Title: Highly reliable stacked white organic light emitting device

Abstract

An organic light emitting device (OLED) is provided that includes a cathode and an anode; a blue emitting layer; and at least two hybrid red/green emitting layers. One of the at least two hybrid red/green emitting layers is a cathode side, red/green emitting layer that is disposed between the cathode and the blue emitting layer. The second of the at least two hybrid red/green emitting layers is an anode side, red/green emitting layer that is disposed between the blue emitting layer and the anode. The OLED emits white light.

White light-emitting organic electroluminescent devices

Patent Shiang, Joseph John; Duggal, Anil Raj; Parthasarathy, Gautam

A light-emitting device comprises a light-emitting member, which comprises two electrodes, at least two organic electroluminescent ("EL") materials disposed between the electrodes, a charge blocking material disposed between the electrodes, and at least one photoluminescent ("PL") material. The light-emitting member emits electromagnetic ("EM") radiation having a first spectrum in response to a voltage applied across the two electrodes. The PL material absorbs a portion of the EM radiation emitted by the light-emitting member and emits EM radiation having second spectrum different than the first spectrum. Each of the organic EL materials emits EM radiation having a wavelength range selected frommore »« less

.pi.-conjugated heavy-metal polymers for organic white-light-emitting diodes

Patent Vardeny, Zeev Valentine; Wojcik, Leonard; Drori, Tomer

A polymer mixture emits a broad spectrum of visible light that appears white or near-white in the aggregate. The polymer mixture comprises two (or more) components in the active layer. A heavy atom, such as platinum and/or iridium, present in the backbone of the mixture acts via a spin-orbit coupling mechanism to cause the ratio of fluorescent to phosphorescent light emission bands to be of approximately equal strength. These two broad emissions overlap, resulting in an emission spectrum that appears to the eye to be white.
