Info about LED technology

[behranghm]

Hi everyone, I was wondering what these huge LED boards in open environments on which even movies could be displayed are? What are they exactly called in electronic terminology? How do they work? Are they designed to be connected directly to the output of a graphic card? Can anybody give me a hint about where I can get started? Perhaps a link to a website? Or maybe some circuit schematics?
Thank you all.
