“…For passive driving, the response time is determined by the polarization rotator. A thin TN polarization rotator can have a response time of 2 ms [41], while a ferroelectric polarization rotator usually has a response time of around 0.1 ms [42]. The major di erence is that TN is a broadband polarization rotator.…”

Abstract:In this review paper, we report recent progress on Pancharatnam-Berry (PB) phase optical elements, such as lens, grating, and de ector. PB lenses exhibit a fast switching time between two or more focal lengths with large diopter change and aperture size, which is particularly attractive for addressing the accommodation mismatch in head-mounted display devices. On the other hand, PB gratings and de ectors o er a large-angle beam de ection with wide acceptance cone and high e ciency, as compared to conventional volume gratings. Such merits provide great advantages for waveguide-coupling augmented reality headsets. Moreover, the thickness of PB optical elements is only a few micrometers, thus they can be conveniently integrated into modern wearable display systems.

“…In order to display more continuous 3D scenes, various fast‐response LC devices have been proposed to act as the tunable devices in AR displays. For example, a thin‐cell TN device with response time of approximately 2 ms has been used in polarization multiplexing multiplane AR displays as a broadband polarization rotator . Wu et al used a tunable PB LC lens that can achieve a response time as fast as 0.7 ms in their AR display system .…”

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.

“…To achieve wide view while maintaining high transmittance, another option is to use single-domain VA with directional backlight and a diffusive element [16]. [17]. The rise time is 0.66 ms and the decay time is 2.04 ms. With overdrive scheme, the average gray-to-gray response time is 1.95 ms. With such fast response time, the MPRT is comparable to the limiting MPRT (W = 0), as shown in Fig.…”
