Photolithographic QD OLED displays achieved over 40% photo conversion efficiency in QD on encapsulation technology, suggesting improvements over traditional manufacturing methods.
In this paper, full‐color photolithographic QOE (QD on encapsulation) display with 326 PPI was realized. QOE shows merits of wide viewing angle, high color gamut and free offine metal mask. Compared with QD‐OLED with adhesive process, QD on encapsulation (QOE) with low post baking temperature has been demonstrated to be more superior in cost, efficiency and accuracy. It is noteworthy that photo conversion efficiency (PCE) and DCI‐P3 color gamut of QOE are over 40% and 120%, respectively.
