15.2: Distinguished Paper: A New Pixel Design and a Novel Driving Scheme for Multi-Domain Vertically-Aligned LCDs

A cost-effective wide-viewing-angle LCD mode, named Biased Vertical Alignment (BVA) mode, has been successfully developed by using a novel driving scheme and a new pixel design that adds a bias electrode and a bias TFT to the ordinary pixel structure. Compared to PVA and MVA modes, the BVA has a distinct advantage of lower manufacture cost due to the elimination of a lithographic process step to form either ITO-cuts or protrusions on the color-filter substrates. The 15″ BVA-mode XGA prototype exhibits a high contrast ratio of 1200:1 and high cell transmittance of 4.3 %.
