provided.

摘要： A signal processing device includes a memory in which a color correction data is stored. The memory stores a first color correction data having the same number of bits as an input image data and a second color correction data having fewer number of bits than the input image data. The number of color correction data corresponding to a low gray-scale range increases and the number of color correction data corresponding to a high gray-scale range decreases by the same amount that the number of the color correction data corresponding to the low gray-scale range increased. Thus, a color characteristic corresponding to the low gray-scale range may be improved without changing the total number of color correction data.

摘要： A liquid crystal display system including a signal processing device uses interpolation to generate an intermediate image frame using previous image frame data and present image frame data. The system converts data of the intermediate image frame into transposed image data that is to be used to drive a liquid crystal display panel and display a corresponding image. The transposed image data and the present image data are subjected to a prespecified DCC process (dynamic capacitance compensation process) to thereby generate respective first and second compensation image data. Since the first compensation image data is generated based on the transposed image data and the transposition is configured to prevent over-compensation by the DCC process, over-compensation by the dynamic capacitance compensation process can be reduced or prevented.

摘要： A liquid crystal display includes a timing controller and a liquid crystal panel. The timing controller sequentially receives first through third primitive image signals and sequentially outputs first through third corrected image signals. The liquid crystal panel displays an image based on the first through third corrected image signals. The timing controller generates a first converted image signal having a first gray level based on the first primitive image signal and stores the first converted image signal. The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.
