The physical world around us is three-dimensional (3D), yet traditional display devices can show only two-dimensional (2D) flat images that lack depth (i.e., the third dimension) information. This fundamental restriction greatly limits our ability to perceive and to understand the complexity of real-world objects. Nearly 50% of the capability of the human brain is devoted to processing visual information [ (Pearson, 2012)]. Flat images and 2D displays do not harness the brain's power effectively. With rapid advances in the electronics, optics, laser, and photonics fields, true 3D display technologies are making their way into the marketplace. 3D movies, 3D TV, 3D mobile devices, and 3D games have increasingly demanded true 3D display with no eyeglasses (autostereoscopic). Therefore, it would be very beneficial to readers of this journal to have a systematic review of state-of-the-art 3D display technologies.
我们周围的物理世界是三维（3D）的，但传统显示设备只能显示缺乏深度（即第三维）信息的二维（2D）平面图像。这一基本限制极大地限制了我们感知和理解现实世界物体复杂性的能力。人类大脑近50%的能力用于处理视觉信息[（皮尔逊，2012年）]。平面图像和2D显示器无法有效地利用大脑的能力。随着电子、光学、激光和光子学领域的迅速发展，真正的3D显示技术正在进入市场。3D电影、3D电视、3D移动设备和3D游戏越来越需要无需眼镜的真正3D显示（自动立体显示）。因此，对本期刊的读者来说，系统回顾最先进的3D显示技术将非常有益。
