Electronic paper (or e-paper) is a collective name for display technologies that offer paper-like performance - high display clarity and sunlight readability, and all that with very low power consumption (usually ePaper displays do not require any power while the image is not changing).
ePaper displays are found in many devices (most people will associate ePaper displays with e-readers such as Amazon's Kindle). ePaper displays are slowly entering the consumer laptop market.
Some laptop makers are adopting ePaper displays in their designs, to act as secondary screens. In the image above you can see Lenovo's Yoga Book C930, a windows laptop/tablet hybride that sports a 8-inch E Ink display that can serve as a dynamic keyboard, a notepad or an e-reader.
Some laptop designers are exclusively using an ePaper (usually E Ink) display as the main display in the laptop. These devices are usually offered as mobile 'type writers' - to remove distractions and enhance battery life.
