Abstract
An OLED display for producing a full color image, comprising a plurality of at least four different colored pixels including three different colored addressable gamut-defining pixels and a fourth addressable within-gamut pixel, each pixel having an organic light-emitting diode with first and second electrodes and one or more organic light-emitting layers provided between the electrodes; the OLED display having a selected display white point, display peak luminance, gamut-defining pixel peak luminances and within-gamut pixel peak luminance; and drive circuitry for regulating luminance of the organic light-emitting diode of each of the colored pixels wherein the sum of the gamut-defining pixel peak luminances is less than the display peak luminance.
