The bottom fringe field is used to turn on the LC directors and the top fringe field is used to assist in the LC decay process. The decay time is reduced by ~2× compared to that of the conventional FFS mode between the full bright and dark states, and more than a 2× improvement is obtained for other gray-scale transitions. This CFFS mode also preserves the wide-view characteristics as the conventional FFS mode. Its applications to LCD TVs and monitors for reducing image blur are addressed.
