Patent ID: 8558782

Claim:
A display, comprising: a backlight configured to operate over a temperature range; a first string of first light emitting diodes arranged within the backlight, wherein the first light emitting diodes have a first chromaticity at an equilibrium temperature of the backlight; a second string of second light emitting diodes arranged within the backlight, wherein the second light emitting diodes have a second chromaticity at the equilibrium temperature of the backlight and wherein the second chromaticity is separated from the first chromaticity by a chromaticity difference greater than a maximum chromaticity shift of the first light emitting diodes over the temperature range; one or more drivers configured to independently drive the first string and the second string at respective driving strengths to produce an emitted white point that corresponds to a target white point; and a controller configured to detect temperature changes within the display and to adjust a ratio of the respective driving strengths to maintain correspondence to the target white point over the temperature range.
