Sony to sell ultra-HD '4K' TV set

NEW YORK (AP) -- High-definition TVs roughly quadrupled the resolution of the sets that came before them. Now, the industry is poised to do it again.

By December, U.S. stores will sell a TV set with four times the resolution of today's best HDTVs, Sony Corp. said Wednesday. The set will measure 84 inches on the diagonal, making the screen area four times as large as the common 42-inch set.

Executives said Sony will reveal the price of the set next week.

The exact resolution of the set is 3,840 by 2,160 pixels. It's known as "4K" because it has nearly 4,000 pixels on the horizontal edge. That compares with 1,920 by 1,080 pixels in "1080p" sets. More pixels allow TV makers to make bigger screens without compromising sharpness.

Sony makes digital projectors operating at 4K resolution for movie theaters.

The TV industry has been looking for a technology that will get consumers to upgrade their HDTV sets. Sales are slumping after an initial wave of upgrades from standard-definition sets, and 3-D sets attract only a small number of consumers.
