An array substrate including a plurality of pixel units arranged in a matrix is provided. Each pixel unit at least includes a first sub-pixel, a second sub-pixel and a third sub-pixel that emit light of different colors, the first sub-pixel has a lower luminous efficiency than the second and third sub-pixels. The array substrate further comprises a plurality of first gate lines and a plurality of second gate lines that correspond to respective rows of pixel units of the plurality of pixel units. The first sub-pixel in each row of pixel units of the plurality of pixel units is coupled to a first gate line of the plurality of first gate lines, and the second sub-pixel and the third sub-pixel in the row of pixel units of the plurality of pixel units are both coupled to a second gate line of the plurality of second gate lines.
