Idemitsu's OLED factory in Chengdu is the company's third and largest-capacity (12 ton/year) production, and Idemitsu hopes it will enable it to strengthen its OLED materials sales in China. This new fab will increase Idemitsu's total OLED materials production capacity to 22 tons / year.

In 2017 Idemitsu said that it aims to increase its production capacity in 2018 by 70%. In 2018 Idemitsu signed an agreement with Toray to co-develop OLED materials and an agreement with LG Chem to share their OLED material patents. In 2019 Toray and Idemitsu announced that the companies have jointly developed a red TADF OLED device that is the world's most efficient emitter at 46 cd/A.
