Universal Display announced it has awarded a $150,000 SBIR phase I program from the US DOE to develop low cost single layer outcoupling solution for OLED lighting. UDC says that to date no one has demonstrated an approach to achieve desired extraction efficiency targets in a thin form factor and cost-effective manner. UDC's solution has the potential to increase the light extraction by greater than a factor of two while being cost-effective and compatible with low-cost OLED manufacturing techniques.
UDC is also developing single-layer thin-film hybrid organic-inorganic encapsulation layer (they call this UniversalBarrier). Obviously these two technologies can be combined to create thin-film low-cost and efficient OLED lighting panels.
