are e-Paper displays really still that expensive to manufacture or is this a monopoly thing?
@hache well, I know the small ones are dirt cheap, I have one that plugs into a Raspberry Pi, but I want one I can read books on
@noiob yeah, fair point.
@hache like, I love the small price displays, they're better than they need to be and really useful for stores, but they're a) tiny and b) slow, especially the two-color ones
@noiob they're really hard to make with double digit refresh rates and harder still with colour
@kyra the monochrome ones are really expensive too
@noiob colour ones are 4 monochrome ones occupying the same space
@kyra I figured, but considering they're made of bubbles with the color inside it must be a lot more complicated to create small squares with different colors than just one big monochrome screen
@kyra actually, two-color ones probably just have two kinds of pigment in the screen, that's why they're that slow (and much faster when used in monochrome mode), the full-color ones are the really complicated ones
@kyra btw, fun fact: eink screens have temperature sensors because the properties of the fluid in the display change with temperature
@noiob Our local budget grocery store (literally called "No Frills") switched entirely to small e-ink displays for all their price displays. So I gather they aren't THAT expensive at the right volume.
