LED Driver ICs for LCD Backlights LSI Series

Overview

ROHM LED driver ICs for LCD backlights were specifically designed to provide optimized viewing with low
power consumption. A special double dimming function adjusts the brightness based not only on ambient
conditions, but on image content as well for the ultimate in visibility.
ROHM's unique double dimming function adjusts the brightness based on image content and ambient
conditions, resulting in superior visibility with lower power consumption.
