Foldable OLEDs: introduction and market status

Huawei officially announces the world's first tri-folding OLED smartphone, the Mate XT. The phone and its specifications will be unveiled on September 10, and will ship on September 20.

Huawei allows people to reserve their Mate XT phone, and already over 1.25 million people reserved it. 

Omdia says that Color-Filter on Encapsulation (COE) will grow to be the dominant technology in foldable OLED smartphone panels, and will replace the currently-used circular polarizers. COE adoption will grow at a 33% CAGR between 2024-2030, and by 2030 almost 90% of foldable smartphones will use COE technology, and almost 20% of all smartphone OLED panels.

The adoption of COE in OLEDs increases the panel effective brightness, which means that the display consumes less power compared to a polarizer OLED (same brightness) and also lasts longer. The color gamut is also improved. On the other hand, COE OLEDs suffer from higher reflectivity compared to polarizer OLEDs. 

Recently, BOE, Tianma, TCL, EDO and Visionox all posted their financial results for Q2 2024, and all were rather positive. Samsung Display and LG Display also posted increased earnings for the quarter.

So we start with BOE, that posted revenues of 93.4 billion yuan (13.17 billion USD) for the first half of 2024, an increase of 16.47% over H1 2023. Its net profit increased 210% compared to last year (2.285 billion Yuan, or $320 million USD). BOE enjoyed increased LCD sales and optimized production, and also noted high demand for high-end foldable OLED displays.

China-based smartphone maker Tecno has unveiled a new concept device, called the Phantom Ultimate 2, that sports a tri-folding OLED display.

The device is actually a working prototype, that when fully opened has a 10-inch 1620x2880 LTPO AMOLED display. When fully closed, the display is 6.48" in size. The company says it has developed a unique hinge design that enables the whole phone to be only 11 mm thick when fully closed. Tecno tested the device and the hinge and it lasts for over 300,000 folding cycles.

UBI Research says that shipments of foldable OLED smartphone panels more than doubled in Q2 2024 (compared to the first quarter), reaching 9.94 million units. Foldable OLED smartphone panels accounted for 5.2% of the total OLED smartphone display market.

UBI expects foldable OLED panel shipments to continue growing in the second half of 2024, and sees total 2024 shipments exceeding 40 million. By 2028, the company expects foldable OLED panels to reach an almost 10% out of the entire OLED smartphone market.

DSCC says that shipments of foldable OLED panels reached a record high in the second quarter of 2024 at 9.8 million units - 126% higher than Q2 2023 (and 151% higher than the previous quarter). DSCC believes this will be the peak quarter in 2024, as the demand was fueled by the launch of Samsung's latest foldables, the Galaxy Z Flip 6 and Z Fold 6.

Samsung holds an almost 50% market share in foldable smartphone panels orders, followed by Huawei at 29%. Timing is relevant, as high demand follows new model shipping dates. DSCC estimates that clamshell devices have a 63% market share out of the total foldable smartphone market, with the rest taken up by in-folding devices.

Google announced five new devices, all powered by AMOLED displays. We'll start with the Pixel 9 smartphone series, with the plain Pixel 9 offers a 6.3" 120Hz 2,700 nits (peak) 1080x2424 AMOLED display, a Google Tensor G4 chipset, 12GB of RAM and 256 GB of storage. The Pixel 9 Pro offers a 6.3" 3,000 nits (peak) 120Hz 1280x2856 LTPO AMOLED, and up to 16 GB of RAM and 1 TB of storage. The Pixel 9 Pro XL offers a similar but larger display - 6.8" 1344x2992 LTPO AMOLED.

Google's Pixel 9 Pro Fold smartphone is based on a 8" 120Hz 2,700 nits (peak) 2076x2152 foldable LTPO AMOLED display, and an external 6.3" 120Hz 1080x2424 AMOLED. The Pixel 9 Pro Fold is powered by a Google Tensor G4 chipset, and offers up to 16GB of RAM and up to 512GB of storage.

Back in February we posted about rumors that suggest Huawei is planning to release the industry's first smartphone that sports a tri-foldable OLED display. When fully open, the device will sport a 10" display, which means it will double as a full tablet and a smartphone.

Now we have seen a photo of Huawei's Chairman that uses such a smartphone on a flight. This could mean that Huawei is getting ready to officially launch such a phone.

Xiaomi announced four new devices, all with high-end AMOLED displays. First up we have the Mix Fold 4, a foldable smartphone that has a 7.98" 120Hz 3000 nits 2224x2488 foldable LTPO AMOLED display, and a second 6.56" 120Hz 3000 nits 1080x2520 LTPO external AMOLED display.

Samsung announced today four new devices - two foldable smartphones, and two smartwatches, all with AMOLED displays. All of these devices will ship on July 24.

First we have the latest clamshell smartphone, the Galaxy Z Flip6 - that has a foldable 6.7" 120Hz 2,600 nits 1080x2640 LTPO AMOLED display. It also has a 3.4" 720x748 Super AMOLED cover display.
