  Samsung Display Co., Ltd.

Description:

We developed an 8.5 generation inkjet printer that can produce 220 ppi QD-OLED panels. We implemented a high-resolution inkjet printing system in three major development directions: inkjet stage correction technology, optimization of head ejection and ink circulation process, and printing pattern S/W technology. We have finally achieved production of 220 ppi (27” 5K) monitor panels.
