It provides the dimming ballast control and the contrast control for the LCD display. By utilizing differential drive the ML4876 can deliver the same light output with significantly less input power compared to existing single ended drive schemes. Improvements as high as 30% can be realized when using low power lamps and advanced LCD screen housings.
