CES 2013: OLED TVs to finally go on sale LG's 84" OLED (organic light-emitting diode) set will be available in the US from March with a starting price of around $12,000. First promised three years ago, OLED sets provide lower running costs and higher contrast ratios to produce a new standard of picture, but have proved almost impossible to manufacture at scale. Samsung, which unveiled a similar model several years ago, has yet to announce a shipping date. Opening the Consumer Electronics Show in Las Vegas, LG joined Samsung in offering TVs that can respond to voice commands and gestures. It also renewed its emphasis on Google's TV platform. All the major TV brands are now focusing on Ultra High Defintion TV (UHDTV), which offers resolution four times greater than conventional HD. At least 10 companies are expected to launch UHDTVs, offering around 50 new models. Sharp, the most troubled of the screen manufacturers, reconfirmed its focus on bigger screens, starting at 60. The Consumer Electronics Association, the trade body representing manufacturers, said its research indicated that the average screen size in homes would climb beyond 40," as users replaced smaller TVs with larger flat-panel models. Sharp and others are also, however, trying to introduce the technology to smaller screen sizes, starting at 32. Even so, UHDTV is expected to remain a tough sell, with both programme makers and consumers. Sky and the BBC have both done some small scale trials but neither has confirmed plans to make shows in the new format. Analysts believe that high prices, coupled with consumers" "upgrade fatigue" could mean the technology's breakthrough remains years away, despite manufacturers" focus on the new standard.
