a plurality of scan lines arranged in a first direction;

a plurality of data lines arranged in a second direction, the second direction being perpendicular to the first direction; and

a plurality of pixel units arranged in an array, wherein each of the plurality of pixel units comprises a red sub-pixel, a green sub-pixel, and a blue sub-pixel, a plurality of sub-pixels are arranged in rows in the first direction, sub-pixels in each of the rows are coupled with one of the plurality of scan lines to receive a scan signal, sub-pixels which emit lights of a same color are arranged in columns in the second direction, and sub-pixels in each of the columns are coupled with at least one of the plurality of data lines to receive image display data; wherein

the blue sub-pixel has a charging rate higher than each of the red sub-pixel and the green sub-pixel, in any pixel unit of the array;

a plurality of blue sub-pixels in any column are coupled with two data lines, to receive the image display data from the two data lines when the plurality of blue sub-pixels are started by the scan signal; and

the plurality of blue sub-pixels in any column comprises a first blue sub-pixel to a n-th blue sub-pixel which are arranged in sequence, wherein the first blue sub-pixel to an i-th blue sub-pixel are coupled with one of the two data lines, and an (i+1)-th blue sub-pixel to the n-th blue sub-pixel are coupled with another of the two data lines, i being greater than 1.
