We know from a previous post I posted
that the e-ink screen seems to be affected by sunlight.
So far I've quickly tested using a magnetic screwdriver,and a magnet from the fridge, but the screen does not seem to be affected by that.
At this moment I have no more powerful magnet than those, but if sunlight affects the e-ink, surely a weak magnet should too.
So far there's no evidence that the e-ink screen is magnetic.
I have more the sensation it is a TFT screen stripped of the RGB grid, and backlight.
The basic function of using a polarization filter and a Liquid when adding a voltage the liquid will be like 2 opposing polarization filters, darkening the screen.
This same principle is used in solar powered calculators, and some PDA's,only now there is a white plastic background.
On the other hand, no matter how I tile the screen, the black ink does not appear to be 'floating' above the white screen, as should be with polarization filters.
Makes me wonder, why, if the e-ink screen truly is magnetic, why it is not affected by standard magnets.
I could start experimenting with more powerful speaker magnets,or Neodymium magnets soon,to see if the same applies here.
I have been using Neodymium magnets next to my Kindle screen for some months. They have had absolutely NO effect at all.
You may have a different result, but that's what my experience has been. I have four 1/2 inch by 1/8th inch Neodymium magnets right up close and personal. Hasn't done anything to the screen, or to the memory.
Again .... that is my experience.
