“…The multi-plane displays generate multiple 2D images positioned at different planes within the volume. This method provides the acceptable accommodation cues and solves the VAC problem in conventional 3D displays [19][20][21]. The straightforward way to achieve a multi-plane display involves utilizing a stack of transparent displays in space [22].…”

In recent years, the emergence of virtual reality (VR) and augmented reality (AR) has revolutionized the way we interact with the world, leading to significant advancements in 3D display technology. However, some of the currently employed 3D display techniques rely on stereoscopic 3D display method, which may lead to visual discomfort due to the vergence-accommodation conflict. To address this issue, several true 3D technologies have been proposed as alternatives, including multi-plane displays, holographic displays, super multi-view displays, and integrated imaging displays. In this review, we focus on planar liquid crystal (LC) devices for different types of true 3D display applications. Given the excellent optical performance of the LC devices, we believe that LC devices hold great potential for true 3D displays.

“…[30] has further extended this for the waveband tunability as well as the light‐induced phase profile flippability of a reflective LC‐GPOE via the photoinvertible chiral superstructure. Yet, none of the aforementioned studies investigate the helicity modulation of a transmissive LC‐GPOE that has currently found many applications in augmented reality display, [ 38 ] light detection and ranging (LiDAR), [ 39 ] laser beam shaping, [ 40 ] etc. Moreover, the response of LC orientation is discretized in refs.…”

The ability to establish significant phase modulation at low applied field provides a promising route toward polarization control and wavefront shaping for liquid‐crystal‐based devices. Owing to the polarization‐selective reflectivity of chiral liquid crystals (CLCs), reflective wavefront shaping via geometric phase is demonstrated when a circularly polarized light is Bragg reflected by a spatially orientated chiral layer. Nowadays, photoresponsive CLCs have attracted extensive attention due to their exotic feature that endows the CLC devices with the capability of electric‐free remote control. Despite the mature photoresponsive CLC materials and the sophisticated reflective geometric phase devices, a light‐induced topological optical phase modulation for a transmissive wave exiting a CLC cell remains elusive. Here, with the employment of a photosensitive chiral dopant, a hybrid aligned photoresponsive CLC system, demonstrating the simultaneous light modulation of topological geometric phase and dynamic phase via helical pitch manipulation is established. The continuous dual‐phase modulation engenders a smooth optically controllable diffraction efficiency (i.e., from <5% to >90%) of the proposed light‐reconfigurable CLC geometric phase optical element prototypes with multistable diffractive behavior, thus launching a paradigm shift for the application of novel liquid‐crystal photonic devices in the field of all‐optical polarization and spin processing.

“…After further research, he discovered that this cloudy liquid was tissue orientated and birefringent; this liquid is now widely used as a "liquid crystal" (LC). As LC materials entered the display industry and other application fields in the late 1960s, LC science and its application research entered a stage of comprehensive development [4][5].…”

Liquid crystal (LC) is an intermediate state compound between liquid and crystal, which has the anisotropy of crystal molecules while having the fluidity of liquid. It is a cutting‐edge technology in optoelectronics. LC lens is an electrically controlled focusable gradient refractive index lens. In light field displays, LC lenses with diameters in the millimetre range can cover more areas. Therefore, we propose a large aperture (LA) liquid crystal (LC) lens with an electrically controlled focal length of 4 mm in diameter. LC lenses with large apertures require large voltages and there are certain safety issues and equipment requirements. We have therefore utilised a triboelectric nanogenerator (TENG) that can harvest energy from the environment and convert it into usable electrical energy. TENG has the advantages of being small and portable and enables the use of renewable energy. In this paper, we propose a new type of feather TENG (F‐TENG) with a positive friction electrode of feathers and a negative electrode of polytetrafluoroethylene (PTFE) mixed with graphene, which enables the use of F‐TENG to power LC lens systems, thus providing a new application idea for the display field.
