Light field displays can display three-dimensional (3D) images with smooth motion parallax without the use of special glasses, by reproducing light ray information from objects. Because of this feature, light field displays can be applied in a wide range of fields, and various 3D display methods based on light field reproduction have been researched and developed. These methods can be classified into two types based on binocular parallax: horizontal and full parallax. In this study, we mainly discuss the integral 3D display, Aktina Vision, and compressive light field display, which can display full-parallax 3D images while also discussing horizontal parallax display methods. The basic principles and system configurations of each method are explained, and their characteristics and problems are discussed. In addition, the latest research on techniques to improve the display characteristics of 3D images is presented, such as display methods using multiple display devices or time-division multiplexing.

光场显示器可以通过再现物体的光线信息，在不使用特殊眼镜的情况下显示具有平滑运动视差的三维 (3D) 图像。由于这一特点，光场显示可以应用在广泛的领域，基于光场再现的各种3D显示方法已经被研究和开发。这些方法可以根据双眼视差分为两种类型：水平视差和全视差。在本研究中，我们主要讨论集成 3D 显示、Aktina Vision 和压缩光场显示，它们可以显示全视差 3D 图像，同时也讨论水平视差显示方法。解释了每种方法的基本原理和系统配置，并讨论了它们的特点和问题。此外，
