Abstract

An in-plane switching mode super twisted nematic liquid crystal device with the wide viewing angle characteristics and fast response speed is proposed. Electric filed is applied in the plane of the substrates, unlike a conventional super twisted nematic (STN) mode. The compensation films were used in this mode for obtaining the black/white mode with very small color shift. Compared with the normal in-plane-switching mode and in-plane-switching mode twist nematic configuration, its response speed is improved four times on not only the rise time but the decay time. With the compensation film, the excellent viewing angle, weak color shift can assimilate with that of normal IPS mode. The fast response speed will be useful in designing the video-response liquid crystal displays.
