MicroLED displays have long been heralded as the future of display technology, promising unparalleled brightness, response times, and energy efficiency. But almost two decades after the first MicroLED prototypes, widespread commercial availability remains elusive.
In a paper published in the Journal of Physics: Photonics, researchers from academia and industry collaborated to provide an updated roadmap of the progress and remaining challenges facing MicroLEDs. They trace the origins of MicroLEDs back to the early 2000s, when researchers realized that shrinking LEDs to the microscale enabled intriguing physics like enhanced spontaneous emission and lower lasing thresholds. Practical applications soon followed, with MicroLEDs eyed for next-generation displays, VLC, and biomedical devices
