The LG 'wallpaper TV' so thin and light you can hang it on the wall using MAGNETS

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 ultrathin 'wallpaper TV' less than 1mm thick, and at 1.9kg (4lbs) is so light it can be attached to the wall using just magnets. At a press event in Korea on Tuesday, it showed off the system. It 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 OLED TVs are set to explode in popularity. They mean 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.'

LG has revealed a working roll-up TV that is also transparent when not in use. The Ultra HD screen uses a special film instead of plastic as backing to allow screen to be rolled into a tight tube for transport

The unveiling was part of a broader announcement by LG Display to showcase its plans for the future. The company said its display strategy will center 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 told reporters.

Thanks to a magnetic mat that sits behind it on the wall, the TV can be stuck to a wall. 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 percent transmittance, which was achieved by adopting the company’s transparent pixel design technology. 

This latest prototype is the successor to a similar 55-inch set unveiled by LG in 2012 that was 4mm thick (pictured). TVs using OLEDs - organic light-emitting diodes - offer images with enhanced clarity, deeper colour saturation and sharper contrast than standard liquid crystal display (LCD) TVs

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 W. Tang, a professor at the University of Rochester in New York and 'the father of OLED' according to CNET. 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. 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 N1.8m ($9,000 or £5,800). The world's biggest TV makers, Samsung Electronics Co Ltd and LG Electronics Inc , 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.
The nascent technology involves incorporating a film of tiny light-emitting crystals into regular liquid crystal displays (LCD).

The manufacturing process is relatively straightforward and offers improved picture quality at much cheaper cost than using organic light-emitting diodes (OLED). The resulting lower prices could help the technology catch on far quicker. One industry analyst estimated a 55-inch quantum dot TV could be priced 30 to 35 percent more than a current LCD TV, while an OLED TV could be 5 times more expensive. LG recently launched a 65-inch ultra-high definition OLED TV for 12 million won N2.2m ($11,350) in its home market of South Korea.

OLED stands for organic light-emitting diode. Its panels are made from organic materials that emit light when electricity is applied to them. As a result, OLED panels don't use a backlight meaning they are thinner than LCD displays. OLEDs additionally have bright colours, brilliant contrasts and a wide-viewing angle.
