Daktronics will also hold the world's largest led screen record when they complete the Kansas City Royal's 100 feet high by 85 feet wide screen behind center field. Keep in mind that these screens have a 16mm led spacing and have to be assembled from many small led "cubes". Would love to play crysis on one of these screens since they can play HD signals.
Check out the dimensions on these huge displays in Yankee Stadium. The main two displays will have (64 feet diag)438.9 m2 of LEDs each! Outdoor screens have come a long way.
