interesting point but for a given luminance in nits the area doesn’t matter since it is cd / m^2 so assuming that there is a “cheap variety” of LED wafer material that outputs say 2000 nits for a low current, then a small area — say 20x20um for the subpixel size would save some cost for sure. I would estimate about the area of the subpixel would be about 30 times smaller than most indicator type low cost LEDs — which are in the sub 1mm^2 area range. So we can find the 30X factor but still need around 300X cost reduction still to get a 10000X reduction in price. Ultimately the Display should be around $100 or less, so if you can buy an entire wafer for $800 or so then you have something, but as far as I know most 12 in wafers with zero processing done to them are more like 1k. Then put them thru a fab and add value and run the fab and the cost goes up a ton. And we need 3 different wafers.. so anyway, I’m worried cost is just going to really hurt this approach for a long time.
