Electronic paper prepares for video

By Ivan Noble, BBC News Online science staff – “Flexible paper-like colour computer displays that can show moving video are under development by the Dutch electronics giant Philips.

Two scientists at the company’s research facility in Eindhoven describe the latest step forward in e-paper technology in the journal Nature.

Philips – and other firms like E Ink in the US – have already succeeded in making prototype flexible displays, but their refresh rates – the speed at which they can turn a single dot on or off – have been slow.

These previous prototypes have used a principle called electrophoresis to switch pixels on or off.

But now the Philips team says its new technology can significantly improve the refresh rate using a faster effect called electrowetting.”
