This document discusses the development of transparent cellphone technology. It provides details on Polytron Technologies' prototype of a transparent multi-touch display phone using switchable glass technology. The phone appears white and cloudy when powered off but displays images when turned on as liquid crystal molecules realign. Challenges remain around fully integrating batteries and other components. Transparent electronics could enable new applications like see-through displays and help consolidate devices in small spaces. Significant research continues toward developing high-performance transparent materials and improving device performance.

2.  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......!!!!

3.  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.

5.  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 .

7.  “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.

9.  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.

10.  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 .

11.  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 .

13. 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’ .

14.  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.

16.  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

17.  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.

MORE SPACIOUS BY
ALLOWING
ELECTRONIC DEVICES TO
BE CONSOLIDATED AND
STACKED IN SMALL SPACES.
**THIS TECHNOLOGY COULD
ENABLE THE WINDOWS OR
MIRRORS IN OUR HOMES
TO BE USED AS
COMPUTER MONITORS AND
TELEVISION SCREENS.

21. 3 GOALS TO MOVE AHEAD
the first scientific goal of this technology must be to discover, understa
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.

23. A NEW REVOLUTION

24. 24
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…!!!

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.

27. 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…!!!

29. FUTURE GADGETS

30. 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.

32. Boom in electronic gadgets
