Abstract:
1. A backlight assembly comprising: a light guide plate (LGP) comprising a side surface and an upper surface connected to the side surface; a light source module comprising a power-transmitting member and a plurality of point light sources being mounted on the power-transmitting member, a portion of the power-transmitting member being disposed on an edge portion of the upper surface adjacent to the side surface, and a light-exiting surface of the point light sources facing the side surface to be adjacent to the side surface; an optical sheet being disposed on the upper surface, an end portion of the optical sheet being disposed between the edge portion of the upper surface and the power-transmitting member to be adjacent to the light-exiting surface, and reflective members disposed on the power-transmitting member; wherein the point light sources each have a first surface that is a light emitting surface, a second surface opposite to the first surface, and side surfaces extending between the first and second surfaces; wherein areas between adjacent ones of the point light sources are defined by imaginary lines extending between first surfaces of the adjacent ones of the point light sources, by imaginary lines extending between second surfaces of the adjacent ones of the point light sources, and by side surfaces of the adjacent ones of the point light sources; and wherein the reflective members are disposed in the areas between adjacent ones of the point light sources, and the end portion of the optical sheet has an embossing pattern defined by a plurality of recesses and a plurality of protrusions, the reflective members are extended to be disposed within the recesses, the protrusions correspond with the point light sources, and the protrusions make contact with the power-transmitting member and the upper surface of the LGP.
