Micro-LEDs offer efficiency, brightness, and faster response times, but manufacturers must first overcome significant hurdles.HANK HOGAN, CONTRIBUTING EDITORSmall, as in microscopic, LEDs promise brighter displays and longer-running mobile devices, but only after manufacturers overcome several challenges. Known as micro-LEDs, these semiconductor chips are generally 10× smaller in width and length than traditional, standard LEDs. They also have different principal markets. “The main application targets are direct-emission displays for smartphones, TVs, wearables like AR displays, smart-watches, and so on,” said Eric Virey, senior analyst for LEDs and displays at the technology market research firm Yole...Read full articleRelated content from Photonics MediaARTICLESNitride-Based MicroLED Emits Pure Red LightA microLED developed at KAUST is able to efficiently emit pure red light and could help in the quest to develop full-color displays based on a single semiconductor.
