Flexible phone screen? Is that real?
Yes it is. Now we can enjoy the flexibility of flexible organic-light emitting diode (FOLED) screen. A FOLED is a type of organic light-emitting diode (OLED) incorporating a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited. This enables the device to be bent or rolled while still operating. Currently the focus of research in industrial and academic groups, flexible OLEDs form one method of fabricating a rollable display. Then, what is the history of it?
