Colloidal quantum dot (QD) light-emitting diodes have great potential in display applications. However, their commercialization remains a challenge due to the difficulty in achieving high-resolution patterning of QDs without degrading their optical properties. To address this, researchers have developed a nondestructive method for ultrahigh-resolution QD patterning. By blending QDs with a photocrosslinkable polymer, the approach preserves their optical properties and boosts efficiency and lifetime, paving the way for development of next-generation display technologies.
