Abstract
An OLED device includes a pixel having a plurality of individually addressable light emitting elements including a light emitting element for emitting white light, and one or more light emitting elements for emitting colored light; at least one of the light emitting elements being stacked on top of another of the light emitting elements; and the white light emitting element(s) being more efficient than at least one of the colored light emitting element(s).
