Abstract

The invention discloses a backlight module, a manufacturing method and a display device. The backlight module comprises a back plate, a light guide plate and an optical film, wherein the back plate isprovided with a bottom and side frames surrounding the bottom, the light guide plate and the optical film are arranged at the bottom of the back plate, and the optical film is located on the light emitting side of the light guide plate; frame glue, arranged at the bottom of the back plate and located between the side frame and the light guide plate, the frame glue, the optical film and the back plate forming a closed space, and blue light absorbing materials being arranged in the frame glue. Therefore, the backlight module has a good function of preventing blue light leakage, the phenomenon of blue bright lines of a display device applying the backlight module can be effectively improved, and the display device can obtain a good display effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a manufacturing method, and a display device. Background technique [0002] The backlight module is one of the key components of the liquid crystal display device, which is used to provide sufficient and uniform light for the liquid crystal display panel so that it can display images normally. The backlight module is mainly composed of light source, light guide plate, optical film, plastic frame, etc. It has the characteristics of high brightness, long life, and uniform light emission. [0003] However, the current backlight module, manufacturing method, and display device still need to be improved. Contents of the invention [0004] The present invention is based on the inventor's discovery and recognition of the following facts and problems: [0005] At present, backlight modules usually use blue LEDs as light sources. The inventors found that there is ...
