Eindhoven-based Polymer Vision is to unveil a colour version of its rollable display next week at the Society for Information Display (SID) conference in Los Angeles, alongside a higher resolution monochrome version.

Both are paper thin and have a minimum roll radius of 6mm.

The 65,000 colour display has a resolution of 127dpi, while the monochrome display offers 254dpi, "which is the highest resolution e-paper display ever shown", claimed Polymer Vision.

The firm's displays are based around electrophoretic technology which is reflective, needs no power to hold an image, and does not suffer the moisture problems dogging flexible OLEDs.

In the second half of this year, the firm aims to launch Readius, its e-reader/ 3G phone which measures 115x57x21 and unfolds to reveal a 125mm 320x240 display.

A 400MHz ARM11 processor inside runs Windows CE, and the device includes a MicroSD card slot.

"This year we will launch our first commercial product, while at the same time our prototypes bring the future closer where mobile devices will be equipped with large rollable displays," said CTO Edzer Huitema.

Polymer Vision spun out of Philips at the end of 2006.

Its manufacturing arm, formerly the independent company Innos, acquired by Polymer Vision in 2007, is based in Southampton.
