P‐11.13: Organic‐Perovskite Bilayer Color Conversion Media for Full‐Color Displays

Color conversion media (CCM) are crucial for realizing cost‐effective, high‐resolution micro‐LED and OLED displays. In this work, we developed green and red organic‐perovskite bilayer CCM that combine the PLQY and color purity of perovskite quantum dots (PeQDs) and the strong blue absorption of perylene‐based organic emitters. The bilayer with thickness of 300 nm showed over 99% blue absorption and PLQY of 77% and 61% for green and red CCM, respectively.
