摘要： An array substrate, a display panel, a driving method thereof and a display device are provided. Each pixel in the array substrate includes four sub-pixels having different color filter colors and arranged in two rows and two columns. With respect to an example in which each row of sub-pixels corresponds to one gate line and each column of sub-pixels correspond to two data lines, during 3D display, two gate lines corresponding to each row of pixels apply gate scanning signals to this row of pixels, and two data lines corresponding to each column of sub-pixels apply gray scale signals to two sub-pixels belonging to each pixel in this column of sub-pixels respectively. Two sub-pixels having color filters of different colors belonging to a single pixel, in each column of sub-pixels, may receive gray scale signals over different data lines.
