Patent ID: 7671832

Claim:
A light emitting device comprising: an arrangement of light emitting diodes (LEDs) for a backlight, the backlight having at least a first backlight edge and an opposite second backlight edge, the LEDs being grouped in an array of clusters, each cluster being formed of a plurality of colors of LEDs whose combined light has a white point, each cluster having the same number of LEDs, the arrangement comprising: a first cluster configured to be adjacent the first backlight edge, the first cluster having a first white point; a plurality of second clusters configured to be not adjacent to either one of the first backlight edge or the second backlight edge, the plurality of second clusters having an average white point different from the first white point; and at least one LED of a first color in the first cluster having a light output characteristic that is different from a light output characteristic of LEDs of the first color in the plurality of second clusters so that the first white point of the first cluster is color shifted with respect to the average white point of the second clusters to at least partially offset an effect of the first cluster being along an edge of the backlight, wherein the plurality of colors comprises a first color, a second color, and a third color, the first cluster having a first LED of the first color that is nearer to the first backlight edge than a second LED of the second color, wherein the first LED in the first cluster has a flux less than an average flux of LEDs of the first color in the plurality of second clusters, and wherein the second LED in the first cluster has a flux greater than an average flux of LEDs of the second color in the plurality of second clusters so that the first white point of the first cluster at least partially offsets an effect of the first cluster being along an edge of the backlight.
