Abstract

Various display devices utilize colloidal quantum dots (QDs) for photoluminescent (PL) and electroluminescent (EL) applications

owing to their exceptional optical properties, including sharp emission bandwidths, tunable emissions spectra, and

photoluminescence quantum yields approaching unity. Since the commercialization of PL-based devices, researchers have

shifted focus to the commercialization of EL-based devices and patterning processes. Over the past decade, the performance

of EL devices has been dramatically enhanced through the meticulous optimization of the device architecture. In addition,

solution-based QD patterning techniques have advanced, off ering methods that minimize damage to the coated QDs while

preserving their intrinsic properties eff ectively. Recent innovations include the development of ink formulations that improve

the stability of QDs under ambient conditions and the use of photolithographic and soft lithographic techniques to achieve

high-resolution patterning. This article reviews the recent advancements in various EL-based devices and solution-based

methods for QD patterning, highlighting their potential to enable more complex, multi-color displays, and their implications

for next-generation consumer electronics.
