I want to create a project which involves reading of values of pixels on e ink display. I know there are e ink with touchscreen inputs but I was wondering whether it is possible to use only an e ink display and strong magnet ( in a pen like structure) to alter the black and white at a particular pixel and then read whether the pixel holds a black or white value. Is this even possible? I tried to search on the internet but didn't find much.

  • \$\begingroup\$ Is this even possible? I suggest that you research how an E ink display works, then think how that would work with your idea. You will need to be able to explain how your idea would work, so not explaining what it does but how it does that. \$\endgroup\$ – Bimpelrekkie Jun 25 '19 at 14:15
  • \$\begingroup\$ I read how an E ink display works..and so far I have concluded that this idea wouldn't work. But I am a beginner in electronics so I needed an experts opinion on this. Thank you so much for your help though.. \$\endgroup\$ – infottie Jun 25 '19 at 14:17

No, it is not possible. E-ink displays are not based on magnetism at all. And it isn't possible to use the electrodes to determine the current state of a pixel anyway.
