Objective Introduction What is flexible electronics? Construction of e-paper How the image seen on the e-paper ? Functionality of e-paper The challenges Advantages & Disadvantages Applications Future scenario Conclusion

To understand the electronic flexible display

To reduce the breaking of glass of mobile phones

To reduce the extra weight in your pocket for carryingsmartphones

Electronic paper was first developed in the 1970s

by Nick Sheridon

First electronic paper called Gyricon

E-Paper is portable, re-usable and storage

display device

It works by using E-Ink technology. E-Paper is

of two types i.e., Non-flexible and flexible

Flexible electronics also known as flex circuits,is a technology for assembling electronic circuitsby mounting electronic devices on flexible plasticsubstrates

Organic Light Emitting Diodes (OLEDs) arenormally used instead of a back-light for flexibledisplays.

What is Flexible Electronics?

Flexible Display

Revolutionary material called graphene isused for exciting possibilities Flexi-tech’s.

Super strong and incredibly thin, graphenewill allows us to make flexible componentsthat are practically indestructible and perfectfor use in bendy new gadgets.

It has two different parts

a) Front plane

b) Back plane

To form an E-ink electronicdisplay the ink is printedonto a plastic film that islaminated to a layer ofcircuitry

Electronic Ink is a paper likedisplay used primarily in eBookreaders

E Ink technology works by usingtiny microcapsules

The microcapsules contain bothpositively charged whiteparticles and negatively chargedblack particles.

Initially voltage is applied across twoelectrode plates of the microcapsule

Black particle move to top of microcapsuleand white particle move to bottom ofmicrocapsule where they become visible,making the pixel

It uses microcapsules technology to produce

color display

Every color has some particular voltage levels

The new paper phone is made of

two layers:

a) E-ink display

b) Flexible printed circuit

The user actually chooses the

function by bending the PCB

We have software that collects the

values given by the bend sensor

These gestures are then fed into

a gesture-recognition engine

Rugged

Light weight

Very thin

The ability to curve,flex,roll,fold

Portability

Low power

Non-breakable

Customer satisfaction and good profit margins

Commercialization of flexible display.

New plastic materials are needed to be

substituted for glass.

Lower cost in the future

Light weight & flexible

Wider viewing angles &

improved brightness

Better power efficiency

Portability & wearable

UV sensitivity

Less Lifetime

Expensive Manufacturing

Susceptible to water

Difficult to read in low

lighting conditions

Digital ID Tags

Digital Price Boards

Books, News Papers and

Magazines

Mobile phones and

gadgets with flexible display

units

APPLICATIONS

It could change the way you

receive daily news paper

Textbooks could be digitized on

E-Paper

More advanced wireless

capabilities

The technology that is about to become commercial reality.

Flexible displays can be bent without being damaged, makingit possible to create products that are ultra-thin, almostunbreakable and flexible.

The potential for this technology can be considerable as theultimate goal to produce cheap mass-produced digital devicesthat can be rolled up like paper. We believe the introduction offlexible display will change the industry landscape.
