IPS LCD

conventional liquid crystal modes such as twisted nematic (TN) have problems such as brightness changing color shift according to viewing angle. In TN mode, liquid crystal molecules stand up when a voltage is applied. When the liquid crystals are in the upright position, their optical properties vary significantly depending on the viewing angle. This causes the color and brightness of different viewing angles to change. In in-plane switching (IPS) mode, liquid crystal molecules rotate parallel to the panel. This means that changes depending on the perspective are limited. Therefore, IPS LCDs provide limited brightness and color changes to produce high-quality images without considering viewing angles.
