Abstract

The invention discloses a backlight module and a display device and belongs to the technical field of display, including light sources and multilayer optical diaphragms arranged in piles, wherein thelight sources are side entry light sources; a hollow portion, wherein the hollow portion penetrates the multilayer optical diaphragms along the thickness direction of the backlight module; the hollowportion includes a light guide portion, wherein the light guide portion includes a transparent main body portion, a first reflector and a second reflector, and the cross section of the main body portion is annular; a side of the light guide portion close to the light sources is a first side, and a side of the light guide portion away from the light sources is a second side; the inner side wall ofthe main body portion of the second side is provided with the first reflector; the outer side wall of the main body portion of the second side is provided with the second reflector, wherein the secondreflector includes a plurality of transparent areas; after light of the light sources entering the light guide portion, reflection occurs between the first reflector and the second reflector and at least part of reflected light is emitted from the transparent areas. Compared with the prior art, the backlight module and the display device can provide the backlight module with uniform backlight, thereby enhancing display quality.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a backlight module and a display device. Background technique [0002] With the development of display technology, display devices pursue higher and higher screen-to-body ratios, so as to improve the display effect of the display device and improve user experience. [0003] A display device provided in the prior art includes a display module, the display module includes a display panel and a backlight module, and the backlight module provides backlight for the display panel. In the prior art, electronic components such as cameras are integrated inside the display module. [0004] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a backlight module provided by the prior art. figure 1 The shown backlight module includes a light source 02 and an optical film (not shown in the figure). After the light L emitted by the light source 02 pa...
