The quantum dot light‐emitting diodes (QLEDs) by inkjet printing are promising candidates for lighting and display applications of the industry. Herein, we report an inkjet printed QLED, showing that the luminance of red QLED is as high as 185, 607 cd/m 2 , the external quantum efficiency reaches 12.6 %, and the lifetime (T 95 ) is 549 h @ 1000 cd/m 2 , which is one of the highest reported for a very primitive device structure.
