Flexible OLED TV By LG

OLED TV

LG display has a prototype of 18-inch OLED TV screen that can be rolled up like a newspaper. This is found as the world’s first 18-inch rollable display. This paper-thin product was announced by the Korean giant. There are no details of the foldable yet released. But some experts suggest the technology could soon be used in smartphones and in-car display screens that curve around the vehicles’ interior.

This rollable screen will be featured alongside the 65-inch and 77-inch OLED TV panel. These two OLED panels feature a High Dynamic Range (HDR). The company claims its HDR option provides similar color accuracy to the monitors used to edit theatrical films. This foldable screen is as thin as 0.97 mm thick and weighs just 1.9 kg. It is lighter, thinner, and more flexible than standard LCD screens.

LG will also unveil a 55-inch OLED TV paper-thin display and a 65-inch extreme-curve concave/convex OLED displays. And it is set to introduce a 55-inch double-sided display which shows different video images on each side. A 139-inch Vertical Tiling OLED (VTO) display that is made of eight double-sided 65-inch OLED panels. They are connected together to form an S-shape pattern will also be on display. This VTO display shows different video images on each side.

This technology already exists in Apple watch and handsets like Samsung Galaxy Edge S6 and LG’s Flex phone. Most of the Samsung’s and LG’s high-end smartwatches and smartphones use the OLED displays. Samsung uses AMOLED and LG uses P-OLED. This new OLED plant being built in Korea is worth $900 million. It will make four times as many screens as the current-generation plant starting from 2017. This is all because of a larger ‘substrate’ sheet size.

The plastic-based displays are aimed at smaller next-gen devices that can benefit from the flexibility like automotive displays, cell phones, and wearables. There are other company’s products, like the Vivo X5, Oppo R7, and 2nd-gen Motorola Moto X that have OLED-based displays. Although, they create extra demand for the tech.

LG said it will eventually build another plant for larger, TV-sized displays with the same 6th-gen manufacturing system. LG has already shown off an ultrathin ‘wallpaper TV’ less than 1mm thickness. It is so light that it can be attached to the wall using just magnets using the technology.

LG said the flexible OLED TV is just a concept at the moment. This concept uses a magnetic mat that sits behind it on the wall. The TV can be then stuck to a wall using the pad. To remove the display screen from the wall, you need to peel the screen off the mat.

Unlike the LCD, these OLED TVs are much slimmer as the screen emits light itself without a backlight unit. Sang-Deog Yeo, the head of LG Display OLED business unit said, “OLED represents a groundbreaking technology, not only for the company but also for the industry.”

The company’s display strategy will center on OLED technology even though manufacturers have struggled to mass produce the more complex sets. Sang-Deog Yeo said, “It took a year and a half for us to raise the yield to this level (for OLEDs), while it had taken nearly 10 years to achieve the yield for LCDs.”

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

A professor at the University of Rochester in New York, Ching W. Tang said, “OLED displays will not become ubiquitous for another 5 to 10 years. They could outpace LCDs in total shipments.” He is also said the father of OLED according to CNET.

OLED is widely believed to be the next frontier. The technology adds an organic compound layer that not only allows for exceedingly thin screens but also 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 TV 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 used by companies like Samsung, LG, and Sony, costs quite high to produce the displays. Historically low yield or production of functional displays contribute to the high price of the display. More waste through production results in higher cost and that is then passed on to consumers. For instance, LG’s 65-inch 4K OLED TV costs $9,000.

The world’s biggest TV makers, Samsung and LG, are also turning to quantum dot technology for their next-generation TVs. This could still be years before OLED will be affordable on the market for the consumers.

The nascent technology involves incorporating a film of tiny light-emitting crystals into regular LCD. The manufacturing process is relatively straightforward. It offers excellent 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. Whereas an OLED TV could be 5 times more expensive.

LG recently launched a 65-inch ultra-high definition OLED TV for $11,350 in its home market of South Korea. And now, its turn for the flexible and foldable 18-inch OLED TV in this year later.
