I can only think of one reason: patents. That's the equivalent of saying, "I wish it had transparent OLED display and yet there are no affordable devices like this". A good analogy would be like looking at the sports car market, and saying Ferraris aren't affordable because of patents. There's numerous reasons why display companies like E Ink and others are unable to make such panels "affordable" because their costs are higher than said price. The dominant reason that I'm aware of is volume. If you're not producing at least a million displays a month, then you can't justify building up a bespoke production line so instead you'll have to repurpose a modified LCD production line for your product and so you'll have lower yields. At larger sizes, you'll even have to kerf by hand. Don't even start thinking about laminating touchscreens, as you'll then start dropping your yields further. It is simple to prove this. Look at E Ink display pricing between say 2002 and today. Their sweetspot is the Amazon sized display and that price has declined dramatically because they achieved volume for only that display. Everything else has stayed around the same price or some have even gone up in price since there's no volume around it. People aren't interested in paying 6 grand for a 32 inch black and white panel and nobody is willing to pony up an order for a million of those even if they could get the price down to 1 grand. No volume, no affordable price. That's the simple truth of the display industry. Patents barely have any effect as far as I can tell. Everybody in the industry has them.
