Bridgestone has unveiled a colour ePaper display that could revolutionise the technology.

Though ePaper displays are already making their mark in eBook readers such as the Kindle they are currently hampered by one to two second refresh times, and their black and white displays.

Yet, despite being better known for its tyres than its technology, Bridgestone's latest prototype display may solve many of these problems.

Breaking with the E Ink crowd, Bridgestone has developed its own QR-LPD full-colour 13in display. As with E Ink the display only uses power when changing screen, but unlike E Ink the screen refreshes every 0.8 seconds, allowing for smooth text entry using a stylus pen and smooth animations, graphics and screen transitions.

Bridgestone has revealed that the majority of its development time has been spent achieving that 0.8 second screen refresh. It's previous prototype screen was A4-sized and required around 10 to 15 seconds to refresh the page.

The company's not revealed any dates for a commercial release and has stressed that it's still currently in prototype stage.
