The issue isn't the budget, it's the fact that e-ink display cost hasn't really gone down in 5-10 years.

I was expecting 2022 to have $10 e-ink displays I could use to replace the 2x16 and 4x16 LCD screens in my Arduino projects.

But nope, anything over 2" is tens of dollars still - as it was 10 years ago.

I'm finding 4" displays for $36 and 7" for under $70.

For a 4x16 LCD, the 2" displays are probably most comparable, and are in the same price-range as the equivalent LCD (about $8--$12).

2" e-ink multi-colour displays with far higher resolution ... are about $20.

I'm no fan of E-ink's patent monopoly, but you're being ever so slightly disingenous / unreasonable here.

Ha! I am the same with OLED. Ever since I saw a video recorded in an OLED lab, where one of the guys had a transparent foil, looking just like those for the overhead projectors in high-school in the 80's, connected to a HDMI cable. He switched it on and a movie was playing on that foil. He bent it, rolled it and said, this could be cut to any shape and size.

I would be in DIY heaven, if one could buy such foil by the meter, for a sensible price. Just imagine, what kind of displays for DIY devices one could accomplish!
