Panasonic launches a new stretchable film, suitable for OLED substrates and encapsulation films

Panasonic announced a new thermoset stretchable film for printed electronics, called Beyolex. Panasonic targets several applications for its new film, including OLED substrates and encapsulation film.

Beyolex is based on a proprietary non-silicone thermoset polymer chemistry developed by Panasonic researchers at the company's Electronic Materials laboratory in Osaka, Japan. The film features softness, conformability, high temperature resistance, and ultra-low permanent deformation after stretching.

SDC collaborates with ULVAC to develop 8.5-Gen vertical OLED deposition

As demand for larger mobile OLED displays, for laptops, tablets and monitors is on the rise, there are reports that Samsung Display is considering building a 8.5-Gen AMOLED fab dedicated for laptop and IT displays.

This new fab will be the first 8.5-Gen RGB OLED deposition fab, and Samsung is looking into new technologies to enable OLED deposition on larger substrates. It is reported today that SDC is developing, in collaboration with ULVAC, vertical deposition technology.

OLED webinar to introduce OLED lighting manufacturing and R2R production

An AILU (Association of Industrial Laser Users) webinar, scheduled for September 15, will introduce the basics of OLED lighting, discuss the choice for the right substrate and encapsulation material as well as the current status of roll-to-roll processing. The webinar is sponsored by 3D Micromac, the industry leader in laser micromachining and roll-to-roll laser systems.

The webinar will also show results from the EU-funded LAOLA project, which is a collaboration between German and Japanese companies and research institutes. The LAOLA project, led by the Fraunhofer FEP, develops the use of ultra-thin flexible glass as a substrate and encapsulation material in roll-to-roll technology for this purpose.

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.

Will Samsung's next foldable phone use ultra-thin flexible glass?

Samsung is working on its next foldable phone, which according to leaks will be called the Samsung Galaxy Z Flip. According to XDA's Max Weinbach, the new phone will be use ultra-thin flexible glass, instead of polyimide.

In November 2019 Samsung indeed signed an exclusive deal with Korea's Dowoo Insys to supply ultra-thin glass (UTG) for future foldable OLED devices. Samsung is aiming to switch to glass as its current foldable OLEDs which are protected by a plastic cover are highly prone for scratching and are very fragile.

The Fraunhofer FEP, NSMAT and MSSMC developed an OLED on a stainless steel substrate

The Fraunhofer FEP institute, in collaboration with Nippon Steel & Sumikin Materials (NSMAT) and Nippon Steel & Sumitomo Metal Corporation (NSSMC), developed a new OLED lighting prototype that is made on a stainless steel substrate.

The researchers say that a stainless steel substrate has several advantages compared to glass or plastic - it has excellent thermal conductivity and excellent barrier properties. The lighting panel features an extremely homogenous OLED light, thanks to the planarization layer developed by NSSMC. The prototype panel was produced at the Fraunhofer's R2R research line.

The US DoE awards five new OLED project grants

The US Department of Energy announced 11 new solid state lighting projects grants, out of which five are related to OLED technologies (the rest are for new LED technologies).

We already posted on two of these grants which were awarded to Pixelligent. In addition to Pixelligent, OLEDWorks were also awarded with two SBIR Phase 1 projects, one for an ultrathin, curved, high-efficiency OLED light engine that will reduce the cost OLED lighting and the second for the development of a novel substrate and encapsulation process.

The DoE grants two new SBIR OLED lighting projects

The US Department of Energy (DoE) announced new SBIR and STTR grants for solid state lighting projects. The DoE announced five new grants out of which two are related to OLED technologies.

Pixelligent Technologies were awarded an SBIR project titled "Light Extraction for OLED Lighting with 3-D Gradient Index". This project will explore the application of a novel and unique 3D gradient index (GRIN) layer to improve the efficiency and lifetime of OLED devices. Using such a unique structure, OLEDs could be produced that achieve the theoretical maximum extraction efficiency.
