The disclosure relates to a pixel driving method, a gate driver, and a display device. The pixel driving method comprises: generating a first scanning signal and supplying the first scanning signal to a first sub-pixel row; generating a second scanning signal and supplying the second scanning signal to a second sub-pixel row, wherein the amplitude of the generated first scanning signal and the amplitude of the second scanning signal cause a difference between the step voltage of the first sub-pixel row and the step voltage of the second sub-pixel row to be less than a preset value. The method can improve the display panel flicker caused by the difference in the parasitic capacitance of the transistors, thereby improving the display effect.
