Abstract

The invention provides a backlight module and a display device. The backlight module comprises a back plate, a bottom reflector plate, a side reflector plate and a plurality of light sources, wherein the back plate comprises a bottom plate and side plates arranged on at least one side of the bottom plate, the bottom reflector plate is arranged on one side of the bottom plate, and the light sources are arranged on the side, away from the bottom plate, of the bottom reflector plate; the side reflector plate is arranged on the side, close to the bottom plate, of the side plate. The side reflector plates are arranged on the side plates, and when light emitted by the light sources irradiates the side plates, the light is reflected to the quantum dot film through the side reflector plates, so that more blue light can be output after penetrating through the quantum dot film, the blue light leaked along the edge of the backlight module is reduced, on the other hand, the brightness of the periphery of the bottom reflector plate is also improved through reflection of the side reflector plates, so that the problem that the periphery of a picture of the liquid crystal display panel is blued and darkened is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a backlight module and a display device. Background technique [0002] With the development of display technology, miniature (Mini) light emitting diodes (Light Emitting Diode, LED) have been more and more widely used. Due to the small pixel distance, Mini-LED combines the advantages of high resolution, low power consumption, high brightness, and high color saturation. Compared with display devices using traditional LED backlights, display devices using MiniLED backlight technology perform better in terms of dynamic contrast, brightness, color gamut, and viewing angle, and have advantages such as thinness, high image quality, low power consumption, and energy saving. . [0003] In existing display devices, blue LED chips are usually used together with quantum dot films, and high-energy blue light is used to excite the quantum dot ...
