Abstract: The embodiments of the present application provided a backlight module and a display panel. By disposing a reflective layer on the substrate and disposing vias, whose areas gradually decrease from the side close to an electric current input side to the side away from the electric current input side, on the reflective layer, the backlight module reduces the brightness of a light emitting device layer close to the electric current input side and increase the brightness of the light emitting device layer away from the electric current input side. Thus the brightness of both sides of the light emitting devise layer is uniform, and thus the backlight uniformity of the backlight module is increased.

Abstract: A display device driving method and the display device are provided. The display device driving method determines a driving voltage value of each backlight unit based on a content to be displayed by a display unit corresponding to each backlight unit, achieving dynamic adjustment of luminous brightness of the backlight unit according to the display content of the corresponding display unit. Meanwhile, the driving voltage value is related to a noise in an image. Therefore, a better backlight brightness value can be obtained by reducing an influence of the noise on the adjustment of the luminous brightness.
