液晶显示面板用薄型玻璃导光板国内外研究进展

Research Development on Thin Glass Light Guides for Liquid Crystal Display Panels at Home and Abroad

导光板是液晶显示器(LCD)重要光学部件之一,对背光(BL)均匀性起着重要作用。结合导光板(Light guide plate,简称LGP)材料发展历史、产品性能及应用需求,分析了大尺寸液晶显示屏从PMMA(亚克力)导光板发展成玻璃导光板的必要性,通过对技术改进后的导光板性能发展变化的评价,介绍玻璃导光板主要存在的问题和发展趋势,综述玻璃导光板国外研发生产进展情况以及国内外导光板基础研究状况,为我国研发玻璃导光板提供借鉴作用。

Light guide plate(LGD)is one of the most significant optical component part for liquid crystal display(LGD),and it plays an important role in backlight(BL)uniformity.Combines the background of product development,performance and application requirements of light guide plate to analyze the necessity of developing large-size LCD screen from PMMA LCD to glass LCD.It also evaluates the change in performance of the new improved LGP,identify the main problems and development trends,as well as reviews the progress and development of foreign research,which provides a reference for the development of glass light guide plate in China.
