Abstract: The present disclosure provides a pixel structure, a method of driving the same and a display device. The pixel structure includes gate lines, data lines, and a plurality of subpixels arranged in an array form. Subpixels in each row correspond to two gate lines. Each data line corresponds to the subpixels in two adjacent columns, and each data line is arranged between the two adjacent columns of subpixels. Among the subpixels in each row, three adjacent subpixels are in different colors and forms a complete pixel unit. Among the subpixels in each column, three adjacent subpixels are in different colors and forms the complete pixel unit. Among the subpixels in two adjacent columns, the subpixels in two adjacent rows form two complete pixel units each including three subpixels, and two of the three subpixels are shared by the two pixel unit.
