Abstract
Novel RGB-LED driving system for LED backlight in LCD display have been developed and demonstrated. The driving system consists of the non-isolation type high efficiency constant current DC-DC converter and the dynamic controller with microcontroller. The efficiency of driver is up to 94.4% and the maximum color deviation, Deltau´v´, from the target is 0.002
