Abstract: The present invention provides a display device driving method, a display device. The method achieves dynamic adjustment of a brightness of light emission of backlight units according to display contents corresponding to the display units. Also, conversion of a bit width of a drive voltage value is implemented based on a drive voltage conversion relationship table between first bit width drive voltage values and second bit width drive voltage values of the brightness values, which improves the driving effect of the backlight module.

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.
