The autostereoscopic display is a promising way towards three-dimensional-display technology since it allows humans to perceive stereoscopic images with naked eyes. However, it faces great challenges from low resolution, narrow viewing angle, ghost images, eye strain, and fatigue. Nowadays, the prevalent liquid crystal display (LCD), the organic light-emitting diode (OLED), and the emerging micro light-emitting diode (Micro-LED) offer more powerful tools to tackle these challenges. First, we comprehensively review various implementations of autostereoscopic displays. Second, based on LCD, OLED, and Micro-LED, their pros and cons for the implementation of autostereoscopic displays are compared. Lastly, several novel implementations of autostereoscopic displays with Micro-LED are proposed: a Micro-LED light-stripe backlight with an LCD, a high-resolution Micro-LED display with a micro-lens array or a high-speed scanning barrier/deflector, and a transparent floating display. This work could be a guidance for Micro-LED applications on autostereoscopic displays.
自动立体显示器是三维显示技术的一种很有前景的方式,因为它能让人们用肉眼感知立体图像。然而,它面临着来自低分辨率、窄视角、重影、眼睛疲劳等方面的巨大挑战。如今,普遍使用的液晶显示器(LCD)、有机发光二极管(OLED)以及新兴的微型发光二极管(Micro-LED)提供了更强大的工具来应对这些挑战。首先,我们全面回顾自动立体显示器的各种实现方式。其次,基于LCD、OLED和Micro-LED,比较它们在实现自动立体显示器方面的优缺点。最后,提出了几种基于Micro-LED的自动立体显示器的新颖实现方式:一种带有LCD的Micro-LED光条背光源、一种带有微透镜阵列或高速扫描屏障/偏转器的高分辨率Micro-LED显示器以及一种透明浮动显示器。这项工作可为Micro-LED在自动立体显示器上的应用提供指导。
