Rather opposite: I never seen consumer products with two-layer displays.
- pjerem 11d 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 10d 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.
