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, comprising: a metal frame, a light guide plate, a light source, a plastic frame and a tank body; the first side wall and the second side wall of the metal frame are located side, the third side wall and the fourth side wall are located on opposite sides of the bottom plate along the second direction, and an accommodation cavity is formed between the bottom plate and the side wall; the first side wall includes at least one special-shaped portion, and the special-shaped portion faces the accommodation cavity The inside of the light guide plate is raised to form a groove; the light guide plate, the light source and the plastic frame are all set in the accommodating cavity; the plastic frame is located between the light guide plate and the side wall, the light source and the light guide plate are arranged along the second direction, and the light source is located on the light guide plate Between the third side wall and the third side wall; the plastic frame includes at least one first notch. In the second direction, the first notch is located on the side of the tank body away from the light source, and a first light guide part is arranged in the first notch. Compared with the prior art, the brightness uniformity of the light emitting area of the backlight module can be effectively improved, and the display effect of the display device can be improved.
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...
