The company in question, Kateeva, has developed an innovative printing process, which “sprays” a protective layer and encapsulates the OLED units of the flexible display. This coating protects the organic diodes from both of their archenemies, oxygen and water. The inability to develop such an encapsulation method allegedly prevented Samsung, the smartphone maker that still reigns supreme, from manufacturing its YOUM displays on a large scale. The Galaxy Note 4 was rumored to sport a flexible display, but this is not among the most probable speculations regarding the upcoming phablet.
Another issue that needed to be solved was the implementation of transparent ITO (indium tin oxide) electrodes, which are used in touchscreen displays. These electrodes are miniature and transparent, but quite fragile – they would easily break if you bend the display. Fortunately, another company, named Canatu, has found a way to solve the problem – it ditches ITO electrodes for carbon nanotubes, which are not only more conductive than indium tin oxide ones, but also survive stretching, flexing, and bending quite well.
So, bring it on, smartphone industry!
