Abstract
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.
