1. An output driving circuit, comprising:
a signal input terminal inputting a positive input signal and a negative input signal complementary to each other;
a pull-up output unit connected to the signal input terminal, the positive input signal acting as an input signal of the pull-up output unit;
a pull-down output unit connected to the signal input terminal, the negative input signal acting as an input signal of the pull-down output unit;
at least one compensation unit connected in parallel with the pull-up output unit or the pull-down output unit;
at least one pulse signal generation circuit having an input terminal connected to the signal input terminal, and generating a pulse signal based on the positive input signal or the negative input signal, the pulse signal acting as a control signal of the compensation unit; and
a signal output terminal connected to an output terminal of the pull-up output unit, an output terminal of the pull-down output unit and an output terminal of the compensation unit, and outputting an output signal;
wherein the output driving circuit further comprises a pull-up pre-amplification unit and a pull-down pre-amplification unit; the pull-up pre-amplification unit comprises a first terminal and a second terminal, the first terminal of the pull-up pre-amplification unit is connected to the positive input signal, and the second terminal of the pull-up pre-amplification unit is connected to a control terminal of the pull-up output unit; the pull-down pre-amplification unit comprises a first terminal and a second terminal, the first terminal of the pull-down pre-amplification unit is connected to the negative input signal, the second terminal of the pull-down pre-amplification unit is connected to a control terminal of the pull-down output unit, and the input terminal of the pulse signal generation circuit is connected to the second terminal of the pull-up pre-amplification unit or the second terminal of the pull-down pre-amplification unit.
