Abstract: A gate drive circuit and a display panel. The gate drive circuit includes multi-stage cascaded gate drive units. The gate drive units each include a pull-up control module, an output module, a pull-down module, a pull-down maintain module, a first reference low-level signal input terminal, a second reference low-level signal input terminal, and a pull-up node located in a line between the pull-up control module and the output module. The pull-up control module includes a pull-up control transistor that is electrically connected to the pull-up node and configured to pull a potential of the pull-up node up. The output module includes a scan signal output transistor that is electrically connected to the pull-up node and configured to output a present-stage scan signal under control of the potential of the pull-up node.

Abstract: A display screen and a display device are provided. The display screen includes a display panel assembly, a light bar, and a reflective layer. The display panel assembly includes at least two display panels with a splicing gap between each two display panels. The light bar is attached to a display surface of the display panel assembly, covers the splicing gap, and has two opposite side surfaces extending along a length of the splicing gap. At least one side surface of the light bar is provided with the reflective layer to prevent black borders from appearing on the side surfaces of the light bar.

Abstract: A backlight driving method and a display panel are provided. The backlight driving method provided by the present application uses pulse width modulation technology to modulate a low-level pulse width of a scan signal. By increasing a low-level pulse width to increase the pulse period, a number of high-level pulses is reduced, thereby reducing a high-level pulse time. Therefore, a time for a TFT to receive a high-level voltage is also reduced, thereby improving a stability of the TFT and also improving a problem of a threshold voltage drift of the TFT.
