Ultra-Low Power E-Paper Displays


E-paper, also known as electronic paper or electronic ink display, has a paper-like high contrast appearance and an Ultra-low power consumption and effectively mimic the appearance of ordinary ink on paper.

The display is an electronic replacement for traditional paper that we can use for reading things like books, magazines and more. E-Paper, much like real paper, will only reflect light (though newer devices may also feature a back-light to improve readability), so uses much less power than traditional LCDs.

Second is the unique way that E-Paper displays things on the screen. Traditional LCD displays have three colours per pixel – red, green and blue (RGB) – and will light up a combination of these across the entire display to show pictures and video in the correct colour. E-Paper displays have so far only been available in black and white, and they work in a simple way.

By default, it will show just a blank white page, and then when a charge is applied to the pixel, a black ink will rise to the front of the display to turn it black. By doing this across the display, it can display text and simple graphics very easily. Once the pixel colour is swapped, it doesn’t require a charge to stay that way, you only need power to change pages. Therefore, battery life for devices such as a Kindle Paperwhite is advertised as being able to last for weeks.
