Rohit Egade presented on e-paper technology. E-paper is also called electronic paper or electronic ink display. It is flexible, portable, and can hold text and images like ordinary paper but uses electronic components. E-paper was first developed in the 1970s and two main technologies are electrophoretic and gyricon. It has a front plane made of e-ink and a back plane of electronic circuits. E-paper has properties like being thin, flexible, requiring no power to hold images, and being readable in sunlight. It can be used in applications like e-readers, watches, mobile phones, and status displays. Advantages include low power use and reading like paper while disadvantages are slow switching speeds

3. INTRODUCTION
 E-Paper is also called Electronic Paper or Electronic ink Display.
 It is flexible, rollable, portable, reusable storage and display unit.
 Electronic paper displays reflect light like ordinary paper.
 It capable of holding text and images.
 Reflective & can be easily read in bright sunlight.
 A digital pen is also used to create handwritten document.

4. 2. HISTORY
 Developed in the 1970’s by Nick Sheridon at Xerox's Palo Alto
Research Center.
Two companies are working on this.
One is at Cambridge in USA.
The other is Xerox at Xerox’s Palo Alto Research Center.

5. 3. CONSTRUCTION
 It has two different parts,
1. Front plane
2. Back plane
 The front plane consist of E-ink.
 The back plane consist of electronic circuit.
 To form an E-ink electronic display the ink is printed on
to a plastic film i.e. laminated to a layer of circuitry.

3. Electrowetting-

9. 07. PROPERTIES
Ultra thin and flexible energy cell.
Eliminates the cost of the battery.
Can be integrated into almost any surface.
Environmentally friendly, no possibility of explosion, burns, or
overheating.

10. 08. REQUIREMENTS FOR E-PAPER
Resolution
Contrast Ratio
Viewing angle
Flexibility
Light weight
Power it should be Bi-stable: Uses zero power to retain a still image.
It should be readable in sunlight, reflectance should be more than 30%.
It should be light weighted as a paper-card.

11. WHERE CAN I USE E-PAPER DISPLAYS
 The most popular application for e-paper displays today is an e-reader.
 Popular readers include Amazon kindle, Sony reader, and the Barnes & Nobel
Nook.
How to connect e-reader with computer or mobile
 By USB
 By Wi-Fi

APPLICATIONS
10.

13. Electronic paper Display Liquid Crystal Display
Wide viewing angle Best image only from one position
Black on paper white Gray on gray
Readable in sunlight Can be difficult to see
Holds image without power drain Required power to hold images
Plastic or glass Glass only
Light Weight Power supply and glass make LCDs
relatively heavy
Thin (~1 mm) Thick (~7 mm)
11.

14. Simple manufacturing process.
Light weight and thin.
No need of ink and paper.
Low power consumption because no light emitting device is used .
More convenient.
12.

15. Very low switching speed.
Imprint of an image may be visible after refreshing parts of the
screen.
 Imprint are known ghost images.
13.

16. An e-device that will consume little power
while also providing high function and color
(video playing and web browsing) while also
featuring good visibility in sunlight.
14.

17. Researches found that in just few years this technology can
replace paper in many situations, leading us to think of a truly
paperless world.
