Abstract
A light bar includes a plurality of first color light emitting LEDs including a first subset of first color light emitting LEDs and a second subset of first color light emitting LEDs, a plurality of second color light emitting LEDs, where the second color is different from the first color, and a plurality of third color light emitting LEDs, where the third color is different from the first and the second colors. The second subset of first color light emitting LEDs are electrically connected in series with a larger electrical load than the first subset of first color light emitting LEDs. This light bar electrical configuration allows compensation and correction for locations on the light guide plate used in back light units where imperfect mixing of the 3 primary colors provided by the individual LED emitters on the light bar occurs.
