Abstract:
An light-emitting diode device, including a substrate; and a reflective electrode and a semi-transparent electrode formed over the substrate and an unpatterned white light-emitting layer formed between the reflective electrode and the semi-transparent electrode, the reflective electrode, semi-transparent electrode, and unpatterned white-light-emitting layer forming an optical microcavity, and wherein either the reflective or semi-transparent electrodes is patterned to form a plurality of independently controllable light-emitting elements with at least one light-emitting element having no color filter. Color filters are formed over a side of the semi-transparent electrodes opposite the unpatterned white light-emitting layer in correspondence with the light-emitting elements, the color filters having at least two different colors.
