Micro-light emitting diodes (μLEDs) with remarkable advantages are becoming mainstream in next-generation display technologies such as augmented reality/virtual reality displays. However, further development of μLEDs still faces significant challenges, including mass transfer yield. Here, we report color conversion layer (CCL)-based, full-color, highly efficient μLED arrays as a solution to address this challenging issue. Further amalgamating CCL with color purity enhancement film enables us to realize 7 μm×7 μm subpixel fluorescent arrays with a color gamut of 95.34% in DCI-P3, resulting in an overall 1588 PPI (pixel per inch). Our results provide a promising technique for fabricating higher PPI-based next-generation display technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
