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 wearable market, mostly for smartwatches and fitness bands.
