We have analyzed the most recent trends in μLED display intellectual property landscape. After a decade of low activity, filings have been growing exponentially since 2012. This analysis identifies key technologies, highlights unusual solutions, and provides insights on the status of μLED developments.
MicroLED is a promising display technology. There are however still many technical challenges that need to be tackled before it is ready for consumer products. Mass transfer of the microLED chips is the elephant in the room, but many others could prove as challenging and possibly even derail the microLED roadmap.
Availability of standard, high volume production tools and processes enabled the commercialization and commoditization of LCD and OLED. For microLED, the lack of processes standards and the proliferation of technology paths hinders the development of high‐volume manufacturing tools. This paper discusses the challenges for equipment manufacturers attempting to capture the microLED opportunity. While various technology bottlenecks remain, the microLED display industry can leverage on existing expertise and equipment from the display, semiconductor, LED and photonic industries to accelerate industrialization.
For MicroLED displays to be economically viable, microchip transfer and assembly technologies with micron‐scale accuracy, and throughputs at least 5 orders of magnitude higher than traditional pick‐and‐place and bonding equipment are required. This paper discusses existing and emerging technologies, from the lab to commercially available solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
