Set your eyes to stun. Panasonic Japan just raised the game in the "mine is bigger than yours" battle by taking the wraps off its huge 145-inch 8k television, thus outdoing Sharp's 85-inch 8k set by a healthy margin.
The mammoth plasma set, made in partnership with Japan's public broadcaster NHK, has a sizable 7680-by-4320-pixel resolution and claims to be the world's first self-luminous display (that is, it doesn't need a backlight). By comparison, current HDTVs typically max out at 1920-by-1080-pixel resolution. Panasonic's also claims that its new TV is flicker-free, something difficult to achieve on a display of this size.
The "Super Hi-Vision" display, a technology also known as ultra high definition television, is currently only a prototype, with 8k technology still several years away from being ready for consumers. The long wait for TV sets of this magnatude is proabably a good thing, as it will give you plenty of time to save for a bigger house--something you're no doubt going to need in order to accomodate larger televisions like this.
The huge 145-inch TV will be shown in action next month at NHK's laboratories, and will then visit the US in June. If you're going, you may want to take a pair of shades.
