In today’s article, we will talk about the E-ink display commonly used in e-book readers such as the Kindle and Kobo. Initial research on e-ink began in 1996 at MIT’s Media Lab. How it works. E-ink display technology uses tiny microcapsules that contain black and white particles. A negative electrical field causes white particles to appear on the surface, while a positive electrical field causes black particles to appear. It means adjusting the positive and negative electrical fields as needed and displaying the words.
The advantages of e-ink display are: Unlike LCD and AMOLED, it does not have backlit, so the battery is very durable. Most e-readers on the regular market can last from 2 weeks to 1 month on a single charge.
