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-book Reader

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-paper in smart cards
  • 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)
