At least one of the electrodes is transparent. At least one of the electrodes is patterned to define independently controllable light-emitting areas. A cover is formed over the LED. The cover or substrate is transparent. A light-scattering layer is formed between the cover and substrate for scattering light.

    摘要： A method for forming a color organic light-emitting device including depositing a first electrode over a substrate; depositing a first emissive layer over the first electrode for producing a first colored light in response to hole-electron recombination; and selectively patternwise depositing a hole-blocking layer over the first emissive layer. The method also includes depositing a second emissive layer over the hole-blocking layer which in response to hole-electron recombination emits colored light different from the colored light emitted from the first emissive layer; depositing a second electrode over the second emissive layer; and whereby the patternwise deposition of the hole-blocking layer has been selected to substantially shift hole-electron recombination from the second to the first emissive layers.

    摘要： A method for fabrication of a rear projection article forms an arrangement of refractive elements on one surface of a transparent support and forms an apertured surface on the opposite surface of the support. A photographic positive reversal emulsion is applied to the opposite surface of the substrate to form a light-sensitive layer. Visible light is directed, as exposure radiation, through the refractive elements, exposing the light sensitive layer to form an exposed layer. The exposed layer is developed photographically using a positive reversal process to form the apertured surface thereby.
