How IPS Works

IPS LCD cell has two thin glass substrates between which the liquid crystal (LC) molecules are found. LC molecules are placed parallel to each other and the glass substrate. There are elctrodes in the lower glass substrate and when voltage is applied to it, a magnetic field is generated and the LC molecules arrange themselves accordingly in such a way that light can make its way and illuminate the pixels. The LC molecules can move freely at an angle of 90 degrees keeping themselves parallel to each other and the substrate. The viewing angle in LCD screens is affected by the arrangement of the LC molecules.
