E-Ink means Electronic Ink.
E Ink technology is generally used in electronic display, mobile devices, smartphones, smart cards and watches etc. E Ink is primarily used in digital e-readers. Most digital books use gray-scale and rarely use color.

E Ink VS E-Paper:
Before we continue, it’s important that we distinguish between E-Ink and E-Paper. The two may sound the same, but there are some nuances that you need to be aware of.
E-Paper is any type of display which emulates the appearance of paper, and there are a few different technologies that come under this umbrella. As a rule, e-Paper displays are reflective rather than emissive, which means that they rely on external light sources rather than emitting their own light (like LCD or OLED displays).
E Ink vs. Paper: here are some of the obvious savings and advantages:
- Real time information
- Easy to update
- Little to no maintenance
- Environmentally friendly
Applications:
- E-book readers
- E-Watches
- Displays embedded in smart cards
- Mobile phones
- Electronic shelf labels
- Transport timetables
- Digital signage
- Others (Digital photo frame, information board, keyboard)
