Microlight-emitting diodes (Micro-LEDs) are considered indispensable for next-generation display technologies. However, their further development faces numerous challenges, such as the difficulty in achieving high-yield mass transfer and the use of environmentally harmful quantum dot color conversion techniques with suboptimal efficiency. To address these issues, we propose several key solutions. First, we developed nontoxic and environmentally stable organic−inorganic hybrid materials, utilizing color conversion techniques integrated with photolithography to replace the time-consuming and costly mass transfer process. Additionally, we refined the aspect ratio and color conversion efficiency of the microarray, and optimized the fabrication process to produce color conversion microarrays free from nanoparticle residue and without the need for protective layer curing. We successfully fabricated monochromatic 5080 PPI and panchromatic 2540 PPI, 4 × 4 μm ultrahigh-resolution color conversion microarrays. This color conversion layer is merely 3 μm thick, achieving green and red conversion efficiencies of 84.14% and 71.20%, respectively. Furthermore, the overall color gamut coverage reached 99.11% in the DCI-P3 standard. Stability measurements at 60 °C and 90% relative humidity for 10 days showed that green and red color conversion efficiencies decreased by less than 2%. Our research results bring further technological innovation to the field of micro-LED display applications.
