Research Progress for Resource Recovery Technologies of the Waste Liquid Crystal Display

液晶显示器是电脑、电视和手机的重要组成部件,对废弃液晶显示器资源化回收技术的研究对于保护环境和回收其中的有价资源均具有重要的意义。综述了近年来液晶显示器中各组分进行资源化回收的主要方法,重点阐述了偏光片、玻璃基板、液晶材料及金属铟资源化回收技术的最新研究进展,分析了研究工作在当前存在的问题,并展望了其在未来的发展方向。

Liquid crystal display is the important part of computers, televisions and mobile phones. Research on the resource recycling technology of waste liquid crystal display is of vital significance for the protection of environment and recycling of the valuable com- ponents. The main resource recycling technologies for each parts of the liquid crystal display are reviewed, with a focus on frontier resource recycling technologies of the primary components of liquid crystal display, including the polarizer, glass substrate, liquid crys- tal materials and indium. The problems in the current research work are analyzed and the development direction of the future research work is prospected.
