INTRODUCTION E-Paper is also called Electronic Paper or Electronic

ink Display.

The first E-Paper was developed in 1974’s by “Nicholas

K Sheridon” at Xerox’s Palo Alto Research Centre.

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.

-CONSTRUCTION OF E PAPER

.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

BACK PLANE LAYOUT

GYRICON The first Gyricon developed in 1974 by

“Nickolas K ” Sheridon at Xerox Palo Alto Research Centre.

It is based on a thin sheet of flexible plastic containing a layer of tiny plastic beads each encapsulated in oil and it .rotate freely

LIMITATIONS L .ow brightness and resolution .Lack of color - Other form of E ink with improve

propertie s compared to Gyricon is.Electrophoretic

Electrophoretic Electrophoretic frontplane consist of

.millions of micro capsules Each micro capsule is filled with a clear

fluid containing positive ly charged .white particle and black particle

The disadvantage of this technology is it take time for the particle to move

.from one side to anotherElectrowetting It is used to display coloured images.

CHARGED PARTICLE DISTRIBUTION

PROPERTIESUltra-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.Environmentally friendly, non-caustic, no

possibility of explosion, burns, or overheating.

COMPARISON OF E-PAPER & LCD

Electronic Ink 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)

ADVANTAGES• Paper-like Readability• Clarity• Reduced Eyestrain• Include Graphics• Inexpensive

DISADVANTAGES• Very low switching speed• Electrochemical complexity

APPLICATIONS

Electronic Book Electronic Newspaper Mobile display C omputer monitor

CONCLUSION

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