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.
