Axially symmetric aligned microcell (ASM) mode: Electro‐optical characteristics of new display mode with excellent wide viewing angle

Abstract

Abstract— The new LCD display mode (ASM mode) which has the axially symmetric orientation of liquid crystal molecules and the micro‐cell structure corresponding to each pixel is described in this paper. The electro‐optic characteristics of this mode afford high contrast (CR ≥ 200, at normal direction) and the wide viewing angle characteristics without contrast inversion (±60° in both up‐down and left‐right directions).

Control of Morphology and Alignment of Liquid Crystal Droplets in Molecular-Aligned Polymer for Substrate-Free Displays

“…Afterwards, the LC cell was irradiated by UV light through a patterned photomask. We consider that the polymer was precipitated on the UV-irradiated area and LC droplets were precipitated at any position as a result of the UV light exposure of the LC cell through a patterned photomask [7]. In addition, it is expected that the molecular alignment of the LC will be maintained by the anchoring force of the polymer surface [8].…”

Optical Photopolymers: Design and Applications

“…[21] Approaches using a combination of dichroic mirrors, micro-optics, and a single LCD panel have been successfully applied to this problem but issues of the high cost of dichroics and sensitive alignment of the components remain. [22] Approaches using pixellated holograms have been demonstrated using diffractive or holographic components to replace the color filters and significantly improve (factor of 2±4) the light throughput of the overall system. [21,23,24] Recently, holographic approaches to more effective light management have been discussed for backlit LCDs [25] and reflective LCDs.…”

A Low Operating Electric Field Blue-Phase Liquid Crystal Display With Wedge Protrusion

“…The wedge protrusion can support the thin electrode which is stable comparing with the inclined electrodes. To fabricate such wedge-shaped electrodes, a layer of organic polymer with a height larger than 5 m is coated on substrate [9], [26], the unwanted areas are 1551-319X © 2014 IEEE.
