Balanced LED backlighting for liquid crystal display (LCD)
Abstract:
Techniques for providing LED-based backlighting in liquid crystal flat panel displays are disclosed. In one embodiment, optical sensors are provided to sense illuminations from colored LED groups and provide feedback signals to a controller so that a desired ratio of the illuminations is maintained. As a result, true colors could be reproduced regardless of possible irregularities that may be happening to LEDs used in the colored LED groups to backlight an LCD panel.
