The invention discloses a backlight module and a display device. The backlight module includes a housing, a backlight source and a light guide plate. The housing includes a bottom plate and a side plate. The side plate and the bottom plate form an accommodation cavity for accommodating the backlight source and the light guide plate. The backlight source and the light guide plate are arranged opposite to each other along the first direction, the light exit surface of the backlight source intersects the light exit surface of the light guide plate, the backlight source includes a plurality of LED lamps arranged along the second direction, and each LED lamp includes a lamp socket located in the middle The lamp port has a light exit side, the light exit side is opposite to the light guide plate, and the first direction intersects with the second direction; the side of the light guide plate close to the backlight includes a plurality of first regions, and the first regions correspond to the lamp port part one by one , and the orthographic projection of the first area on the plane where the base plate is located abuts against the orthographic projection of the socket part on the plane where the base plate is located, and in the first area, the side close to the base plate includes at least one lamp arranged along the first direction and extending in the second direction first groove. The invention solves the problem of yellowing of the front of the side-entry backlight source.
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] At present, the backlight module used in the display panel is usually equipped with a side-type backlight on the side of the light guide plate. The light emitting surface of the light guide plate emits evenly, realizing the conversion from a point light source to a surface light source. [0003] As the frame of the display device becomes narrower, the problem of yellowish vision in front of the side-entry backlight becomes more and more serious. Therefore, it is urgent to provide a narrow-frame backlight module that can solve the problem of yellowish vision in front of the side-entry backlight. Group. Contents of the invention [0004] In view of this, the present invention provides a backlight module, which is used to solve the problem of yellowish vision in front of the side-type backli...
