Abstract

The invention provides a backlight module and a display device. The backlight module comprises a light guide plate, a back plate and at least one light-emitting element. A plurality of grooves are formed in the face, attached to the back plate, of the light guide plate, fluorescent powder is arranged on the surfaces of the grooves, and the fluorescent powder can generate white light after being excited by the light-emitting elements. The light-emitting elements are arranged on the back plate and are placed in the grooves of the light guide plate. According to the backlight module and the display device, the light guide plate is introduced in the downright light-emitting element arrangement mode, the light-emitting elements are arranged in the grooves of the light guide plate, the backlight module can guarantee the thinness of the display device and is also suitable for the narrow bezel design, and high application value is achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module and a display device comprising the same. Background technique [0002] Liquid crystal displays usually have two backlight distribution methods, including direct-type and side-type. In the direct-type backlight module, the light-emitting elements are arranged on the back panel of the liquid crystal display, while the side-type light-emitting elements are distributed around the liquid crystal display. The light guide plate forms a uniform surface light source through reflection. In the traditional module design, the direct-type module design needs to leave a certain light mixing distance, which is not conducive to the thinning of the display device; and the side-type light-incoming method needs to occupy a certain amount of space on the side because the light-emitting element The space is not conducive to the design of the narrow frame of the display devic...
