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:
TCL and Juhua Printing demonstrated a 31" FHD inkjet-printed rollable hybrid QD-OLED TV prototype. The display uses an IGZO (Oxide-TFT) backplane and TCL says that it has an aperture ratio of over 50%, brightness of 200 nits and a 90% DCI-P3 color gamut.
TCL's hybrid display technology (which TCL calls H-QLED) uses a blue OLED emitter coupled with red and green QD emitters. All three emitter materials are combined and printed using ink-jet printing technology.
Digital Trends published this nice video that shows LG's OLED booth at CES 2020, which shows LG's newest OLED TV technologies - including the 8K TVs, the Gallery OLED TVs and the rollable TV prototypes and products on display:
LG announced its 2020 OLED TV lineup - which includes 14 new OLED TVs, with some exciting new models and options.
Starting at the entry-level, LG will offer the OLEDBX and OLEDCX ranges, which will be what most people will opt for. The most interesting new model is the 48-inch OLED 48CX. It will be interesting to see LG's pricing for the 48-inch model, it was not announced yet.
LG Display announced that it will demonstrate several new OLED technologies at CES 2020 in Las Vegas next week (January 7-10).
First up, LG Display will show new applications for the aerospace market - including 55" transparent and flexible OLEDs used in airplane cabins. LG will also demonstrate a 65" bendable OLED TV, suitable for first-class cabins, that enable users to adjust the curvature of the TV to create a more immersive experience when required. It seems as if interest in OLEDs is increasing in the aerospace industry.
China-based OLED producer Visionox demonstrated a beautiful rollable OLED prototype:
We don't have any information about the display, but the demo looks great - complete with a notch in the OLED (not clear if that's just part of the image displayed, though).
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.
