    eInk
  • Capsules Top screen layer Bottom screen layer
  • There are millions of capsules between the two layers
  • Each capsule is about 5 microns wide. A micron is one millionth of a meter.
  • How BIG is a micron? Strand of hair 20-180 microns wide Red blood cell 8 microns wide
  • How do the capsules work? Filled with fluid Each capsule contains thousands of smaller black and white particles Top screen layer Bottom screen layer
  • How do the capsules work? All of the particles carry a magnetic charge The white particles have a positive charge The black particles have a negative charge
  • But how does this make letters appear on the screen?!
  • Back to the layers of the screen…
  • Top layer Capsules Bottom layer Electrodes Thousands of electrodes under the screen emit positive and negative electrical charges.
  • Top layer Capsules Bottom layer Electrodes When a negative charge is emitted, the negatively charged black particles are repelled and are pushed to the top of the capsule. Negative charge emitted
  • Top layer Capsules Bottom layer Electrodes When a positive charge is emitted, the positively charged white particles are repelled and are pushed to the top of the capsule. Positive charge emitted
  • Thousands of electrodes and millions of microcapsules work together to create letters and images on your eReader screen.
    • Slide power switch on top of Kindle to turn on
