Fraunhofer COMEDD collaborated with Orthogonal Inc to develop a new approach for OLED micro-structuring. The new patented technology, called Orthogonal Photolithography allows direct patterning of organic material on CMOS-backplanes.
This technology can enable high-brightness (5000 cd/m2) high-resolution OLED microdisplays. This is because it can be used to create direct-emission OLED microdisplays. All current microdipslays on the market use white OLED subpixels with color filters. Fraunhofer is also developing direct-emission OLED microdisplays using flash-mask-transfer-lithography (FMTL) technology.
