The CCFL to LED conversion power supply reference design replaces the backlight CCFLs with strings of light-emitting diodes (LEDs). LEDs operate at low voltages of 3.5V to 4.5V each and are extremely durable. They produce a brighter light whose spectral content can be more easily custom-tailored to the needs of the backlight. Their brightness can be easily controlled to compensate for changes in ambient light. Also in contrast to the glass-tubed CCFLs, the physically small LEDs can be mounted on flexible strips, allowing a display to be more tolerant of and resistant to sudden shocks.
