Problems solved by technology

Due to the existence of the hollow part 01, part of the light L of the light source 02 is blocked by the hollow part 01 and cannot be transmitted to the area 011 on the side of the hollow part 01 facing away from the light source 02, resulting in a dark area 011, and the backlight module cannot provide a uniform Backlight, reducing display quality

Abstract

The invention discloses a backlight module and a display device, belonging to the technical field of display, comprising: a light source and a multi-layer stacked optical film, the light source is a side-entry light source; a hollowed out part along the thickness direction of the backlight module Through the multi-layer optical film; the hollow part includes a light guide part, the light guide part includes a light-transmitting main part, a first reflective layer and a second reflective layer, the cross section of the main part is ring-shaped; the light guide part is close to the light source The side is the first side, and the side of the light guide part away from the light source is the second side; the inner wall of the main body part on the second side is provided with a first reflective layer; the outer wall of the main part on the second side is provided with a second reflective layer , the second reflective layer includes a plurality of light-transmitting regions; after the light from the light source enters the light-guiding portion, it is reflected between the first reflective layer and the second reflective layer, and at least part of the reflected light is emitted from the light-transmitting regions. Compared with the prior art, the backlight module can provide uniform backlight, thereby improving the 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 in order 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 schematic structural diagram of a backlight module provided in the prior art. figure 1 The illustrated backlight module includes a light source 02 and an optical film (not shown in the figure). After the light L emitted by the light sour...
