We've seen big HDTVs before, claiming to be world's largest, but now Mitsubishi has topped them all, building a high-definition video screen at a horseracing track in Tokyo that's 218 feet wide and 37 feet tall, taking up 8000 square feet—that's nearly a fifth of an acre. The screen, delivered in 35 pieces and assembled at the Tokyo racecourse, uses Mitsubishi's Aurora Vision LED technology.
The previous holder of the world's largest HDTV record is an LED screen which is only 137 feet across, located at Dolphin Stadium in Miami. Want a screen like this current world's-largest? Start saving up, because it's $28 million.
