Novel non‐isolation type high efficiency constant current DC‐DC converters and color control system with microcontroller for RGB‐LED backlight in LCD TV display have been developed and demonstrated. The efficiency of driver board is up to 94.4% and The maximum color deviation, Δu‘v’, from the target is 0.002.
