Plastic fantastic makes rollable e-paper a reality

A polymer-based display developed by Dutch company Philips under the PolymerVision brand, can be rolled up like a newspaper. The PolymerVision PV-QML5 announced on March 2 is an ultra-thin (100µm) featherweight 320 x 240 pixel active-matrix display, five inches from corner to corner. Each layer of the matrix is flexible allowing the whole sheet to be rolled up. While flexible plastic displays have been discussed for several decades, this device is perhaps the first to become a commercial reality. According to Philips, it generates four shades of gray and can be read under almost any light conditions, even sunlight, as though it were real newsprint, but with the obvious advantage that the contents can be changed.
