We developed triple nozzle evaporator that can make collimated organic molecular beam. We can reduce inner pressure below final nozzle 1/150 times lower than general evaporator by using triple nozzle structure and recycling path. As a results, the angular flux distribution of triple nozzle evaporator is similar with the cosine to the 100 th graph. And 80% of total flux are concentrated within only ±8° angle region. We expect that it will be helpful to achieve ultra‐high resolution in AMOLED AR/VR and increase material utilization in AMOLED mass production.
