Abstract: A display device and a backlight module thereof are provided. The backlight module includes a collimated light source and a light guide plate. The collimated light source configured to generate a collimated light. The light guide plate has a bottom surface and a top surface opposite to each other, and a light entrance surface connected to ends of the bottom and top surfaces respectively for receiving collimated light from the collimated light source. The bottom surface inclines toward the top surface from the end of the bottom surface connected to the light entrance surface. A plurality of first grooves are disposed side by side on the bottom surface and respectively extend along the light entrance surface. The first groove has a first light receiving surface with a first end extending toward the top surface and inclining away from the light entrance surface.

Abstract: The present invention provides a backlight module, comprising a light source module and an optical control layer disposed on the light source module. The optical control layer comprises a first optical film and a second optical film. The first optical film has a first overlap area on a first side, the first overlap area comprises first inner openings; the second optical film comprises a second overlap area near the first overlap area. The second overlap area matches the first overlap area. The second overlap area comprises second outer openings corresponding to the first inner openings.

Abstract: An LED illumination structure without a light guide plate (LGP) includes an optical bottom plate, a plurality of LED illumination components arranged at least along one side edge of the optical bottom plate and a plurality of reflecting structures parallel to the LED illumination components formed on the optical bottom plate from two opposite side edges of the optical bottom plate to a center of the optical bottom plate. The reflecting structures are in a shape of tapered embossment and include a first side facing the center of the optical bottom plate and a second side facing the side edges of the optical bottom plate. An optical film is arranged in a raising direction of the reflecting structures of the optical bottom plate. The present invention is applicable to an illumination lamp for generating a uniform light emitting or may further be an illumination structure for projecting a light source of a bare-eyed 3D image.
