The backlight module includes a light source emitting at least a first light, a first optical film, and a second optical film laminated to the first optical film, wherein the first optical film includes a base film and a functional layer stacking up to the base film, the functional layer is a diffusion film, a brightness enhancement film, a reflection film, or a prism film, the second optical film is a light conversion layer, the light conversion layer receives the first light and converts the first light to a second light to emit, such that a light emission angle of the backlight module matches a requirement of wide viewing angle. The invention could broaden the light emitting angle of the backlight module to make the display device with the backlight module achieve wide viewing angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical film assembly, backlight module and display device","description":"The invention provides an optical film assembly, a backlight module, and a display device.
