Title: OPTICAL FILM ASSEMBLY, BACKLIGHT MODULE AND DISPLAY DEVICE
Abstract:
An optical film assembly, a backlight module, and a display device. The backlight module comprises a light source (101) emitting at least a first type of light; and adhered a first optical film (102) and a second optical film (103). The first optical film (102) comprises a functional layer but does not comprise a base layer, the functional layer being a diffusion film, a brightness enhancement film, a reflective film or a prism film layer; the second optical film (103) is a light conversion film, and the light conversion film receives the first type of light and converts the first type of light into at least a second type of light for emergence, so that the light-emitting angle of the backlight module matches a wide viewing angle display requirement. Thus, a display device having the backlight module achieves a wide viewing angle effect.
