Smart Paper is a material that looks and feels very much like
thick, glossy paper, but is actually a controllable display surface.
Invented by Nicholas Sheridon
Produced in rolls like conventional
paper.
But unlike regular paper, it is
electrically writeable and erasable.
3
It resembles paper in

Stores/displays an image

Can be viewed in reflective light

Has a wide viewing angle

Flexible

Relatively inexpensive
4
Structure

SmartPaper is actually two sheets of thin mylar plastic sandwiching
millions of tiny polymer beads randomly dispersed in an oily
medium. Each of the beads are free to rotate within their cavities.
Each bead is a hair-like 100 microns in diameter and has a different
color on each half . The hemispheres are also charged differently
(i.e. positive or negative) so that they exhibit an electrical dipole.
5
Working

SmartPaper beads reside in their own cavities within the flexible
sheet of material.

When voltage is applied to the surface of the sheet, the beads rotate
according to the current to present one colored side to the viewer.
6
Working(cont…)

Adhesive forces between each bead and cavity wall require an
electrical threshold be exceeded before it will rotate. This makes an
image electrically "printed" onto the material stable and unchanging
until "erased" by another transmission.

Electrical signals can be applied to the SmartPaper sheets through
fixed surface electrodes or a moving stylus.
7
Working(cont…)

Applying electrical fields to the display surface changes the image
on SmartPaper. A range of techniques will achieve this result.

In the least expensive option, the back plane contains several
possible images or preprogrammed text and digit messages .

Which image or message is displayed can be controlled by either
programming the sign to display a fixed sequence or a dynamically
changeable sequence using special software and a wireless
network.

Types
There are two versions of Smart Paper:
Normal
Advanced.
10
Normal Smart Paper

cannot change very quickly.

Not suitable for video applications.

The resolution is equal to that of a 20th century newspaper.

Has only very crude sensors to detect stylus movements
11
Advanced Smart Paper

Can change so quickly.

Suitable for video application.

Resolution is like that of a modern high quality art book.

Has a fine latticework of sensors to detect the movements
12
Advantages
SmartPaper owns several advantages

It's reflective, like paper. You don't need a backlight, can view it
from an angle and in bright sunlight.

The screens can be tiled to create large signs, But unlike many
current electronic signs, the messages can easily be changed
periodically throughout the day.

Unlike a digital display that must be refreshed dozens of times
per second, electronic paper is "bi-stable." Therefore consumes
less power.
13
Advantages(cont…)

Displays made with SmartPaper generally do not degrade over time
and will last for years because the images are based on pigments
rather than dyes.

Signs made with SmartPaper have performed more than 5 million
image changes without malfunction or fading.

Images displayed on SmartPaper are "held" indefinitely until a new
electrical signal is applied.
14
Disadvantages

Resolution for SmartPaper is at least 100 dots per inch.Therefore
images on Smartpaper are gray, grainy, and otherwise visually
unimpressive.

The company is working on colored displays. But colored pigments,
which are needed to display the same charge properties as black
and white pigments, remain a technological hurdle.

It will never be as light as paper, Paper is about four mils thick; this
will always be 12 or 15 mils thick.

Applications

SmartPaper technology is well suited to a wide variety of other
market applications, including displays and electronic
books/newspapers.

Currently Smartpaper is finding its major use in Syncrosign
Message Board which is used for versatile and stylish display.

It combines Smartpaper with SignSync software,Gyricon’s unique
messaging software.
16
Applications(cont…)

The primary application for the SyncroSign Message Board is as a
dynamic information display. Corporate, educational and hospitality
can customize and control these eSigns throughout a large venue,
via a wireless network.

SyncroSign Message Board provides accurate content; displaying
daily agendas, seminar schedules, and other event information in
corporate classrooms, conference rooms or hotel lobbies.

Conclusion

Smartpaper is capable of projecting simple images with text but in
the future color photos and other graphics might become a reality
for electronic paper.

Smartpaper is very useful for data derived from books.Future
libraries may offer scanned images of books for download instead
of lending books.It is useful as a replacement for hardcopy.

Space colonies with no cellulose to spare for paper will be glad for
smartbooks.Smartbooks can store lots of data.
18

Data for smartbooks is produced and published digitally.

A future internet may have cores of “library sites” where people can
download contents for their smartbook.

It makes graphics tablet unneccessary.
