ABSTRACT:
A multicolor organic light emitting display device employs angle-walled blue, green and red emitting mesas, with optional metal reflectors on the angled walls, in a plurality of pixels. The angle-walled mesas, which resemble truncated pyramids, direct light out of the mesa by reflection from the mesa side walls or by mirror reflection. The device of the present invention reduces waveguiding, thus simultaneously increasing both display brightness and resolution.
