Samsung researchers demonstrate a 'commercializable' stretchable OLED display

Researchers from Samsung Advanced Institute of Technology (SAIT) developed a new stretchable OLED display, that features stable performance and high elongation possibility. Samsung says that this research is the first one to prove the commercialization potential of stretchable devices.

The new stretchable OLED was integrated with a photoplethysmography (PPG) sensor in a single device. The PPG sensor is used to measure the user’s heart rate in real-time - which can be displayed on the OLED display.

Researchers from Yonsei University develop highly stretchable OLED devices

Researchers from Yonsei University developed a new OLED device that is highly stretchable. The researchers managed to build the entire device, including the substrate, conductive wires, electrodes and OLED layers, from stretchable materials.

The researchers say that this is the first time that the complete display device was produced from stretchable components, unlike previous efforts which have mainly focused on connecting small rigid OLED devices together to create a stretchable device.

LG Display to lead a major R&D project in Korea to develop stretchable displays

LG Display announced that it has been selected by the Korean Ministry of Trade, Industry and Energy to lead a national large-scale project to develop stretchable displays. LGD says that this project is a major part of the MOTIE's drive to help Korea's next-generation display industry.

LGD says that the goal of this project is to develop stretchable display products with a 20% elongation rate by 2024. The company believes such displays can vastly widen the scope of applications that displays can be applied to. 21 companies, universities and research institutes will take part in this government-supported project.

KAIST researchers developed a stress-relief substrate for stretchable OLED displays

Korea's KAIST institute researchers developed a new stress-relief substrate that is suitable for the creation of stretchable OLEDs that can maintain their performance under high-strain deformation.

The researchers say that the new stress-relief substrates have a unique structure and is made from a patterned "upper substrate" with bridges on top of pillars that decentralize the stress on the device.

Samsung demonstrates a 9.1" stretchable AMOLED prototype

Samsung Display is set to demonstrate a 9.1-inch stretchable AMOLED prototype during SID 2017. This display can stretch up to 12 mm when pressed, and still maintain its high resolution (which SDC did not specify).

This is an exciting development - but we're all waiting for Samsung to first commercialize its foldable OLEDs, and only then can we expect to see commercial rollable and stretchable displays.

Researchers manage to print a stretchable OLED cirtuit

Researchers from Michigan State University (MSU) developed a stretchable circuit that includes an OLED display, produced entirely using an ink-jet printer.

The researchers used special developed inks to produce both the circuits and the organic elements - and they say that the ink was also used to produce the substrate, but that seems rather unlikely.

IHS sees the flexible OLED market growing at a CAGR of 44% from 2014 to 2024

IHS says that flexible displays are an "increasingly important segment of overall display market revenues", and by 2024 flexible displays (mostly OLEDs) will grab 15% of the total flat panel display market.

IHS Flexible OLED market forecast 2014-2024

Flexible display production will grow at a compound annual growth rate (CAGR) of 44% from 2014 - to reach $23 billion in 2024. The growth may actually accelerate when display makers start to produce rollable, foldable and stretchable panels and devices.

Highly stretchable and foldable supercapacitors enabled by graphene

Flexible OLED displays are quickly becoming a reality, and it is expected that starting from 2015 we're going to start seeing foldable and eventually even stretchable OLEDs used in commercial devices. But for really flexible devices, all components must be flexible too.

While flexible batteries are already being developed, another possibility is to use a flexible supercapacitor. Researchers from MIT developed an extremely stretchable supercapacitor based on crumpled graphene paper.
