[MEET1-2(Invited)] Better but Worse, the Challenging Promise of Micro LEDs
Micro LED, Display, Light Extraction Efficiency, Internal Quantum Efficiency, External Quantum Efficiency
More than $4B have been spent over a decade to explore high-brightness, low-power MicroLED displays. The key challenge is maintaining power efficiency as MicroLEDs scale down to ~5µm. MicroLEDs scaling down results in better light extraction efficiency, but worse internal quantum efficiency. This conundrum is quantified here using physics-based models.
