The positively
charged white particles and negatively charged black particles react to changes in electrical current, moving to the display surface and coloring the surface.
SiPix epaper displays are created by inserting electrically -
charged white particles into a black dielectric fluid within Microcups.
When an electric field is applied (when turning pages, making selections, etc),
the charged white particles move either to the top or the bottom of the fluid, depending on the polarity of the electric field applied.
Each microcapsule contains negatively
charged white particles and positively charged black particles suspended in a clear fluid.
This «ink» consists of thousands of capsules containing positively
charged white particles and negatively charged black ones.
This «ink» consists of thousands of capsules containing positively
charged white particles and negatively charged black ones.
Each of this microcapsule has two particles; a positive
charged white particle and a negative charged black particle, both suspended in a clear fluid.

Some scientists believe that an electrical apocalypse could really occur, in the event of an electromagnetic pulse attack, described in one 2008
white paper as «a high - intensity burst of electromagnetic energy caused by the rapid acceleration of
charged particles.»
The most popular type of e-paper in use today is E Ink's electrophoretic technology, which creates images by moving around
charged white and black
particles floating in a clear fluid.
For those who aren't familiar with how it works, E Ink relies on tiny capsules containing both a clear liquid and black and
white ink
particles, which are electrically
charged.
Building on the work from the 1970s, the display used electric
charge to rotate black and
white ink
particles inside tiny capsules located in the screen.
A clever solution by E Ink ®, for example, solved the black and
white dilemma by introducing a third color, red, which carries the same
charge as the black
particles of the display film, but rises to the surface under different voltage.
Capsules filled with negatively and positively
charged particles color the surface of an electronic paper display black or
white when an electric
charge is applied (Image source: E Ink ®)
By introducing a negative or positive
charge, the black or
white particles inside an EPD that carry a corresponding
charge are moved to the surface of the display, where they create a picture or text.
This is a
particle - based display, which was conceived originally by Isao Ota in the 70s, where
white particles in a dark dye, or oppositely
charged particles in a glass cavity, provided the contrast media.
The
particles inside the capsules come in different colors and with different electric
charges; in the most basic incarnation of an e-paper screen, these
particles will be either black or
white.
Each sphere is a janus
particle composed of negatively
charged black plastic on one side and positively
charged white plastic on the other (each bead is thus a dipole).
The
particles are slightly negatively
charged, and each one is naturally
white.
