LAS VEGAS -- In 2014, Sharp debuted its Quattron+ technology, which was designed to bring 4K-like pictures to a 1080p screen, but it was held back by the limitations of HD pixels . Sharp is now taking this four-color spinoff to its (il)logical extreme by installing it inside a 80-inch 4K screen.

Calling this new beast "Beyond 4K Ultra HD TV," Sharp splits the red, green, blue and yellow subpixels on the fly in order to generate up to 66 million onscreen pixels, As this screen likely won't be able to display 8K or whatever standard comes next, the answer to "Why are they doing this?" seems to be "Because they can."

But the reason to consider this screen isn't for the whizz-bangery of the pixel-splitting tech but for the other, more useful picture-enhancing features it offers.

The display will use the " Quantum Dots-like" SPECTROS technology to display even more colors than before with Sharp claiming it will display more than more than 100 percent of the Digital Cinema Initiative (DCI) Color Space used in theaters, though not yet in the home.

In addition, the TV will include High Dynamic Range technology -- though no word yet if it is Dolby HDR -- and a full-array LED with local dimming for what promises to be excellent contrast for an LED screen

How much would you expect to pay? Well, don't answer yet because sadly you'll need to wait to the end of 2015 before you can get one. Watch this space for more info on Sharp's most feature-packed television yet.
