Background

The LCD is constructed by placing liquid crystal in two parallel glasses, and many vertical and horizontal fine wires are arranged between the two glasses, and the direction of rod-like crystal molecules is controlled by electrifying or not, so that light is refracted out to generate pictures. The grooves in the two planes are perpendicular to each other, i.e., if the molecules in one plane are aligned north-south, the molecules in the other plane are aligned east-west, and the molecules between the two planes are forced into a 90 degree twisted state. Since light travels in the direction of alignment of the molecules, the light is also twisted by 90 degrees as it passes through the liquid crystal. However, when a voltage is applied to the liquid crystal, the molecules are vertically rearranged, so that the light can be directed out without any twist.
