    Abstract: The present disclosure provides a pixel array and a fabrication method thereof. The pixel array includes a plurality of gate lines and a plurality of data lines which are arranged intersected and insulated and a pixel unit disposed at a position where each of the plurality of gate lines and each of the plurality of data lines are intersected. The pixel unit includes a thin film transistor (TFT). The width-to-length ratios of channels of the TFTs are sequentially increased in such a manner that the width-to-length ratios of the channels of the TFTs in the pixel units positioned in a same row (and/or a same column) are sequentially increased along a scanning direction of the gate line coupled to gate electrodes of the TFTs in the same row (and/or along a data writing direction of the data line coupled to the source electrodes of the TFTs in the same column).

    IPC: G09G3/36

    Abstract: A driving method is provided to drive an LCD panel having rows of pixels includes obtaining source data signals of a plurality of frames for the LCD panel; inputting a source data signal of one frame of the plurality of frames; and inverting polarity of the source data signal of the one frame before scanning sequentially the rows of pixels. The driving method also includes configuring at least one of timing of the source data signal and timing of scanning a first row of the rows of pixels to cause a time overlap between an actual scanning time of the first row and a time period when the source data signal is at a threshold value to be no less than an original scanning time of the first row; scanning the first row of the rows of pixels; and scanning rest of the rows of pixels to complete displaying the one frame.
