Foldable OLED displays are exciting - as these displays will enable new device form factors - such as phones that open into tablets, smart bands that open into smartphones and more. In 2019 the first such products are finally arriving on the market!

The first foldable smartphones

In 2013, Samsung kicked off the foldable OLED market, sort of, when it announced its YOUM flexible OLED brand, showing off several flexible OLED prototypes - including a foldable phone/tablet. Samsung never used the YOUM brand name again, but Samsung has continued to develop its foldable OLED technology.

In 2015 we started hearing the first reports of Samsung's Project Valley. Samsung hoped to release its first foldable device in 2016, but the company faced many challenges including problems with the substrate and the software and user interface. In 2019 Samsung finally introduced the first device, the Galaxy Fold - which was launched prematurely, though, which compelled Samsung to halt production, fixed some design issues - and hopefully the company will finally launch the device again in September 2019.

Samsung's first foldable device uses two screens - a large 7.3" 1532x2152 (361 PPI) foldable AMOLED that folds inside, and a smaller 4.5" 840x1960 AMOLED that is used when the phone is closed. Samsung brands the display as the Samsung Infinity Flex Display. The Galaxy Fold is relatively thick and bulky - and is expensive (around $2,000).



Other companies are also developing such devices - Royole is already shipping a "developer" edition of the FlexPai phone/tablet, with its 7.8" 1920x1440 (308 PPI) AMOLED display that fold outwards.

In February 2019 Huawei launched its first foldable smartphone, the Mate X with a 8" 2200x2480 foldable AMOLED display that folds outwards. Huawei said it will launch the Mate X by the end of June, but now the company says it is now planning to release it in September.Huawei Mate X folding photo

In September 2019 Nubia unveiled the Alpha - smartband that turns into a smartphone - with a foldable OLED display. Nubia started shipping this device in China in early 2019. Xiaomi has also teased a beautiful tri-folded OLED smartphone.

In May 2019 Lenovo demonstrated a prototype 13.3" foldable OLED ThinkPad laptop - with LGD providing the display. Lenovo said that it developed this device for over three years, and hopes to launched a commercial one in 2020.

Foldable OLED developers

Samsung Display is not the only display maker to develop foldable OLED technologies. China's BOE Display seems to be another leading foldable OLED developer. In May 2018, BOE demonstrated several impressive new technologies, including a 6.2" 1440x3008 foldable (1R) OLED display with a touch layer and a foldable 7.56" 2048x1535 OLED. According to reports, BOE is working with three companies, including Huawei, with four different devices under development. BOE is likely to be the display supplier for Huawei's Mate X.

In September 2018, Chinese smartphone maker Nubia unveiled its first foldable device, the Nubia Alpha. The Alpha uses a tall and slim foldable OLED and turns from a slim phone to a wearable smartwatch. The device is now shipping in China. The producer of the Nubia Alpha's display is China-based Visionox. Visionox is also supplying the OLEDs to Xiaomi's prototypes.

SCREEN FT announces a new coater for the forming of color filter films for foldable/rollable OLED production

SCREEN Finetech Solutions developed a new coater (SK-F1500H) for color filter film forming with anti-reflective properties. These color filters are intended to be used in flexible (foldable/rollable) OLED devices. The company says the new coater is able to achieve outstanding efficiency by executing the entire process in a single integrated line (6-Gen / 2 substrate).

SCREEN Finetech Solutions SK-F1500H for rollable/foldable OLED color-filter deposition

SCREEN FT explains that in current rollable and foldable OLEDs, the multi-film structure is a weak point that is one of the reasons these display get wrinkled and damaged when bent. One of the problems is in the multi-layered circular polarizers. Color filter films can replace the polarizers, reduce the number of layers, and enable high transmittance and higher energy efficiency.

UBI: the COVID pandemic decreased demand for OLED smartphone displays, while demand for wearable displays have risen sharply

UBI Research estimates that OLED shipments in the first half of 2020 were 231 million units ($13.2 billion), pretty much the same as in the first half of 2019 (230 million, $13.8 billion). UBI estimates that the COVID-19 pandemic decreased demand for OLED displays.

Online review shows that the Galaxy Z Fold 2 is more durable than the original Fold, but not by much

When Samsung launched its original foldable smartphone, it used a polyimide-based cover, and the screen was fragile and not very durable. Later in 2020 Samsung Display launched its ultra-thin-glass (UTG) cover (produced by Schott and processed by Dowoo Insys) which the company said is more durable the the Polyimide.

Samsung Electronics continued to adopt the new foldable UTG cover and used it in its Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) smartphone. But the question remains - just how more durable is the UTG-protected OLED?

Lenovo starts accepting pre-orders for the foldable ThinkPad Fold

In early 2020 Lenovo announced the foldable ThinkPad Fold laptop, and the company is now starting to accept pre-orders for this innovative device which starts at $2,499. Lenovo ThinkPad X1 Fold photo

The ThinkPad X1 Fold features a 13.3" 2048x1536 foldable OLED display that is produced by LG Display. LG's collaboration with Lenovo was announced in May 2019 - but interestingly in November 2019 BOE also said that it is collaborating with Lenovo and that it supplied Lenovo with the 13.3" foldable OLED it used in the prototype ThinkPad X1 foldable laptop it demonstrated in May 2019.

DSCC: the foldable/rollable smartphone market will grow to $105 billion by 2025

DSCC says that the foldable/rollable smartphone market will be one of the fastest growing consumer electronics market - and sales of such smartphones will grow to $105 billion by 2025, in a CAGR of 80%.

The display area used in such devices will grow a 93% CAGR, to reach 1.2 million square meters by 2025. In terms of units, 74.4 million rollable/foldable smartphones will ship in 2025.

Samsung Display announces a 1.4R foldable OLED display

Samsung Display announced that it has commercialized a new foldable OLED display that is the first to achieve a curvature radius of 1.4R mm. This display will be adopted in Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) with an Ultra-Thin Glass (UTG) cover glass.

Samsung says that in order to minimize the folding stress that is increased in such a small folding radius, the company has optimized a series of technologies related to the material of the display, the panel design and the module assembly, so that the multi-layered structure will function like a cushion when the panel is folded.

Samsung Electronics collaborates with Corning on Ultra Thin Glass technology for foldable OLEDs

Samsung started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. In the Galaxy Z Flip, Samsung used a UTG cover produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass for Samsung Display.

In April 2020 it was reported that Samsung Electronics wants to develop its own UTG cover technology, as as it feels that Samsung Display's UTG is still not robust enough and the company also wants to increase production yields and reduce costs. Now there are new reports from Korea that say that Samsung Electronics is collaborating with Corning in this new UTG project.
