  • Patent number: 10928581
    Abstract: The present invention discloses to a backlight module and a display device. A flexible printed circuit board is connected to a step of a plastic frame, so that the flexible printed circuit board can be prevented from being adhered to a light guide plate, and thus a distance between a light source and an iron frame can be reduced, and heat dissipation performance of the backlight module can be enhanced. A blocking wall is disposed on each of two side faces of a light-emitting unit perpendicular to the plastic frame, and a reflective film is disposed on a side surface of the blocking wall facing the light-emitting unit, so that light emitted from the light-emitting unit can be collected and reflected, and a greater amount of light can enter the light guide plate from the light-emitting unit, enhancing luminous efficiency of the backlight module, and reducing manufacturing costs.
