Imec has developed cost-effective fine-pixel photolithography for manufacturing ultra-high resolution OLEDs. Imec, and its development partner Chunghwa Picture Tubes (CPT) , aimed to push pixel density beyond 1000 ppi. Imec and CPT have verified that a novel photolithography process can allow for ultrafine OLED patterns. The proposed technique does not require using fine-metal masks to ...
