Novel Electrode Design for High Transmittance In-Plane Switching (HT-IPS) LC Cell

摘要

This paper proposes a novel hexagonal electrode structure for optimal operation of the in-plane switching (IPS) mode liquid crystal cell. The proposed electrode architecture was designed in an effort to ensure the enhanced light transmittance and wider viewing angle characteristics as well as reduced color shift. We looked into the dynamic response of LC molecules and the consequent light transmission behavior under the electric field with a three-dimensional finite element method simulator. Our numerical study indicate that the proposed IPS cell with hexagonal electrode structure exhibits a higher peak transmittance over the conventional IPS architecture such as super-in-plane switching (S-IPSJ mode. Our simulation revealed that a design optimization is needed due to the increase of threshold voltage despite the increase of the peak light transmittance.
