Abstract
AbstractThis paper presents novel LED backlight driving technology with a fully embedded LED driver LC. This driving system and IC feature a high speed Reduced Swing Differential Signaling (RSDS) interface, an independent PWM controller with high resolution programming, and embedded scan logic. To get high efficiency from the boost converter, highly advanced dynamic headroom control technology has been implemented onto the IC. The embedded current boosting function showed almost no brightness reduction when operated in scanning mode. The scanning function of the system improved motion blur scores about 30% compared with a non‐scanning LCD panel.
