Abstract: A data driver includes a digital-to-analog converter, a control signal output circuit, and an output buffer. The digital-to-analog converter generates first data voltages and second data voltages based on image data and a polarity control signal. Each first data voltage has a positive polarity, and each second data voltage has a negative polarity. The control signal output circuit outputs a first output control signal and a second output control signal based on the polarity control signal. A phase of the second output control signal is different from a phase of the first output control signal. The output buffer outputs the first data voltages based on the first output control signal and outputs the second data voltages based on the second output control signal.

Abstract: 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.

Abstract: An adaptive black clipping circuit in a display device includes a data corrector, a register, a pattern detector and a clipping selector. The data corrects input image data to generate corrected image data such that the corrected image data is equal to or greater than a black clipping value where the black clipping value corresponds to the input image data having a grayscale value of zero and the black clipping value is greater than zero. The register stores and provides configuration data. The pattern detector generates a pattern detection signal based on the input image data corresponding to a plurality of rows. The clipping selector selects one of the corrected image data and the configuration data in response to the pattern detection signal to provide output image data.

Abstract: 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.
