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.

With display screens in mobile phones and camera module pixels increasing, demand for brighter flash LED has grown. Global flash LED shipment volume reached 1.03 billion units in 2013, according to a report by LEDinside. It is anticipated that shipment volume will grow to 2.07 billion units by 2018. Revenue for flash LED in 2013 hit US $561 million and is anticipated to reach US $764 million in 2018. 

Chinese investors have recently approached Crystal Optotech to verify whether the company is currently producing sapphire panels for Chinese smartphone manufacturer Xiaomi. Crystal Optotech responded it has yet to produce sapphire for mobile phone application.
