Disclosed are an array substrate, a display panel, a display device, and a driving method. The array substrate includes a plurality of data lines, and a plurality of columns of pixel structures which are respectively connected to the plurality of data lines in one-to-one correspondence. Each of the plurality of columns of the pixel structures includes a plurality of pixel structures. Each of the plurality of pixel structures includes two adjacent sub-pixel units and a first transistor. The sub-pixel unit includes a second transistor. The first transistor is connected to the second transistors of the two adjacent sub-pixel units and the data line respectively.
