Abstract

Colloidal quantum dots (QDs) are a new type of high-quality optoelectronic material with a radius close to the Bohr radius of the exciton. Its special size effect enables QDs to achieve high-purity three primary color luminescence

continuously adjustable emissions and wide color gamut by adjusting the size of QDs. In addition

the special core-shell structure ensures that QDs have good photo/thermal stability. At the same time

QDs also have excellent solution-processable properties. Since being discovered in 1990s

QDs have become popular research materials in the field of display. Quantum dot light-emitting diodes (QLEDs) based on QDs have also been regarded as the most promising technology to replace organic light-emitting diodes. In the past few decades

QLEDs have achieved such great success to be regarded as one of the most promising materials in the display field. Therefore

researching

analyzing and optimizing the performance of QLEDs devices are of great significance for accelerating their commercial marketization. From the perspective of QLEDs devices optimization to the large-area QLEDs production

the research progresses of domestic and foreign researchers in the direction of constructing efficient and stable QLEDs for display applications are summarized

and the difficulties and challenges we are going to face in the future development of QLEDs are aralyzed.
