1. A display panel, comprising:
a plurality of sub-pixels arranged in a matrix, wherein the sub-pixels are grouped into a plurality of cell areas arranged repeatedly in rows and columns, each cell area comprises at least a first sub-pixel and at least a second sub-pixel adjacent to the first sub-pixel;
a plurality of scanlines, transmitting scan signals to each sub-pixel, wherein each row of the sub-pixels corresponds to one of the scanlines; and
a plurality of data lines, transmitting data signals to each sub-pixel, wherein at least one data line is arranged between two adjacent columns of sub-pixels; wherein:
polarities of adjacent sub-pixels in each cell area are opposite, polarity of each of sub-pixels is positive or negative; and
wherein during one display cycle, in each cell area:
a gray-level of the first sub-pixel is switched in an order of high, high, low, and low, the first sub-pixel renders brightness in the first and second frames greater than a first target brightness of the first sub-pixel, and the first sub-pixel renders brightness in the third and fourth frames lower than the first target brightness of the first sub-pixel; and
a gray-level of the second sub-pixel is switched in an order of low, low, high, and high, the second sub-pixel renders brightness in the first and second frames lower than a second target display brightness of the second sub-pixel, and the second sub-pixel renders brightness in the third and fourth frames greater than the second target display brightness of the second sub-pixel.
