I'm really curious about the reproducibility. The color is decided by the bandgap and the bandgap is tunable by voltage, but how temperature dependent is it, and how much does production variability impact it?

I image these displays could have color sensors attached to self-calibrate.

Or the variability is low and all you need is very precise voltages.

I think the first versions will be RGB displays with fixed colors, just no longer needing mass transfer. You could use tens of subpixels per pixel, reducing all worries about color resolution.

Make these into e.g. 1x1cm mini displays and mass transfer those into any desired display size.
