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: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A light absorbing layer is arranged in the first gap between at least two adjacent light emitting elements. By arranging the light absorbing layer, the side light of the light emitting elements can be partially absorbed, thereby reducing an emission angle of the light bar.
