The upstream material manufacturing end of the OLED industry chain includes raw materials -OLED intermediates -OLED sublimation materials -OLED terminal materials, the middle reaches are OLED panels, and the downstream is consumer terminals such as TV sets, mobile phones, and VR devices. There are many materials composed of OLED, mainly anode materials, cathode materials, buffer layer materials, carrier transport materials, luminous materials several categories.

OLED materials mainly include two parts: light-emitting materials and basic materials, both of which account for about 30% of the material cost of OLED screens. OLED luminous materials mainly include red light subject/object material, green light subject/object material, blue light subject/object material and so on. OLED general materials mainly include electron transport layer ETL, electron injection layer EIL, hole injection layer HIL, hole transport layer HTL, hole barrier layer HBL, electron barrier layer EBL, etc. With the optimization of device structure, the types of materials are constantly increasing. The organic light-emitting layer material and the transport layer material are the key materials of OLED.

OLED terminal material production and organic material technology is in the hands of foreign companies. At present, OLED terminal manufacturers are mainly South Korea, Japan, Germany and the United States manufacturers, including South Korea Samsung SDI, LG Chemical, Toksan Metal, Doosan, Japan Idemitsu Xinggong, Botugu Chemical, United States UDC, Germany Merck and other companies. The main threshold restricting new enterprises is the patent of sublimed materials, and most of the current mainstream organic materials technology is owned by foreign companies, and foreign companies give these technologies patent protection. Domestic enterprises are mainly engaged in the production of OLED intermediates and crude monomers. Domestic OLED intermediates and monomeric crude suppliers mainly include Wanrun Shares, Xi 'an Ruilian, Puyang Huicheng, Beijing Agrea, Jilin Olaide, of which Wanrun Shares, Puyang Huicheng, Xi 'an Ruilian, etc., have achieved mass production and entered the global OLED material supply chain. The main industry barrier for OLED intermediates and monomer crude products is the recognition of downstream manufacturers, and these enterprises that have entered the OLED supply chain will benefit from the rapid growth of OLED demand. According to statistics, in 2018, the global and Chinese OLED materials market size was 1.258 billion US dollars and 1.517 billion yuan, respectively.

Domestic OLED organic material products are mainly intermediates and monomer crude products with low technical content, and high-purity sublimation products are less, only Beijing Ding Material Technology Co., LTD. Ding Material Technology ";) Guangdong Aglea photoelectric Materials Co., Ltd. and Jilin Olaide photoelectric Materials Co., Ltd. are produced by several manufacturers. However, in view of the development prospects of OLED in the Chinese market, it is believed that domestic OLED material companies with technical advantages and layout in OLED organic materials will be expected to break the game.
