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.

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.

Light weight and durable. Low power consumption.

.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

GYRICON - 1974 The first Gyricon E ink developed in s

“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

.This method have some limitations1. L .ow brightness and resolution2. .Lack of color

- Other form of E ink with improve propertys .compared to Gyricon is Electrophorestic

Electrophorestic Electrophorestic frontplane consist of

.millions of micro capsules 100 .Each approximately microns in dia Each micro capsule is filled with a clear

fluid containing positivaly charged white .particle and black particle

A negative electric field is applied the , white particles move to the top causing

.the area to appear as a white dot When a positive electric field is applied the

black particle migrate to the top and white .particle move to bottom

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

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.

Low cost and simple to produce, using printing process.

Environmentally friendly, non-caustic, no possibility of explosion, burns, or overheating.

Researches found that in

just few years this technology

can replace paper in many situations, leading us to think of a truly paperless world.
