Abstract

In terms of their use in displays, quantum dots (QDs) exhibit several advantages, including high illumination efficiency and color rendering, low‐cost, and capacity for mass production. Furthermore, they are environmentally friendly. Excellent luminescence and charge transport properties of QDs led to their application in QD‐based light‐emitting diodes (LEDs), which have attracted considerable attention in display and solid‐state lighting applications. In this review, we discuss the applications of QDs which are used on color conversion filter that exhibit high efficiency in white LEDs, full‐color micro‐LED devices, and liquid‐type structure devices, among others. Furthermore, we discuss different QD printing processes and coating methods to achieve the full‐color micro‐LED. With the rise in popularity of wearable and see‐through red, green, and blue (RGB) full‐color displays, the flexible substrate is considered as a good potential candidate. The anisotropic conductive film method provides a small controllable linewidth of electrically conductive particles. Finally, we discuss the advanced application for flexible full‐color and highly efficient QD micro‐LEDs. The general conclusion of this study also involves the demand for a more straightforward QD deposition technique, whose breakthrough is expected.
