Abstract: Stereoscopic three-dimensional displays are classified into two types according to their operation principles. One type is based on binocular parallax. Eye-glasses/helmet stereoscopic displays and stereoscopic displays based on parallax barrier or lenticular belong to this type. Their technologies are relatively mature and corresponding productions are common. The other type is not based on binocular parallax. Holographic display, integral imaging display and volumetric display belong to this type. Their technologies are under development and corresponding productions are in lack. The device structures, operation principles and characteristics of the various stereoscopic displays were briefly expounded.

Key words: stereoscopic display, binocular parallax, holography, integral photography, volumetric display, autostereoscopic display

摘要： 按基本工作原理是否为双目视差将三维立体显示分为两大类。基于双目视差原理的三维立体显示主要有眼镜/头盔式立体显示和光栅式自由立体显示，这类三维立体显示的技术相对成熟并有相应产品；非基于双目视差原理的三维立体显示主要有全息立体显示、集成成像立体显示和体显示等，这类三维立体显示的技术较不成熟，大多没有相应产品。对这些三维立体显示的器件结构、工作原理以及各自的特性进行了阐述。
