The display also does not show any burn-in tendency when the same image is displayed for extended periods. In addition to high contrast and virtually no viewing angle dependence, this type of display has several other advantages: electricity only flows when the displayed information needs to be changed, the image remains without any external electrical input so overall the energy consumption is very low.
Each bead represents a pixel and each contains a positively charged white pigment particle and a negatively charged black pigment particle. Charged beads drift in a fluid and are drawn to the viewing surface when a voltage is applied. The technology on which these screens rely is called electrophoretic displays (keyword: eInk / ePaper), electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The display readability is excellent even in bright sun, perfect for chilling out on the beach!
I’m an avid reader so it’s useful to have all the books I’m reading on the one device rather than lugging a pile of books around with me.
Since they were first introduced I’ve been a big fan of e-book devices, I find them easy to use and like the display crispness along with the added functionality provided by menu options.
