A four-layer flexible PCB is the key to routing data and power to so many LEDs. Putting that many addressable LEDs — even tiny 1 mm x 1 mm ones — across a rounded surface isn’t exactly trivial.

Sponsored] Flex and rigid-flex PCBs are widely used across various industries due to their unique combination of flexibility, durability, and design versatility. Among the leading providers, PCBWay ...

has successfully developed 124-layer PCB technology for wafer inspection equipment designed for next-generation high bandwidth memory, such as HBM (Note 1) mounted on AI semiconductors.
