TOKYO, Aug 20 (Reuters) - A joint venture between Japan's Toshiba Corp (6502.T) and Matsushita (6752.T) said it has developed organic light-emitting diode (OLED) displays with the world's longest product life span and lowest power consumption.
OLED panels are expected to be a promising next-generation display as they are thinner and offer brighter colours than liquid crystal displays (LCD) and plasma panels, but a shorter life span has been seen as a drawback.
Toshiba Matsushita Display Technology, owned 60 percent by Toshiba and 40 percent by Matsushita Electric Industrial Co, said on Wednesday it has developed a 2.2-inch OLED panel with a lifetime of 60,000 hours and power consumption of 100 mW. Sony Corp (6758.T), 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.
The venture has developed the new panel in cooperation with Idemitsu Kosan Co (5019.T), a Japanese oil refiner active in OLED materials development.
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.
Shares in Toshiba were down 0.8 percent at 664 yen in afternoon trade, while Matsushita, the maker of Panasonic brand electronics, fell 1.7 percent to 2,270 yen, underperforming the Nikkei average .N225, which gained 0.3 percent. (Reporting by Kiyoshi Takenaka; Editing by Michael Watson)
