Abstract: A display device includes a plurality of pixels arranged in a column direction and a row direction, a plurality of data lines and a data driving part configured to apply data signals to the data lines. The data lines are connected with one of the pixels of a k-th column (‘k’ is a natural number) and one of the pixels of a (k+1)-th column in an odd-numbered row. The data lines are connected with one of the pixels of a (k+1)-th column and one of the pixels of a (k+2)-th column in an even-numbered row. As a result, a pseudo dot inversion drive pattern may be implemented while driving the data lines in accordance with a columnar polarity inversion scheme.

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.
