摘要： A backlight assembly includes a plurality of light sources emitting light and a diffusion plate. The diffusion plate includes an incident surface on which the light is incident, an exit surface which is opposite the incident surface and from which the light exits, and first and second lens patterns which are disposed on the exit surface and have different shapes from each other. Each of the first lens patterns includes a first curved portion which forms a curve and first linear portions which extend from both ends of the first curved portion, respectively. Each of the second lens patterns includes a second curved portion which forms a curve and second linear portions which extend from both ends of the second curved portion, respectively.

摘要： A backlight assembly includes a light source generating light and a first optical member diffusing the light. The first optical member includes a first diffusion member provided on an exit surface of the first optical member, from which the light exits, to diffuse the light. The first diffusion member includes a plurality of edges each having a curved shape and extending between the exit surface and a vertex of the first diffusion member. Accordingly, the light exiting through the exit surface is effectively diffused by the edges of the first diffusion member.

摘要： A backlight assembly that is adapted for use with an image displaying flat panel includes a light guide plate assembly and one or more light sources disposed under the light guide plate assembly. An upper portion of the light guide plate assembly is overlapped by a display area of the flat panel while a lower portion is disposed under the upper portion, and includes light guiding material for redirecting sourced light as well as reflectors for also redirecting light sourced from small, light sourcing areas underneath the upper portion for redistribution into the larger area of light guiding material provided in the upper portion of the light guide plate assembly. The upper portion also has one or more light reflectors. In one embodiment, opposed ones of light sources are angled so they don't shine light directly into one another.
