What is E ink???E Ink is the creator of electrophoretic or electronic ink.

Electronic ink is actually a straightforward fusion of chemistry, physics and electronics.

It's so much like paper.

20/02/2015


History Research started at the MIT Media Lab in 1996.

Joseph Jacobson and Barrett Comiskey • invented E ink in 1996.

On June 1, 2009, E Ink Corp. Purchased technology by• one of its primary business partners, Prime View Int'l Co. Ltd

WORKING A millions of cell particles are present in a display of any

device E-ink is made up of millions of tiny microcapsules that are

suspended in liquid placed within a film-like layer. The liquid is present in b/w both the pigments(black and

white) Applying a –ve electrical field causes then the white pigments

(+ve) to come to the surface As same as when a +ve electric field causes then the black

pigments (-ve) will come to the surface Applying different fields at various parts of a screen, E Ink can

produce a text display

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. Back plane is made up of organic thin film transistor arrays which

provide voltage needed by the E-Paper. To form an E-ink electronic display the ink is printed onto a plastic

film that is laminated to a layer of circuitry.

The front plane consist of E-ink.

E-ink is made up of millions of tiny microcapsules.

Microcapsules have diameter of the order of 100 microns.

Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid .

When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the viewer. This makes the surface appear white or black at that spot.

Electrophoretic display

Technologies proposed so far for e-paper:

20/02/2015


Each E-ink capsule contains an oily solution containing black dye (the electronic ink), with numerous white titanium dioxide particles suspended within these capsules are dispersed in a hydrocarbon oil in which dark-colored dye and charging agents are also added. Capsule diameter is 40 micrometer.

Gap between the two conducting plates is of the order of 100 micrometers and the mixture is placed between these plates.When a voltage is applied across the two plates, the particles will migrate electrophoretically to the plate bearing the opposite charge from that on the particles.

Electrophoretic display

20/02/2015


When the particles are located at the front (viewing) side of the display, it appears white, because light is scattered back to the viewer by the high refractive -index titania particles.

When the particles are located at the rear side of the display, it appears dark, because the incident light is absorbed by the colored dye.

Applications Wristwatches e-Book readereg: Amazon kindle.

Electronic Shelf LabelIn a large department store or supermarket, e-paper can be used for labeling the shelves and price tagging.

Electronic Billboards Status displays Digital Photo Frames Mobile phones E-Newspaper Time Table at Stations

Applications

E Readers

E Ink Active Matrix displays deliver the best reading experience with the highest contrast and longest battery life for eReaders.

Indicators

• E Ink Segmented displays enable engineers and designers to add high contrast displays where power and space limitations have made it impossible.

20/02/2015


Applications

Watches

It inspire innovative designs and shapes using the lowest power requirements and added durability.

Keypads

• E Ink Segmented displays make it possible to offer breakthrough designs such as dynamic keypads.

Future

• Education

E ink display platforms inspire innovativedesigns that bringclassrooms to life.20/02/2015


ConclusionIt uses electrophoretic technology.Invented by Joseph Jacobson and Barrett Comiskey • in MIT Media Lab in 1996. Objects are displayed on the different moves of pigments. It is being used in mobile phones, watches, indicators etc. E ink having some disadvantages but advantages are more

important and useful. Having a broad future.
