http://www.epicphysics.com/practical-... A brief video showing how an LED works and how super bright leds work. Super bright leds work on some fairly straightforward semiconductor physics. An leds brightness can be increased by increasing the current supplied, however you must not apply too much current as you can damage the sophisticated mechanism where electrons and holes transfer from one semiconductor to the other. If you apply too much current the LED will suddenly give off a flash of bright light and then fail. Super bright led displays are simply arrangement of hundreds of super bright leds.
