Looks like Rohinni is making progress. Congrats to them for their second coverage in FastCompany. This article teases a bit more detail then what we knew from two years ago: They are apparently developing technologies to more accurately place the “micro LEDs” in a consistent layout for uniform lighting.
Commercially available chip-scale-packages (CSP’s) are down to under 1mm square sizes. So what’s a “microLED”? Perhaps 1/10th of a mm square? I’m still curious as to the same thing I questioned in my blog two years ago: Isn’t there a law of diminishing returns for the kerf waste (cutting width) of chopping up a wafer into “micro LEDs”? Is this stuff going to compete effectively on cost with OLED?
I’m wondering now if this is still a die-in-conductive suspension design?
And Idaho of all places! I wish they could have launched around 2011, when I was stuck in Boise at Micron’s hapless attempt to launch a LED division!
