Optically compensated bend (OCB) mode liquid crystal display (LCD) panels are newly developed displays that have excellent moving picture quality, which is almost equivalent to that of a cathode ray tube (CRT). A high performance, with a brightness of 600 cd/m² and a contrast ratio of 600:1, was obtained by using the pseudo-impulse driving method to insert a black period between two continuous frames; further, the blinking backlight method was used. By measuring the centre of gravity of the human body, we compared statokinesigrams obtained from subjects viewing moving maps on OCBs and on conventional model displays. The results suggest that OCBs are better than conventional displays for scrolling map images such as those in car-navigation systems.
