介绍双稳态显示器件的原理，推广双稳态显示技术的意义和基本思路。在此基础上简要介绍现有比较成熟的几种双稳态显示器件的基本原理、基本特性、研究进展和存在的问题，包括以液晶材料为核心的双稳态器件、基于光干涉与机械双稳态机构的iMod显示器件、基于电泳现象的零电场双稳态E-ink显示器件。由于双稳态发展历史已经很长，本篇综述的宗旨不在于介绍最新的发展状况，而在于为双稳态显示器件提供较为完整的创造思想和方法。在液晶显示单元双稳态化的基础上，作者提出OLED阵列、FED阵列的双稳态结构的原理与技术途径。提出通过现有技术的组合，实现显示器件双稳态化的大屏幕显示器件的发展思路。

The principle of the bistable display device, the significance of bistable display technique and the basic clue were introduced in the paper. Based on above knowledge, the current bistable display devices and its principle, research headway and existent problem were presented, including the bistable devices based on liquid crystal, based on combination of light interference and bistable mechanic display device (iMod), base on electrophoresis of zero electric field bistable E-ink display device.Due to history of development of bistable display device is quite long, Purpose of the overview is not only introduce the status of the field, moreover, purpose of the overview is to provide the creative ideas and the solutions for bistable display device.On the foundation of bistable idea, the bistable structure of OLED array, of FED will be presented. By combination of existed technology, the clue of development of large screen display by bistable technology is presented.
