TMDisplay a joint venture between Japan’s Toshiba Corp and Matsushita said it has developed organic light-emitting diode (OLED) displays with the world’s longest product life span and lowest power consumption.
TMDisplay developed a 2.2-inch OLED panel QVGA (240×320) with a lifetime of 60,000 hours and power consumption of 100 mW. Sony Corp (6758.T: Quote, Profile, Research, Stock Buzz), which launched the world’s first OLED TVs late last year, said in October the product had a life span of about 30,000 hours of viewing, about half that of Sony’s LCD TVs.
Toshiba Matsushita Display Technology said it aims to start commercial production of the advanced OLED panels by March 2009 for cellphones and other mobile devices. It has yet to decide the size of production.

PRESS RELEASE:
Toshiba Matsushita Display Technology Co., Ltd. working in joint development
with Idemitsu Kosan Co., Ltd. completes organic EL element featuring low power
consumption and extended lifetime -
Toshiba Matsushita Display Technology Co., Ltd. (TMD) and Idemitsu Kosan Co., Ltd. (Idemitsu) have jointly developed a small-molecule organic electroluminescent (EL) display panel for mobile equipment, with 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 the world’s highest level of performance*** for an organic EL display screen of 2.2-inch QVGA (240×320) format suitable for mobile equipment applications, with power consumption of 100 mW (based on typical movie screen images, defined by 30% brightness of a full-white screen) and luminosity half-life of 60K hours (based on a full-white screen at 200 cd/m2).
Since the fine organic EL layer formed on the glass substrate is a light-emitting device, an organic EL display can achieve high-contrast and high-definition images. These displays can also realize high speed motion on the screen without blur and with a wide viewing angle. Furthermore, the organic EL displays feature resource-saving features, such as lower power consumption, and require less material to build the display, since no backlight peripheral components are necessary, contributing to the display’s thinness.
