  • Publication number: 20090085849
    Abstract: A driving method for a liquid crystal display (LCD) panel is provided. The method comprises applying corresponding overdriving data for source data to the LCD panel at the beginning of a frame; applying black data to the LCD panel before the end of the frame, wherein the polarities of the applied black data are the same as the pixel electrode driving polarity at the beginning of a next frame; and applying the source data to the LCD panel at a time between the application of the overdriving data and the application of the black data. The driving method of the invention eliminates the need for large TFTs by reducing the voltage change between the end of a previous frame and the beginning of a current frame, and also can perform pre-charging for the pixel electrodes without adding any other device.
