“…To mitigate the motion artifacts in VR headsets, display with high frame rate (≥120 Hz) and low duty ratio (≤20%) are preferred 54 , 55 . Therefore, the LC response time should be fast enough to support the high frame rate and low duty ratio 56 – 62 . To achieve a response time faster than 3 ms, the standing layer approach (also known as dead zones) has been demonstrated.…”

Liquid crystal displays (LCDs) and photonic devices play a pivotal role to augmented reality (AR) and virtual reality (VR). The recently emerging high-dynamic-range (HDR) mini-LED backlit LCDs significantly boost the image quality and brightness and reduce the power consumption for VR displays. Such a light engine is particularly attractive for compensating the optical loss of pancake structure to achieve compact and lightweight VR headsets. On the other hand, high-resolution-density, and high-brightness liquid-crystal-on-silicon (LCoS) is a promising image source for the see-through AR displays, especially under high ambient lighting conditions. Meanwhile, the high-speed LCoS spatial light modulators open a new door for holographic displays and focal surface displays. Finally, the ultrathin planar diffractive LC optical elements, such as geometric phase LC grating and lens, have found useful applications in AR and VR for enhancing resolution, widening field-of-view, suppressing chromatic aberrations, creating multiplanes to overcome the vergence-accommodation conflict, and dynamic pupil steering to achieve gaze-matched Maxwellian displays, just to name a few. The operation principles, potential applications, and future challenges of these advanced LC devices will be discussed.

“…Such a fast response time can be achieved by using a thin cell gap, low viscosity LC material, or the overdrive method. [76][77][78] Here, we take a display with 120-Hz frame rate as an example to compare the MPRT of the three display technologies. If the LC response time is faster than 2 ms, the MPRT of the TFT LCD is almost the same as that of OLED and μLED displays.…”

Recently, "liquid crystal display (LCD), organic light-emitting diode (OLED), or micro-light-emitting diode (LED): who wins?" is a heated debatable question. In this review article, we provide a comprehensive overview of these three promising display technologies through nine display performance indicators, including ambient contrast ratio, motion picture response time, viewing angle and angular color shift, color gamut, resolution density, power consumption, cost, lifetime, and thin profile and panel flexibility. The advantages and disadvantages of each technology are analyzed, and their future perspectives are discussed.
