Black and White Electronic Ink is based on a series
of fluid-packed microcapsules , one for each screen 
pixel , which contain tiny balls coloured black and 
white and charged negative and positive respec-
tively . By changing the charge underneath the 
capsules the balls can be made to sink , or float , 
with shades of grey achieved by mixing black and 
white areas within a single capsule.
3 - Pigment Electronic Ink is composed of millions of microcups , and each microcup contains black,white and red, or black, white and yellow charged particles which are suspending in a clearfluid . When a positive or negative electric field is applied , corre- sponding particles move to the top of the microcup where they become visible as red or yellow on the surface.
4-Pigment Electronic Ink is composed of millions of microcups, and each microcup contains positively charged red and black particles and negatively charged yellow and white particles. When a nega- tive electric field is applied , red particles move to the top of the microcup. Black particles move to the top by division of positive electric field.
