The next generation of display technologies promises crisp, bright, colorful images that don't require a backlight -- but they're incredibly expensive and rigid in form factor.
Until now. Sony demonstrated in Japan on Wednesday an ultra-thin 4.1-inch OLED that can roll as tightly as a radius of 4 millimeters and still operate normally -- a world's first, according to the company.
How thin is ultrathin? Approximately 80?m thick, with a resolution of 432 by 240 pixels at 121 pixels per inch.
The roll-up OLED display touts a contrast ratio of 1,000:1 and manages a brightness level of 100 cd/m2.
