Abstract

The invention discloses a backlight module and a display device, comprising: at least one notch located at the edge; a light exit area, a non-light exit area surrounding the light exit area; the light exit area includes a first edge, and the first edge is recessed toward the inside of the light exit area to form at least A first notch; the non-light-emitting area includes a first non-light-emitting area adapted to the position and shape of the first notch; a light guide plate and a light source assembly located in the light-exit area, the light source assembly is located on at least one side of the light guide plate, and the light source assembly The light-emitting surface faces the light-incident surface of the light guide plate; the plastic frame located in the non-light-emitting area, the plastic frame includes a first sub-plastic frame located in the first non-light-emitting area, and the first sub-plastic frame includes an inner surface close to the side of the light guide plate; concave The groove includes a connected first surface, a second surface and a third surface, and the first surface and the third surface are oppositely arranged at two ends of the second surface along a direction perpendicular to the light guide plate. Improve the display effect of the display terminal.

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] The backlight module is one of the key components of the liquid crystal display, which is used to provide sufficient brightness and evenly distributed light sources for the liquid crystal display panel, and its luminous effect will directly affect the visual effect of the liquid crystal display. With the continuous development of liquid crystal display technology, the application fields of liquid crystal displays, especially color liquid crystal displays, are also constantly expanding. Driven by the liquid crystal display market, the backlight industry presents a scene of prosperity. The performance of the backlight will not only directly affect the image quality of the LCD, the cost of the backlight accounts for 30-50% of the LCD module, and the power consumption accounts for 75% of the mod...
