Yet E-ink is cheap enough for price tags at big box stores…?

  E-ink gets exponentially more expensive with size, and an e-ink panel in this keyboard would have to have a fairly decent resolution and refresh rate, whereas the price tags are usually 1-bit color, low res, and barely have to refresh

  My understanding is that the price of the displays is largely dependent on the size of the screen due to manufacturing techniques. I don't know the specifics unfortunately.
