The clock transmission wires are configured to transmit clock signals having different phases. Each of the driving circuits has a clock input terminal, a pre-charge terminal, a discharge control terminal and an output terminal. The output terminals are configured to drive gate lines of a display panel. The driving circuits are grouped into several driving circuit groups. The driving circuits belonging to a first driving circuit group among the driving circuit groups are called first driving circuits. The clock input terminals of the first driving circuits are coupled to different transmission wires among the clock transmission wires. The pre-charge terminals of the first driving circuits commonly receive a first pre-charge signal.
