QLEDs: High‐Resolution Pixelated Light Emitting Diodes Based on Electrohydrodynamic Printing and Coffee‐Ring‐Free Quantum Dot Film (Adv. Mater. Technol. 10/2020)

To satisfy the resolution and film morphology requirements for pixelated quantum dot light emitting diodes (QLEDs), electrohydrodynamic printing (EHD printing) combined with mixed solvent method are presented to realize coffee-ring-free pixelated QLEDs with 306 pixels per inch. Their great potential in high-resolution QLEDs device manufacturing is demonstrated in article number 2000401 by Yongqing Duan, Zhouping Yin and co-workers.
