Abstract:
1. A method for driving a liquid crystal display panel, wherein the liquid crystal display panel has a plurality of pixels arranged in a matrix form and a plurality of data lines, the method comprising: generating gray level signals corresponding to the plurality of pixels according to input image data; determining whether gray level values of pixels in the same row corresponding to the plurality of data lines of a first color are all outside a first range; when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the first color are all outside the first range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the first color to be in a first inversion mode, and when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the first color are not all outside the first range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the first color to be in a second inversion mode; determining whether gray level values of pixels in the same row corresponding to the plurality of data lines of a second color are all outside a second range; when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the second color are all outside the second range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the second color to be in the first inversion mode, and when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the second color are not all outside the second range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the second color to be in the second inversion mode; determining whether gray level values of pixels in the same row corresponding to the plurality of data lines of a third color are all outside a third range; and when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the third color are all outside the third range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the second color to be in the first inversion mode, and when the gray level values of the pixels in the same row corresponding to the plurality of data lines of the third color are not all outside the third range, controlling polarity of the gray level signals of the pixels in the same row corresponding to the plurality of data lines of the third color to be in the second inversion mode; wherein the first color is red, the second color is green, and the third color is blue, a maximum value of the first range is less than a maximum value of the third range and less than a maximum value of the second range, and a minimum value of the first range is greater than a minimum value of the third range and greater than a minimum value of the second range.
