ABSTRACT

E-paper is a revolutionary material that can be used to make next generation electronic

displays. It is portable reusable storage and display medium that look like paper but can be

repeatedly written one thousands of times. These displays make the beginning of a new area

for battery power information applications such as cell phones, pagers, watches and hand-held

computers etc.

Two companies are carrying our pioneering works in the field of development of

electronic ink and both have developed ingenious methods to produce electronic ink. One is

E-ink, a company based at Cambridge, in U.S.A. The other company is Xerox doing research

work at the Xerox's Palo Alto Research Centre. Both technologies being developed

commercially for electronically configurable paper like displays rely on microscopic beads

that change color in response to the charges on nearby electrodes.

To build e-paper, several different technologies exist, some using plastic substrate and

electronics so that the display is flexible. E-paper or electronics ink display technology

designed to mimic the appearance of ordinary ink on paper. Unlike a conventional flat panel

display, which uses a back light to illuminate its pixels, electronic paper reflects light like

ordinary paper and is capable of holding text and images indefinitely without drawing

electricity, while allowing the image to be change later.

Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost.

Research found that in just few years this technology could replace paper in many situations

and leading us ink a truly paperless world.

1. INTRODUCTION

Today's electronic displays have ever more evolved to be more lightweight, efficient

and clear. Yet the importance of the paper has not diminished. We still prefer it to others for a

variety of reasons including its readability, high contrast, convenient handling, minimum

power requirement cost and strain less reading it offers. At the same time, an electronic

display offers us a paperless environment and relieves us from carrying loads of paper for

referring to information when required.

Electronic ink is a pioneering invention that combines all the desired features of a

modern electronic display and the sheer convenience and physical versatility of sheet of

paper. E-paper or electronic paper is sometimes called radio paper or smart paper. Paper

would be perfect except for one obvious thing: printed words can't change. The effort is to

create a dynamic high-resolution electronic display that's thin and flexible enough to become

the next generation of paper.

The technology has been identified and developed is well under way. Within five

years, it is envisioned electronic books that can display volumes of information as easily asflipping a page and permanent newspapers that update themselves daily via wireless

broadcast. They deliver the readability of paper under virtually any condition, without

backlighting. And electronic ink d isplays are persistent without power, drawing current only

when they change, which means batteries can be smaller and last longer.

1.1 History

Electronic paper was first developed in the 1970s by N ick Sheridon at Xeroxs Palo

Alto Research center. The first electronic paper, called Gyricon, consisted of tiny, statically

charged balls that were black on one side and white on the other. The "text" of the paper was

altered by the presence of an electric field, which turned the balls up or down.

In the 1990s another type of e lectronic paper was invented by Joseph Jacobson, who

later co-founded the corporation E Inkwhich formed a partnership with Philips Components

two years later to develop and market the technology

2. TECHNOLOGY USED

2.1 GyriconElectronic paper was first developed in the 1970s by Nick Sheridon at Xerox's Palo

Alto Research Center. The first electronic paper, called Gyricon, consisted of polyethylene

spheres between 75 and 106 micrometers across. Each sphere is a Janus particle composed of

negatively charged black plastic on one side and positively charged white plastic on the

other(each bead is thus a dipole). The spheres are embedded in a transparent silicone sheet,

with each sphere suspended in a bubble of oil so that they can rotate freely. The polarity of

the voltage applied to each pair of electrodes then determines whether the white or black sideis face-up, thus giving the pixel a white or black appearance. At the FPD 2008 exhibition,

Japanese company Soken has demonstrated a wall with electronic wall-paper using this

technology

2.2Electrophoretic

An electrophoretic display forms visible images by rearranging charged pigment particles

using an applied electric field.

In the simplest implementation of an electrophoretic display, titanium

dioxideparticles approximately one micrometer in diameter are dispersed in a hydrocarbon

oil. A dark-colored dye is also added to the oil, along with surfactants and chargingagents that cause the particles to take on an electric charge. This mixture is placed between

two parallel, conductive plates separated by a gap of 10 to 100 micrometers. 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. 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-index titanium 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. If therear electrode is divided into a number of small picture elements (pixels), then an image can

be formed by applying the appropriate voltage to each region of the display to create a pattern

of reflecting and absorbing regions.

Electrophoretic displays are considered prime examples of the electronic paper

category, because of their paper-like appearance and low power consumption.

Electrophoretic displays can be manufactured using the Electronics on Plastic byLaser Release (EPLaR)process developed by Philips Research to enable existing AM-LCD

(Active matrix liquid crystal display) manufacturing plants to create flexible plastic displays.

2.2.1. Electronics on Plastic by Laser Release (EPLaR) :

Electronics on Plastic by Laser Release (EPLaR) is a method for manufacturing

flexible electrophoretic display using conventional AM-LCD manufacturing equipment

avoiding the need to build new factories. The technology can also be used to manufacture

flexible OLED (Organic LED) displays using standard OLED fabrication facilities.

The technology was developed by Philips Research and uses standard display glass as

used in TFT-LCDprocessing plants. It is coated with a layer of polyimide using a

standard spin-coatingprocedure used in the production of AM-LCD displays. This polymide

coating can now have a regular TFT matrix formed on top of it in a standard TFT processing

plant to form the plastic display, which can then be removed using a laser to finish the d isplay

and the glass reused thus lowering the total cost of manufacture.

2.2.2 Development in Electrophoretic Display:

In the 1990s another type of electronic paper was invented by Joseph Jacobson, who

later co-founded the E Ink Corporation which formed a partnership with Philips

Components two years later to develop and market the technology. In 2005, Philips sold the

electronic paper business as well as its related patents to Prime View International. This used

tiny microcapsules filled with electrically charged white particles suspended in colored oil. In

early versions, the underlying circuitry controlled whether the white particles were at the topof the capsule (so it looked white to the viewer) or at the bottom of the capsule (so the viewer

saw the color of the oil). This was essentially a reintroduction of the well-

known electrophoretic display technology, but the use of microcapsules allowed the display

to be used on flexible plastic sheets instead of glass.

Fig-2.2:Basic Scheme of an Electrophoretic Display using color filters

One early version of electronic paper consists of a sheet of very small transparent

capsules, each about 40 micrometers across. Each capsule contains an oily solution

containing black dye (the electronic ink), with numerous white titanium dioxideparticles

suspended within.

The particles are slightly negatively charged, and each one is naturally white.

The microcapsules are held in a layer of liquid polymer, sandwiched between two arrays of

electrodes, the upper of which is made transparent. The two arrays are aligned so that thesheet is divided into pixels, which each pixel corresponding to a pair of electrodes situated

either side of the sheet. The sheet is laminated with transparent plastic for protection,

resulting in an overall thickness of 80 micrometers, or twice that of ordinary paper. The

network of electrodes is connected to display circuitry, which turns the electronic ink 'on' and

'off' at specific pixels by applying a voltage to specific pairs of electrodes. Applying a

negative charge to the surface electrode repels the particles to the bottom of local capsules,

forcing the black dye to the surface and giving the pixel a black appearance. Reversing thevoltage has the opposite effect - the particles are forced from the surface, giving the pixel a

white appearance. A more recent incarnation of this concept requires only one layer of

electrodes beneath the microcapsules.

2.3 Electrowetting

Electro-wetting display (EWD) is based on controlling the shape of a confined

water/oil interface by an applied voltage. With no voltage applied, the (coloured) oil forms aflat film between the water and a hydrophobic (water-repellent), insulating coating of an

electrode, resulting in a coloured pixel.

Fig-2.3: Appearance of pixels seen from transparent electrode layer
http://en.wikipedia.org/wiki/Electric_chargehttp://en.wikipedia.org/wiki/Liquidhttp://en.wikipedia.org/wiki/Polymerhttp://en.wikipedia.org/wiki/Polymerhttp://en.wikipedia.org/wiki/Liquidhttp://en.wikipedia.org/wiki/Electric_charge


12/25



When a voltage is applied between the electrode and the water, the interfacial tension

between the water and the coating changes. As a result the stacked state is no longer stable,

causing the water to move the oil aside.

This results in a partly transparent pixel, or, in case a reflective white surface is used

under the switchable element, a white pixel. Because of the small size of the p ixel, the user

only experiences the average reflection, which means that a high-brightness, high-contrast

switchable element is obtained, which forms the basis of the reflective display.

Displays based on electro-wetting have several attractive features. The switching

between white and coloured reflection is fast enough to display video content.

It is a low-power and low-voltage technology, and displays based on the effect can be

made flat and thin. The reflectivity and contrast are better or equal to those of other reflective

display types and are approaching those of paper. In addition, the technology offers a unique

path toward high-brightness full-colour displays, leading to displays that are four times

brighter than reflective LCDs and twice as bright as other emerging technologies.

Instead of using red, green and blue (RGB) filters or alternating segments of the threeprimary colours, which effectively result in only one third of the display reflecting light in the

desired colour, electro-wetting allows for a system in which one sub-pixel is able to switch

two different colours independently. This results in the availability of two thirds of the

display area to reflect light in any desired colour. This is achieved by building up a pixel with

a stack of two independently controllable coloured oil films plus a colour filter.

2.4 Electrofluidic

Electrofluidic displays are a variation of an electrowetting display. Electrofluidic

displays place an aqueous pigment dispersion inside a tiny reservoir. The reservoir comprises


13/25



reservoir. As reported in the May 2009 Issue of Nature Photonics, the technology can

potentially provide >85% white state reflectance for electronic paper.

3. KEY BENEFITS

E-Paper has numerous benefits. The reader does not need to get used to a new format

- reading an E-Paper equals reading a printed newspaper. However, E-Paper guarantees

independency regarding room and time. E-Paper can be read everywhere in the world, at

every hour, and since digital editions can also be received on PDAs and smart phones,

mobility is almost limitless. Additionally, E-Paper saves resources. On the one hand, paper

and space are saved - because E-Paper does not pile up anywhere - on the other hand,

valuable time is saved. Since the complete pages are displayed on the PC monitor, one

instantly gets an overview over all headlines and thus gets to the relevant articles a lot fasterUnlike conventional LCD's and other kinds of reflective displays, an electronic ink

display is exceptionally bright and is ready viewable under both bright and dim lighting

conditions. To be more assertive we could compare electronic ink display with the latest

liquid crystal displays.

Table 3.1: Comparison of E-ink & LCD

15/25



3.1 Paper-like Readability

Paper is easily readable over wide variations in lighting conditions and viewing angle.

E Ink's electronic ink technology approaches printed paper in performance by incorporating

the same coloring pigments often used to make paper white and ink black.

When reading text, both reflectance and contrast are important factors in determining the

readability of a display. In fact, the contrast of E Ink is nearly twice that of printed

newspaper. As can be seen from its high reflectance and contrast the E Ink display is much

more readable than LCD.

The bright paper-white background of electronic ink eliminates the need for a backlight ismost conditions.

3.2 Ultra-Low Power Consumption

Electronic ink displays offer greatly reduced power consumption. Lower power

consumption translates to longer battery life, and perhaps more importantly, the ability to use

smaller batteries in electronic ink devices- reducing device weight and cost. The reason forthe reduced power consumption offered by electronic ink displays is two-fold: (1) they are

completely reflective requiring no backlight and (2) they are inherently bi-stable for extended

periods of time. Once an image is written on an electronic ink display, it will be retained

without additional power input until the next image is written. Hence the power consumption

of an electronic ink display will ultimately depend upon the frequency at which the displayed

image is changed. However, in both cases, a reduction in power consumption by several

orders of magnitude can be achieved by using electronic ink with its bi-stable imaging.

3.3 Thin, Light Form Factor

An electronic ink display module is thinner, lighter weight, and more robust than

conventional LCD's. These benefits are especially important in smart handheld applications

where portability is paramount. First generation, electronic ink displays will be but by

laminating electronic ink to a conventional glass TFT substrate In addition, no polarizes are

required for electronic ink displays. The resulting electronic ink display cell is also about half


16/25



that of a typical LCD cell. Elimination of the glass top sheet means that displays made with

an electronic ink display module should be inherently more robust.

3.4 The Ultimate Mobile Display Solution

Paper-like viewing characteristics and appearance, combined with ultra-low power

consumption and thin light form factors, make E ink's electronic ink display material the ideal

technology solution for information intensive, handheld devices such as PDAs, mobile

phones and e lectronic readers; or any applications requiring a high degree of display

legibility.

3.5 Twistable

Electronic Paper is made using soft plastic containing small particles and fluid. As

there is no hard material, Electronic Paper is highly flexible and it is able to be twisted or

bended into different curvatures. The Electronic Paper can be applied to different shapes o f

products, without being limited to being bonded to flat display panels. The end product

becomes more imaginative in shape and style.

3.6 Simple Manufacturing Process

The manufacturing process is carried out using a roll-to-roll method, similar to

printing paper, by injecting dielectric fluid and charged particles into the layer of capsules,

and then sealing the top layer. The production is performed continuously at high speed. The

Electronic Paper can be produced in a large form and then cut into any desired size and shape

for different application requirements.

4. HIGHLIGHTS OF ELECTRONIC INK

Electronic ink moves information display to a new dynamic level, with dramatic

benefits over traditional media.

Superior Look - Because it's made from the same basic materials as regular ink and

paper, electronic ink retains the superior viewing characteristics of paper, including

high contrast, wide viewing angle, and bright paper-white background.

Versatile - Electronic ink can be printed on almost any surface, from plastic to metal

to paper. And it can be coated over large areas cheaply.

Low Power - Electronic ink is a real power miser. It displays an image even when the

power is turned off and it's even legible in low light reducing the need for a backlight.

This can significantly extend battery life for portable devices.

Scalable - E Ink's electronic ink process is highly scalable, which makes it

competitive against today's older technologies.

5. DISADVANTAGES

Electronic paper technologies have a very low refresh rate comparing with other low-

power display technologies, such as LCD. This prevents producers from implementing

sophisticated interactive applications (using fast moving menus, mouse pointers or scrolling)

like those which are possible on handheld computers. An example of this limitation is that a

document cannot be smoothly zoomed without either extreme blurring during the transition

or a very slow zoom.

Another limitation is that an imprint of an image may be visible after refreshing parts

of the screen. Those imprints are known as "ghost images", and the effect is known as

"ghosting". This effect is reminiscent ofscreen burn-inbut, unlike it, is solved after the

screen is refreshed several times. Turning every pixel white, then black, then white, helps

normalize the contrast of the pixels. This is why several devices with this technology "flash"

the entire screen white and black when loading a new image, in order to prevent ghosting

from happening.

6. APPLICATIONS

Electronic Paper behaves similarly to conventional paper, allowing high readability

under low or high light conditions, and being thin and lightweight and fully pliable. In

addition, Electronic Paper has the advantage of allowing the content to be changed easily at

any time via the Electronic Paper driver IC. Electronic Paper will provide a viable substitute

to paper in certain areas. Some examples of Electronic Paper applications are described

below.

6.1 Electronic Shelf Label

In a large department store or supermarket, there are many price tag labels on the

shelves indicating product price. Whenever there is a change of price information, it is very

tedious to change the price tags individually. By replacing the paper price tag with Electronic

Paper, the price information can be easily updated once the Electronic Paper price tags are

connected via a wireless network.

Fig-6.1: Electronic Paper used in Price Tag Application

The Electronic Paper price tag requires no battery power to maintain display and

prices can be updated using the energy from the RF wave to change the image content.

6.2 Electronic Watch and Clock

Watch and clock designs can become more imaginative using Electronic Paper.

Fig-6.2: Electronic Paper Watch and Bendable Module

For example, a watch using Electronic Paper will allow time and image to be displayed onthe wrist strap of the watch.

6.3 e-Books

In 2004 Sony released Libri EBR-1000EP in Japan, the first e-book reader with an

electronic paper display. In November 2006, the iRex iLiad was ready for the consumer

market. In November 2009 Barnes and Noble launched the Barnes & Noble Nook, based on

the Android operating system.

In late 2007, Amazon began producing and marketing the Amazon Kindle, an e-book

reader with an e-paper display.

6.4 Smart Card Display

Today, many credit cards contain a smart card to store information such as

accumulated credit and money expenses etc. Since Electronic Paper has the advantage of

lower power consumption and is as flexible as the card, it offers a good solution to displaying

this type of information on the card.

6.5 Newspapers

In February 2006, the Flemish daily De Tijd distributed an electronic version of thepaper to select subscribers in a limited marketing study, using a pre-release version of

the iRex iLiad. This was the first recorded application of electronic ink to newspaper

publishing.

In September 2007, the French daily Les chos announced the official launch of an

electronic version of the paper on a subscription basis.

Since January 2008, the Dutch daily NRC Handelsblad is distributed for the iRex

iLiad reader.

6.6 Other Products

E- Ink unveiled its first product using electronic ink- immediate large-area displays- in

1999. These large signs draw only 0.1 watts of power, which means that the same power

required running a single 100-watt light bulb, could power 1,000 immediate signs. E Ink said

that in electronic devices, electronic ink would use 50 to 100 times power than liquid crystaldisplays because electronic ink only needs power when changing its display. Electronic ink

can be printed on any surface, including walls, billboards, product labels and T-shirts.

Homeowners could soon be able to instantly change their digital wallpaper by sending a

signal to the electronic ink painted on their walls.

7. THE FUTURE SCENARIO

The Holy Grail of electronic ink technology is a digital book that can typeset itself

and that readers could leaf through just as if it were made of regular paper. Such a book could

be programmed to display the text from a literary work and once you've finished that tale,

you could automatically replace it by wirelessly downloading the latest book from a

computer database. Xerox had introduced plants to insert a memory device into the spine of

the book, which would allow users to alternate between up to 10 books stored on the device.

Just as electronic ink could radically change the way we read books, it could change the way

you receive your daily newspaper. It could very well bring an end to newspaper delivery, aswe know it. Instead of delivery people tossing the paper from their bike or out their car

window, a new high-tech breed of paper deliverers who simply press a button on their

computer that would simultaneously update thousands of electronic newspapers each

morning. Sure, it would look and feel like your old paper, but you wouldn't have to worry

about the newsprint getting smudged on your fingers, and it would also eliminate the piles of

old newspapers that need recycling. Prior to developing digital books and newspapers E-Ink

will be developing a marketable electronic display screen for cell phones, PDA's, pagers anddigital watches.

8. CONCLUSION

Electronic ink is not intended to diminish or do away with traditional displays. Insteadelectronic ink will initially co-exist with traditional paper and other display technologies. In

the long run, electronic ink may have a multibillion-dollar impact on the publishing industry.

Ultimately electronic ink will permit almost any surface to become a display, bringing

information out of the confines of traditional devices and into the world around us.
