  • Patent number: 10726805
    Abstract: A display driving apparatus applied to a panel is disclosed. The panel displays a first image with a first refresh rate. A first refresh cycle corresponding to the first refresh rate includes a refresh period and at least one non-refresh period. The display driving apparatus includes a real-time determination module and a data processing module. The real-time determination module is coupled to the panel and used to immediately determine whether the panel wants to replace the originally displayed first image with a second image during the first refresh cycle. The data processing module is coupled to the real-time determination module and the panel. If a determination result of the real-time determination module is yes, the data processing module immediately controls the panel to start to display the second image at a first time during the first refresh cycle.

  • Patent number: 8902203
    Abstract: A liquid crystal display comprises a power supply, a pulse adjustment circuit, and a gate driver. The pulse adjustment circuit is connected between the power supply and the gate driver. The power supply provides power signals. The pulse adjustment circuit adjusts the plurality of pulses of the power signals or selects the appropriate voltage levels for the power signals to have cutting angles or enlarged amplitudes, whereby the influence of the feedthrough voltage on the thin film transistors of the driving circuit would be reduced so that the display quality of the liquid crystal display is improved.

  • Patent number: 8502764
    Abstract: A gate driving method for a liquid crystal display (LCD) and a gate driver thereof are provided. The LCD has a plurality of scan lines. The method starts by generating a gate driving signal. A correction signal is superposed to the gate driving signal to generate a corrected gate driving signal and to reduce a high voltage level of the gate driving signal, wherein a polarity of the correction signal is opposite to a polarity of the gate driving signal. The corrected gate driving signal is then outputted to drive one of the corresponding scan lines.
