Problems solved by technology

[0004] However, for figure 2 In the structure of the backlight module shown, since the opening 23 is provided on the side 21, when the light-emitting element 10 emits light, light leakage will occur at the opening 23, which will cause the liquid crystal display to also have light leakage at this position, resulting in a decline in product quality. Customer Experience Declines

Abstract

The invention discloses a backlight module and a display device, and relates to the technical field of display. In the embodiment of the invention, a light shielding part is arranged in the middle region of a flexible circuit board, and the light shielding part and a light emitting element are located on the same side of the flexible circuit board, so that an opening is arranged at the side; whenthe flexible circuit board is arranged close to the bottom surface of a frame body, the light shielding part can prevent light rays emitted by the light emitting element from leaking out of the opening, so that the problem of light leakage of the backlight module caused when the flexible circuit board is arranged close to the bottom surface of the frame body is solved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] A liquid crystal display generally includes a backlight module, and the display function can be realized by using the backlight provided by the backlight module. The backlight module may include: a flexible circuit board 30, a light-emitting element 10 fixed on the flexible circuit board 30, a light guide plate 40 located on the light-emitting side of the light-emitting element 10, and a frame body 20, wherein the frame body 20 includes a bottom surface 22 and side 21, the flexible circuit board 30 is set away from the bottom surface 22 (such as figure 1 The "positive group" structure of the shown backlight module), however, due to the industry's demand for narrow frames, there has been a structure in which the flexible circuit board 30 is arranged close to the bottom surface 22 (such as figure 2 The "reve...
