基于专利分析开展的光学TAC膜竞争态势研究
|
摘要
在专利文献数据的基础上,对光学TAC膜技术、区域和竞争对手等进行深入研究,希望从专利技术成果方面对光学TAC膜的发展现状、竞争态势进行客观评价。研究结果显示,光学TAC膜领域在1970年—2017年共申请专利2272件,研究重点主要集中于配方及工艺技术方面。日本是光学TAC膜的主要技术发源地,而美国、韩国、中国和中国台湾是重要的目标市场。通过深入分析光学TAC膜专利信息,了解该领域的研究现状和竞争态势,可以为我国光学TAC膜技术创新提供一定的借鉴和参考。
Based on the patent literature data,the optical TAC film technology, regions and competitors were studied deeply.We hope to evaluate objectively the development status and competition situation of optical TAC film from the perspective of patented technical achievements. The research results show that a total of 2,272 patents have been applied in the field of optical TAC film from 1970 to 2017. These patents focus mainly on the formulation and technology. The main source of optical TAC film technology is in Japan,while the United States, South Korea, China and China's Taiwan are important target markets. Through in-depth analyzing deeply patent information of optical TAC film, we can understand research status and competition situation of this field. By referencing and consulting these information,we can innovate optical TAC film technology in China.
