At this point it seems like the biggest limiting factor of scale is the vias, not the LEDs themselves. If they made LEDs with 3 pads, where the outer 2 pads are connected together, you could make a matrix on a single-sided board with no vias.
- zokier 3y agoFor one-off, I wonder if you could just glue the leds together and hand-wire (very carefully) with some magnet-wire. Throw in some kapton tape to insulate everything.
- tomn 3y agoI wonder how it would look to connect the columns with 0201 zero-ohm resistors between the LEDs (jumping over the rows lines). If you want a square pixel pitch it might work out nicely.
- crote 3y agoYou don't really have the clearance for that. The gap between the two pads of the resistor should be at most 0.3mm, and more realistically 0.2mm - any larger and they're going to tombstone. 0.1mm traces with 0.1mm clearance are manufacturable so it could fit in a 0.3mm gap, but realistically you probably want to do 0.15mm traces & clearance to keep the cost acceptable.
