One of the leading companys for flexible OLEDs are Universaldisplay

UDCs Flexible Display Development Program

Universal Display Corporation is actively engaged in research and development to bring this exciting FOLED technology to market. Key challenges relate to flexible substrates, flexible packaging and encapsulation. The Company’s program is focused on developing the requisite technologies to realize the Universal Communication Device and products like it.

Flexible Substrates
Today, the primary substrate candidates are thin plastics, such as PET and PEN polyester films. While these materials offer many attractive features, they also currently impose limitations with respect to thermal processing and barrier performance. Companies are developing coatings for these substrates as well as new plastic substrates to compensate for these constraints. Universal Display Corporation is actively working with a number of these companies.

The novel use of metallic foil substrates for FOLEDs is a complementary approach to the glass and plastic displays that Universal Display Corporation has made possible through its proprietary FOLED and TOLED® top-emitting technologies. Flexible metallic substrates provide excellent barrier properties, thermal and dimensional stability over a broad temperature range, and cost-effectiveness. They also offer potential near-term integration with backplane technology for active-matrix FOLED displays.
