    摘要: A light-emitting device comprises a light-emitting member, which comprises two electrodes and an organic electroluminescent material disposed between the electrodes, and at least one organic photoluminescent (“PL”) material. The light-emitting member emits light having a first spectrum in response to a voltage applied across the two electrodes. The organic PL material absorbs a portion of the light emitted by the light-emitting member and emits light having second spectrum different than the first spectrum. The light-emitting device can include an inorganic PL material that absorbs another portion of the light emitted from the light-emitting member and emits light having a third spectrum different than both the first and the second spectra.

    摘要: A device structure and method for outdoor signs utilizing organic light emitting device (OLED) technology. Exemplary embodiments of the device include an OLED that is patterned into a sign combined with an exterior layer consisting of a highly scattering, non-absorbing coating over the OLED emitting regions and a highly absorbing coating over the non-emitting regions. The result is a sign that can be viewed using organic electroluminescent (EL) light under low ambient light level conditions, and due to the exterior coating, can also be viewed under high ambient light conditions.
