E-Paper is a display technology that simulates the look of ink on paper. Unlike traditional displays, E-Paper reflects light, just like regular paper, and can store text and images indefinitely, even without power.

As a result, E-Paper displays and Raspberry Pi are a perfect match because they use very little power while still providing a display for your project.

The display does not require any power to keep the image and will remain 'ON' for many days without a power connection before gradually fading. 

It is, of course, daylight readable and has a high contrast ratio. E-Paper Display (EPD) boasts many edges compared with LCD

The E-Paper displays are available in four sizes- 2.9", 4.2", 5.83", and 7.5".
