    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: A driving unit of display panel includes a data driving part, a timing controlling part and a gate driving part. The data driving part is configured to receive reference image data and includes a first data driving circuit part having a first channel outputting a first reference data signal based on the reference image data and a k-th channel outputting a k-th reference data signal based on the reference image data. The timing controlling part is configured to detect a time difference between the first reference data signal and the k-th reference data signal. The gate driving part is configured to output a gate signal to each of gate lines. By delaying data signals based on the gate signal delay caused by long line load and RC delay, the present invention may improve display quality of a display device.
