Claim:
1. A gate pulse modulation waveform-shaping circuit comprising: an input terminal for receiving a control signal; an output pair connected to a scan line for outputting a gate output voltage; and a gate pulse modulation waveform-shaping control circuit connected to the output pair, wherein the gate pulse modulation waveform-shaping control circuit is based on the control signal to use a time interval or a fixed discharge voltage to generate a delay for adjusting a discharge slope thereby generating different discharge time on the scan line, so that the gate output voltage has a voltage waveform, the voltage waveform including a plurality of waveform segments, the voltage waveform including at least two of the waveform segments each with a non-zero sliding slope and at least two of the waveform segments each with a zero slope.
