This is not exactly the first prototype of a flexible OLED panel but it is the first prototype from Toshiba, measuring just 0.1 mm in thickness. Along with Samsung, Sony and LG, Toshiba is a strong proponent of OLED technology.
Flexible OLED panel from Toshiba
OLED is only available in small size smartphone displays but it has a support from a range of major companies, including Toshiba.
At SID 2011 Toshiba exhibited a 3-inch OLED prototype that measures just 0.1 mm in thickness. The panel is printed on a plastic substrate, which means that it is also flexible. More impressively, it weighs just 1 gram.
Toshiba also says that their OLED prototype panel has a “long” lifetime, but without mentioning any numbers to back up that claim.
Toshiba plans to mass produce OLED panel in 2014 or 2015 trailing behind Samsung and LG.
Also, see this video of a flexible OLED panel. This is not Toshiba's prototype.
