Abstract :
Electronic
paper, also called e-paper, is a display technology designed to mimic the appearance
of ordinary ink on paper. Unlike a
conventional
flat
panel display, which uses a backlight 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 changed
later.
To
build e-paper, several different
technologies exist, some
using plastic substrate and
electronics so that the display is
flexible. E-paper is
considered more comfortable to read
than conventional displays.
This is
due to the stable image,
which does not need to
be refreshed constantly,
the wider viewing angle, and
the fact that it
uses reflected ambient light. While it is lightweight
and durable, it still lacks
good
color reproduction. The
contrast ratio in common devices as of 2008 might be described as
similar to dirty newspaper, though newly-developed
implementations are slightly better.
Applications
include e-book readers
capable of
displaying digital
versions of books and e-paper
magazines, electronic
pricing labels
in retail
shops, time tables at bus stations electronic billboards, and
the mobile phone Motorola FONE F3. Electronic
paper should not be confused with digital
paper,
which is a pad to
create handwritten
digital documents
with a digital pen.
Advantages
Conventional displays
have
a number of
disadvantages in this
application. They may be too expensive,
too power consuming,
or too hard to see when affixed to a shelf. On the
other hand, e-paper
can produce small, battery-operated,
flexible displays.
E-paper’s
potential flexibility can
also be an advantage when affixing displays to shelves. Conversely, e-paper’s
current limitation-poor color capability-is not
much of a disadvantage in this
context. Color
is not a requirement; monochrome
displays would be quite capable
of displaying most pricing or
product information.
When
improved color
is developed, it would then increase the advertising capabilities of
such displays.
There is
tremendous
opportunity here as
stores
have ongoing problems
with changing prices for
promotions and other variables. Smart
shelving would also add value
by
reducing incorrect
pricing on the shelves; the bane of every customer.
From the e-paper industry point of view the
volume of displays would
be very large because of
the number of items in
any given
store
that need pricing information.
Hundreds of displays are
likely. However,
such
displays would be very small (2
to 3 inches).
Disadvantages
Like all technologies, E-paper
has its flaws that make it inaccurate
to use. Organizations face
many
disadvantages
with e-paper and e-paper
technologies.
Publishing departments may have a
bad time adapting to
this new technology because it is still
complex to use. Organizations still have manufacturing costs that were higher
than expected, and
some companies had trouble programming signs
in their stores.
Hence, companies are still reluctant to
use this technology because
it is more complex than paper and
it is more expensive to use. Also, e-paper
is still less attractive to technologies such as LED
or LCD,
because it still unable to reproduce animations and
it is difficult to read
when
there’s
no light.
Thus,
unless the room is not bright
enough,
employees in
an organization
will have a very hard
time reading the e-paper. The biggest challenge a company faces
with e-paper
and its sister technologies
is piracy.
In this
internet era,
it is easy to
send information from one side of
the globe to another, thus, organizations have to be careful with their
information. For example, your file
can
be easily emailed
to someone living thousands
of miles away. It
can
even be placed
in a
public server for
anyone to download.
Hence,
this could be troublesome for book publishing companies that may lose millions
of dollars and for organizations that
have classified information.
Searching is one of the most used actions on the Internet. Search engines as an instrument of searching, are very popular and frequently used sites. This is the reason why webmasters and every ordinary user on the Internet, must have good knowledge about search engines and searching.
