“…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. Holographic display is considered as the ideal display method because it can faithfully reconstruct light wavefront with all correct depth cues.…”

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.

“…Over the past few years, we have developed three types of optically access-based volumetric display system using different screen mediums (solid, liquid and gas). In 2015, the first work on volumetric displays in our group demonstrated some important features, including a multilayer fluorescent solid screen for achieving a color display by changing the fluorescent material in each layer, and holographic parallel optical access via twophoton excitation for increasing the number of voxels per unit time [16]. The holographic parallel optical access was performed with a computer-generated hologram (CGH) displayed on a liquidcrystal spatial light modulator (LCSLM).…”

Abstract-Illumination optics in emerging naked-eye 3D display, especially in time-spatial multiplexing, or directional backlight naked-eye 3D display system, is systematically examined. Key issues in directional backlight system include: 1) Directional transmission of the left-and right-eye images to the corresponding viewing zone with small crosstalk; 2) The luminance on the screen should be homogeneous even for the viewers moving around. In this paper, we propose an adaptive optimization solution based on root mean square (RMS) for the design of illumination optics of the naked-eye 3D system. Based on the designed free-form backlight illumination, the overall design schemes for both single-user and multi-user naked-eye 3D display are proposed and demonstrated. By utilizing the novel dynamic synchronized backlight technique, the temporal crosstalk is effectively brought into control. The display defects such as the dark bands appearing at the joints of the lens array or at the middle of the Fresnel lens are simulated numerically and tested experimentally, hence providing effective design guidelines for the optical components as well as their fabrication error tolerance. Additionally, we propose a continuous backlight technique to improve the luminance homogeneity. Furthermore, a quantitative evaluation mechanism for the moiré pattern based on the Fourier analysis method, by introducing the contrast sensitivity function (CSF), is presented. A novel arrangement of a quasirandom RGB sub-pixel array is proposed to reduce the visibility of moiré pattern. As a result, full HD glassless 3D display suitable for glassless virtual and augmented realities is demonstrated with an unprecedented display quality.
