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.

Electroluminescent display screen having a transparent substrate (1), a surface (2) of which is provided with a first, transparent electrode layer (3) on which a metal top layer (12) is formed. The metal top layer is provided with a layer of insulating material (4). Windows (5) in accordance with a pattern (8, 9, 10) to be displayed are formed in the layer of insulating material as well as in the metal top layer. An organic electroluminescent layer (6) is deposited on said layer of insulating material and in said windows. This layer is provided with a second electrode layer (7). Said pattern (8, 9, 10) can be displayed without differences in brightness.

A description is given of a method of providing an electroluminescent device (20) comprising an active layer (5) of conjugated 2,5-alkyl- or alkoxy-substituted poly(p-phenylene vinylene) with inactive regions (51) and emissive regions (52) by means of patterned irradiation with UV light. Both regions (51 and 52) of the active layer (5) show a clear difference in electroluminescence, electrical resistance and solubility. By means of the above-described effects, displays can be manufactured without making use of structured electrode layers (3 and 11).

The invention relates to a method for producing structured organic light-emitting diodes, wherein a hole injection layer, an emitter layer and a cathode are deposited on a carrier coated with indium tin oxide. The hole injection layer and/or the emitter layer are deposited in a structured manner. The invention can be used in the field of novel security components that are self-luminous with electric excitation. The invention is used for displaying structures within an areally luminous organic light-emitting diode and is used for verifying and checking products. The invention further relates to an organic light-emitting diode produced in said manner.
