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$7\mathrm{\mu m}\times 7\mathrm{\mu m}$ 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.

基于颜色转换技术的具有更高效率的超高分辨率全色 Micro-LED 阵列

具有显着优势的微型发光二极管（μLED）正在成为增强现实/虚拟现实显示等下一代显示技术的主流。然而，μLED 的进一步发展仍面临重大挑战，包括传质率。在这里，我们报告了基于颜色转换层 (CCL) 的全色高效 μLED 阵列作为解决这一具有挑战性问题的解决方案。进一步将 CCL 与色纯度增强膜结合，使我们能够在 DCI-P3 中实现色域为 95.34% 的7 μm × 7 μm亚像素荧光阵列，从而实现整体 1588 PPI（像素每英寸）。 $7\mathrm{\mu m}\times 7\mathrm{\mu m}$我们的研究结果为制造基于更高 PPI 的下一代显示技术提供了一种有前途的技术。
