Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a back plate, a flexible circuit board and a light-emitting component, wherein the back plate comprisesa bottom and a side wall connected with the edge of the bottom; an opening is formed in the side wall; the bottom and the side wall form an accommodating cavity; the flexible circuit board comprises afirst part, a second part and a third part; the third part is positioned in the accommodating cavity, and the first part and the second part stretch into the accommodating cavity from the opening andare connected with the third part; the light-emitting component is positioned on the side surface, away from the bottom, of the third part; the first part is bent to the side, away from the accommodating cavity, of the bottom; the second part comprises a first sub-part and a second sub-part which are connected with each other, the first sub-part extends along the direction, away from the bottom,of the side wall and is positioned on the side, away from the containing cavity, of the side wall, the second sub-part extends along a plane parallel to the plane of the third part and is positioned on the side, away from the bottom, of the side wall, and the opening is covered with the first sub-part, so that light emitted by the light-emitting component is prevented from being emitted from the opening, and the light leakage problem of the backlight module is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a backlight module and a display device. Background technique [0002] The liquid crystal display panel is a commonly used flat panel display at present, and the backlight module is an important part of the liquid crystal display panel, which is used to provide a light source for the liquid crystal display panel when the liquid crystal display panel is working. With the rapid development of display technology, the market has higher and higher requirements for the performance and taste of backlight modules, such as high brightness, narrow frame, and picture quality. However, it is accompanied by a decline in the quality of the backlight, especially the problem of light leakage from the backlight module. [0003] In the prior art, the backlight module includes a backplane, a flexible circuit board and a light-emitting element, wherein the backplane inclu...
