Explanation:

OLED displays can be fabricated on flexible plastic substrates: One of the main advantages of OLED displays is their flexibility. Unlike Liquid Crystal Displays (LCDs), OLED displays can be fabricated on flexible plastic substrates, making them suitable for curved or flexible devices such as curved smartphones or wearable devices.

Roll-up displays embedded in clothing can be made using OLEDs: Due to their flexibility, OLED displays can be used to create roll-up displays that can be embedded in clothing or other flexible surfaces. This allows for innovative applications and designs, such as wearable technology.

Transparent displays are possible using OLEDs: OLED displays have the capability to be transparent, which means they can be used in applications where a see-through or transparent display is desired. This opens up possibilities for augmented reality, heads-up displays, and other transparent display applications.
