LED液晶背光源因其色彩还原性好、功耗低、寿命长等优势,近年来发展迅猛,在手机、笔记本电脑、高清电视等显示领域的渗透率近100%。广色域、高清、大尺寸是新型显示领域的主要发展趋势。目前广色域LED背光源显示的主流实现方式是"蓝光芯片+绿粉+红粉",红粉是决定显示色域的关键因素。本文详细介绍了氟化物系列红色荧光粉的研究进展、市场前景、专利情况,并进一步指出该系列荧光粉目前存在的问题,以及未来发展趋势,以满足广色域、高稳定性显示的应用需要。
Abstract:Much development have been made in the field of LED backlight for LCD in recent years,due to its good color reproduction,low power consumption and long life,etc. It provides about 100% penetration rate in the display area,such as mobile phones,laptops and high definition televisions. Wide color gamut,high definition and large size are the main development trends in the novel display area.Presently,the main way to realize the wide-color-gamut LED backlight display is " blue chips + green phosphor + red phosphor",of which the color gamut largely depends on red phosphor. In this paper,the research progress,market prospect and patent situation of fluoride red phosphors are discussed in detail. Furthermore,the current problems and future trends of fluoride red phosphors are analyzed for the application requirements of wide-color-gamut and high-stability display.
