> As in, it's more likely you get a dead pixel on a larger screen.

Aside from the ink capsules and higher voltage (though still very low), E ink is almost identical to LCD and probably slightly easier to make. There's a TFT (which can have a larger footprint, since it doesn't need to be transparent) on the back, an LC or E ink capsule layer, and an ITO electrode. Dead pixels are almost always caused by damage or defects in the TFT.

I wouldn't say it's artificially out of reach, though- setting a line up to produce large panels is a high opportunity cost. If anything is artificial about it, it's that you presumably can't buy E ink capsules yourself. With enough effort you might be able to separate the top glass from an LCD TV, dissolve the LC, and replace it with E ink, but I have no idea how you'd do that. No promises it wouldn't burn out the TFT immediately.




Acronym-expansion as a service:

TFT: Thin-film transistor

LC: Liquid crystal

ITO: Indium-tin oxide

LCD: Liquid crystal display (though this one's widely known).

(Please expand acronyms on first use. Even, or especially, where they strike you as well-known or obvious.)

False. E-ink film, especially color, is definitely more complex to get right than LCDs. Sure, e-ink displays have the same TFT layer underneath just like LCD displays, but the e-ink pigment and film is tricky to make.
