由于具有色域覆盖率大、色饱和度高和低功耗等特点，激光显示技术被认为是最具有发展前景的显示技术之一。通过检索欧洲专利局世界范围专利数据库、美国专利商标局专利数据库和中国国家知识产权局专利数据库，对2001～2010年公开的5 898件激光显示相关专利进行了数据挖掘，研究了激光显示技术的发展概况，将其按照技术和竞争两个方面进行了统计分析，全面揭示了世界激光显示领域技术的分布格局与发展态势。

Laser projection display has advantages over traditional projection technologies, such as extended color gamut, greater colors saturation and low power consumption. It is regarded as a promising generation of full-color projection display technology. This paper investigated related patent documents from the State Intellectual Property Office of the People's Republic of China, United States Patent and Trademark Office and European Patent Office during the year of 2001～2010. The technology overview and future trend of laser display were discussed based on the analysis of 5 898 laser display patents.
