I agree, it's expensive if you compare the price to an LCD. But as this is e-paper technology with completely different use cases, the manufacturing costs are still high. Keep in mind that, currently, e-paper is not a substitute for classic LCD panels. Where e-paper shines for me is very low battery consumption. For example, the mentioned device can hold up to 6 months without a single battery recharge and is completely wireless.

WaveShare has e-paper modules between 5" and 7" costing around 50 EUR. You can drive them either from a Raspberry Pi or a ESP8266 microcontroller. We're using a small one as an instrument panel on our boat https://github.com/meri-imperiumi/dashboard#readme https://github.com/meri-imperiumi/dashboard#readme

  Nice project! Yes they are indeed cheaper. It's really up to your taste. The device I'm using is already in a casing and comes with a sophisticated software that can render any modern HTML5 on the device with full JS support.

    Like say, running Firefox on a raspberry pi?

Amazon can somehow put those displays in a Kindle for what... 90€? Maybe they have some mix-calculation going on with book sales, but in comparison a Kindle should cost around 400-500€ when looking at those numbers here.

  yeah those are subsidized devices

    Clearly making a loss with me then. Sorry, Amazon! :-)

    Right, Kindles presumably have a high attachment rate (owners buy more ebooks) so Amazon can subsidize based on that attachment rate, and also the base model Kindle prices include direct advertising subsidization. (Check the "without ads" SKUs prices for something somewhat more comparable.) Don't forget too many of the screen prices above are essentially single screen "retail" prices and Amazon would likely have better bulk wholesale prices worked out in their supply chains.
