LG shows off impossibly thin television

Big-screen televisions have been getting thinner and thinner, while they get bigger and bigger. 

Now, LG has come up with what some are calling an impossibly thin television.

Under the division LG Display, the electronics company showed off a "wallpaper" concept television recently.

It has been making the rounds at tech shows around the world, including back in May in New York City.

It is less than a millimeter thick, weighs just over 4 pounds and is made of OLEDs (organic light-emitting diodes) CNET reported.

It sticks to the wall thanks to a magnetic mat. To move the TV, you just peel it off the mat. 

OLED is what allows the screens to be so thin. It creates its own light, so no backlight is needed. OLED is also being used for wearables and other mobile products, CNET reported.

Another smaller model was introduced in July. It is so flexible that it can be rolled up. A third is transparent. It can be hidden on home and office walls, CNET reported.

But don't get your heart set on the new thin television, yet. It could be at least another five to 10 years until they are readily available, due to the fact that companies are having difficulty making units that are functional. LG said it has hit an 80 percent yield, meaning that 20 percent of manufactured televisions don't work. 

LG Displays said it hopes to sell 600,000 OLED TVs this year and 1.5 million next year in a more traditional form.

Sony and Samsung have started producing OLED screens that look more like a traditional flat screen television. But the technology comes with a high price. LG's 65-inch, 4k OLED TV costs about $9,000, CNET reported.

Eventually though, once companies get a higher yield, with a lower cost, experts say the new OLED screens could eventually outpace LCDs in the future.

LG is not the only company working on flexible displays. Samsung, Nokia and Apple have been developing flexible smartphone and tablet screens, CNET reported
