Zusammenfassung: | The present invention provides a backlight module and display device thereof, including light-guiding plate, frame and a plurality of light sources disposed near incident surface of the light-guiding plate. The backlight module further includes an opaque layer, with one part attached to the frame and the other part disposed on light-emitting surface of light-guiding plate. The opaque layer shields and absorbs partial light emitted directly from the plurality of light sources and light from light-emitting surface covered by opaque layer. With such structure, the rim of the frame can be smaller, even when A/P ratio is less than 0.5, the hotspot phenomenon can be avoided. As such, the present invention improves the optical characteristics of the backlight module and the display quality of the display device, as well as simplifies the assembly and reduces assembly cost. |
