Overprinting OLED, LG Chem acquires DuPont's soluble OLED material technology

LG Chem will acquire DuPont's soluble OLED materials technology.

According to the agreement between LG Chem and DuPont, LG Chem's acquisitions include all of DuPont's tangible assets, intangible assets, namely soluble OLED material technology and patents, 540 materials and process patents, and DuPont research and production facilities.


The specific amount of the transaction has not been announced recently, but the industry estimates that the value is about 200 billion won ($176 million) to 300 billion won.

The printed OLED mainly uses a solvent to melt the OLED organic material, and directly prints the material on the surface of the substrate through a high-precision nozzle to form an RGB organic light-emitting layer. Compared to traditional vapor-deposited OLEDs, the printing process maximizes the use of materials to reduce losses.

Fu Dong, general manager of Juhua Printing Display, pointed out that the printed display is the best technical route to solve the problem of large-size OLED. Whether it is Samsung, JOLED, or Huaxing Optoelectronics, etc., they are actively deploying print display technology. Fu Dong expects that G8.5/G11 mass production technology based on printed display technology is expected to mature around 2020.

DuPont has 20 years of experience in the field of light-emitting layers and inkjet printing equipment, and has a large number of technical patents. Through this acquisition, LG Chem immediately acquired all the core technologies of soluble OLED materials.

Since 2015, LG Chem has been researching and developing soluble OLED materials with certain technological achievements. The company plans to seize the market by establishing a stable OLED material supply system, and LG Chem will gain greater advantages through the core technologies acquired through R&D accumulation and acquisition.

LG Chem said: "Through this transaction, we have gained strong market competitiveness in the field of soluble OLED."
