Flexible OLED (Organic Light Emitting Diode) enables the device in which it is used to roll or bend while still operating. An OLED emits light due to the presence of thin films of organic semiconductors of thickness approximately 100 nanometers. The regular OLEDs are fabricated on a glass substrate, whereas flexible OLEDs use flexible plastic such as polyethylene terephthalate (PET). The replacement of glass with PET also reduces weight of the device. Flexible OLED market is in the nascent phase; however it is expected to skyrocket in the near future owing to the fast growth of electronics industry. OLEDs also find their application in the production of electronic paper or bendable displays that can be integrated into clothing, wallpaper or other curved surfaces.
