Philips Electronics is tinkering with a prototype e-book with roll-out display, which is pretty amazing. It’s based on Philips Polymer Vision’s PV-QML5 rollable display reference design, they will be showing it at the upcoming Internationale Funkausstellung (IFA) in Berlin, Germany, September 2-7.
“Rollable displays will revolutionalize the level of convenience with which one can access greater volumes and quality of information while on the move,” avers Philips Polymer Vision CEO Karl McGoldrick.
The prototype device combines form factor (small) and large display (readable), which are a couple holy grails with portable devices. It conclusively proves that roll-out devices are becoming an option for mobile devices. This screen has a 320 x 240 resolution, 4 gray levels and is 5-inches wide.
The new 5-inch PV-QML5 rollable display has a decreased radius of curvature, improved operational and mechanical lifetime and paper-like viewing contrast. Significantly, this is a superior and improved version of the world’s first rollable display prototype introduced by none other than Philips’ owner of Polymer Vision back in February 2004.
When not actively used, the featherweight, ultra-thin portable device can be rolled up into a small housing with a radius in curvature of less than 7.5 mm. Cute, isn’t it? With four gray levels, the monochrome display provides paper-like viewing comfort with a high 10:1 contrast ratio for reading-intensive applications. Even in bright daylight, the display is easy to read. Using a bi-stable electro-phoretic display effect from E Ink Corp, the display consumes an exceptionally low amount of power.
