Idemitsu and Sony to Jointly Develop Materials for OLED

via PRNewswire

SAN DIEGO , Nov. 30 /PRNewswire/ Idemitsu Kosan Co., Ltd. (hereafterIdemitsu) and Sony Corporation (hereafter Sony) have signed a Memorandum OfUnderstanding (MOU) on November 28, 2005 to jointly develop new superiorOrganic Light-Emitting Diode (hereafter OLED) luminous materials. And topromote the joint development, they have agreed to the mutual use of eachcompany's OLED-related patents, i.e. material patents and component patents.The formal contract is expected to be signed at the end of January 2006 .

OLED is a self-luminous display, which emits light by running an electriccurrent through organic luminous materials. As a result of its simplestructure, whereby the organic luminous layer is placed between two glasspanels, no back-light system is required. This leads to a much thinnerdisplay. OLED is widely considered to be the most viable next-generation flatdisplay, showing excellent color reproduction capability and high-speedresponse to moving images.

Idemitsu developed the world's brightest blue-light organic luminousmaterial in 1997, based on their molecular engineering and organic synthesistechnologies. Idemitsu has since continuously been developing new luminousmaterials for the mid-large size OLEDs. In addition to materials development,Idemitsu is aggressively working on new technologies such as combinationtechnology for materials, OLED component technologies, etc.

Sony is developing various material and component technologies, andpresented a 13" OLED panel in February 2001 and a 24" OLED in January 2003 ,based on low temperature poly silicon TFT (Thin Film Transistor) technologies.Sony's mass-produced OLEDs were adopted in the company's PDA (Personal DigitalAssistant) products from September 2004 . And now, Sony is working ondeveloping new technologies for the realization of a mid-large size OLEDpanel.

By sharing their complementary OLED related technologies, Idemitsu andSony will develop new superior OLED luminous materials, boasting excellentfeatures such as high luminescence efficiency for lower power consumption,high brightness and color reproduction for HD contents era, high response timefor moving images, long durability, etc.
