Novel Design of Microstructure Package Design to Enhance Optical Efficiency of MicroLED Displays
Invited
Description:
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.
