Sumitomo Chemical Co. has developed a new technology which can reduce production costs of large-format OLED panels to a great extent. The company has developed a new chemical pigment material for manufacturing OLED panels that targets to cut the production cost to half of the current deposition method. The company plans to enter quantity production by 2019 and sell to panel manufacturers in and outside Japan, expecting reduction of prices for OLED TVs to expand the market. The current deposition method requires expensive equipment and lots of the chemical pigment materials are wasted. The light-emitting elements of red, green and blue are supplied by Idemitsu Kosan Co. of Japan, Merck from Germany, and so on. The new printing method can reduce production costs because it requires less manufacturing processes than the deposition method but has a drawback of difficulty of coating light-emitting pigment evenly on the panel plate, which becomes more difficult when the panel sizes get larger. The new pigment that Sumitomo Chemical has developed is expected to reduce colouring of the light-emitting pigments on to the panel. Sumitomo Chemical said it has developed new manufacturing equipment for the printing method. To develop the new pigments, the company has cooperated with foreign panel makers and JOLED, which was established by integrating the OLED business division of Sony and Panasonic in 2015. JOLED plans to develop 21.6-inch display for medical use by using the new OELD panel produced in the printing method and market this autumn.
