Flexible OLEDs: introduction and market status
OLED is an emerging display technology that enables beautiful and efficient displays and lighting panels. OLEDs are already being used in smartphones, laptops, wearables, tablets and TVs, and many of OLEDs are flexible ones.
A flexible OLED is based on a flexible substrate (usually polyimide). The first generation of OLEDs produced on these were not really flexible from the user perspective. The device maker bends the displays, or curves it - but the final user is not able to actually bend the device. These first-gen flexible OLEDs are adopted many premium smartphones, for example the Samsung edge-type Galaxy phones or Apple's latest iPhones. A plastic-based OLED has several advantages especially in mobile devices - the displays are lighter, thinner and more durable compared to glass based displays.
Second generation flexible OLED displays can be bent by the user - these can be used for example to create foldable smartphones - the first range of which started shipping in 2019 and today these are quite popular. Rollable OLEDs are likely to enter the market soon, offering the ability to create scrollable devices. In 2019, LG launched the world's first rollable OLED device - the 65" Signature OLED TV R but in 2024 it discontinued this device as its price was too high for consumers.
Where to buy flexible OLEDs?
While several companies (including Samsung, LG, BOE and others) are producing OLED displays, it is not straightforward to find a good and reliable supply of these displays.
If you are interested in buying a flexible OLED panel for your project or device, look no further. Our OLED Marketplace offers several flexible OLEDs, which can be ordered through us with ease.
Researchers use a high-output flexible QD-OLED patch to encourage hair growth
Researchers at Korea's Gachon University, in collaboration with InnoQD and researchers from Chungbuk National University, have developed a new QD-OLED patch that can encourage hair growth. The patch can also measure heart rate at the same time.
The researchers used a flexible OLED device, and covered it with quantum dots that emit near-infrared (NIR) light. The OLED device is a tandem blue OLED device, that offers a high light output. The researchers say that when attached to the head, the patch encourages hair collicle cell growth, with a measured improvement of 23% in hair growth.
Ares Materials announces an investment with Denka to bring its films and materials to the flexible OLED industry
US-based Ares Materials announced that it Japan's Denka invested in the company, with an aim to expand its high-functional materials business. Denka invested via its corporate VC that is jointly managed with Pegasus Tech Ventures.
Ares Materials developed a design technique that utilizes materials informatics (AI) for using enethiols as a raw material and possesses the technology to produce high-performance optical films using the design technique. The company says its optical films offer high performance, low cost and a reduced environmental impact.
Inuru's flexible OLED holo tags - hands on review
A few months ago Inuru started shipping its range of OLED-powered stickers, or "holo tags" as the company refers to them. These are battery-powered flexible stickers that can be used for laptops or any other use.
The company was kind enough to send us three stickers, from their latest Cyberpunk range. These stickers cost around 20 Euros, and there are many alternative designs. The idea is that the flexible stickers include a small OLED, a battery and a button that lights up the OLED for a few seconds. The whole device is said to be waterproof, but I did not test it.
Inuru says that the lifetime of the OLED is about 5,000 hours. As the battery is limited, though, they say that each sticker is limited at around 2,500 clicks. Some of them use a red OLED, and some a blue one.
BOE and Omniply to co-develop materials and processes for flexible display manufacturing
BOE Technology Group and Canada-based Omniply Technologies announced a co-development agreement, with an aim to develop new materials and process technologies for display manufacturing.
It turns out that the two companies have been working together for almost 2 years, hoping to bring Omniply's technology into BOE's next-generation flexible OLED fab. BOE hopes that Omniply's technology may enable lower cost production of OLED displays, and the production of more eco-friendly displays. It also has the potential to be used in flexible sensors and microLED products in the future.
Reports suggest Samsung is accelerating its rollable smartphone project, aiming to launch it in 2025
According to a report from Korea, Samsung is progressing with its rollable OLED development project, and the company aims to launch its first rollable smartphone in 2025. When fully opened, the phone will sport a very large 12.4" display. Interestingly, Samsung apparently will implement an under-the-display camera solution.
Samsung's acceleration of its rollable phone project is seen as the Korean device maker's response to Huawei's tri-folding smartphone, the Mate XT. It is seen that this was an embarrassment for Samsung, that recently also to witness LG Display's leading over it with tandem OLED production. It will remain to be seen whether Samsung's acceleration will lead to problems in quality and reliability - which happened when it launched the world's first foldable phone back in 2019.
Researchers from Korea develop high performance stretchable OLEDs based on rigid 3D islands and horseshoe connectors
Researchers from Korea's KAIST, in collaboration with Dong-a University and ETRI have developed a new stretchable OLED structure that is made from 3D rigid islands, or bumps. These so-called 3D-Pop islands remain unchanged as the display itself stretches and so maintain excellent performance.
The OLED islands are connected with parts that are curved in shape (similar to a horseshoe) that can be deformed while still operating normally, even at 500% tension. The whole structure can simultaneously utilize hinge-type rotation and tension of the bending connection connector, and is so not limited to a 2D plane. Even at 40% elasticity, the light emitting area remains at 85%.
Apple announces its 2024 iPhone 16 series, and the new Apple Watch Series 10, all with AMOLED displays
Yesterday Apple announced its 2024 iPhone 16 series, and its latest smartwatch devices - all based on OLED displays. We'll start with the the iPhone 16 that offers a 6.1" 2,000 nits (HBM) 1179x2556 Super Retina XDR LTPS AMOLED, while the iPhone 16 Plus offers a larger 6.7" 1290x2796 display. Both phones are based on Apple's latest 3nm A18 chipset offering improved performance and AI support.
The iPhone 16 Pro has a more advanced 6.3" 120Hz 2,000 nits (HBM) 1206x2622 LTPO Super Retina XDR OLED. The 16 Pro Max offers a larger 6.9" 1320x2868 AMOLED. These new phones are based on Apple's 3 nm A18 Pro chip, offer a "huge leap in battery life", support Apple Intelligence and feature new a main camera.
Huawei officially launches its Mate XT tri-folding OLED smartphone
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.
BOE progresses with the construction of its 8.6-Gen flexible AMOLED line in Chengdu
Towards the end of 2023, BOE officially announced its plans for a 8.6-Gen flexible LTPO AMOLED line in Chengdu. The agreement with Chengdu's local government was signed in early 2024, and in April BOE announced it is starting to construct the new fab.
Yeolight confirms it is the OLED lighting supplier for Voyah's Zhiyin
Last month China-based Voyah announced a new international all-electric SUV called the Zhiyin, that includes several innovative technologies. The taillights of the car are OLED lighting based, with 33 individually controlled OLED units on both the upper and lower sections, creating unique light patterns. We assumed that Yeolight is the OLED panel supplier, and indeed now the company confirmed that.
In addition to the OLED taillights, the Zhiyin will also an AMOLED display - a "curved sliding screen" that can "slide to accommodate different user needs". While this is not confirmed, we assume that this is a similar display to the one Hongqi just revealed yesterday - a sliding rollable 14.2" AMOLED panel produced by Visionox.
