A rollable display is a flexible display that can be rolled up into a scroll. Technologies involved in building a rollable display include electronic ink, Gyricon, and OLED.
Electronic paper displays which can be rolled up have been developed by E Ink. At the CES 2006, Philips showed a rollable display prototype, with a screen capable of retaining an image for several months without electricity.[1] As of 2007 Philips Polymer Vision expected to launch a 5-inch, 320 x 240-pixel rollable display based on E Ink’s electrophoretic technology.
Some flexible organic light-emitting diode displays have been demonstrated.[2] The first commercially sold flexible display was an electronic paper wristwatch.
A rollable display is an important part of the development of the roll-away computer.
