Benefits of technology
The present invention aims to create a reliable electrode that is strong and durable without reducing its electrical conductivity or optical quality. This objective should be reached without changing the configurations of organic light-emitting systems and without adding excessive costs.
Problems solved by technology
However, this ITO layer has a number of drawbacks.
Firstly, the material and the high-temperature (350° C.) deposition process for improving the conductivity generate additional costs.
