E ink is an electronic paper display invented in 1996 at MIT. It uses microcapsules containing charged black and white pigment particles that are moved to the top or bottom of the capsule by electric fields to display text and images. E ink displays are used in e-readers and other devices because they are bi-stable, require no power to maintain a display, and can be read in direct sunlight. The document discusses the history, working mechanism, applications, advantages like low power consumption, and future uses of e ink technology.

3. E Ink is the creator of
electrophoretic or electronic ink.
Electronic ink is actually a
straightforward fusion of
chemistry, physics and electronics.
It's so much like paper.
What is E ink???

4.  Research started at the MIT Media Lab in 1996.
 Joseph Jacobson and Barrett Comiskey
invented E ink in 1996.
 On June 1, 2009, E Ink Corp. Purchased technology by
one of its primary business partners.
History

5. 1.E Ink Pearl - July 2010

Typesof E ink

6. 1- Upper layer
2- Transparent electrode layer
3- Transparent micro-capsules
4- Positively charged white pigments
Schematic Diagram

7. 7- Negatively charged black pigments
8- Transparent oil
9- Electrode pixel layer
10- Bottom supporting layer
11- Light

8.  A millions of cell particles are present in a display of
any device
 The liquid is present in b/w both the pigments(black
and white)
 Applying a –ve electrical field causes then the white
pigments (+ve) to come to the surface
 As same as when a +ve electric field causes then the
black pigments (-ve) will come to the surface
 Applying different fields at various parts of a
screen, E Ink can produce a text display
WORKING

9.  E Readers
 Indicators
 Watches
 Keypads
 Cell Phones
Applications

10.  Indicators
E Ink Segmented displays
enable engineers and
designers to add high
contrast displays where
power and space limitations
have made it impossible.
 E Readers
E Ink Active Matrix displays
deliver the best reading
experience with the highest
contrast and longest battery
life for eReaders.
Applications

11.  Keypads
E Ink Segmented displays
make it possible to offer
breakthrough designs such
as dynamic keypads.
 Watches
It inspire innovative designs
and shapes using the lowest
power requirements and
added durability.
Applications

12.  Cell Phones
E Ink Segmented displays
make it possible to offer
lowest power solutions
with superior readability
Applications

13.  Bi-stable
Reduces the power consumption
No refreshment
Reflective display
Ambient light from the environment
Better response in sunlight over LCD and LED
display.
Advantages

14.  Very slow zoom
 Ghost images
Disadvantages

15. At Home
On the Go
Education
Future

16.  At Home
Whether cooking
with new recipes
or keeping
track of prescriptions,
E Ink technology has
many uses inside the home.
Future

17.  On the Go
Add high contrast displays
with direct sunlight readability
where power or space limitations
have made it impossible to do
so before.
Future

18. Education
E ink display platforms
inspire innovative
designs that bring
classrooms to life.
Future

19. It uses electrophoretic technology.
Invented by Joseph Jacobson and Barrett Comiskey
in MIT Media Lab in 1996.
 Objects are displayed on the different moves of
pigments.
 It is being used in mobile
phones, watches, indicators etc.
 E ink having some disadvantages but advantages are
more important and useful.
 Having a broad future.
