What Is 3D TV?
A motion picture that
enhances the illusion
Special projection hardware and/or
are used to provide the illusion
of depth when viewing the final image.
How 3D Technology Works
To understand the basic 3D technology techniques,
It is important to first
understand how the
Human beings have..
apart from each other
Works the Same Way
In order to produce this same kind of space in your brain, it requires
tricking your brain into seeing two different images
from the same source.
This distance between the two eyes produce
two slightly different images
which are transmitted to the brain.
The brain will then make a space in where
can be perceived
Let you view two different images of the same object taken from a different position and trick your brain into seeing one 3D image.
There are main kinds of 3D glasses
They are the ones that
don’t have any electronics
and they employ a different way to dissect the images.
If you have been to the
to watch a 3D film, you’ll be familiar with passive 3D.
You don't need any kind of expensive, delicate electronics in the glasses themselves, so passive glasses are
Passive 3D Features
They are the ones which
have got electronics
that are meant to change the display.
TVs with active 3D have a

Types of 3D Technologies
Glasses-free 3D Screens
It is the third technology, which is surely going to become more popular in future.
No viewing aid such as glasses has to be used.
The History of the 3D Technology
first commercial test
of a 3D stereoscopic film was shown to the audience at the Astor Theatre in New YorkCity.
very first 3D moving picture
was shown to a paying audience in Los Angeles called
The Power of Love
1952 – 1954
Was known as the “

Every studio had to produce their catalogue of 3D.

began producing 3D films, inspiring a resurgence that grew in the 90’s and early 2000’s.
William Friese-Greene found a way to capture moving pictures on
and project them using the “
He called his 3D films “
” images, which would become the early accepted term for 3D.
He projected the movie on
2 different screens
side by side. With a special viewer, audiences would look at the 2 screens and they would give the illusion of a 3D image.
Greene gave a
of a “stereoscopic” moving picture, but it failed to impress due to
poor sound and image.
James Cameron film,
Ghosts of the Abyss
, was shot in 3D video instead of film.
That film brought 3D back to mainstream.
The Mann’s Chinese 6 Theatre in Hollywood became
the first theatre
to be equipped with digital 3D format.

3D television is the latest evolution in the world of HDTV displays, adding the
perception of depth
to traditional 2D pictures that we have been watching for some time.
Perhaps at the expense of resolution and clarity as a whole.
3D TVs generally work by delivering
to each of the viewer’s eye.
The brain is then responsible for
these separate images to create an illusion of 3-dimensional depth.

A great 3D picture will give a good sense of overall

Some people, who try to watch a 3D movie or to play a 3D game often experience certain symptoms such as
cannot be pirated
so therefore a big gain for the movie industry because people will not lose money through illegal internet downloads.
Extreme localized differences
between the image to be displayed in one eye and the other may lead to
where you see a double image due to blurriness.
Results showed that both
viewing experience and naturalness were rated higher in 3D than in 2D
when the same noise level was applied.
Viewers who watched the movie segments in 3D reported a greater
sense of presence
than those who watched the segments in 2D.
It is believed that approximately
12% of people are unable to properly see 3D images
, owing to a variety of medical conditions.
According to another experiment up to
30% of people have very weak stereoscopic vision
preventing depth perception based on stereo disparity.

In Egypt, 3D movies are available at theatres of:
For the first time in Egypt,
the first 3D Smart TV
was released by
in April 2013.
Arabian Nights (Alf Leila We Leila) is
the first Egyptian 3D film
that will be broadcast soon - as announced previously.
What is beyond 3D TV
What is beyond 3D TV
Beyond 3D Technology, there are:
Curved OLED screens
4K refers to the horizontal resolution of such screens as they are all about
the resolution of the current 1080p HD standard and is best appreciated up close.
Also known as "
The 85-incher (216cm) offers more detail than a 33-megapixel photo.
By contrast 1080p offers about 2MP.
Curved OLED screens
An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which
emits light in response to an electric current.
Electronics have both produced curved OLED televisions with a curved display.
Both companies recognized their respective curved OLED prototype television as a first-of-its-kind due to its

One benefit is that
and other viewers wanting to be close to the action can stand close to the picture without worrying about casting a shadow.
Water TV Screen
It sees a humidifier to create a curtain of air made out of
tiny water particles
that feels dry to the touch, but is substantial enough to project an image on to.
It is interactive!
Built-in cameras and software algorithms analyze your hand movements so that you can manipulate the image.
