Quantum dot light emitting diodes QLEDs are a printable thin film electroluminescent technology that can deliver exceptional color and efficiency at low cost of manufacture for display and solid‐state lighting applications. However, while most literature reports focus on the performance of individual test pixels, examples of working display prototypes have been sorely lacking. We report on our progress developing QLEDs for near‐to‐eye and direct view display applications. Both a 4″ diagonal active‐matrix bottom‐emitting monochrome QLED display and an 800×600 SVGA top‐emitting monochrome QLED microdisplay are reported on and their performance summarized. Contract printing of high‐resolution RGB QDs is also demonstrated as a milestone towards full‐color displays.
