Historic company listing


DowDuPont logoUS-based DowDuPont was established in 2015 as a merger between DuPont and Dow Chemical. The new company was a material company active in agriculture, materials science and specialty products.

18 months after the merger, DowDupont was split into three companies, and Dupont and Dow became public companies again.

Daejoo Electronic Materials

Daejoo Electronic Materials logoDaejoo Electronic Materials, based in Korea, manufactures materials for the electronic industry. The company's materials are used in a wide range of applications such as LEDs, CFLs, epoxies, glass materials, phosphors and more.

For the OLED industry, Daejoo used to offer blue host and emitters in addition to ETL, EML, HTL and HIL materials. The company stopped its OLED project a while back.


Konica Minolta Pioneer OLED

Konica Minolta Pioneer OLED logoKonica Minolta Pioneer OLED was established in 2017 as a joint venture between Konica Minolta and Pioneer to accelerate automotive OLED lighting. The new company was formed with an initial capital of 490 million yen (about $4.4 million) and a focus on OLED lighting for automotive applications.

The new "strategic alliance" was to combine KM's roll-to-roll flexible OLED production equipment and technology with Pioneer's achievement in OLED panel mass-production and market rollout and its car electronics business know-how. In 2019 the company was dissolved following Pioneer's withdrawal from the OLED lighting market.


Dash-Insights is an independent technology market research and consulting company founded by global display expert Sweta Dash in 2015 focusing on entire display value chain and emerging display technology markets including flexible OLED and Quantum Dot.

Atom Microelectronics

Atom Microelectronics logoUS-based Atom Nanoelectronics was established in 2013 to develop innovative, scalable and high throughput fabrication technologies.

The company's technology was based about HiPCOT single-walled carbon nanotubes, and using these material Atom developed fully-printed CNT-TFT backplanes for AMOLED displays.

In addition to the backplane technology, Atom has invented a new OLED architecture in which the light-emitting function and electronically driving circuits are monolithically integrated, leading to less fabrication processes and low price.

It seems as if the company is no longer in business.

Molecular Glasses

Molecular Glasses logo (2018)US-based Molecular Glasses developed a new class of organic semiconductor materials for OLED displays, branded as OLEDIQ. OLEDIQ materials can be deposited by evaporation or in solution-based processes.

Molecular Glasses focused on host materials for OLEDs, and offered red, yellow, green and blue host materials.

The company seems no longer to be in business.


Organic Lights

Organic Lights logoOrganic Lights, based in Germany, is a global supplier of OLED lighting panels and OLED lamps.

Organic Lights can supply the entire range of LG Displays' OLED panels via its online shop.

Power OLEDs

Power OLEDs logoUK-based Power OLEDs was established in December 2013 to develop OLED stack materials - including high triplet-energy, high performance hole transporters, electron transporters, electron injectors, host and emitters.

The company seems no longer to be in business.

Solvay OLED

Solvay OLED, based in Pittsburgh, US, was established in 2014 by Solvay after the acquisition of Plextronics. Solvay OLED, an internal start-up owned by Solvay, handled all of Solvay's OLED activities - mostly focused on soluble HIL and HTL OLED materials - but also developing small-molecule hosts and other technologies.

The company had two dedicated laboratories located in Pittsburgh and in Korea as well as scale up capabilities in France. Solvay OLED was dissolved in 2016 as Solvay decided to exit the OLED market.
