Flexographically Printed OLED Indicator and Passive Matrix Displays*

Sinovia Technologies is using flexographic printing to fabricate bottom-emitting OLEDs. This is enabled by our proprietary transparent conductive anode, developed in house. Our anode is additively printed roll-to-roll at under 100 micron resolution, serving as the foundation of an entirely roll-to-roll fabrication process. Flexographic printing allows us to create arbitrarily-shaped OLED designs without any need for etching or photolithography. This includes dynamic segmented and passive matrix displays with a cost structure on par with the LCD and LED assemblies used in IoT and other smart product applications.
