Abstract

Colloidal quantum dot (QD) display is expected to be promising technology for the next generation display due to the advantages of QDs. In this work, we designed and fabricated 6.6 inch inkjet printed red QD‐OLED device, 3‐stack blue OLEDs (BOLEDs) with top‐emission structure acted as backlight. Red QD layer acted as converted materials, which exhbitted high quantum efficiency, high luminance, high color purity and improved wide viewing angle of output emission. We believe that inkjet‐printed QD color convert layer with AMOLEDs would be promising candidate for next generation display in the near future.
