What is it about?

LED/MicroLEDs have extraordinary properties such as high luminance, efficiency, and lifetime. As we continue to scale down the dimensions of the light emitting area, microLED technology is being viewed as the next-generation AR/VR display technology. The technology has received little commercial focus in its non-display applications, which can take advantage of improvements in the fundamental microLED properties. Additionally, it also needs modification in some of the critical electrical and optical properties. This article highlights the non-display application areas and the electro-optical integration techniques required for the optimum performance of the systems.

Why is it important?

This article highlights the extent of possibilities microLEDs technology offers, which goes beyond the much-anticipated display application. The reader will also benefit from understanding the advanced electro-optical integration techniques that modify the fundamental microLED properties.


I hope this review will create interest in the research community to look at microLEDs beyond traditional applications. The researchers working in other areas, such as photonic crystals, quantum dots, and more-- may see potential unique applications combining the two technologies and design systems with improved efficiency and performance.
