  • Publication number: 20120249405
    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: 8194029
    Abstract: A display device includes a driving signal generator being supplied with a synchronous signal and a clock signal and generating an inverter driving signal having a given frequency that is multiplied by a predetermined ratio from a frequency of the synchronous signal, an inverter outputting a driving signal based on the inverter driving signal, and a backlight unit controlling turned-on or turned-off based on the driving signal from the inverter. The driving signal generator operates the number of clocks of the clock signal included in a predetermined period of the synchronous signal by using a predetermined value, defines a magnitude of each section of the inverter driving signal with respect to the predetermined period of the synchronous signal, and adjusts the section magnitude of the inverter driving signal when the number of clocks differs from the total section magnitude of the inverter driving signal based on the magnitude of each section.

  • Publication number: 20120081410
    Abstract: Rather than using complex zigzag patterns or the like for counter-compensating for the different lengths of fanout lines used to transmit data line drive voltages from more concentrated source points of the drive voltages to more spread apart data lines of a given display panel, digital data signals that represent the to be output data line drive voltages are automatically adjusted so that the data line drive voltages output from the concentrated source points are pre-adjusted to counter voltage drop difference effects that will be applied to those pre-adjusted data line drive voltages by the difference of resistances among the fanout lines of different lengths.

  • Publication number: 20110316900
    Abstract: A display apparatus includes a display panel, a gate driver, a gray scale compensator, and a date driver. The gate driver sequentially applies gate data to the gate lines. The gray scale compensator compares the primitive gray scale data of the n-th frame with the primitive gray scale data of the (n?1)-th frame to output a compensated gray scale data of a n-th frame, when a primitive gray scale data of a (n?1)-th frame is lower than a gray scale data of a first gray scale and a primitive gray scale data of the n-th frame is higher than a gray scale data of a second gray scale. The date driver converts the compensated gray scale data into a date voltage corresponding to the compensated gray scale data and applies the data voltage to the date line. Therefore, response time of the liquid crystal molecules may be reduced.

  • Publication number: 20090309903
    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.
