Description:
The legacy of the LG rollable OLED TV may be in the smaller, more portable devices it inspires rather than simply a cheaper version of the same technology.

FULL STORY ======================================================================

The LG rollable OLED TV has, since its launch, been an exciting mess of contradictions. The primary one being that, while its innovative unfurling mechanism makes it a great space-saving measure, the high price tag means its likely only to feature in the large homes of the wealthy.

Retailing for $99,999 / 99,999 in the US and UK, the rollable OLED is little more than a proof of concept to be enjoyed by a small handful of technology enthusiasts with the added convenience of its rolling mechanism having to be weighed up with the exponential cost compared to an LG C1 or LG G1 OLED , either of which could be bought 50 times over for the same amount of cash. Thats despite both featuring effectively the same panels and processors as their rollable counterpart.

A rollable OLED TV will only really enter the mainstream when costs reduce sufficiently though it may be the models legacy is in the smaller, more portable devices it inspires rather than simply a cheaper version of the same technology.

Thats what were told by Jacky Qui, VP and Co-Founder of OTI Lumionics an innovator in next-gen OLED display tech who spoke exclusively to TechRadar about where the LG rollable OLED TV could go next. What does LG have to
prove?

Qui tells us that The high cost for the rollable OLED TV is due to reduced yield for the new process required to make the rollable TV, and while production costs should gradually decrease, and the RRP drop for any hypothetical second iteration, it is unlikely that you can see a 10x price reduction from $100,000 a unit to $10,000 a unit.

The great complexity of the production process is a huge factor here, given the challenge of ensuring an ultra-thin 55-inch TV panel can be handled without damages an issue that plagued early OLED TV production and led various big TV brands to ditch the technology altogether, even if some came back into the fold after LGs success in the area. That problem is only exacerbated by foldable technologies, as the screen needs to be continually manipulated in and out of a curled up shape without issue. (Image credit: LG)

The main difficulty, says Qui, is in handling of this glass without any
damage throughout the whole process from evaporation in a production line thats longer than a football field, while also making sure its perfectly
flat; packaging the piece of glass to prevent moisture from getting in (to a spec equivalent to that only one drop of water can get in over the size of a football field); putting all of the electronics on the panel to make the module; and finally packaging the panel into the rollable form and undergo rigorous testing to ensure mechanical and performance stability over many rolling cycles is not trivial.

So for anyone hoping to get the OLED R as their next television upgrade, its not very likely to happen in the next few years. Qui also makes the point
that LG Display currently has a monopoly on OLED TV and demand remains very high, so theres very little motivation for them to turn their rollable OLED into a mass-market money-spinner, rather than the aspirational technology demonstrator it is now. Merrily we roll along

The main draw of the rollable OLED, or LG Signature Series OLED R, is how the screen can be rolled up into its base station either hiding the screen entirely or showing a portion of it as a rectangular smart display.

As Qui says, the current pilot product could start to enter the mainstream market if it drops to the $10,000-$20,000 bracket, though its unlikely to happen in the near future. But while a rollable OLED 2.0 might still feature an inaccessible price tag, the real legacy of this technology could be in quite a different form factor one that ditches a glass panel for plastic
OLED tech that can be more easily manipulated, and more easily produced at scale. (Image credit: LG)

Based on our conversations with people in the industry that are knowledgeable about the LG rollable OLED TV, says Qui, a key benefit everyone is touting is the fact that TV can be portable and moved from one room to another. Thus,
the key innovation to come would be if the rollable OLED TV can utilize plastic OLED technology to reduce weight of the panel, reduce bending/rolling radius and thus reduce the mechanical component and enclosure weight requirements, allowing for a more resilient (higher yield) and portable device.

While we have no predictions for 2.0 model at this time, we are incredibly excited about the prospect of a smaller panel, and more resilient rollable OLED TV as the path forward for cost reduction for the rollable OLED TV
genre, and we believe a positive market reaction to the current offering
would be very helpful to push the technology forward.

A smaller, lighter television with a more portable base station say, without the 100W 4.2 channel Atmos speaker system on the current rollable OLED TV could be far more easily transported between rooms, stuck in a cupboard, even packed into a car boot to take on holiday to a hotel or B&B, if not just over to a friends house for a cozy movie night. If the Nintendo Switch showed
there was a market for home devices that can also be taken on the go, why couldnt an LG TV do the same thing?

A cheaper-to-make TV, produced at a larger scale, could also get us close to that $10,000-$20,000 price point not a budget device by any means, but one that could start finding itself in far more homes and retail spaces.

Its obviously too early to give any speculation too much weight: LGs rollable OLED prototype took over two years to go from its first trade show appearance to actually releasing in South Korea, and another year before we saw it in Western markets. Any meaningful iteration is likely a long while off, especially one that disrupts the television industry in the way that a truly portable OLED TV display could.

But for those balking at the high price of LGs current rollable offering, there may be hope yet for a version of this screen that truly realizes the potential of rollable technology. Check out the best OLED TVs
