Claim:
A method for driving a liquid crystal panel, the liquid crystal panel comprising a plurality of sub-pixel units, the sub-pixel units comprising sub-pixel units of a first color, sub-pixel units of a second color, and sub-pixel units of a third color arranged in a regular, repeating array, each three adjacent sub-pixel units having the first color, the second color, and the third color defining a pixel, the method comprising: defining the array of pixels as comprising an array of dithering units, each dithering unit comprising a same plurality of pixels; providing a predetermined inversion driving pattern for each dithering unit, wherein a polarity of each sub-pixel unit of the dithering unit is reversed at least once, and the completion of the at least one reversal of every sub-pixel unit defines a cycle of the inversion driving pattern; providing a series of predetermined dithering patterns for each dithering unit, wherein each dithering unit is capable of displaying at least two predetermined gray scales, and the series of predetermined dithering patterns defines a cycle of dithering patterns; driving the sub-pixel units according to a sequence of frames, a predetermined plurality of the sequential frames defining a cycle of frames, wherein in each cycle of frames, the polarity of each sub-pixel unit of each dithering unit is reversed according to the cycle of the inversion driving pattern, and the pixels of each dithering unit are dithered according to the cycle of dithering patterns, wherein in each frame, each row and each column of sub-pixel units in the array of pixels has a pattern of positive and negative polarities, and both the polarities of the sub-pixels at rows and the polarities of sub-pixels at columns are changed according to a 1-2 line driving method, wherein according to any three adjacent rows of sub-pixel units, one row of sub-pixel units adjacent to the middle row of sub-pixel units has a same pattern of positive and negative polarities with the middle row of sub-pixel units, the other row of the sub-pixel units adjacent to the middle row of sub-pixel units has a pattern of positive and negative polarities reversed to the pattern of positive and negative polarities of the middle row of sub-pixel units, at the same time, according to any three adjacent columns of sub-pixel units, one column of sub-pixel units adjacent to the middle column of sub-pixel units has a same pattern of positive and negative polarities with the middle column of sub-pixel units, the other column of sub-pixel units adjacent to the middle column of sub-pixel units has a pattern of positive and negative polarities reversed to the pattern of positive and negative polarities of the middle column of sub-pixel units, and the polarity of each sub-pixel unit in the array of pixels is reversed at each frame.
