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.

Abstract: The present application discloses a backlight module and a display device. The present application disposes a supporting portion, configured to support the diffuser plate, on a bottom board of a backplate. The supporting portion needs no connection with a light emitting diode (LED) lamp board. Compared to a conventional backlight module using a structure of a support bracket connected to an LED lamp board, the supporting portion of the present application can be formed during manufacturing the bottom board of the backplate to reduce fabrication processes of the backlight module and lower installation difficulty and a cost.
