Multiplane displays are capable of displaying 3D scenes with correct focus cues by creating multilayer 2D images in the display volume. Hence, such a 3D display technique could effectively address the accommodation‐vergence conflict (AVC) problem, which is prevalent in augmented reality (AR) displays. In this paper, we review the recent progress on multiplane AR displays based on liquid crystals (LCs) for AR applications. The working principle of multiplane AR displays is illustrated, the electro‐optical properties of the tunable LC devices are investigated and display prototypes are demonstrated. Finally, we discuss the prospects and challenges of multiplane AR displays based on LCs.

用于AR应用的基于液晶的多平面显示器

通过在显示空间中创建多层2D图像，多平面显示器能够显示具有正确焦点提示的3D场景。因此，这种3D显示技术可以有效解决适应性-收敛冲突（AVC）问题，这在增强现实（AR）显示中很普遍。在本文中，我们回顾了基于AR的液晶（LC）的多平面AR显示器的最新进展。阐述了多平面AR显示器的工作原理，研究了可调LC器件的电光特性并演示了显示器原型。最后，我们讨论了基于LC的多平面AR显示器的前景和挑战。
