Abstract

A method of purifying a primary color including providing an organic light emitting diode having a diode light output with a broad spectrum that includes a fraction of the primary color. A microcavity structure is formed in cooperation with the organic light emitting diode to define an optical length of the microcavity structure, and the optical length of the microcavity structure being such that light emitted from the microcavity structure is the primary color, purified.
