Abstract: A display panel apparatus includes a display panel and a timing controller, and a data driver. The display panel includes a first subpixel and a second subpixel. The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel. When the second subpixel is determined to be defective, the timing controller generates a compensated grayscale of the second subpixel data. The data driver is configured to apply a precharge voltage to the second subpixel and a charging voltage to second subpixel through a data line, wherein the precharge voltage is based on a grayscale of the first subpixel data and the charging voltage is based on the compensated grayscale of the second subpixel data.

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.
