Discharging circuit and driving method thereof, display device

A driving method of a discharging circuit, comprising:

• at a start-up stage, pulling down, by a control circuit, potential of a first node-, so as to switch on a first discharging circuit to pull down a potential of a data signal terminal to a potential of a common voltage terminal;
• delaying, by a time delay circuit, switch-on of a second discharging circuit, so as to release the potential of the common voltage terminal and the potential of the data signal terminal;
• meanwhile, charging a first voltage stabilizing circuit, a second voltage stabilizing circuit and the time delay circuit;
• at a display stage, promoting, by the control circuit, potential of the first node, so as to switch off the first discharging circuit and the second discharging circuit to cause the data signal terminal, the common voltage terminal and a fifth signal terminal to be disconnected from one another;
• and
• at a shutdown stage, under control of a first voltage stabilizing circuit and a second voltage stabilizing circuit, pulling down, by the control circuit, a potential of the first node, so as to switch on the first discharging circuit to pull down the potential of the data signal terminal to the potential of the common voltage terminal;
• delaying, by the time delay circuit, switch-on of the second discharging circuit, so as to release the potential of the common voltage terminal and the potential of the data signal terminal.
