Because the display is made of these particles, there’s no light necessary (which can reduce eye strain while reading), and devices that use e-ink technology have batteries that last for weeks, as opposed to days.

They use e-ink technology - Barrett Comiskey, one of the inventors of e-ink technology, explained it like this to Science Friday: “What you end up with is salt and pepper inside a microcapsule - and a way to separate them with an applied electric field.” In the context of an e-reader display, the black particles become the words, and the white particles make up the rest of the page when the microcapsules are exposed to a charge. You can read Kindle-formatted e-books on your Amazon Kindle or the free Kindle App for smart phones tablets and desktops.
Most e-readers mimic the experience of ink on a page, rather than attempt to revolutionize reading. In the National Endowment of the Arts’ latest Survey of Public Participation in the Arts, 53 percent of adults responded that they read at least one book for pleasure (not for work or school) in the previous year. Despite Brown's prediction, books are still quite popular. Today’s e-readers bear little resemblance to the wacky contraption Brown conceived of - most articles like “a” or “the” would be omitted for clarity, he planned. In 1930, Bob Brown argued that books would soon become obsolete in "The Readies." He proposed a radical solution: a reading machine through which people could enjoy books without a physical copy, an e-reader. It is available in both ad-supported and, for another $20, ad-free models.
The new version still has the 300 ppi display and 8 GB of storage that the previous version had, and access to Amazon’s collection of e-books. Amazon says that this e-reader has a battery life of up to 10 weeks, compared to up to 6 weeks in the last version, and the new version takes 2.5 hours to charge fully with USB-C charging (with a 9W adapter or larger). The new Paperwhite has a larger screen, 6.8 square inches compared to 6 square inches for the previous version, a dark mode and adjustable warm light, IPX8 water resistance and, according to Amazon, 20 percent faster page turns and 10 percent more brightness at the highest setting. You can pre-order all of the new Kindle Paperwhites now - they will ship on Oct. This is Amazon’s first refresh of the Paperwhite since 2018, and it comes off the heels of Amazon’s latest Kindle interface update, which the company says provides an easier-to-use experience with easier screen switching and a redesigned library. Amazon announced the release of three new Kindle Paperwhite e-readers: the Kindle Paperwhite, Kindle Paperwhite Signature and Kindle Paperwhite Kids.
