Powering LED-backlit LCDs using DC-DC topology (Part 1)
The electrical configuration of these LEDs is also critical because some configurations can lead to impractical, expensive, or inefficient driver designs. With the use of medium- to high-power LEDs, the driver electronics are more simplified, but the optics can become more challenging, requiring more elaborate schemes to turn a small number of point sources into a single, uniform backlight.
In order to properly drive the wide variety of LED backlit panels available on the market now, electrical design engineers will need to successfully implement one of the many LED driving topologies available.
