The first Transparent transistors were

reported in 2003 and display

Conventional wisdoms dictates that we will

have to wait until between 2013 and 2023 to

purchase transparent related merchandise.

We contend that transparent technology is

technology-in-a-hurry......!!!!

Its a question that’s been circulating for

years, thanks to film like Minority Report and

Iron Man 2 that sparks dream of diaphanous

mobile future, and more than decade

later,its one that’s still without an answer.

Sony Ericsson’s Xperia pureness fell that

when it hit in the market in 2009.

Now , Taiwan based Polytron technologies is

trying to revive the dream , with a transparent

multi touch display that its begun marketing to

OEMs .

As mobile Geeks reports, the key to polytrons

prototype is its so called Switchable Glass

technology-a conductive OLED that uses liquid

crystal molecules to display images.

When the phone is powered off, these molecules

from a white cloudy composition , but once

activated with electric current , they realign to

form texts , icons , or other imagery .

“IT WILL HAPPEN NEAR THE END OF

2013.TRUST ME.”

In its current form , the device still is not

totally transparent.

Most glaring is the SD card , inserted on the

bottom left side of the phone , along side

the SIM card.

The microphone , camera , and batteries are

also visible though polytron plans to hide this

with a darker glass cover once it goes to

production.

In an interview with The Verge , Polytron

general manager Sam yu acknowledged that

the company still working on integrating a

smaller , less conspicuous lithium-ion battery

.

Transparent lithium technology has been in

development for some time now , but for the

movement , yu’s prototype runs on two small

(and very visible) batteries.

Sam yu told “ It will happen near the end of 2013 “.

The looming question , though , is whether or not the market even wants a translucent device.

Companies like Samsung , LG , and others have been touting larger transparent displays for years now .

In its finished state , the phone will feature

dual sided multiple displays (Front and

back), raising new possibilities for OS and UI

design.

At this time , however , the display still very

much in development .

The prototype features no software or

operating system , which makes it difficult to

visualize in practice .

The material used in transparent

cellphone:- The semiconductor, the

electric contacts, and the dielectric

layers,

must now be invisible –

Touch display

panels, solar cells,

flat panel displays,

heaters , ‘smart

windows’ .

Researchers at Oregon State University and Hewlett Packard have reported

their first example of an entirely new class of materials which could be used to

make transparent transistors that are inexpensive, stable, and environmentally

benign.

Significant advances in the emerging

science of transparent electronics, creating

transparent "p-type" semiconductors that

have more than 200 times the conductivity

of the best materials available for that

purpose a few years ago.

This basic research is opening the door to

new types of electronic circuits that, when

deposited onto glass, are literally invisible.

OLED is nothing but organic light-emitting

diode emissive electroluminescent layer is

film of organic compound which emits light

in response to electric current.

This layer of organic is semiconductor is

situated between two electrode typically one

of this is transperent.

OLED’s are used to create digital displays in

various devices like mobiles, television,

monitors of computer

OLED’s based on

small molecules and

those employing

polymers.

Adding mobile ions

to an OLED’s creates

light emitting

electrochemical cell

which is different

mode of operation.

3 GOALS TO MOVE AHEAD

the first scientific goal of this technology must be to discover, understand

and implement transparent high-performance electronic materials.

The second goal is their implementation and evaluation in transistor and

circuit structures.

The third goal relates to achieving application-specific properties since

transistor performance and materials property

requirements vary, depending on the final product device specifications.

A NEW REVOLUTION

APPLICATIONS OF TRANSPARENT CELLPHONE

Transparent circuits will have

unprecedented applications in flat panel

displays and other electronic devices,

such as see through display or novel

display structures.

They have been widely used in a

variety of applications like:

1. Antistatic coatings

2. Touch display panels

3. Solar cells,

4. Flat panel displays

5. Heaters

6. Defrosters

7. Optical coatings.

and many more….

MARKET OF TRANSPARENT technology

There are four critical aspects of “transparency” that the design and marketing of transparent

electronics products needs to focus on for it to become a serious revenue earner. These

factors are:

• Aesthetics

• Integration

• Improved economics

• Aspects of transparent materials that are not directly related to transparency.

.The transparent devices in the market have

two challenges to overcome in order to capture

the market. They are:

• Too cool to succeed

• Current apps for transparent electronics are

quite primitive.

These are the major distraction in the path of

these invisible devices…!!!

26

Future Scope In the field of solar cells, although

much progress has been made in

developing new materials and

devices for high performance

transparent solar cells, there is still

plenty of opportunity to study and

improve device performance and

fabrication techniques compared with

the nontransparent solar cell devices.

It is likely that new scientific

discoveries and technological

advances will continue to cross

fertilize each other for the foreseeable

future.

The team are also exploring

using the resistance

properties of their material

not just for use in memory

but also as a computer

processor . This versatility

will someday replace

memory and central

processing units(CPUs)with a

single chip that can perform

both functions.

FUTURE SCOPE

much progress has been made in developing new materials and devices for

high performance transparent solar cells, there is still plenty of opportunity

to study and improve device performance and fabrication techniques

compared with the nontransparent solar cell devices.

CONCLUSION

Oxides represent a relatively new class

of semiconductor materials applied to

active devices, such as TFTs, SWNT

transistors.

The combination of high field effect

mobility and low processing temperature

for oxide semiconductors makes them

attractive for high performance electronics

on flexible plastic substrates.

Let us hope that we are soon going to

see transparent technology being

implemented in our lives…!!!

FUTURE GADGETS

What we see in science fiction movies are going to be a real working

technology and it is not very far , Competition in the world of technology

brings us suprising stuffs that we once dreamed of.

Boom in electronic gadgets

That’s all about

Transparent

Cellphone…!!!

Thank you and

queries…!!!
