    Abstract: The present invention provides electronic displays and lamps that include a plurality of organic electroluminescent devices that emit polarized light. Displays can be made that include devices that emit the same or nearly the same polarization of light of different colors. For example, a full color pixilated display can be made that emits polarized light. Polarizing filters can be combined with such a display to reduce glare or increase display contrast without significantly reducing the intensity of the emitted light. Displays can also be made that include devices that emit different polarizations of light of the same or different colors. Tunable color of single color polarized light emitting lamps and backlights can also be made.
