E-ink

Whait is "E-ink" ? E-ink is a kind of display technology. It can show almost the same effect as the real ink on paper which won't make people tired on reading as the other electronic display techonology such as LCD.

How it works? Electronic ink is made up of millions of tiny microcapsules, about the diameter of a human hair. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the viewer. This makes the surface appear white or black at that spot.

Disadvantages Only can show black, white and gray in the screen.(Colorful e-ink have already been invented, however this techlology still can't be put in the market.) Only can show picture and the text. Most products can't be read in the dark.(Kindle has already solved this problem.)
