Very cool!
I wish E-ink displays were a bit more affordable. The 13 inch one is £229.50.
Does anyone know why they are still so expensive, at least at large sizes?
- eckelhesten 18d agoPatents and greed in a combination.
- pjerem 18d agoYou have to distinguish the fake color e-ink that are used in mass consumer products which are actually black&white e-ink plus an LCD layer and are expensive, and the real color e-ink where each micro capsule embeds 3 to 5 different inks of different colors. The latest are pretty complex devices, very slow to refresh (hence why they are not used in your e-reader) and also very expensive. But the rendering is way much nicer because it’s real ink that is used to render the colors.
- blacklion 18d agoThey are used in book readers. Amazon Kindle Colorsoft, for example. Or I have android phone with such screen (though, not latest generation). Rather opposite: I never seen consumer products with two-layer displays.
- pjerem 18d agoNope, that's my point, on your kindle, the screen is a Kaleido 3, which is a black&white+lcd layer: https://www.reddit.com/r/eink/comments/1i8e26x/seriously_how_does_kaleido_3_screens_work/ https://www.reddit.com/r/eink/comments/1i8e26x/seriously_how... Vs Spectra (the expensive screen): https://www.eink.com/upload/2023_11_14/3_20231114082849vy2as6Uon0.gif https://www.eink.com/upload/2023_11_14/3_20231114082849vy2as...
- blacklion 17d agoI don't see LCD layer here. Passive color filters, B/W capsules (which reflects or doesn't reflect incoming light, depends on orientation), TFT (thin layer transistors, not LCD — liquid crystal display!) as control to orient capsules. Yes, it is not 4 color capsules as in Spectra, but where is LCD? LCD what is caught my attention (and surprise) in your commentary. But now I see difference, thank you.

- whiskers 18d agoThis project will work with a 7.3" display just as well - they are £79.50! https://shop.pimoroni.com/products/inky-impression?variant=55186435244411 https://shop.pimoroni.com/products/inky-impression?variant=5... Disclaimer: I am the CEO of Pimoroni :-)
- fnands 18d agoYeah, the 4 and 7.3" prices are not bad, the jump to 13 is just large. That being said, the cost per area goes down, so it is also probably fair.
- whiskers 17d agoCost per area is pretty much what drives all display pricing. :-)

- koryk 18d agoI love the inky impression! I am using my 13 inch inky display for my own birdnet - I also posted this in another thread last week https://i.imgur.com/5XbM6bb.png https://i.imgur.com/5XbM6bb.png I also bought 3 more 4 inch ones. Here is the first deployment next to the fish tank - https://i.imgur.com/nj8nKrS.png https://i.imgur.com/nj8nKrS.png - I like this because I can stuff an rtl sdr in that box too, so it picks up nearby radio sensors in addition to BT. Real nice project screen! I usually only refresh the image on the screen every few hours. I love how the image stays even with no power.
