The active-matrix light-emitting diodes (LEDs) array is a main development direction of the next-generation display technology, which requires high efficiency, wide color gamut, high contrast, high resolution, fast response, and cost-effectiveness. Perovskite CsPbX3 nanocrystals emerge as promising candidates, offering tunable emission wavelength, remarkable photoluminescence quantum yields, cost-competitiveness, and integration with diverse solution-based pixilation methods. Based on these unique properties from lead halide perovskite and nanomaterials, CsPbX₃ nanocrystals demonstrate a formidable potential for active-matrix LEDs. However, the integration of perovskite LEDs with active-matrix remains a challenge. The efficiencies of both red and green perovskite LED have exceeded 28%, approaching the theoretical limit of light out-coupling efficiency for planar LED. The existing efficiency of sky-blue perovskite LED reaches 20%, while the efficiency of pure-blue perovskite LED is still lagging. Thus, improving the efficiency of pure-blue perovskite LED becomes imperative to realize full-color display. In addition, the slow electroluminescence response time caused by ion migration in perovskite under an electric field is also a critical issue, which is a limiting factor for the development of high-refresh-rate active-matrix display using perovskite LEDs.

To enhance the device performance of red, green and blue quantum dot LEDs, it is crucial to control the surface structure at the nanoscale of metal halide quantum dots. Previous extensive studies carried out on the atomic composition of the surface, the types and coordination modes of surface ligands, ligand density and developed various surface reconstruction strategies and ligand application paradigms to improve the quality of metal halide quantum dot crystals and the integrity of the surface lattice. This review systematically demonstrates recent research achievements, summaries the principles and ligand functions of different reconstruction strategies, and represents single-color demo of quantum dot LEDs integrated with active-matrix, providing a reference for the further development of full-color active-matrix displays based on metal halide quantum dots.

Summary and Aspects

In this review, we summary various strategies for surface reconstruction of quantum dots, discuss the selection and design principles of surface and ligands for quantum dots applied in electroluminescence, and finally represent recent research progress in the integration of lead halide and its quantum dots with active-matrix displays. To further promote the realization of efficient full-color active drive LEDs, a key interim goal in the next step is to break through the pixelization technology for lead halide quantum dots, thereby achieving the integration of red, green, and blue colors onto the active-matrix TFT backplane simultaneously. Many scientific and technical issues need to be solved in this process. For instance, how to ensure that the morphology and photoelectric performance of the lead halide quantum dot film are not damaged during pixelization. The need for high resolution means that thousands of pixel points should be arranged very closely, having high requirements for the precise positioning of pixelization technology. In addition, avoiding color crosstalk caused by ion exchange between pixel points is also a technical problem that must be solved due to the easy ion exchange of halogen ions.
