摘要：

Micro-LEDs have promising development potential in display applications because of their outstanding performance. Achieving a full-color display based on micro-LEDs is one of the most important issues in commercial applications. In this paper, an effective method based on quantum dots and blue micro-LEDs was developed. Using an etching method, a thick black matrix was fabricated to reduce crosstalk and form a thick bank for quantum dots. Quantum dots were deposited in a thick black matrix using inkjet printing technology. With blue micro-LEDs, inkjet-printed quantum dot films can realize effective color conversion. The integrated blue micro-LEDs and red/green quantum dot films can achieve full-color displays without color filters, because the blue light leakage in the color conversion film can be reduced by the quantum dots themselves. The results suggest that inkjet-printed quantum dots are a promising way to achieve full-color micro-LED displays.
