IPS LCD

Conventional liquid crystal modes such as twisted nematic (TN) have problems such as brightness change an color shift depending on the viewing angle. In TN mode, liquid crystal molecules stand up as a voltage is applied to them. When liquid crystals are in an upright position, their optical characteristics vary significantly depending on the viewing angle. This results in variation in color and brightness from different viewing angles. In in-plane switching (IPS) mode, liquid crystal molecules rotate in parallel with the panel. This means that the variation depending on the viewing angle is limited. Therefore, IPS LCD provides limited changes in brightness and color irrespective of the viewing angle to produce high image quality.
