“…The total focal length of the LC lens is composed of two sublenses: one is the LC layer and the other is the concave glass lens. The total focal length of the LC lens (f(V)) can be written as [12][13][14][15][16][17][18][19]:…”

Electrically tunable focusing liquid crystal (LC) lenses are reviewed in this paper. The distribution of the orientations of LC directors which is controlled by electric fields results in a distribution of refractive indices of LC directors. The incident light can be modulated by the electrically tunable lens-like phase difference of the LC lens. We introduce the basic operating principles of LC lenses and discuss the structures of LC lenses. The major challenges of LC lenses are also discussed. We believe this paper provides a guideline for basic understanding of LC lenses.

“…But high Δn LC materials are usually associated with high viscosity or UV stability problem, whereas thick cell gap leads to high driving voltage and slow response time. [23][24][25][26] Here, we propose a polymeric lens to overcome the tradeoff between driving voltage, response time, and focusing power. 16 …”

Three-dimensional (3D) display has become an increasingly important technology trend for information display applications. Dozens of different 3D display solutions have been proposed. The autostereoscopic 3D display based on lenticular microlens array is a promising approach, and fast-switching microlens array enables this system to display both 3D and conventional 2D images. Here we report two different fast-response microlens array designs. The first one is a blue phase liquid crystal lens driven by the Pedot: PSS resistive film electrodes. This BPLC lens exhibits several attractive features, such as polarization insensitivity, fast response time, simple driving scheme, and relatively low driving voltage, as compared to other BPLC lens designs. The second lens design has a double-layered structure. The first layer is a polarization dependent polymer microlens array, and the second layer is a thin twisted-nematic (TN) liquid crystal cell. When the TN cell is switched on/off, the traversing light through the polymeric lens array is either focused or defocused, so that 2D/3D images are displayed correspondingly. This lens design has low driving voltage, fast response time, and simple driving scheme. Simulation and experiment demonstrate that the performance of both switchable lenses meet the requirement of 3D display system design.

“…L iquid crystals (LCs) have optical properties such as large birefringence and dielectric anisotropy. LC materials have been extensively used in display devices and some optical tunable applications such as millimeter order-diameter lenses, [1][2][3][4][5][6][7][8][9] microsized array lenses, [10][11][12] spatial light modulators 13) and photonic crystal fiber couplers. 14) In our group, many types of simple LC lenses with a single circularly hole-patterned electrode for controlling focal length have been reported.…”

A liquid crystal (LC) device with double circularly hole-patterned electrodes and an external flat electrode is developed to improve the range of negative lens power. The negative lens power can be improved by applying the voltage to the additional new hole-patterned electrode. The lens power of the LC device with the double circularly hole-patterned electrodes is about threefold as large as that of the conventional LC device with a single hole-patterned electrode.
