Rollable OLED displays are exciting - as these displays can enable new device form factors - such as TVs that roll up into a small cylinder or a tablet-sized device that can roll-up into a pen.
Rollable OLED TVs
In early 2019, LG launched the world's first rollable OLED device - a TV that rolls into its base. The 65" Signature OLED TV R has three viewing options - full view, line view and zero view. This is a radical new TV form factor, which will be probably be highly expensive when it starts shipping during 2019 (we still do not know the exact release date and price). The TV offers the highest image quality - enabled by OLED technology.
Rollable mobile devices
While LG is leading the race to rollable OLED TVs, many display makers are developing smaller rollable OLED displays for mobile devices. Back in 2016, for example Samsung Display demonstrated a beautiful rollable OLED, a 5.7" display that featured a Full-HD resolution (386 PPI) and a curvature radius of 10 mm. The whole display is 0.3 mm thick and weighs 5 grams. We do not know yet when SDC plans to commercialize such a display (the company is currently focused on developing its foldable OLEDs).
The latest rollable OLED news:
Sharp announced that it has developed, in collaboration with NHK, a 30" rollable 4K OLED panel on an IGZO backplane. This is a direct emission OLED, which sharp says is the world's largest ever produced (LG's OLEDs all use color filters).
Sharp's OLED panel is deposited on a thin-film substrate, and has a thickness of 0.5 mm. The display uses NHK's signal processing and panel driving technologies to "improve the brightness uniformity and video clarity".
In early 2019 LG Electronics announced the world's first rollable OLED TV, the 65" Signature OLED TV R. The company later announced that it will ship the TV in the second half of 2019, but now LG is delaying the launch of its signature rollable OLED TV.
LG says that the OLED TV R will ship in Korea in "2019 or 2020", but that consumers elsewhere will have to wait longer - which probably means it does not have any plans to release it before 2021. According to TechRadar, the main reason is that LG is highly expensive and LG fears that it will be difficult to find a market outside of Korea for such a premium TV.
China-based BOE Display demonstrated many OLED displays at SID 2019, including new flexible, foldable, rollable and automotive AMOLED displays. Here's a video showing the company's complete SID lineup:
China-based BOE Display has a very ambitious OLED project, and the company unveiled new flexible and automotive OLEDs at SID 2019.
BOE demonstrated several new automotive OLED technologies including a 12.3" flexible OLED display for the main instrument panel which employs a new pixel compensation circuit technology apparently developed by BOE, which can improve the brightness uniformity of the display.
In early 2019 LG Electronics announced the world's first rollable OLED TV, the 65" Signature OLED TV R and the 88" 8K Z9 OLED TV. Today LGE announced that it plans to start shipping both TVs in the second half of 2019, in Korea. LG did not disclose the price of these two high-end TVs.
The rollable and 88" OLED TVs will be highly expensive - these are high-end premium products. LG Electronics did however say that as it shipped over 4 million OLED TVs since the first one shipped in March 2013, OLED TVs are now "crossing the chasm" and are starting to be adopted by the mainstream market and not only early adopters.
In January 2018 LG Display unveiled its largest OLED TV panel yet - a 88" 8K (7680x4320) display. In early 2019 LG Electronics announced that it will adopt this panel in its upcoming OLED Z9 88" OLED TV. Yesterday in Shanghai at the Appliance & Electronics World Expo 2019 (AWE2019) Skyworth demonstrates its own 88" 8K OLED TV.
We do not have any details on this TV, and whether it is just a prototype or a product that Skyworth aims to launch soon. In any case it turns out that Skyworth already demonstrated this TV at CES 2019, but we failed to report on that. In addition to the large OLED, Skyworth also demonstrated a new OLED TV design which they call waterfall OLED - look at the image below to understand why. It is not clear but it is likely that this is a prototype rollable OLED TV.
UBI Research estimates that the OLED market will reach $32.2 billion in revenues, up from 13.8% from 2018. UBI says the the growth will come from new applications - including foldable smartphone displays, 8K OLED TVs and rollable OLED TVs. Increased yields by Chinese AMOLED makers will also contribute to the growth.
AMOLED revenues in Q4 2018 reached $7.9 billion (down 3.7% from Q3 2018 and 10.4% from Q4 2017). In the whole of 2018, revenues reached $28.3 billion, up 7.1% from 2017 ($26.4 billion). UBI sees the oversupply in the flexible OLED market to continue as high prices prevent adoption in mid-end smartphones.
At CES 2019, LG Electronics announced its first rollable TV (and the world's first rollable OLED device), the 65" Signature OLED TV R. Market analysts from IHS estimate that producing each 65" rollable OLED TV will cost over $3,000 - more than three times the cost of production of LG's regular 65" OLED TV panels.
LG's new TV can roll up into its base, and has three viewing options - full view, line view and zero view. In Line View, there are six different modes, in which the TV can show the weather, the time, a home dashboard and more. Like the rest of LG's 2019 OLED range, the OLED TV R is based on the company's 2nd-gen Alpha 9 intelligent processor the enables LG's ThinQ AI to offer new display algorithms and Amazon's Alexa and Google's Assistant.
As was reported last month, LG Electronics announced its first rollable TV (and the world's first rollable OLED device), the 65" Signature OLED TV R.

The TV also features HDMI 2.1, high frame rate (HFR) support, enhanced audio return channel (eARC), variable refresh rate (VRR) and automatic low latency mode (ALLM). LG's flagship OLED also feature Dolby Atmos for immersive entertainment.
LG Display has already demonstrated rollable OLED TVs (and according to reports it aims to release the first such TV to the market in 2019) - but Samsung has been left behind as its current LCD-QLED TV technology choice does not enable rollable TVs.
LGD's prototype rollable TV (unveiled in 2018) rolls vertically, inside a single case at the bottom. According to a new patent recently awarded in the US (USPTO #10,162,387) Samsung has a different design in mind - a TV that rolls horizontally, as you can see in the image above.
