On Tuesday, here on the Technology blog, we summed up a few of the TV-related highlights of the 2012 Consumer Electronics Show from LG, Vizio and Sony. But make no mistake, Sharp and Samsung made some news of their own.


As noted by my colleague Jon Healey and myself, 4K TVs have been a major trend at CES in Las Vegas this year. The promise of 4K TVs is a display that offers up to four times higher the resolution of today's highest resolution high-definition TVs, which currently top out at 1080p.

A bit confused by all the terms? No problem -- 1080p refers to TVs with a resolution of 1,920 x 1,080 pixels with the 1,080 counting the number of lines of resolution on the vertical side of the TV. The newer 4K standard refers to displays with about 4,000 lines of resolution counted on the horizontal side of a screen.

Sharp, however, took the resolution jump further than its rivals and introduced a prototype 8K TV this year, which it says will offer double the resolution of a 4K TV set, or a resolution of about 16 times higher than a 1080p TV. Sharp's 8K TV is currently planned for retail, but the prototype at CES did come in a whopping 85-inch screen size. The screen resolution of the Sharp prototype does fall short of an actual 8,000 mark, despite the name, with a 7,680 x 4,320 resolution display being used.

Huge TVs are something Sharp has been into for the last few years, choosing to concentrate on the higher-end of the TV market. This year it also showed off an 80-inch LCD TV, with LED backlighting, that will playback 3-D video (viewable with 3-D glasses of course). Sharp said its 80-inch was equal to about the size of nine 32-inch TVs, or about 266 smartphones laid out next to each other.

The TV maker also said it was committed to its LCD TV business and plans to introduce 17 new LCD TVs over the next 90 days.

But not all of those 17 new TVs will be big-screen heavyweight sets. As noted by my colleague David Sarno, Sharp also introduced its line of Aquos Freestyle TVs at CES this year. The Aquos Freestyle is a series of TVs that are built thin and light and can actually be picked up and moved around a home.

The idea is maybe you'd want to take the TV out in the back yard for a couple hours, or maybe into another room for a bit for a party or other good reason.

As reported by Sarno, "Sharp's Aquos Freestyle flat-screens get their signal wirelessly, and as the models demonstrated by parading them down the showroom runway, they are light enough to be carried around the home, whether to the balcony, the kitchen or the powder room."

Portable? Yes. Mobile? Not really. The Aquos Freestyle sets were shown off in 20-inch, 31.5-inch, 40-inch and 60-inch sizes.


Like Sharp, Korean electronics giant Samsung had some prototypes to show off at CES too, including a 55-inch TV that it described as "Super OLED."

OLED, or organic light emitting diodes, are more energy efficient, thinner and provide better black-levels when compared with standard current LEDs used in TVs today. OLED is also more expensive to produce than LED backlighting. And just about every TV maker throws out claims at CES that its display, which is also 3-D capable, provides the best picture -- Samsung's stance is no different with its Super OLED sets, promising in a statement that its prototype display offers "the ultimate in vividness, speed and thinness, with true-to-life picture quality, enhanced color accuracy and motion picture quality even in the fastest scenes."

Samsung also announced an update to its high-end Smart TV line, which runs apps such as Netflix on its TVs, that it says will allow users to control their sets with voice and motion control and facial-recognition technology.

"For example, users can turn the TV on or off, activate selected apps or search for content in the web browser simply by speaking in any of the 20 to 30 languages that are supported by the technology," Samsung said in a statement. "With a wave of their hand, they can browse and choose a link or content via the web browser."

A built-in camera in the top-of-the-line Smart TV sets "recognizes movement in the foreground and two unidirectional array microphones recognize voice at an incredibly accurate rate. Noise cancellation technology helps separate any background noise from the users commands."
