Backlight module and display module

The utility model provides a backlight module and a display module. The backlight module comprises a back plate, the back plate comprises a bottom wall and peripheral side walls, the peripheral side walls are arranged on the peripheral edges of the bottom wall in a surrounding mode, the lamp panel is located on one side of the bottom wall and located in a space defined by the bottom wall and the peripheral side walls, the lamp panel comprises a base material and a plurality of lamp beads located on one side face of the base material, and the lamp beads are arranged in an array. The plurality of lamp beads are electrically connected with the circuit in the base material; the base material and the lamp beads are sequentially away from the bottom wall. The LED lamp further comprises a dodging membrane located on the side, away from the bottom wall, of the lamp panel, the dodging membrane comprises a base membrane, a prism membrane layer and a diffusion membrane layer, the prism membrane layer and the diffusion membrane layer are located on the two opposite side faces of the base membrane respectively, and the prism membrane layer, the base membrane and the diffusion membrane layer are sequentially away from the lamp panel and stacked. According to the backlight module, the problem of shadow of a lamp panel of the mini LED backlight module is solved, meanwhile, the cost of the mini LED backlight module can be reduced, and the mini LED backlight module is light and thin.
