An apparatus and method for driving a display panel. The display panel comprises a pixel circuit (1), a gate drive circuit (2) and a source drive circuit (3). The device for driving the display panel is configured to provide an invalid starting signal to the gate driving circuit (2) and/or the light-emitting control driving circuit (4) in a first time period; in the second time period, the first power supply signal and the second power supply signal are provided for the pixel circuit (1); and in the third time period, an effective starting signal is provided for the grid driving circuit (2) and/or the light-emitting control driving circuit (4). According to the device, an improved power-on and/or power-off time sequence is provided for the display panel, and the problems of display picture flickering or circuit short circuit and the like caused by the unstable state of an internal circuit of the display panel in the power-on and/or power-off process can be solved. 一种用于驱动显示面板的装置、方法。显示面板包括像素电路(1)、栅极驱动电路(2)、以及源极
