摘要： The present disclosure provides a display drive circuit for driving a display panel having a plurality of pixels. The display drive circuit comprises a stepping unit, configured to shape a gate voltage signal to compensate for pixel-to-pixel charging variations to thereby reduce luminance variations on the display panel. The display drive circuit can further include a time sequence control unit and a modulation unit. The time sequence control unit can be coupled to the modulation unit, and can be configured to generate a first control signal; and the modulation unit can be configured to utilize the first control signal to modulate a preset signal to thereby generate a second control signal; and the stepping unit can be coupled to the modulation unit, and can be configured to shape the gate voltage signal based on the second control signal prior to outputting the gate voltage signal.
