A Tokyo racetrack has become home to the world's largest large-screen video display. The screen is 218 feet wide (by 66 by 37). Judging from the picture, its ratio of width to height is way more than the standard 16:9 of DTV in general. Behind the display is Mitsubishi's Aurora Vision LED technology. Here LEDs are being used to produce the picture directly, though they're also creeping into consumer DLP displays as a substitute for the color wheel. The screen was installed in 35 pieces and cost $28 million.
