摘要： A light source comprises an organic light-emitting device, which emits radiation having a first spectrum, and a phosphor layer, which absorbs a portion of the light emitted by the organic light-emitting layer and which emits light having a second spectrum. The organic light-emitting device comprises an organic light-emitting layer disposed between a pair of electrodes, and at least a charge-blocking layer disposed between the organic light-emitting layer and one of the electrodes. The phosphor layer typically absorbs less than all of the light emitted by the organic light-emitting layer and typically covers the entire organic light-emitting device. The light emitted by the organic light-emitting layer is mixed with the light emitted by the phosphor layer to produce light having a third spectrum.

摘要： A light source comprises an organic light emitting device which emits radiation having a first spectrum and a phosphor layer which absorbs a portion of the light emitted by the organic light emitting layer and which emits light having a second spectrum. The phosphor layer typically absorbs less than all of the light emitted by the organic light emitting layer and typically covers the entire organic light emitting device. The light emitted by the organic light emitting layer is mixed with the light emitted by the phosphor layer to produce light having a third spectrum. Exemplary embodiments of the invention provide advantages over known devices. For example, because a phosphor layer is provided, the light emitted from the organic light emitting device is scattered, which provides improved uniformity in light output over the area of the light source. Also, because most phosphors are relatively stable over time, the light source has good color stability over time.

摘要： The invention relates to a luminescent display comprising a first electrode, a second electrode, an organic light emitting layer disposed between the first and second electrodes, and a luminescent material which receives light from the organic light emitting layer and converts the light to a different wavelength, wherein the first and second electrodes together define an overlap region in which the organic light emitting layer is activated to emit light, and the luminescent material is disposed in a portion of the overlap region. The invention also relates to a method comprising the steps of creating an image and printing the image on a light emitting device comprising an organic light emitting layer after the light emitting device has been formed. The image may be created, for example on a personal computer, and printed with an inkjet printer. The image may be printed in phosphors which emit light of one wavelength upon absorbing light of a different wavelength from the organic light emitting layer. Various embodiments of the invention allow customized luminescent displays to be easily fabricated by end users by applying a phosphor pattern to a preformed, encapsulated light emitting device.
