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:
During SID Displayweek 2020, BOE demonstrated its 12.3" Full-HD rollable OLED prototype screen:
BOE now details that the display has a rolling radius of 5 mm, and it can roll 4 cycles. BOE says that device can survive over 100,000 bending cycles.
China-based OLED producer Visionox demonstrated some of its latest OLED technologies at SID Displayweek 2020.
In the video above you can see the company's latest foldable, wrap-around, rollable and flexible panels, in several configurations.
LGD opens a new OLED showroom, looks to collaborate with other industries to accelerate OLED adoption
LG Display announced that it is aiming to strike strategic cooperations with companies from industries such as the construction, furniture, and interior design, with an aim to find new application for next-generation OLED displays.
LGD opened a new OLED showroom at LG's Science Park in Magok which allows people to experience different OLED products - including transparent and mirror displays, wallpaper displays and "variable TVs" (not sure what is meant by that, perhaps it is a reference to LG's rollable OLED technology). LGD also released the video you see above showing several "virtual" OLED display demonstrations
LG's CEO, Kwon Bong-seok, announced that LG aims to be the first company to introduce a rollable OLED smartphone - as early as the beginning of 2021.
According to reports LG has already started working on prototype devices. Interestingly, according to the report the supplier of the rollable panel is BOE, and not LG Display.
IHS Markit says that the rollable OLED market is finally starting to emerge, and will grow quickly but unit shipments will remain slow in the foreseeable future. IHS sees 100,000 rollable OLED displays shipped in 2022, growing to 1.3 million by 2026. The CAGR from 2019 to 2026 will be 167%.
Rollable OLEDs will remain a niche- the share of rollable OLEDs from all flexible OLEDs will be 0.2% in 2026. Foldable OLEDs will be a much larger market - reaching 71.3 million units in 2025.
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.
