“…To effectively address the accommodation-vergence conflict (AVC) problem, various display techniques have been proposed for AR applications, including integral imaging display, 4,[8][9][10][11] holographic display, 12,13 supermutiview display, 14,15 and volumetric display. [16][17][18][19][20][21][22][23] Integral imaging display can also provide correct accommodation depth cue by generating numerous elemental images with a microlens array, but the spatial resolution of the 3D images is greatly reduced.…”

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.

“…A full-parallax hologram with a resolution of 20,000 × 20,000 can be up to 32.9 hours. Another rectangular tiling based algorithm is integral holography, which is the combination of integral imaging 3D display and holography [21][22][23][24]. In this method, each element light field image (EI) rendered from a micro-lens array or pinhole array is firstly fast Fourier transformed (FFT) as the complex amplitude of each elemental hologram or called hogel.…”

A fast calculation method for the full parallax high-resolution hologram is proposed based on the elemental light field image (EI) rendering. A 3D object located near the holographic plane is firstly rendered as multiple EIs with a pinhole array. Each EI is interpolated and multiplied by a divergent sphere wave and interfered with a reference wave to form a hogel. Parallel acceleration is used to calculate the high-resolution hologram because calculation of each hogel is independent. A high-resolution hologram with the resolution of 20,0000×20,0000 pixels is calculated only within 8 minutes. Full parallax high-resolution 3D displays are realized by optical reconstructions.

“…Lee et al released a 2D/3D hybrid integral imaging display system by using fast switchable hexagonal liquid crystal lens array [5]; Wang et al developed a convertible 2D/3D display using an edge-lit light guide plate based on integral imaging [8]; Oh et al released a 3D/2D convertible integral imaging display system using an active mask [9]; However, theses 2D/3D compatible display methods or systems cannot be applied to augmented reality. In order to realize the see-through 2D/3D compatible display, we reported a 2D/3D convertible display based on integral imaging by using holographic optical element and polymer dispersed liquid crystal [10], but 2D and 3D contents cannot be displayed simultaneously.…”

A see‐through 2D/3D compatible display based on integral imaging is proposed. It consists of a lens‐array holographic optical element (LAHOE) film, a polymer dispersed liquid crystal (PDLC) film and two projectors. The see‐through projection screen is composed of the LAHOE film and the PDLC film. The PDLC film is tightly behind the LAHOE film. With applied voltage, the projection screen works in the transparent display mode. 3D image for Bragg matched image can be presented, and 2D image can also be presented.
