According to Japanese media reports, Sumitomo Chemical Co., Ltd., a Japanese general chemical company, has developed a new type of luminescent material that can be used to produce large-size OLED panels at low cost. The report pointed out that Sumitomo Chemical will invest billions of yen in funds to build production facilities at its Osaka plant this (2011) year, and plans to lead the world in volume production in early 2012.
Sumitomo Chemical's products will be sold to Taiwan, Japan and South Korea and other panel makers, with an annual production capacity of 400-500 million 40-inch TVs. The report pointed out that the new type of luminescent materials developed by Sumitomo Chemical Co., Ltd. may become an opportunity to promote generation alternation of television products (from LCD TVs to OLED TVs).
According to the report, luminescent materials are core materials for the performance of left and right panels, etc. The current mainstream products are materials called “low molecular†types, but this type of material is not suitable for the production of large-size panels, resulting in OLED panels at this stage. It is used only for small-sized products such as smart phones, and the Sumitomo Chemical Co., Ltd. will mass-produce luminescent materials as products called “polymersâ€, which can be easily printed by being made into a liquid, and are therefore very suitable for 40-inch or larger panel production.
According to reports, in terms of the cost of processing a luminescent material onto a panel, the cost of the polymer type product developed by Sumitomo Chemical Co., Ltd. can be reduced by a half as compared with a "low molecular" type product, and the biggest obstacle to practical application is " In terms of service life, the polymer luminescent materials developed by Sumitomo Chemical have also reached the necessary level.
