Abstract
An in-plane-switching liquid crystal device based on uniform lying helix (ULH) alignment on polymerized surface is presented. We describe a liquid crystal (LC) mixture for flexoelecro-optic LC mode made from constituents with smaller and bigger flexoelectric coefficients and different temperature ranges of LC phases. The surface alignment is formed by polymerizing a minute amount of a reactive monomer in a liquid crystal host to form nano-sized polymer fibers on the two substrates of the cell. The short-pitch cholesteric comprises of a dual-frequency nematic liquid crystal, a twist-bend nematic liquid crystal and a chiral dopant. Substantial improvements in electro-optical properties such as large field-induced tilt angle (> 45°) and fast response time (∼100 µs) have been achieved. We will also present the analytical results of flexoelectric behavior and morphological properties of the polymer stabilized ULH.
