表面传导电子发射显示器件概述及研究现状

表面传导电子发射显示（SED）是一种新型平板显示技术,跟现有主流显示技术相比,它在对比度、灰度级、色彩、动态响应及功耗等方面均有优势。本文在简单叙述了SED的发展历史、原理及结构之后,重点介绍了SED的技术核心——电子发射源的结构、各种工艺流程及最新进展,最后是对SED的性能和特点的简介以及市场展望。

A Summary and Research Situation of Surface-Conduction Electron-Emitter Display

Surface-conduction electron-emitter display（SED） is a new kind of flat panel display technology.Compared with the existing main stream technology,the SED has great advantage in many aspects such as contrast,gradation levels,colors,dynamic response as well as power consumption.In this article,after presenting the development history,the principles and main structure of SED in brief,the structure,various process flows and latest developments about the surface conduction electron-emitter,which is the core technology of SED,are demonstrated emphatically,followed by the performances,characteristics and marketing foreground of SED in the end.
