In order to narrow the frame of the liquid crystal display, the current practice is to design the liquid crystal display as a special-shaped display other than a regular rectangle. Although this type of special-shaped display can better avoid functional devices such as cameras and speakers, and has a higher screen occupation However, the light emitted by the light-emitting device in the backlight module often forms a bright area due to excessive concentration in the special-shaped area, or forms a dark area because it cannot be emitted, resulting in uneven brightness of the entire screen when the LCD displays the screen. Difficult to meet people's visual effect needs

The invention discloses a backlight module and a display device, the backlight module comprises a metal frame, a light guide plate, a light source, a rubber frame and a groove body; the first side wall and second side wall of the metal frame are positioned at two opposite sides of a bottom plate in the first direction, the third side wall and fourth side wall are positioned at two opposite sides of the bottom plate in the second direction, and an containing cavity is formed between the bottom plate and the side walls; the first side wall comprises at least one special-shaped part, and the special-shaped part protrudes towards the inner part of the containing cavity to form a groove body; the light guide plate, the light source and the rubber frame are all arranged in the containing cavity;the glue frame is positioned between the light guide plate and the side walls, the light source and the light guide plate are arranged in the second direction, and the light source is positioned between the light guide plate and the third side wall; the rubber frame comprises at least one first notch, the first notch is positioned at one side of the groove body, away from the light source, in thesecond direction, and the first notch is internally provided with the first light guide part. Compared with the prior art, the device can effectively improve the uniformity of the brightness of the light emitting area of the backlight module and improve the display effect of the display device.
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] Since the liquid crystal itself does not emit light, in various liquid crystal displays (Liquid Crystal Display, LCD), it is necessary to rely on an external backlight module (Back Light) to provide a light source, so that the LCD display screen, so that the luminous effect of the backlight module will be Directly affect the visual effect of the liquid crystal display. [0003] In recent years, with the continuous improvement of people's requirements for visual effects, liquid crystal displays with narrow borders are gradually favored by people. Due to the narrower bezels and higher screen-to-body ratios of LCDs, people are less constrained visually when viewing the experience. In order to narrow the frame of the liquid crystal display, the current practice is to design the liquid crystal d...
