摘要： A backlight system includes a light guide plate and a light source. The light guide plate includes a light incident surface, a reflective surface adjoining the light incident surface, and a light-emitting surface opposite to the reflective surface. The light guide plate further includes an upper layer and a lower layer under the upper layer. The upper layer includes a substrate portion, a light-emitting surface, a second surface, and a number of projections. The projections extend from the second surface. Each projection has a top extremity adjoining the substrate portion and a bottom face distal from the substrate portion. The lower layer includes a light incident surface, a top surface adjoining the light incident surface, and a reflective surface opposite to the top surface. The top surface of the lower layer abuts the bottom face of the projections.

摘要： A light guide plate includes an incident surface, a reflecting surface, and a plurality of V-shaped projections arrayed on the reflecting surface. The V-shaped projections extend outwardly from the reflecting surface. Each of the V-shaped projection has a triangular cross-section. A vertex angle of the cross-section is in the range from 40° to 95°. A first base angle of the cross-section is in the range from 70° to 90°. A second base angle of the cross-section is in the range from 15° to 50°. A distribution density of the V-shaped projections progressively increases along a direction away from the incident surface. A size of the V-shaped projections progressively increases along a direction away from the incident surface. The light guide plate can be one of a flat sheet having a uniform thickness and a wedge-shape piece.
