As if we needed any further convincing of the wonderful potential of flexible displays, a Japanese company called SEL has developed a high-resolution screen that can be rolled to a tight four-millimeter radius, allowing it to wrap around the edge of a smartphone while still working.

Made possible through the use of highly flexible but durable CAAC—or C-Axis Aligned Crystal—oxide semiconductors, the OLED display not only eliminates a bezel around a screen altogether, it allows controls like volume or muting to be facilitated through software and the on-screen UI—meaning they're completely customizable. It could also completely revolutionize wearable devices, since the display technology is able to achieve similar brightness and resolutions to the flat display technology used in devices today.
