It's far from the biggest LED display we've seen, but Panasonic's new Astrovision/AZ-LE12F series display is certainly impressive enough in its own right, thanks in no small part to its blinding 5,000 cd/m2 brightness rating. At over 13 feet across and nearly ten feet high, it's also hard to go unnoticed, which appears to be the intention as the first such display has now been installed in the new "Qiball" building in Chiba City, Japan. Passers-by should also be able to get a good look at the display thanks to its wide 145 degree horizontal viewing angle and 80 degree vertical viewing angle, with the display also promising "excellent RGB blending" from its 3-in-1 LEDs. Sadly, there's no word on a home version just yet, so it looks like you'll have to make do with some of the slightly smaller options currently at your disposal.
