“…These attractive features make them more promising for practical applications. In addition, polymer-stabilized blue phase liquid crystal (BPLC) based on the Kerr effect [45][46][47][48][49][50] is emerging as a promising candidate for new photonics applications. The major attractions of BPLC are twofold: (1) submillisecond response time due to its self-assembled nanostructure [33,48,51], which is ~10× faster than that of NLCs and (2) free of a molecular alignment layer, which means a simpler fabrication process.…”

Electrically tunable liquid crystal microlenses have attracted strong research attention due to their advantages of tunable focusing, voltage actuation, low power consumption, simple fabrication, compact structure, and good stability. They are expected to be essential optical devices with widespread applications. However, the slow response time of nematic liquid crystal (LC) microlenses has been a significant technical barrier to practical applications and commercialization. LC/polymer composites, consisting of LC and monomer, are an important extension of pure LC systems, which offer more flexibility and much richer functionality than LC alone. Due to the anchoring effect of a polymer network, microlenses, based on LC/polymer composites, have relatively fast response time in comparison with pure nematic LC microlenses. In addition, polymer-stabilized blue phase liquid crystal (PS-BPLC) based on Kerr effect is emerging as a promising candidate for new photonics application. The major attractions of PS-BPLC are submillisecond response time and no need for surface alignment layer. In this paper, we review two types of fast-response microlenses based on LC/polymer composites: polymer dispersed/stabilized nematic LC and polymer-stabilized blue phase LC. Their basic operating principles are introduced and recent progress is reviewed by examples from recent literature. Finally, the major challenges and future perspectives are discussed.

“…To achieve it, only optimization of PS-BPLC material is not suitable for quite large Δε and Δn which leads poor reliability in active matrix LCDs. The groove-electrode was proposed and the higher its height was, the smaller the driving voltage of the PS-BPLC became [6] [7]. To distingish the height, newly wall-electrode which has higher height than the grooo-electrode was investigated.…”

“…However, high intrinsic birefringence, large dielectric anisotropy, and low viscosity are always in favor. Therefore, to better evaluate the performance of a BPLC material, a delicate balance between each parameter, such as operating voltage, transmittance and response time, should be taken into consideration [37][38][39][40].…”

The device physics and electro-optical properties of emerging liquid crystal displays (LCDs) based on the Kerr effect are investigated. With a voltage applied, both blue phase and polymer-stabilized blue phase exhibit a fascinating isotropic-toanisotropic transition. We have developed a numerical model to understand the underlying device physics in order to optimize device performance. The operating voltage is found to be inversely proportional to the square-root of Kerr constant of the LC composite. To reduce operation voltage while keeping high transmittance and fast response time, device structures with strong and deep horizontal electric fields, and LC materials with a large Kerr constant play equally important roles.
