摘要

Carbon nanotube-based field emission display (CNT-FED)possesses many advantages such as low operating vol-tage,low power consumption,low manufacturing cost,and so on.In the past decades,research and application development of CNT-FED have become one of the hot topics in the field of display technology,and considerable achievements have been accumulated. After a brief review of the mechanism of carbon nanotubes for field emission and advantages of carbon nanotubes for FED,some pro-gress on FED research and some problems to be solved are introduced,including preparation of carbon nanotube cathode films,im-provement of working stability and lifetime of carbon nanotube cathode,and the design of cathode structure.Finally,we discuss the development prospects of carbon nanotubes for FED.%碳纳米管场发射平面显示器具有工作电压低、功耗低和制造成本低等优势，近年来基于碳纳米管场发射平面显示器的研究与应用研发已成为显示技术领域研究的热点之一，并已取得丰富成果。简要回顾了碳纳米管用于场发射的机理以及用于场发射平面显示器的优势，主要介绍了碳纳米管用于场发射平面显示器研究的一些进展和一些亟待解决的问题，包括碳纳米管阴极薄膜的制备、碳纳米管阴极工作稳定性与寿命的改进以及阴极结构的设计等，并展望了碳纳米管用于场发射平面显示器的发展前景。
