Current microLED die sizes and future roadmap and trend?

This is an excellent chat by Eric Virey (Yole showing how LED dies are expect to shrink in size, going from mini-LED region (e.g., 125x255mm) to ultrasmall microLED region (5x5um?). This driver is essentially because it increases PPI and drives down cost as well as transfer time/cost since more LEDs are produced per wafer. To sustain this trend, many other technologies need to evolve from more efficient small-sized red LEDs to microbumps to better tiling and metallization techniques and transfer technologies.
