Modeling of Blue Phase Liquid Crystal Displays

Vertical field switching for blue-phase liquid crystal devices

“…Polymer-stabilized blue-phase liquid crystal (PS-BPLC) 1,2 is emerging as next-generation display and photonic technology because it exhibits some revolutionary features, e.g., no need for alignment layer, fast response time, and isotropic dark state. So far, the majority of previously demonstrated bluephase liquid crystal (BPLC) devices utilize in-plane switching (IPS) electrodes [3][4][5][6] in which the electric field is mainly in lateral direction and the Kerr effect-induced birefringence is along the electric field if the employed BPLC has a positive dielectric anisotropy (De > 0). 7 Therefore, the backlight can be easily set at normal incidence.…”

Modes for Liquid Crystal Devices

“…However, due to the narrow pre-transitional operating temperature range of nematic liquid crystals and despite very fast response, nematic liquid crystal displays based on the Kerr effect were only of scientific interest at the time [22]. In retrospective it is interesting to note the recent renewed interest in LCDs based on the Kerr effect [23] which is spurred by remarkable progress made with blue-phase liquid crystals and display geometrics [23][24][25] [26]. In collaboration with medical research he discovered correlations between neurotransmitter transport, selective ion conduction across ionophore-doped cell membranes, and heart activity [27].…”

Emerging Liquid Crystal Displays Based on the Kerr Effect

“…Our group has developed a 3-D numerical model to calculate the electro-optic properties of blue-phase LCDs [29,30], or more generally speaking, a device involves isotropic-to-anisotropic transition based on Kerr effect. Here we briefly outline our approaches as follows.…”
