Abstract
This paper presents a digital LCD(Liquid Crystal Display) backlight inverter control using an 8-bit microcontroller. The backlight uses cold cathode fluorescent lamps(CCFLs) that have the negative resistance characteristics, so it requires the ballast function. For this, the proposed LCD backlight inverter uses an 8-bit microcontroller, ATmega128. Therefore, the controller circuit is simplified and cost-minimized. It shows through the experimental results that the proposed inverter has good performance for the LCD backlight inverter.
