If nooks operate in the same way as kobo screens it's not actually

That would be quite expensive in terms of battery use.

Apparently the nook simple touch does have an IR matrix

And Nooks are
known for very long battery life. My wife will go for over a week,
easily, reading several hours per day.

My kobo will too, it was apparently the last kobo model to use an IR
matrix (and I expect kindles last for ages too).
