Recent Advances in Transfer Printing of Colloidal Quantum Dots for High-Resolution Full Color Displays
https://doi.org/10.1007/s11814-024-00301-3
Abstract
Quantum dots (QDs) have garnered signifi cant attention in the advanced optoelectronic devices due to their unique luminescent
properties, including size-tunable emission, high photoluminescence effi ciency, exceptional chromatic purity, and
superior photostability. To achieve based high-defi nition full-color displays, it is critical to develop a precise patterning
process capable of accurately depositing red, green, and blue QD subpixels at desired locations with high resolution. Among
various patterning techniques, transfer printing has emerged as a promising method for achieving high-defi nition pixels while
preventing cross-contamination between diff erent colored subpixels. This technique involves transferring QD patterns to a
target substrate using an elastomeric stamp. This review provides a comprehensive overview of the latest research trends
in three types of transfer printing processes: additive-transfer printing, subtractive-transfer printing, and intaglio-transfer
printing. We examine the strengths and limitations of each technique and showcase key applications in QD light-emitting
diodes that utilize transfer-printed QDs.
