A backlight module. The backlight module includes a backplane, a backlight light source, a first light conversion layer, and a first light leveling layer. The backplane includes a receiving space, and the backlight light source is fixed on a first inner surface of the receiving space. The first light conversion layer is positioned on the light emitting side of the backlight light source, and there is a first distance between the first light conversion layer and a second inner surface of the receiving space. The first inner surface and the second inner surface intersect to form a right angle. The first light leveling layer is positioned on the side of the first light conversion layer away from an outer surface of the backlight light source. A second light conversion layer is laid on a first target area of the first light leveling layer, and a projection area of the second light conversion layer on the first inner surface covers a projection area of a first area of the first light conversion layer on the first inner surface. A light conversion function of a second area of the first light conversion layer is stronger than the light conversion function of the first area, and the second area includes an area of the first light conversion layer that is different from the first area.

Backlight module and display device

A backlight assembly and its formation method, and a display apparatus are provided in the present disclosure. The formation method includes a circuit board; a plurality of light-emitting elements, disposed at a side of the circuit board; and a light guide element, configured to transmit light emitted from the plurality of light-emitting elements to a display element according to a preset light-guiding path. The backlight assembly transmits the light emitted from the light-emitting elements to the display element according to the preset light-guiding path through the light guide element, which improves the utilization rate of the light emitted from the light-emitting elements and emits higher brightness backlight through relatively low energy consumption.
