Visionox has shown a prototype rollable, flexible AMOLED panel. It is a 4.6″ unit with 800 x 480 resolution. The prototype has a curvature radius of sub-3mm and a thickness of 20µm.
The plan, according to Visionox, is to mass-produce its new panel within two years. A video of the prototype, which obviously still has some defects, can be seen at http://tinyurl.com/nela5xo.
