Toshiba Matsushita Display Technology (TMD) and Idemitsu Kosan have jointly developed a small-molecule OLED panel for mobile equipment, which they claim has one tenth the power consumption, and a lifetime of up to 30 times longer, as compared to existing TMD models.

The joint development involved the TFT substrate design technology and element design technology of TMD; development of materials by Idemitsu, including RGB light-emitting materials and peripheral materials which offer high-efficiency and low-power consumption; and joint evaluation of the optimum combination of materials by both parties.

As a result, TMD and Idemitsu succeeded in achieving an OLED display of 2.2-inch QVGA (240×320) format suitable for mobile equipment applications, with power consumption of 100mW (based on typical movie screen images, defined by 30% brightness of a full-white screen) and luminosity half-life of 60,000 hours (based on a full-white screen at 200 cd/m2).
