Sony, LG.Philips unveil flexible Oled displays

Show off 2.5in and 4in screens respectively

Sony sees Oled technology as important for its future products and is putting a lot of research and development resources behind screens like that unveiled this week.

The screens are different from today's LCD and PDP (plasma display panel) screens in that Oled pixels use an organic material that emits its own light, so no backlight is needed. That means the screens consume less power and can be made thinner. Oleds also handle fast-moving images better and offer good colour reproduction.

At the Consumer Electronics Show in Las Vegas in January Sony showed off prototype televisions based on larger, non-flexible 11in and 27-inch OLED panels. Thanks to the lack of a backlight the 11in prototype was just 11mm thick but displayed a vibrant, colourful image. Sony plans to have its first Oled TVs on sale in Japan this year.

Last week in Tokyo Sony unveiled its latest Oled TV prototypes, which appeared to be close to commercialisation. The sets had an integrated digital TV tuner and could also accept a high-definition input via an HDMI (high-definition multimedia interface) connector.
