Abstract

The invention relates to the technical field of displays and discloses a backlight module and a display device, aiming at reducing situations that a diffuser is warped up, edges of a light outlet surface of a backlight source are brightened and the brightness and darkness are not even, and improving the display effect of the display device. The backlight module comprises a light guide plate, a light source on an incident side of the light guide plate, the diffuser on an emergent side of the light guide plate, a lens layer on one side, opposite to the light plate, of the diffuser, and a shading tape on the periphery of the light outlet surface of the backlight module, and further comprises a flexible light absorbing material layer on one side, towards the light guide plate, of the shading tape, wherein the flexible light absorbing material layer is attached to the part, close to the emergent side of the light guide plate, of the shading tape, and the side, opposite to the shading tape, of the flexible light absorbing material layer resists against the side, opposite to the light guide plate, of the diffuser.

Description

technical field [0001] The invention relates to the technical field of display preparation, in particular to a backlight module and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. Since the liquid crystal panel itself does not emit light, the light source provided by the backlight module is needed to display images normally. Therefore, the backlight module becomes one of the key components of the liquid crystal display device. Backlight modules are divided into side-t...
