He conducted a pioneering study for understanding motion image degradation mechanisms in flat panel displays and for proposing methods to reduce these problems, based on display device technology and vision science. As the result, he made a significant contribution to motion image quality improvement of active-matrix FPDs, such as LCDs and OLEDs. The research has exerted potent influence to design of current LCD-TV and OLED products, such as 120 Hz or 240 Hz driving, black insertion and scanning backlights.
