Abstract: The present invention provides a backlight module. The backlight module includes a light source, an optical film, a diffusion plate, a back plate, and LED strips disposed on the back plate. The back plate forms a receiving cavity and includes at least two coupled LED strips. The light source, the diffusion plate, and the optical film are arranged in the receiving cavity. Wherein, LED lamps which are at an end of the LED strips and adjacent to a coupling position have an illuminating inner diameter on the diffusion plate, and the illuminating inner diameter is greater than an edge length to the coupling position, which improves technical problems of poor backlight mixing in backlight modules.

Abstract: The present invention provides a backlight module and a display device. The present invention splices a substrate on a reflection plate. The reflection layer can effectively replace the reflection plate in function because of a high reflectivity of the reflection layer on the spliced portion between the substrate and the reflection plate, which guarantees extension of light and lowers requirement for assembling precision.

Abstract: A color filter substrate arranged in an LCD panel is provided. The color filter substrate includes a transparent substrate, a plurality of QDs arranged on the transparent substrate, a band-pass filter film arranged on the transparent substrate, and a polarizing layer, arranged on the band-pass filter film. The QDs includes a blue QD, a green QD, and a red QD. Owing to the characteristics of band-pass filter films, the blue light can pass by and the green light and the red light can be reflected. So the exciting light can be propagated in an effective direction according to design requirements so as to avoid the technical problem of mutual crosstalk, thereby improving the light efficiency of the structure of the color filter substrate and improving the display quality of the LCD panel.
