Novel Multi-Domain Twisted Nematic Mode Liquid Crystal Display

This paper proposed a wide viewing angle twisted nematic(TN) liquid crystal display(LCD) with a protrusion structure under the pixel electrode.The proposed LCD mode avoids the complex rubbing processes because of the protrusion which induces the multi-domain structure like the conventional multi-domain TN mode.As no voltage applied,the LC profile is the same as that of the normal TN cell,the LC molecules tilted four different directions to obtain the multi-domain structure while the operate voltage is applied.In this paper,the electro-optic characteristics is simulated using the professional software,and the results show that the proposed multi-domain TN LCD has the wide viewing characteristics and low color shift.
