  • Patent number: 8866808
    Abstract: A method for driving a display panel is provided. The method includes the following steps. Firstly, providing a first scan signal to turn on a plurality of first sub-pixels within the ith pixel row of the display panel during a Nth frame period, so as to make the first sub-pixels respectively receive a corresponding first data signal. Next, providing a second scan signal to turn on a plurality of second sub-pixels within the ith pixel row of the display panel during the Nth frame period, so as to make the second sub-pixels respectively receive a corresponding second data signal. The amplitude of the first scan signal is different from the amplitude of the second scan signal, and N and i are positive integers.

  • Publication number: 20120176352
    Abstract: A driving method for driving a display panel is provided. The display panel includes a plurality of scan lines, a plurality of data lines, and a plurality of pixel units electrically connected to the scan lines and the data lines. The driving method comprises enabling the pixel units controlled by the scan lines through different scanning sequences and inputs image data to the pixel units via the data lines in several consecutive frame times, wherein capacitance coupling effects between the pixel units are varied depending on the scanning sequences. Accordingly, the line mura caused by the capacitance coupling effect is restrained.

  • Publication number: 20100085291
    Abstract: An LCD with two-dot inversion includes plural gate lines for transmitting gate driving signals, plural data lines for transmitting data driving signals, and a pixel array. The pixel array includes plural pixels. The plural pixels display frames according to the received gate driving signals and data driving signals. A first data line of the plural data lines is coupled to a first column of pixels and a second column of pixels. The plural data lines are curves with several bends. The difference between the numbers of the first and the second columns is at least two.
