3. Introduction
 E-paper is also called as Electronic-paper
or electronic ink are display technologies
that mimic the appearance of
ordinary ink on paper.

4. Earlier Overview
 The first e-paper was developed in 1974’s by
“Nicholas K Sheridon” at Xerox’s Palo Alto Research
centre.
 E-paper has wide viewing angle.
 It is flexible.

5. Construction of E-paper
 It has two different parts.
 Front Plane
 Back Plane
 The front plane consits of E-ink
 The back plane consits of electronic circuits.
 The form an e-ink electronic display the ink is printed
onto a plastic film that is laminated to a layer of
circuitry.

7. Technology used

8. Gyricon
 The first electronic paper, called Gyricon, consisted of
polyethylene spheres between 75 and 106 micrometers
across.
 The spheres are embedded in a transparent silicone
sheet,with each sphere suspended in a bubble of oil so
that they can rotate freely.

10. Electrophoretic:
 This technique is given by making some changes in
gyricon method.
 Electrophoretic front plane consits of millons of micro
capsules.
Each micro capsule is filled with a clear fluid
containing positively charged white and black
particles.

12. Electrowetting
 It is used to display colored images
 Controls shape of water/oil interface on application of
voltage or else remain same.
 Features
 Fastswitching
 Low voltage
 Vedio support

13. Applications
 Wrist Watches
 Mobile phones
 e-books
 Electronic shelf labels
 News papers

14. Advantages
 Paper like Readability
 Reduce eye strain
 Inexpensive
 Thin and light weight
 Twistable
 Easy to download information
 Clarity

15. Disadvantages
 Very low Switching speed
 Low refreshing rate.
 Ghoasting.

16. Conclusion
 Researchers found that in just few years this
technology can replace paper in many
situations,leading us think of a truely paper less
world.
