Flexible Organic Light Emitting Device

Flexible Organic Light Emitting Device


FOLEDs are organic light emitting devices built on flexible substrates. Flat panel displays have traditionally been fabricated on glass substrates because of structural and/or processing constraints. Flexible materials have significant performance advantages over traditional glass substrates.

For the first time, FOLEDs may be made on a wide variety of substrates that range from optically-clear plastic films to reflective metal foils. These materials provide the ability to conform, bend or roll a display into any shape. This means that a FOLED display may be laminated onto a helmet face shield, a military uniform shirtsleeve, an aircraft cockpit instrument panel or an automotive windshield.

Ultra-lightweight, thin form: The use of thin plastic substrates will also significantly reduce the weight of flat panel displays in cell phones, portable computers and, especially, large-area televisions-on-the-wall. For example, the weight of a display in a laptop may be significantly reduced by using FOLED technology.

Durability: FOLEDs will also generally be less breakable, more impact resistant and more durable compared to their glass-based counterpart.

Cost-effective processing: OLEDs are projected to have full-production level cost advantage over most flat panel displays. With the advent of FOLED technology, the prospect of roll-to-roll processing is created. To this end, our research partners have demonstrated a continuous organic vapor phase deposition (OVPD) process for large-area roll-to-roll OLED processing. While continuous web FOLED processing requires further development, this process may provide the basis for very low-cost, mass production.
