Image Analysis and Computer Vision

Until now, the only way to get "full" color from an EPD -- at least the only way that E Ink has shown us -- is placing a matrix color filter in front of the monochrome display. E Ink showed the way forward a few years ago with a black, white, and red display, which managed to control particles of three different colors using differences in mobility and a cleverly designed controlling waveform. At Display Week 2016, E Ink introduced an impressive expansion of this approach, in which particles of four different colors are included within each microcapsule, given different mobilities through different sizing, and driven with a pulsed controlling wave movement that permits the creation of thousands of colors, as explained by E Ink's Giovanni Mancini.     The resulting display showed impressively bright and saturated colors and drew crowds.  When a new image was written, the display would flash several times.  It took about 10 seconds for a new image to build...

Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. E Ink Corporation further describes their electronic ink technology as a type of display made of millions of tiny and transparent microcapsules—measuring about the diameter of a human hair. Each microcapsule represents a pixel and each contains a positively charged white pigment particle and a negatively charged black pigment particle. Upon the application of positive or negative electric, corresponding particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white or black at that spot. Advantages: 1) Lower Power Consumption: Note that this display technology is a bistable display. This means that the image on an electrophoretic display screen is retained even when all power sources are removed. The display is only consuming power whenever the displayed image changes. 2) Refl...
