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.
