A large opportunity lies in the development of devices in a flexible form factor that can operate without deterioration in performance, allowing them to be more robust, lightweight and versatile in their use. In order for flexible displays and photovoltaics to be commercially successful, they must be robust enough to survive for the necessary time and conditions required of the device. This condition has been a limitation of many flexible, organic or printable electronics. This highlights the fact that beyond flexibility, printability and functionality, one of the most important requirements is encapsulation as many of the materials used in printed or organic electronic displays are chemically sensitive, and will react with many environmental components such as oxygen and moisture.

These materials can be protected using substrates and barriers such as glass and metal, but this results in a rigid device and does not satisfy the applications demanding flexible devices. Plastic substrates and transparent flexible encapsulation barriers can be used, but these offer little protection to oxygen and water, resulting in the devices rapidly degrading.
