Cathode IR‐Drop is one of the major barriers for large area top‐emission AMOLED displays with low power consumption. A solution based on making an electrical connection between the top cathode and a prefabricated auxiliary electrode in the backplane was demonstrated using ConducTorr TM self‐assembled cathode patterning process. Mid‐size top‐emission AMOLED panels for IT and large‐size panels for TV can be enabled by such damage‐free patterning process.
