摘要
对Derwent Innovation Index（DII）专利数据库收录的1995—2011年世界范围内申请的印刷有机发光二极管技术（OLED）专利进行了数据计量分析，给出了印刷OLED专利的年度分布、地区分布、技术重点分布、机构分布，揭示了已展现出明显优势的印刷OLED技术的创新现状和发展趋势，所得结果可为这种新技术的研发决策提供支持与依据。
The paper metrologically analyzes the data of the printed organic light-emitting diode （OLED） patents （1995 -2011 ） collected worldwide by the Derwent Innovation Index database, and investigates the variation of the annual patent amount in the period, the patent amount of each major country, the key techniques of the patents, and the patent amount of each major enterprise, and finally, elaborates the innovation status and development trends of the printed OLED technology, the performance superiority of which is obviously emerging. The results of the study can provide the support and basis for decision on the new technology research.
