世界电子纸显示技术专利计量学研究

World Patent Bibliometrics of Electronic Paper Display Technologies

近年来电子纸显示技术呈爆发式增长趋势,向着彩色、更大尺寸、软性基板、新型显示技术发展,逐渐走向成熟、产业链初步完善。利用德温特专利数据库、汤姆森数据分析软件、Aureka分析平台等分析工具,对世界电子纸显示技术专利进行定量分析。重点分析电子纸专利技术的总体发展趋势、国家/地区专利分布和发展趋势、主要专利权人竞争情况、专利保护策略、技术领域特点、专利地图等,为我国电子纸核心显示技术研发提供有益的参考启示。

In recent years, e-paper display technologies are developed rapidly. The future technology develop- ments are towards to full color, larger size, flexible substrate and new display technologies, and the technologies are becoming matured, the industry chain is initially formed. World patents of e-paper display technologies are analyzed by Derwent patent database, Thomson data analysis software, Aureka analysis platform. The distribution of years, countries, research institutions, protection strategies, technology areas, and patent maps are analyzed to reflect the overall development of e-paper display technologies. So these can provides useful reference for the electronic paper in China.
