Low-temperature curable OC photoresist

Low-temperature curable OC (Over Coat) photoresist is specially designed for heat-sensitive flexible display substrates to protect temperature-vulnerable devices such as OLEDs by lowering process curing temperature.In conventional display panel manufacturing, standard OC photoresist (used as protective and insulating layers) requires high-temperature curing at approximately 200–230 °C. Nevertheless, organic light-emitting materials inside OLEDs, together with flexible substrates including PI, PE
