Zusammenfassung:The present invention relates to a compensation circuit of gate driving pulse signal adapted to receive a gate driving pulse signal generated in a frequency period of a gate driving circuit. The compensation circuit includes a pre-processing circuit, a peak detector, a charge releaser, a voltage buffer and a charge pump circuit. The pre-preprocessing circuit performs a pre-processing operation to the gate driving pulse signal to adjust a voltage of the gate driving pulse signal. The pre-processed gate driving pulse signal then is transmitted to the peak detector for obtaining a peak voltage after a charging operation. The pre-processed gate driving pulse signal also is transmitted to the charge releaser to determine whether to enable the charge releaser so that providing the peak detector with a charge releasing loop when the charge releaser is enabled. The charge pump circuit acquires the peak voltage through the voltage buffer and then modulates a waveform of the gate driving pulse signal according to the p
