Claim Text:
1. A pixel driving circuit, characterized in that, it comprises a reset module, a data write module, an output module and a pre-charging module, wherein the reset module is connected to a first signal input terminal, a reset voltage and a control node, and is used for resetting potential of the control node in accordance with a signal inputted from the first signal input terminal, the data write module is connected to a gate line, a data input terminal, the control node and the output module, and is used for storing a data signal inputted from the data input terminal to the control node as a voltage when a row driving signal is inputted through the gate line, and the voltage stored at the control node is used for activating the output module, the output module is also connected to an emission signal input terminal, the control node and a light emitting device, and is used for supplying power to the light emitting device when a signal is inputted from the emission signal input terminal, the pre-charging module is connected to a second signal input terminal, the control node and the output module, and is used for pre-charging the control node after resetting is ended and before the row driving signal is inputted through the gate line.
