We have obtained high performance and low voltage driving OCB panel by reducing the critical voltage and retardation matching between liquid crystal layer and compensation films. Flattening color filter layer and optimizing rubbing process have minimized the critical voltage in the panel. In addition, an appropriate retardation of the film and LC layer has scanned to achieve low driving voltage and high transmission. Especially, by adopting new driving scheme, we considerably reduced the initial bend transition time, which is known as one of drawbacks in OCB mode. As a result, we developed the prototype 17" WXGA OCB panel with less than 5V drive, over 90% of TN light efficiency and over 80 degree for all viewing direction except for rubbing direction including color shift as well as high-speed response time.
