For those of you, who are not familiar with this type of displays yet, we´l mention, that it´s a so called electrophoretic display, i.e. Display containing white particles in microcapsules dispersed in a thin layer of a dark high-viscosity liquid. These particles can be moved or turned by a short voltage impulse, what will cause a given pixel to appear as white. Similarly an impulse of a reverse polarity will cause a given pixel to appear as black or it can also be grey (usually 4 shades of grey). High viscosity of a liquid causes that microparticles remain their position practically forever (years). That means, that this type of displays only need an electric energy to change a displayed content (!). In other words it´s an ideal display for battery powered devices. From some point of view is the behavior of ePaper display similar to bistable (latching) relays. A display is reflexive, i.e. doesn´t require backlight but for a good legibility at least a low ambient light is necessary. It´s advantageous that the display is easily readable even on a direct sunlight. A charm of ePaper display is also in the fact, that a displayed content is really similar to that sketched/ written on a paper.
