51‐2: Multi‐image Plane Display based on Polymer‐stabilized Cholesteric Texture

Abstract

A multi-image-plane display based on cascaded switchable polymer-stabilized cholesteric texture (PSCT) screens is demonstrated. The unique features of our PSCT screens are twofold: transmittance is 98.2% at voltage-off state and switching time is around 1 ms. Potential applications include wearable virtual reality, augmented reality, and other headmounted displays.

Multiplane displays based on liquid crystals for AR applications

“…The key components of multiplane displays using the time‐multiplexing method are fast tunable optical devices, such as liquid lens, deformable mirror, and liquid crystal (LC) devices . For instance, Hua et al realized a multiplane optical see‐through (OST) AR display utilizing a tunable liquid lens.…”

“…Tunable LC lenses (eg, LC refractive lens and LC Pancharatnam‐Berry [PB] lens) are employed in AR displays, to control the distance of virtual images by varying their focal lengths. And in some displays, multiple LC scattering shutters are used as the display medium …”

“…The key components of multiplane displays using the time-multiplexing method are fast tunable optical devices, such as liquid lens, 24 deformable mirror, 25,26 and liquid crystal (LC) devices. [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] For instance, Hua et al realized a multiplane optical see-through (OST) AR display utilizing a tunable liquid lens. As the focal length of the liquid lens is varied with external voltage, the image of the display panel can be formed at different depth at different moment.…”

“…And in some displays, multiple LC scattering shutters are used as the display medium. [30][31][32]39 In the following sections, we first introduce the working principle of multiplane AR displays and then focus on two types of multiplane AR displays based on LCs. The first one is realized by sequentially switching fast polymer stabilized LC (PSLC) scattering films to form the multiplane display medium.…”
