Fast-Response and High-Contrast OCB LCD with LED Backlight

Abstract

We have developed an optically compensated bend (OCB) LCD (“OCB-III”) that incorporates an LED blinking backlight. The OCB-III combines OCB with LEDs and thus has fast response characteristics. We demonstrated on a 9-inch WVGA OCB-III panel that the OCB-III has a fast MPRT (4.7 msec) and high contrast ratio (1000:1). This performance is almost comparable to that of a CRT. We expect the OCB-III to have various applications, such as in televisions, professional-standard displays, automobiles, and mobile devices.
