LED Backlight

The LED backlight has two basic configurations;Array & edge lit.In both types the LEDs are the light source that are focused into a diffuser that distributes the light evenly behind the viewing area.In Array lit configuration there are many LEDs mounted uniformly behind the display,it offers more uniform and brighter lighting & consumes more power.In Edge lit configuration,the LEDs are mounted to on side(typically the top)focused edge on into the diffuser,it offers a thinner package and consumes less power.
