It is a device that forms an electric field by applying a voltage to deform the arrangement of liquid crystal molecules, and thereby controls the light transmittance to express an image.

In developing a new liquid crystal display device to improve the image realization characteristics of the liquid crystal display device, computer simulation of the liquid crystal display device designed in the pre-production stage is urgently required in terms of research and development cost and time saving. have.

The liquid crystal display has an improved liquid crystal operating mode based on the concept of in-plane switching (IPS) mode, fringe-field switching (FFS) mode, and vertical alignment (VA) mode in order to have a large contrast ratio and to facilitate wide viewing angle.
