Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a lamp panel which comprises a plurality of light-emitting elements arranged in an array; a first rubber frame arranged around the lamp panel; an iron frame comprising a back plate and side plates, wherein the backboard is located on the side, away from the light-emitting face, of the lamp panel, the side plates surround the first rubber frame, and the first rubber frame is fixed to the sides, close to the lamp panel, of the side plates; a color conversion film which is located on the light-emitting surface side of the lamp panel and extends to the first surface of the first rubber frame, wherein the part, in contact with the first surface, of the color conversion film is a first extension part, and the first surface is the surface of one side, deviating from the backboard, of the first rubber frame; a first optical assembly located on the side, away from the lamp panel, of the color conversion film; and a second rubber frame which covers the side plates, the first rubber frame and the first extension part and at least surrounds the first optical assembly. According to the backlight module of the invention, the problem of blue edge display can be solved, and the beneficial effect of improving the display quality can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to a backlight module and a display device. Background technique [0002] A liquid crystal display is a display that relies on a backlight module to emit light and display images on a liquid crystal display panel. Among them, the backlight module uses a light-emitting diode (LED) as a light source, especially the direct type backlight module, which usually uses a blue LED chip as a light source, and then cooperates with a color conversion module to convert the blue light emitted by the blue LED chip. Mixed into white light, so that the liquid crystal display has a high color gamut. [0003] However, with the requirement of the narrow frame of the liquid crystal display, the size of the light-shielding tape set in the liquid crystal display is reduced accordingly, so that the light-shielding tape cannot absorb the blue light leaking from the edge, so that there is a bl...
