LAS VEGAS -- TV makers showing off their new wares at a huge trade fair will seek to dazzle consumers with bigger, bolder displays, and smarter technologies for consumers who want television to be a "multiscreen" experience.

Companies like Samsung (IW 1000/15), Sony (IW 1000/33), LG (IW 1000/87), Sharp (IW 1000/115) and Panasonic (IW 1000/30) showing at the International CES in Las Vegas this week are making a new push for so-called "ultra HD" high definition of 4K, which can provide stunning, lifelike images at a steep price.

Size is on the rise, with many consumers looking at screen measuring 60 inches, especially in the United States, according to the industry.

"For U.S. consumers, bigger is absolutely better," said John Herrington of the U.S. division of Japan's Sharp, one of biggest sellers of jumbo TVs in the American market.

Sharp is selling TVs with displays up to 84 inchesusing its high-definition display technology called IGZO, using indium gallium zinc oxide.

Samsung meanwhile unveiled a new television that lets two people watch two different shows at the same time. The F9500 television is the first in the world to offer this feature, dubbed "multi-view," using screen technology called "organic light-emitting diode" or OLED.

Viewers must wear special 3D glasses, which come with personal speakers built in to deliver the audio, in stereo, directly to them.
