摘要:: 照明一直是我国能源领域的消费大户，寻找高效健康的白光光源一直是照明行业的重要任务。有机发光二极管（OLED）自1987年被柯达公司的邓青云博士提出以来，经过了数十年的发展目前已经在小尺寸显示领域得到了广泛的应用和市场的认可。在照明领域，白光有机发光二极管（WOLED）也以其高性能、可弯曲、面光源、无蓝害等一系列优势受到人们越来越多的重视，是未来新型固态照明光源的有力竞争者。随着OLED技术的深入发展，WOLED近年来已经得到了理论、技术、应用等多方面发展，而且取得了重要成果。综述了近期WOLED的设计方法、主要进展以及所面临的问题，主要从全荧光WOLED、全磷光WOLED和杂化WOLED三种器件构筑方法对WOLED进行了概述。

Abstract:: The lighting industry is always a major consumer in China’s energy sector. Finding efficient and healthy white light sources has always been an important task in the lighting industry. Since the introduction of Dr. CW Tang from Kodak in 1987, organic light-emitting diodes (OLEDs) have been widely used in the field of small-size displays and approved by the market after decades of development. In the field of lighting, white organic light-emitting diodes (WOLEDs), strong competitor for new solid-state lighting sources in the future, are also receiving more and more attention for their high performance, flexibility, surface light source, and blue-damage-free. With the in-depth development of OLED technology, white organic light-emitting diodes have been developed in many aspects in theory, technology, application, etc., and have achieved many important results. This paper reviews the recent design methods, major developments, and problems faced by white organic semiconductors. In this paper, white organic light-emitting diodes are mainly summarized from three kinds of device construction methods: full-fluorescence WOLEDs, all-phosphor WOLEDs, and hybrid WOLEDs.
