Electronic Ink Promises To Save A Tree

"E Ink's displays feature a layer of electrophoretic liquid sandwiched between a pair of flexible electrodes. Millions of microcapsules, containing a mixture of dye and pigment, are suspended in the liquid. Driven by a thin-film transistor (TFT) array, the light or dark appearance of each pixel can be switched by altering the polarity of the electrode. Electronic paper gets high resolution.


An electronic book would have to be easy to read and at 160 pixels per inch, this technology should be a better experience than reading from a 72 pixel per inch monitor?
