Firm believes organic light-emitting diode technology could be the display system in all products in the future.

Mounting a flat screen TV on the wall can be expensive and time consuming - and makes it very hard to redesign your room.

However, LG believes it has a solution.

The electronics giant has shown off an ultra-thin 'wallpaper TV' less than 1mm thick, and at 1.9kg so light it can be attached to the wall with magnets.

LG Display said the OLED TV is at the moment just a concept.


LG at a press event in Korea showed off the system, which uses a magnetic mat that sits behind it on the wall. The TV can then be stuck to a wall using the pad.

To remove the display from the wall, you peel the screen off the mat.

The firm hopes that OLED TVs are set to explode in popularity, with TVs that are much slimmer since the screen emits light itself without a backlight unit, unlike the liquid crystal display (LCD).

The head of LG Display's OLED business unit, Sang-Deog Yeo, said OLED represents a groundbreaking technology not only for the company, but also for the industry.

The unveiling was part of a broader announcement by LG Display to showcase its plans for the future.

The display is currently just a prototype. The company said its display strategy will centre on OLED technology -- even though manufacturers have struggled to mass produce the more complex sets.

LG vowed to ramp up OLED production from the third quarter of this year to a substantial level that can meet clients' demand, according to the Korea Times.

"We should be able to supply a satisfactory volume to our clients from July or August, which means we're hoping to buckle down production as well as promotion from the third quarter," Sang-Deog Yeo said.


"It has taken a year and half for us to raise the yield to this level [for OLEDs], while it'd taken nearly 10 years to achieve the yield for LCDs," he said.

LG Display will keep its focus on large screens, with a plan to introduce an OLED panel as big as 99 inches within this year, the executive said. The company has released its 55-inch, 66-inch and 77-inch OLED models earlier in the year.

The company also cited comments made at the press event by Ching Tang, a professor at the University of Rochester in New York and the father of OLED.

He said OLED displays will not become ubiquitous for another five to 10 years.

At that point, Tang said, they could outpace LCDs in total shipments. OLED is widely believed to be the next frontier for television.

The technology adds an organic compound layer that allows not only for exceedingly thin screens, but for those displays to be curved. The organic material also emits its own light, eliminating the need for a backlight. That allows for such thin screens and has made OLED a desirable choice not only for televisions, but for a wide range of wearables and other mobile products.


LG Display believes OLED could be the de facto display technology in all products in the future.

While some OLED screens have been used by companies like Samsung, LG and Sony, the costs are still quite high to produce the displays.

Part of that cost is due to a historically low yield, or production of displays that are actually functional. More waste means higher costs on the screens that do make it through production. Those costs are then passed on to consumers.

LG's 65-inch, 4K OLED TV, for instance, costs US$9000.

The world's biggest TV makers, Samsung Electronics and LG Electronics, are also turning to quantum dot technology for their next-generation TVs as it could still be years before OLED is affordable for the mass market.

One industry analyst estimated a 55-inch quantum dot TV could be priced 30 to 35 per cent more than a current LCD TV, while an OLED TV could be five times more expensive.


How it works

• The TV can be stuck to a wall thanks to a magnetic mat that sits behind it.
• To remove the display from the wall, you peel the screen off the mat.
• LG Display used high molecular substance-based polyimide film as the backplane of the flexible panel instead of conventional plastic to achieve the maximum curvature radius.
• The polyimide film also helped reduce the thickness of the panel to significantly improve its flexibility.
• As for the transparent OLED panel, it boasts 30 per cent transmittance, which was achieved by adopting the company's transparent pixel design technology.
