High-transmittance pixel- and common-electrode structures design for in-plane switching mode with low crosstalk

Abstract

The replacement of cathode ray tube (CRT) by thin-film-transistor liquid-crystal display (TFT-LCD) in TV applications requires the implementation of LC modes with wide viewing angles and excellent video display quality. Although the in-plane switching (IPS) mode has been known as an excellent technology for realizing wide viewing angles, it has a low aperture ratio that has been improved by Advanced Super-IPS (AS-IPS). In this paper, we propose a novel electrode structure that not only increases substantially the aperture ratio of the current AS-IPS but also reduces the crosstalk in terms of a capacitive coupling ratio from 1.2% to 0.05%.
