ABSTRACT:
An improved electrical circuit design and method to drive a plurality of LEDs in an LCD backlight in order to produce a uniform color distribution across the entire viewable surface of the display. The embodiments disclosed have features that permit a predetermined reduction in the amount of current provided to the LEDs positioned along the edge of the display region. This results in color uniformity, and consequently, an improved picture quality.
