  • Patent number: 8766894
    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.

  • Patent number: 8552947
    Abstract: In a driving device and a display apparatus having the driving device, a converter converts input image data and outputs first and second sub-image data which have different values. A first compensator compensates the first sub-image data and outputs a first compensated image data, and a second compensator compensates the second sub-image data and outputs a second compensated image data. An output circuit controls output time of the first and second compensated image data. Accordingly, sub-image data for each sub-pixel may be exactly compensated by employing compensators to individually compensate for the sub-image data of each sub-pixel.
