Abstract
An OLED display device includes an array of light emitting pixels, each pixel having three or more OLEDs for emitting different colors of light specifying a gamut and at least one additional OLED for emitting a color of light within the gamut, wherein the power efficiency of the additional OLED is higher than the luminance efficiency of at least one of the three or more OLEDs; and means for driving the OLEDs in the pixels to produce a given color and luminance at a reduced power usage.
