Beschreibung
Zusammenfassung:	A LCD display comprises a backlight assembly that includes a backlight substrate, one or more first white LEDs coupled to the backlight substrate and configured to produce a first light output, and one or more second white LEDs coupled to the backlight substrate and configured to produce a second light output. A light integration unit is coupled to the backlight assembly and configured to produce a combined output from the first light output and the second light output, the combined output having a desired luminance and chrominance. A LCD assembly is coupled to the light integration unit.
