Abstract:
1. A TFT-LCD array substrate, comprising a substrate, on which pixel regions arranged in matrix are formed, wherein a first pixel electrode and a first thin film transistor located in an odd column and a second pixel electrode and a second thin film transistor located in an even column are formed in each pixel region, drain of the first thin film transistor is connected to the first pixel electrode, and drain of the second thin film transistor is connected to the second pixel electrode, wherein, a first gate line and a second gate line are formed in each pixel region, the first gate line is connected to gate of the first thin film transistor, and the second gate line is connected to gate of the second thin film transistor; one data line is formed in each pixel region, and the data line is connected to source of the first thin film transistor and source of the second thin film transistor, respectively, wherein, a selection switching device is further set on the substrate, for receiving a scan driving circuit signal, generating a row scan signal, and outputting the row scan signal to the first gate line and the second gate line in turn, and wherein, the selection switching device comprises a first selection switching device located at one end of the first gate line and the second gate line, which transmits the row scan signal to the first gate line and the second gate line in turn; and a second selection switching device located at the other end of the first gate line and the second gate line, which transmits the row scan signal to the first gate line and the second gate line in turn.
