LG unveils an un-rollable OLED TV that’s just 1mm thick


LG Display, the division of LG that makes OLED display panels, has unveiled an incredibly thin television to prove its expertise.

At a press even in South Korea this week, LG showed off a ‘wallpaper’ proof of concept television. The 55-inch OLED (organic light emitting diode) screen weighs 1.9 kilos and is less than a millimetre thick. It also has a magnetic mat that sits behind it on the wall for attachment purposes. To remove the display, you simply peel the screen off the mat.

The new television was part of a showcase event held by LG Display to show off its vision of the future. According to its press release, the head of the company’s OLED unit, Sang-Deog Yeo, said “OLED represents a groundbreaking technology not only for the company, but also for the industry”.

While the HD era began years ago with technologies such as LCD and plasma,  it has since moved to LED technology, and OLED is widely believed to be the next battle front.

The technology uses an organic compound layer that allows for incredibly thin screens, and for them to be curved. The material also emits light, removing the need to have a backlight. That allows the super thin screens and makes OLED a great choice not only for televisions, but a wide range of mobile devices and wearables. LG says OLED could be the standard display technology in all products in future.

LG Roll Up TV

OLED screens have already been used by companies like Samsung, LG and Sony, but they are expensive to produce. That’s partly due to low yield, in other words displays that are functional. More waste means that the costs are higher for screens that make it through to production, with the costs eventually being met by consumers. For example, LG’s 65-inch 4K OLED TV costs more than $9,000.

This week, LG said it has made a lot of progress developing OLEDs. It said it’s the first to mass-produce large-screen OLED displays for televisions and that its yield has now hit 80%, pretty strong but still much lower than for LCDs.

The issues with yield and price mean the wallpaper-like screens may not make it to stores at reasonable prices any time soon.

LG said it expects to sell 600,000 OLED television panels this year and 1.5 million next year, and also cited comments made by Ching W. Tang, professor at the University of Rochester in New York and the ‘father of OLED’.

He says that OLED displays will not become mainstream for another 5 to 10 years. By then though, Tang said they may even outpace LCDs in units shipped.
