Patent attributes
Techniques for providing backlight techniques in liquid crystal flat panel displays are disclosed. According to one aspect of the techniques, the source to backlight a liquid crystal panel includes a plurality of light emitting diodes that are in at least three colors. The exact colors of the light emitting diodes are chosen to cover or exceed a full spectrum of color reproductions in accordance with a television standard (e.g., NTSC or PAL) in addition to a balanced white. In one embodiment, a set of control signals is configured to ensure that the light emitting diodes provide desired and consistent backlighting to a LCD panel. One of the control signals adaptive to a scene or content of a scene causes the backlighting to change accordingly or drastically to create artistic effects required or desired in the scene.
