MANHASSET, N.Y. Japan-based Idemitsu Kosan Co. Ltd. and Sony Corp. have signed a memorandum of
understanding to jointly develop organic light-emitting diode (OLED) luminous materials, and cross-license one another’s OLED-related patents.
Idemitsu developed what they claim to be the brightest blue-light organic luminous material in 1997, based on their molecular engineering and organic synthesis technologies. The company has since continuously been developing luminous materials for the mid-large size OLEDs, as well as combination technology for materials and OLED component technologies.
Sony’s mass-produced OLEDs were adopted in the company's PDA (Personal Digital Assistant) products from Sept. 2004. The company is now developing new technologies to produce a mid-large size OLED panel.
By sharing their complementary OLED related technologies, Idemitsu and Sony will develop new OLED luminous materials with high luminescence efficiency for lower power consumption,
high brightness and color reproduction for high-definition content, high response time for moving images, and long durability.
