Kaiyuan Chemical, based in Tianjin, China is involved with chemical research and manufacturing. The company supplies pharmaceutical intermediates and ingredients and also high-tech electronic materials.

The company produces several OLED intermediates and claims it has been supplying materials to both LG and Samsung.

Kanto Chemical, established in 1944 in Japan, develops and manufactures fine chemicals, reagents, and chemicals for the electronics industry. For the OLED industry, the company offers hole transporting electron blocking materials that it developed in collaboration with NHK.

US-based Kebotix develops next-generation materials using advanced artificial intelligence, machine learning and robotics technologies. The company automates the scientific method using a proprietary closed-loop R&D process, in order to predict and produce new chemistries in a self-driving lab.

Kebotix targets several markets, including the OLED material market, for which it aims to introduce its first emitter materials in 2022.

LG Chem (part of the LG Group) is developing and marketing chemicals and electronic materials. For the OLED display market, LG Chem is offering OLED stack materials.

In July 2017, Idemitsu Kosan and LG Chem announced a new collaboration agreement that will allow both companies to use each other OLED material-related patents in certain areas.

LG Chem was producing OLED lighting panels, but in 2015 the company sold the OLED lighting business unit to LG Display is a $135 million deal (LGD later withdrew from the market). LG Chem also had an OLED circular polarizer business, which was sold in 2023.

Light Polymers, established in 2013 in San Francisco, is developing products based on lyotropic liquid crystals for applications such as displays (LCD and OLEDs), lighting, solar panels and packaging.

In March 2017 Light Polymers announced a $24.3 million financing round to scale up its OLED circular polarizer solution.

UK-based Lomox, established in 2017, is a materials company that is focused on photo-crosslinkable and photo-patternable emissive and charge-transporting materials for printable OLED applications.

LORDIN is an early-stage company established in 2020 that aims to develop efficient blue OLED emitter materials based on triplet harvesting. The company also offers services to the OLED industry.

LORDIN has raised just over $6 million in funds, and is looking to IPO in the future. The company hopes to develop a commercial OLED emitter by 2024.

Luminescence Technology (or Lumtec) is a Taiwanese manufacturer of organic chemicals for the OLED, OPV and OTFT markets.

Lumtec offers both evaporable and soluble OLED materials (HTL, HIL, ETL, EBL, Host materials and dopants). The company offers phosphorescent and TADF emitters.

In 2019 Lumtec announced that it started to produce OLED lighting panels, mainly for the automotive market. The company's production capacity is around 150,000 50x35 mm panels per month. The company is planning to expand its production capacity to 600,000 units per month.

US-based Margik (previously Light and Charge Solutions) was established in 2019 to design next-generation electron and hole transport materials (ETM, HTL) for organic electronic devices, including OLED lighting and display panels.

The company says its materials offer high thermal stability and high resistance to moisture.

Material Science was established in Korea in 2014 with an aim to develop OLED materials. The company currently offer ETL, HTL, EIL, EBL materials in addition to red and green host and emitter materials.

In 2017 Material Science announced it has developed an efficient blue OLED fluorescent emitter and host system. The company also develops TADF emitters.
