    摘要： The present application discloses a pixel array substrate. The pixel array substrate includes a plurality of pixels arranged in an array having multiple data-input terminals. N columns of subpixels per each column of pixels are associated with N sets of M numbers of data lines. N is an integer equal to and greater than 1 and M is an even number equal to or greater than 2. The pixel array substrate also includes N sets of M numbers of switches coupled respectively to the N sets of M numbers of data lines. Control terminals of each set of M numbers of switches are respectively coupled to M numbers of clock-signal terminals to receive respective clock control signals to control M groups of subpixels in each corresponding one column of subpixels for connecting with one of the multiple data-input terminals respectively via each corresponding set of M numbers of data lines.
