Electronic Ink 
(our next generation for text) 
name 
Fifth semester electronics engineering 
Roll no: 
On 14th July 
college
YESTERDAY 
• People used surrounding material as 
display 
• Only wealthy people use silk display 
• Chinese invented paper on 105 AD
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
Scientists are now close to 
developing a revolutionary technology 
that could replace paper, called 
electronic ink!
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
What is Electronic Ink? 
• Worked on the principle 
electrophoresis 
• Two types of process 
• Charged pigment chips or balls 
• Worked by applying electronic 
potential
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
What does all that mean? 
• Negatively charged black particles 
• Positively charged white particles 
• Contain fluid helps to movement of 
pigment chips
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.
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.
WORKS 
• When +ve voltage 
applied at top the 
-ve charged black 
chips attracted to 
upside and text 
become visible 
• Text disappears 
when voltage 
reverse
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
E-INK V/S ORDINARY INK 
• Superior Look 
• Versatile 
• Paper-Like 
Readability 
• Ultra-Low Power 
Consumption 
• Reduced eyestrain 
• Lightweight 
• Flexibility 
• Scaleable 
• Low Risk 
Manufacturing
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
APPLICATIONS 
• Electronic paper 
watch 
• Paper- thin digital 
clock 
• E-News paper 
• Mobile display 
solutions 
• Signage
