53‐1: Invited Paper: Novel Design of Microstructure Package Design to Enhance Optical Efficiency of Micro‐LED Displays

In this work, we propose a novel microstructured packaging design for Micro‐LEDs. By using a high‐refractive‐index transparent resist, we enhance the light extraction efficiency of Micro‐LEDs significantly. Additionally, a high‐reflectivity white resin material combined with lens microstructures is adopted to converge the light from a wide viewing angle, increasing the brightness at the 0°viewing angle by approximately 53%. This novel design improves the light utilization efficiency and reduces color deviation issues caused by the strong sidewall light emission of Micro‐LEDs. Furthermore, the patterned design of the black matrix cover layer reduces light loss and enhances the contrast of the display product, realizing high‐quality image display for Micro‐LED products. This paper provides a new scheme for enhancing the performance of Micro‐LED display products and promotes the industrialization process of Micro‐LED technology.
