ABSTRACT
In-plane switching liquid crystal displays (IPS-LCDs) are widely applied in TFT-LCD for its excellent viewing angle and outstanding ability of color reproduction. However, its development in high-end LCDs is limited by its slow response. A fast response IPS-LCD with protrusion electrode is proposed in this paper, and its optical characteristics is simulated by TechWiz software. With the protrusion electrode, the driving voltage of IPS-LCD is reduced by 2.3 V. Although the driving voltage is reduced, the electric field in the liquid crystal layer is changed due to the electrode on protrusion, so the rise response speed is improved. In addition, the protrusion structure reduces the effective cell gap of the LC layer, and the decay time is proportional to the square of the cell thickness, so the decay response speed is also obviously improved. The whole response speed is improved by approximately 38% in contrast with the conventional IPS-LCD.
