Abstract
A compensation circuitry of gate driving pulse signal is adapted to receive a gate driving pulse signal and includes a pre-processing circuit, a peak detector, a discharge circuit, 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 thereof. The pre-processed gate driving pulse signal then is transmitted to the peak detector for obtaining a peak voltage after a charging operation, and also is transmitted to the discharge circuit to determine whether to enable the discharge circuit so that providing the peak detector with a discharge loop when the discharge circuit 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 peak voltage. A display device using the above compensation circuitry also is provided.
