seminar ppt useful for students

1. Electronic Ink
(our next generation for text)
name
Fifth semester electronics engineering
Roll no:
On 14th July
college

2. YESTERDAY
• People used surrounding material as
display
• Only wealthy people use silk display
• Chinese invented paper on 105 AD

3. Paper display
• Long period paper used as display
• Ink used to made text on it
• Lost popularity due to disadvantages
1. Cannot reprint
2. Difficult to carry
3. Reuse possible after recycle

4. Scientists are now close to
developing a revolutionary technology
that could replace paper, called
electronic ink!

5. E- INK
COMPONENTS
• Millions of tiny microcapsules or
cavities
• An ink or oily substance filling the
microcapsules or cavities
• Pigmented chips or balls with a
negative charge floating inside the
microcapsule

6. What is Electronic Ink?
• Worked on the principle
electrophoresis
• Two types of process
• Charged pigment chips or balls
• Worked by applying electronic
potential

7. How does it actually work?
• E-ink cover entire page
• Separated by cells as a graph paper
• Tiny microcapsules include fluid and
charged particles
• Apply desired charge for desired
change

8. What does all that mean?
• Negatively charged black particles
• Positively charged white particles
• Contain fluid helps to movement of
pigment chips

9. If you were to take
thousands of these
beach balls and lay
them out on a field, and
make the ping-pong
balls move between the
top and bottom of the
beach balls, you could
make the field change
color. That's the
principle behind
electronic ink.

10. In reality, these microcapsules are only 100
microns wide, and roughly 100,000 microcapsules
can fit into a square inch of paper. In each of
those microcapsules there are hundreds of
smaller pigmented chips. In prototypes, E Ink is
currently working with white chips and blue ink,
but it is working to develop other color inks that
could lead to multicolor displays.

11. WORKS
• When +ve voltage
applied at top the
-ve charged black
chips attracted to
upside and text
become visible
• Text disappears
when voltage
reverse

12. Like reading the
newspaper?
• Change the way of reading of
newspaper
• Can read a paper in a page by single
click
• Reduce paper wastage
• Save nature

13. E-INK V/S ORDINARY INK
• Superior Look
• Versatile
• Paper-Like
Readability
• Ultra-Low Power
Consumption
• Reduced eyestrain
• Lightweight
• Flexibility
• Scaleable
• Low Risk
Manufacturing

14. Positives
• Save paper
• Save space
• Less to carry
• Increase
technological skills
• Clean hands
(newspaper)
Negatives
• Eliminate jobs
• Malfunctions
• Loss of data
• Lack of
technological
knowledge
• Expensive

15. APPLICATIONS
• Electronic paper
watch
• Paper- thin digital
clock
• E-News paper
• Mobile display
solutions
• Signage
