3. ❖The first E-Paper is developed in 1974’s by
Nicholas K Sheridon at Xerox’s Palo Alto
Research Centre.
❖E-Paper is also called Electronic Paper or
Electronic ink Display.
❖It is a display unit.
❖E-Paper is flexible.
❖E-paper have a wide viewing angle.
❖A digital pen is also used to create handwritten
document.
4. ➢E-Paper is an electronic ink display unit.
➢It reflect light like ordinary paper.
➢It is capable of holding text and images.
➢It is flexible while using plastic materials and
electronics.
➢It is more comfortable to read than conventional
display.
➢A wider viewing angle.
➢It can read directly from sunlight without fading
images.
6. ▶ It has two different parts.
◦ Front plane.
◦ Back plane.
▶ The front plane consist of E-ink.
▶ The back plane consist of electronic circuits.
▶ To form an E-ink electronic display the ink is
printed onto a plastic film that is laminated to a
layer of circuitry.

9. GYRICON
▶ The first Gyricon E-ink developed in 1974s by “Nick
Sheridon” at Xerox.
▶ It based on a thin sheet of flexible plastic containing a
layer of tiny plastic beads each encapsulated in oil and
it rotate freely.
▶ Each hemisphere of a bead has different colour and
different electric charge.
▶ Electric field is applied the beads are rotate, creat two-
coloured pattern.

11. ▶ This method have some limitations.
1. Low brightness and resolution.
2. Lack of color.
Other form of E-ink with improve propertys
compared to Gyricon is Electrophorestic.
12. Electrophorestic
▶ Electrophorestic frontplane consist of millions of
micro capsules.
▶ Each approximately 100 microns in dia.
▶ Each micro capsule is filled with a clear fluid
containing positivaly charged white particle and
black particle.
13. ▶ How Electronic Ink Works:- Basically, this form of
e-paper is created by sandwiching millions of tiny
plastic wells between two sheets of flexible plastic.
▶ Each well contains both white and black particles,
suspended within a clear fluid.
▶ The key to this technology is that the white and
black particles have opposite charges, so when an
electric voltage is applied to individual wells --
through circuitry embedded underneath -- the
black and white particles can be separated to
opposite sides.
14. ▶ In this way, the face-up side of each well can be
set to appear either as black or white as seen
through the top layer of clear plastic.
▶ Each well functions as a separate pixel on the E
ink display..
▶ The disadvantage of this technology is it take
time for the particle to move from one side to
another.
Drawing a new text or image is too slow and creat
a flicker.

16. ▶ Ultra-thin and flexible energy cell.
▶ Eliminates the cost of the battery,weight and
volume of the battery holder.
▶ Can be made into almost any shape.
▶ Can be integrated on almost any surface.
17. ▶ Low cost and simple to produce, using printing
process.
▶ Environmentally friendly, non-caustic, no
possibility of explosion, burns, or overheating.
18. ▶ Paper-like Readability.
▶ Ultra-Low Power Consumption.
▶ Clarity.
▶ Reduced Eyestrain.
▶ Mobile Display Solution.
▶ Hypertext.
▶ Multimedia Information.
▶ Include Graphics.
▶ Inexpensive.
19. ▶ Very low switching speed
▶ Electrochemical complexity
▶ Slow response to change
▶ Too slow for video
▶ Problems in extremes temperatures,humidity
