Demand for larger mobile displays is accelerating as telecom players push mobile content and mobile advertisements to compensate for shrinking growth in voice revenues. The solution is to unroll the display when needed and simply store away when not in use. Polymer Vision has announced that the company develops its rollable display and first models are on assembly line. This rollable display will be used in Readius 3G mobile phone and it’s supposed to be available before the end of the year.
