Destined to become "best seller" if Aldi/Walmart/Ikea could offer 75" with 4K RGB for $150-200. This would be a perfect indoor wall decor in any room, kind of ultimate poster.
A 31.5" color e-ink poster is ~$1700[1]. I do not know what these large panels cost but (possibly due to low yields) eink panel prices seem to scale superlinearly with area. I would expect a 75" panel that is five times larger to cost more than a used car.
Anything can become a "best seller" if you are able to arbitrarily lower the price by multiple orders of magnitude -- $500 luxury cars would fly off the lot but would not be profitable.
Lol you can hardly get a 7.5’’ for that price. I once looked into making a few programmable ePaper “posters” for myself, and noped out of it when I saw the price.
My understanding is that the yields on large eink panels are horrendous (which is why they cost thousands and thousands of dollars). I would definitely buy one at that price though.
