LED-backlight LCD Background and History
LED-backlight LCD television (incorrectly called LED TV by
Samsung Electronics, Panasonic, Toshiba, Philips, LG Electronics,
ProScan, Kogan, Sony and Vizio and not to be confused with trueLED displays) i
s an LCD TV that uses LED backlighting[1][2] rather than cold
cathode fluorescent lights (CCFLs) used in traditional LCD
televisions. This has a dramatic impact resulting in a thinner panel
and less power consumption, brighter display with better contrast
levels. It also generates less heat than regular LCD TVs.
The LEDs can come in three forms: dynamic RGB LEDs which are
positioned behind the panel, white Edge-LEDs positioned around the
rim of the screen which use a special diffusion panel to spread the
light evenly behind the screen (the most common) and full-array
which are arranged behind the screen but they are incapable of
dimming or brightening individually. [3][4]
TV manufacturers can use an LED backlight instead of the standard
Cold Cathode Fluorescent Lamps (LCD-CCFL) used in most LCD
televisions. It is important to distinguish this method of simply
backlighting a conventional LCD panel, from a hypothetical true LED
display, or an Organic light-emitting diode (OLED) display. LCD-based televisions described as 'LED TVs' are vastly different from
self-illuminating OLED, OEL or AMOLED display technologies. In
terms of the use of the term 'LED TV' in the UK, the ASA
(Advertising Standards Authority) has made it clear in prior
correspondence that it does not object to the use of the term, but
does require it to be clarified in any advertising. There are several
methods of backlighting an LCD panel using LEDs including the use
of either White or RGB (Red, Green and Blue) LED arrays
positioned behind the panel; and Edge-LED lighting, which uses white
LEDs arranged around the inside frame of the TV along with aspecial light diffusion panel designed to spread the light evenly
behind the LCD panel.
An LED backlight offers several general benefits over regular CCFL
backlight TVs, typically higher brightness. Compared to regular CCFL
backlighting, there may also be benefits to color gamut. However
advancements in CCFL technology mean wide color gamuts and
-

lower power consumption are also possible. The principal barrier to
wide use of LED backlighting on LCD televisions is cost.
The variations of LED backlighting do offer different benefits. The
first commercial LED backlit LCD TV was the SonyQualia 005
(introduced in 2004). This featured RGB LED arrays to offer a
color gamut around twice that of a conventional CCFL LCDtelevision (the combined light output from red, green and blue LEDs
produces a more pure white light than is possible with a single white
light LED). RGB LED technology continues to be used on selected
Sony BRAVIA LCD models, with the addition of 'local dimming' which
enables excellent on-screen contrast through selectively turning off
the LEDs behind dark parts of a picture frame.
Edge LED lighting was also first introduced by Sony (September
2008) on the 40 inch BRAVIA KLV-40ZX1M (referred to as the
ZX1 in Europe). The principal benefit of Edge-LED lighting for LCD
televisions is the ability to build thinner housings (the BRAVIA KLV-
40ZX1M is as thin as 9.9mm). Samsung has also introduced a range
of Edge-LED lit LCD televisions with extremely thin housings.
LED-backlit LCD TVs are considered a more sustainable choice,
with a longer life and better energy efficiency than plasmas and
conventional LCD TVs.[10] Unlike CCFL backlights, LEDs also use no
mercury in their manufacture. However, other elements such as
gallium and arsenic are used in the manufacture of the LED emitters
themselves, meaning there is some debate over whether they are a
significantly better long term solution to the problem of TV disposal.
Because LEDs are able to be switched on and off more quickly than
CCFL displays and can offer a higher light output, it is theoreticallypossible to offer very high contrast ratios. They can produce deep
blacks (LEDs off) and a high brightness (LEDs on), however care
should be taken with measurements made from pure black and pure
white outputs, as technologies like Edge-LED lighting do not allow
these outputs to be reproduced simultaneously on -screen.
In September 2009 Nanoco Group announced that it has signed a
joint development agreement with a major Japanese electronics
company under which it will design and develop quantum dots for
LED Backlights in LCD televisions.[11] Quantum dots are valued for
displays, because they emit li ght in very specific gaussiandistributions. This can result in a display that more accurately
renders the colors than the human eye can perceive. Quantum dots
also require very little power since they are not color filtered. In
September 2010, LG Electronics revealed their new product which
claimed as the world's slimmest full LED 3D TV at the IFA consumer
electronics trade show in Berlin.

The Truth About LED T.V
s
When a pro
uct has become commo
itize
an
its price is regularly
ropping an
its profit margins are getting ever-thinner, how can a
company boost its sales an
raise its prices?
Samsung 8000 Series LED TV
One way is by changing the pro
uct
s name.
That
s what Samsung has
one with its new line of LCD TVs using
LEDs to illuminate the screen. In its print a
vertising an
on its Web
site, Samsung calls the new range simply e LED TVs.f
They are not LED TVs. Calling them such makes as much sense as
calling its existing line of LCD televisions Col
Catho
e Fluorescent
Lamp TVs, or CCFL TVs, after the lighting technology that they
use.
Whatever its vali
ity, Samsung
s
ecision to
rop e LCDf was a
smart marketing move. After all, e LEDf is the acronym
u jour, a
technology that
s all the rage as a new, perhaps revolutionary
lighting source. It
s as emotive a term as e HDTVf an
e
igitalf
were in their hey
ays.
But it
s also confusing consumers. An in
ustry colleague tol
me
that in a recent trip to a big-box retailer, he overhear
severalfrien
s asking what type of TV they were watching. One sai
it
wasn
t LCD or plasma, it was an LED set.
More accurately, it was an expensive LCD set. LED-backlit LCD
TVs can cost as much as twice their stan
ar
LCD or plasma
counterparts. Is the extra money worth it, even if you can affor
it?

Here are the answers to some questions you may have about LCD
TVs using LED backlighting.
What
s wrong with existing LCD TVs?
Up until now, LCDs use
fluorescent tubes to light the screen. As a
result, LCDs have trouble creating
eep blacks. That
s because
fluorescent tubes are always on, an
some light leaks through tothe front of the
isplay even when a part of the image is suppose
to be black. A lack of
eep blacks re
uces the perceive
sharpness
of the set
s image.
Also, fluorescents lack a wi
e range of colors; hence, color
saturation is limite
.
What
s an LED TV?
It
s an LCD TV that uses LEDs to illuminate the
isplay. There are
two ways to
o this: either by placing LEDs across the entire back
of the
isplay, or by placing LEDs just aroun
the perimeter, which
is calle
an e e
ge litf
isplay. Both techniques use less power
than plasma TVs an
LCD TVs lit with fluorescent tubes.
Which technique is better?
They both have their pros an
cons. LCD TVs using e
ge-lit LCDs
can be ultra-thin, because the LED sources are on the si
e. E
ge-
lit LED-lit LCDs are also less expensive than LCD TVs using LED
backlit technology.
On the other han
, LCD TVs that use LEDs across the rear of the
isplay can create sharply
eeper blacks, through a technique calle
e local
imming.f When a scene calls for a
ark image, the LEDs in
that area can be shut off completely, so no light leaks through
what shoul
look black.So if I want an LED-lit LCD, I shoul
buy one using back-lit
technology?
It
s not so simple. An LED back-lit TV may contain only about
1,000 LEDs. An
those LEDs can only be
imme
in large groups,
because it is too expensive to contro l each LED in
ivi
ually. So
when you shut off or
im a group of LEDs you may also be
arkening part of an a
joining scene on the TV that really shoul
be
bright. If you cut back on the
imming, then the blacks will be less
ark than blacks in another part of the image that are not
surroun
e
by lighter images.Theoretically, you coul
increase the number of LEDs so that each
lit just one pixel on the 2 million pixel LCD screen. But then you
coul
just throw away the LCD screen because you woul
have
actually create
an LED television just like the Walgreens LED
sign in Times Square.

Samsung engineer said to me last week, e the most dramatic effect
of LED-lit TVs happens when the entire scene goes to blackf
not necessarily when youd re watching a scene with a mixture of
light and dark images.
Do LED-lit LCD TVs produce better pictures than plasma TVs?
Interestingly, Id ve heard no one in the industry claim that they do.At best, they say that with LED-lit LCD TVs, plasma no longer has
an edge when it comes to creating deep blacks and saturated
colors. But plasma still has a big edge when it comes to price.
How much more do LED-lit LCD TVs actually cost?
Right now, a lot. But that should change as more companies enter
the market. The list price for Samsungd s 46-inch high-end LED-lit
LCD TV, model UN46B8000, is $3,200. But its larger 50-inch plasma
high-end model, the PN50B860, is $800 cheaper.
Later this year, LG will introduce two new series of LED LCD TVs,
in 42-, 47-, and 55-inch screen sizes; all sets will use backlit LED
technology. Prices have not been announced.
Not surprisingly, Vizio has just broken the LED price barrier. On
Monday, the company announced that beginning this September it
would ship the VF551XVT, a 55-inch LCD model using LED
backlighting. The price: $2,200, or $1,000 less than Samsungd s
smaller 46-inch LED-lit television. It looks like Samsungd s strategy
to make its LED-based LCD TVs a premium product may have a
short life.
3D Tv
3d TV is designed to add real life to your viewing experience. The
days of visiting cinemas with 3d vision specs to specially watch a
film in 3d will become a thing of the past. Panasonic 3d TVs are
leading the way to make your viewing experience much more
enhanced. Panasonic is set to delivering the 3d format on blu ray to
be viewed on plasma TVs.
The arrival of the 3d television technology is causing quite a stir
within the industry, with competitors watching carefully of theprogress that Panasonic is making in the 3D TV market. Others are
looking to follow swiftly. In fact Panasonic is attempting to
encourage other companies to follow the 3D TV standard. To help
the progress of 3D TVs, it has made its technology non
proprietary.
Samsung is also following suit and already has 3d TV models that
are bringing a livelier TV viewing experience to the home. There are
-
8/8/2019 Led3dtv's - What they dont tell you instore!
6/24
models that have been demonstrated to show 3d TV content,
irrespective of the 3d standard being present or not. The 2d
content is converted into 3d format on existing blu ray players
made by Samsung to virtual 3d TV quality.
Year 2010 is the year when 3d TV really starts hitting our homes
to enable us to enjoy a much enhanced viewing experienced thatwas unthinkable a few years ago. So say good bye to the cinema
trips and enjoy the 3D TV experience right from the comfort of
your own armchair.
Real-Time 3D TV (Youtube video) is essentially a form of
autostereoscopic display.
Stereoscopy is the most widely accepted method for capturing and
delivering 3D video. It involves capturing stereo pairs in a two-view
setup, with cameras mounted side by side, separated by the same
distance as between a person's pupils. If we imagine projecting an
object point in a scene along the line-of-sight (for each eye, in
turn) to a flat background screen, we may describe the location of
this point mathematically using simple algebra. In rectangular
coordinates with the screen lying in the Y-Z plane (the Z axis
upward and the Y axis to the right) and the viewer centered along
the X axis, we find that the screen coordinates are simply the sum
of two terms, one accounting for perspective and the other for
binocular shift. Perspective modifies the Z and Y coordinates of the
object point by a factor of D/(D-x), while binocular shift
contributes an additional term (to the Y coordinate only) ofs*x/(2*(D-x)), where D is the distance from the selected system
origin to the viewer (right between the eyes), s is the eye
separation (about 7 centimeters), and x is the true x coordinate of
the object point. The binocular shift is positive for the left-eye-
view and negative for the right-eye-view. For very distant object
points, it is obvious that the eyes will be looking along the same line
of sight. For very near objects, the eyes may become excessively
"cross-eyed". However, for scenes in the greater portion of the
field of view, a realistic image is readily achieved by superposition
of the left and right images (using the polarization method orsynchronized shutter-lens method) provided the viewer isn't too
near the screen and the left and right images are correctly
positioned on the screen. Digital technology has largely eliminated
inaccurate superposition that was a common problem during the era
of traditional stereoscopic films.[5][6]
Multi-view capture uses arrays of many cameras to capture a 3D
scene through multiple independent video streams. Plenoptic

cameras, which capture the light field of a scene, can also be used
to capture multiple views with a single main lens. [7] Depending on the
camera setup, the resulting views can either be displayed on multi-
view displays, or passed for further image processing.
After capture, stereo or multi-view image data can be processed
to extract 2D plus depth information for each view, effectivelycreating a device-independent representation of the original 3D
scene. This data can be used to aid inter-view image compression
or to generate stereoscopic pairs for multiple different view angles
and screen sizes.
2D plus depth processing can be used to recreate 3D scenes even
from a single view and convert legacy film and video material to a
3D look, though a convincing effect is harder to achieve and the
resulting image will likely look like a cardboard miniature.
[edit] TV sets
These TV sets are high-end and generally include Ethernet, USB
player and recorder, Bluetooth and USB Wi-Fi.
[edit] 3D-ready TV sets
3D-ready TV sets are those that can operate in 3D mode (in
addition to regular 2D mode), in conjunction with a set-top-box
and LCD shutter glasses, where the TV tells the glasses which eye
should see the image being exhibited at the moment, creating a
stereoscopic image. These TV sets usually support HDMI 1.4 and a
minimum (input and output) refresh rate of 120 Hz; glasses may be
sold separately.
Panasonic already has several sets in the market (like the
Panasonic Viera TC-P50VT200 which are 3D capable and comeshipped with glasses. It has a retail price of approximately
US$2,500. The Samsung UN46C7000 46-Inch 3D TV can be
purchased for US$2,000.00 or less. There are numerous, relatively
inexpensive models available from a number of manufacturers
already in the summer of 2010.
Mitsubishi and Samsung utilize DLP technology from Texas
Instruments. [8] As of January 2010, Samsung, LG,[9] Toshiba, Sony,
and Panasonic all had plans to introduce 3D capabilities (mostly in
higher-end models) in TVs available sometime in 2010. [10]3D Blu-ray
players went on sale in 2010, and Sky began 3D broadcasts in theUK on 3 April 2010. DirecTV broadcasts began with the 2010 FIFA
World Cup in June 2010.[10] Samsung began selling the UN55C7000,
its first 3D ready TV, late in February 2010.[11]
Philips was developing 3D television sets that would be available for
the consumer market by about 2011 without the need for special
glasses (autostereoscopy).[12] However it was canceled due to the
slow adaptation of customers going from 2D to 3D.
-

In August 2010, Toshiba announced plans to bring a range of
autosteroscopic TVs to market by the end of the year. [13]
The Chinese manufacturer TCL Corporation has developed a 42-
inch (110 cm) LCD 3D TV called the TD-42F, which is currently
available in China. This model uses a lenticular system and does not
require any special glasses (autostereoscopy). It currently sells forapproximately $20,000.[14] The biggest problem using lenticular lens
as used also by Philip Dimenco is the sharpness of the display.
Although we use 4K (4 times of Full HD TV), the image we saw was
coarse in appearance due to lenticular lens technology required to
refract the left and right images for each eye, so the technology
used is certainly better suited for non-stationary viewing. The
border around objects in the screen tended to shift quickly and
blur.[15]
LG, Samsung, Sony & Philips intend to increase their 3D TV offering
with plans to make 3D TV sales account for over 50% of their
respective TV distribution offering by 2012. It is expected that the
screens will use a mixture of technologies until there is
standardisation across the industry.[16]. Samsung offers the LED
7000, LCD 750, PDP 7000 TV sets and the Blu-ray 6900.[17]
On June 9, 2010, Panasonic unveiled a 152 inches (390 cm) 3D-
capable TV (the largest so far) that will go on sale within 2010.
The TV, which is the size of about nine 50-inch TVs, will cost more
than 50 million yen (US$576,000).[18]
[edit] Full 3D TV setsFull 3D TV sets include Panasonic Full HD 3D (1920X1080 p, this is,
2 Mp; and 600 Hz). These TVs are expensive.
Toshiba has shown 20 and 12 inch autostereoscopic (this is,
glassesfree) LCD 3D TV sets for commercial launch, with a
1,280X720 resolution. By systematically aligning pixels and adopting
a perpendicular lenticular sheet, Toshibas LCD panel eliminates
blurring, or the vertical wave pattern (caused by interference in
the display cycle) that plagues other autostereoscopic 3-D
technologies. The viewing angle is about 40, doubling the previous
approaches, with.The 12 inch model will sell for roughly $1400.
Standardization efforts
The entertainment industry is expected to adopt a common and
compatible standard for 3D in home electronics. To present faster
frame rate in high definition to avoid judder, enhancing 3-D film,
televisions and broadcasting, other unresolved standards are the

type of 3D glasses (passive or active), including bandwidth
considerations, subtitles, recording format and a Blu-ray standard.
With improvements in digital technology, in the late 2000s, 3D
movies have become more practical to produce and display, putting
competitive pressure behind the creation of 3D television standards.
There are several techniques for Stereoscopic Video Coding, andstereoscopic distribution formatting including anaglyph, quincunx, and
2D plus Delta.
Content providers, such as Disney, DreamWorks, and other
Hollywood studios, and technology developers, such as Philips,
asked[when?]SMPTE for the development of a 3DTV standard in
order to avoid a battle of formats and to guarantee consumers
that they will be able to view the 3D content they purchase and to
provide them with 3D home solutions for all pockets. In August
2008, SMPTE established the "3-D Home Display Formats Task
Force" to define the parameters of a stereoscopic 3D mastering
standard for content viewed on any fixed device in the home, no
matter the delivery channel. It explored the standards that need to
be set for 3D content distributed via broadcast, cable, satellite,
packaged media, and the Internet to be played-out on televisions,
computer screens and other tethered displays. After six months,
the committee produced a report to define the issues and
challenges, minimum standards, and evaluation criteria, which the
Society said would serve as a working document for SMPTE 3D
standards efforts to follow. A follow-on effort to draft a
standard for 3D content formats was expected to take another 18
to 30 months.[citation needed]Production studios are developing an increasing number of 3D titles
for the cinema and as many as a dozen companies are actively
working on the core technology behind the product. Many have
technologies available to demonstrate, but no clear road forward
for a mainstream offering has emerged.
Under these circumstances, SMPTE's inaugural meeting was
essentially a call for proposals for 3D television; more than 160
people from 80 companies signed up for this first meeting. Vendors
that presented their respective technologies at the task force
meeting included Sensio,
[19]
Philips, Dynamic Digital Depth(DDD),TDVision[3], and Real D, all of which had 3D distribution
technologies.
However, SMPTE is not the only 3D standards group. Other
organizations such as the Consumer Electronics Association(CEA),
3D@home Consortium, ITU and the Entertainment Technology Center
at USC's School of Cinematic Arts(ETC), have created their own
investigation groups and have already offered to collaborate to
-

reach a common solution. The Digital TV Group (DTG), has
committed to profiling a UK standard for 3DTV products and
services. Other standard groups such as DVB, BDA, ARIB, ATSC,
DVD Forum, IEC and others are to be involved in the process.[citation
needed]
MPEG has been researching multi-view, stereoscopic, and 2D plusdepth 3D video coding since the mid-1990s;[20] the first result of
this research is the Multiview Video Coding extension for MPEG-4
AVC that is currently undergoing standardization. MVC has been
chosen by the Blu-ray disc association for 3D distribution. The
format offers backwards compatibility with 2D Blu-ray players.[21]
HDMI version 1.4, released in June 2009, defines a number of 3D
transmission formats. The format "Frame Packing" (left and right
image packed into one video frame with twice the normal
bandwidth) is mandatory for HDMI 1.4 3D devices. All three
resolutions (720p50, 720p60, and 1080p24) have to be supported
by display devices, and at least one of those by playback devices.
Other resolutions and formats are optional.[22] While HDMI 1.4
devices will be capable of transmitting 3D pictures in full 1080p,
HDMI 1.3 does not include such support. As an out-of-spec
solution for the bitrate problem, a 3D image may be displayed at a
lower resolution, like interlaced or at standard definition.
[edit] DVB 3D-TV standard
See also: High-definition television
DVB has established the DVB 3D-TV Specification. The following
3D-TV consumer configurations will be available to the public:[23]
y 3D-TV connected to 3D Blu-ray Player for packaged media.y 3D-TV connected to HD Games Console, e.g. PS3 for 3D
gaming.
y 3D-TV connected to HD STB for broadcast 3D-TV.y 3D-TV receiving a 3D-TV broadcast directly via a built-in
tuner and decoder.
For the two broadcast scenarios above, initial requirements are for
Pay-TV broadcasters to deliver 3D-TV services over existing HD
broadcasting infrastructures, and to use existing receivers (with
firmware upgrade, as required) to deliver 3D content to 3D-TV
sets, via an HDMI or equivalent connection, if needed. This istermed Frame Compatible. There are a range of Frame Compatible
formats. They include the Side by Side (SbS) format, the Top and
Bottom (TaB) format, and others.

As of 2008, 3D programming is broadcast on Japanese cable
channel BS 11 approximately four times per day.[24]
Cablevision launched a 3D version of its MSG channel on March 24,
2010, available only to Cablevision subscribers on channel 1300. [25][26]
The channel is dedicated primarily to sports broadcasts, including
MSG's 3D broadcast of a New York Rangers-New York Islandersgame, limited coverage of the 2010 Masters Tournament, and (in
cooperation with YES Network) a game between the New York
Yankees and Seattle Mariners.[27]
The first Australian program broadcast in high-definition 3D was
Fox Sports coverage of the soccer game Australia-New Zealand on
24 May 2010.[28]
Also in Australia, the Nine Network and Special Broadcasting
Service will be bringing the State of Origin (matches on 26 May, 16
June and 7 July 2010) (Nine) and FIFA World Cup (SBS) in 3D on
Channel 40 respectively. [29]
Earlier this year (2010) Discovery Communications, Imax and Sony
announced plans to launch a 3D TV channel in the US with a planned
launch in early 2011.[30] At the same time, a Russian company
Platform HD and its partners General Satellite and Samsung
Electronics announced about their 3D television project, which
would be the first similar project in Russia.
In Brazil Rede TV! became the first Terrestrial television to
transmit 3D signal freely for all 3D enabled audience on 21 May. But
despite their technology, its programming is still in poor
quality.[31][32][33][34]
Starting on June 11, 2010 ESPN launched a new channel, ESPN 3D,dedicated to 3D sports with up to 85 live events a year in 3D.[35]
On 1 January 2010, the world's first 3D channel, SKY 3D, started
broadcasting nationwide in South Korea by Korea Digital Satellite
Broadcasting. The channel's slogan is "World No.1 3D Channel". This
24/7 channel uses the Side by Side technology at a resolution of
1920x1080i. 3D contents include education, animation, sport,
documentary and performances.[36]
A full 24 hour broadcast channel was announced at the 2010
Consumer Electronics show as a joint venture from IMAX, Sony, and
the Discovery channel.
[37]
The intent is to launch the channel in theUnited States by year end 2010.
DirecTV and Panasonic plan to launch 2 broadcast channels and 1
Video on demand channel with 3D content[38] in June 2010. DirecTV
previewed a live demo of their 3D feed at the Consumer Electronics
Show held January 710, 2010.[39]
In Europe, British Sky Broadcasting (Sky) launched a limited 3D TV
broadcast service on April 3, 2010. Transmitting from the Astra2A

satellite at 28.2 east, Sky 3D broadcast a selection of live UK
Premier League football matches to over 1000 British pubs and
clubs equipped with a Sky+HD Digibox and 3D Ready TVs, and
preview programmes provided for free to top-tier Sky HD
subscribers with 3D TV equipment. This was later expended to
include a selection of films, sports, and entertainment programminglaunched to Sky subscribers on 1 October 2010. [40]
On September 28, 2010, Virgin Media launched a 3D TV on Demand
service,[41]
Several other European pay-TV networks are also planning 3D TV
channels[42] and some have started test transmissions on other
Astra satellites, including French pay-TV operator Canal+ which
has announced its first 3D channel is to be launched in December
2010. Also the Spanish Canal+ has started the first broadcastings
on May 18, 2010 and included 2010 FIFA World Cup matches in the
new Canal+ 3D channel. [43] Satellite operator SES Astra started a
free-to-air 3D demonstration channel on the Astra satellite at
23.5 east on May 4, 2010 for the opening of the 2010 ANGA
Cable international trade fair[44] using 3D programming supplied by
3D Ready TV manufacturer Samsung under an agreement between
Astra and Samsung to co-promote 3D TV.[45]
[edit] 3D episodes and shows
There have been several notable examples in television where 3D
episodes have been produced, typically as one hour specials or
special events.
The first-ever 3D broadcast in the UK was an episode of the
weekly science magazine The Real World, made by Television Southand screened only in the south-east region of the UK in February
1982. The programme included excerpts of test footage shot by
Phillips in the Netherlands. Red/green 3D glasses were given away
free with copies of the TV Times listings magazine, but the 3D
sections of the programme were shown in monochrome. The
experiment was repeated nationally in December 1982, with red/blue
glasses allowing colour 3D to be shown for the first time. The
programme was repeated the following weekend followed by a rare
screening of the Western Fort Ti starring George Montgomery and
Joan Vohs.The sitcom 3rd Rock From The Sun two-part episode "Nightmare
On Dick Street", where several of the characters' dreams are
shown in 3D. The episode cued its viewers to put on their 3D
glasses by including "3D on" and "3D off" icons in the corner of the
screen as a way to alert them as to when the 3D sequences would
start and finish. The episode used the Pulfrich 3D technique.

[edit] Health effects
Some viewers have complained of headaches and visual problems
after watching 3D TV and films. There have been several warnings,
especially for children.[54]
liquid crystal display (LCD) is a thin, flat electronic visual display
that uses the light modulating properties of liquid crystals (LCs).
LCs do not emit light directly.
They are used in a wide range of applications including: computer
monitors, television, instrument panels, aircraft cockpit displays,
signage, etc. They are common in consumer devices such as videoplayers, gaming devices, clocks, watches, calculators, and
telephones. LCDs have displaced cathode ray tube (CRT) displays in
most applications. They are usually more compact, lightweight,
portable, less expensive, more reliable, and easier on the eyes. [citation
needed] They are available in a wider range of screen sizes than CRT
and plasma displays, and since they do not use phosphors, they
cannot suffer image burn-in.
LCDs are more energy efficient and offer safer disposal than
CRTs. Its low electrical power consumption enables it to be used in
battery-powered electronic equipment. It is an electronically-modulated optical device made up of any number of pixels filled with
liquid crystals and arrayed in front of a light source (backlight) or
reflector to produce images in colour or monochrome. The earliest
discovery leading to the development of LCD technology, the
discovery of liquid crystals, dates from 1888.[1] By 2008, worldwide
sales of televisions with LCD screens had surpassed the sale of
CRT units.

Each pixel of an LCD typically consists of a layer of molecules
aligned between two transparentelectrodes, and two polarizing
filters, the axes of transmission of which are (in most of the
cases) perpendicular to each other. With no actual liquid crystal
between the polarizing filters, light passing through the first filterwould be blocked by the second (crossed) polarizer. In most of the
cases the liquid crystal has double refraction.[citation needed]
The surface of the electrodes that are in contact with the liquid
crystal material are treated so as to align the liquid crystal
molecules in a particular direction. This treatment typically consists
of a thin polymer layer that is unidirectionally rubbed using, for
example, a cloth. The direction of the liquid crystal alignment is then
defined by the direction of rubbing. Electrodes are made of a
transparent conductor called Indium Tin Oxide (ITO).
Before applying an electric field, the orientation of the liquid
crystal molecules is determined by the alignment at the surfaces of
electrodes. In a twisted nematic device (still the most common liquid
crystal device), the surface alignment directions at the two
electrodes are perpendicular to each other, and so the molecules
arrange themselves in a helical structure, or twist. This reduces the
rotation of the polarization of the incident light, and the device
appears grey. If the applied voltage is large enough, the liquid
crystal molecules in the center of the layer are almost completely
untwisted and the polarization of the incident light is not rotated as
it passes through the liquid crystal layer. This light will then be
mainly polarized perpendicular to the second filter, and thus beblocked and the pixel will appear black. By controlling the voltage
applied across the liquid crystal layer in each pixel, light can be
allowed to pass through in varying amounts thus constituting
different levels of gray. This electric field also controls (reduces)
the double refraction properties of the liquid crystal.[citati
3D gaming
3D gaming is soon set to move way beyond its current limited niche
in the hardcore PC market, with console manufacturers and game
developers increasingly eager to provide us with compelling
-

interactive content to play on the slew of new TVs set to hit the
shelves later this spring.
CES 2010 was, in many ways, a festival of 3D television tech, with
pretty much every major TV manufacturer unveiling its latest 3D HD
TV models many of which will see a commercial release later
next month.The runaway successes of movies such as James Cameron's Avatar
and Disney's UP have not only generated a much-welcome renewed
interest in cinema-going, but they will also drive 3D TV sales when
they arrive on Blu-ray later in 2010.
Sky is also launching the world's first 3D television station in April
which will drive consumer adoption further. Just like that imaginary
game of Tetris 3D we dreamed of the other night, the pieces are
starting to fall into place.
But what of 'proper' 3D gaming in our lounges? Are we still stuck
in that annoying catch-22 stalemate position, where publishers
won't invest the extra cash and developers won't go the extra mile
until a proven market (and that all-important return on investment)
is in place?
A brief history of 3D gaming
There have been numerous attempts to take console and handheld
and PC gaming into the third dimension in the last twenty years.
Most have been quickly (and rightly) dismissed by consumers as
little more than cheap headache-inducing gimmickry.
"We didn't worry so much about the past efforts, such as
Nintendo's Virtual Boy or things like that," says Dale H Maunu, an
analyst at 3D and display tech research firm Insight Media.
VIRTUAL BOY: Failed to ignite a 3D gaming revolution in the '90s
"3D gaming is really more recent, in terms of the ability to do
Stereoscopic 3D ("S-3D") gaming. The release of DirectX 8
ushered in the era of a standardized 3D API for MS Windows,
which resulted in game developers and publishers creating more 3D
assets in their games," adds Maunu.
"The move to DirectX 9 provided still more tools for game
developers and is really the minimum requirement for S-3D gaming;
many of the titles that can be played in S-3D were developed forDirectX 9."
Rewinding a couple of years back to 2008, there were already 3D
monitors and systems available from the likes of iZ3D and Zalman
for playing DirectX 9 games in S-3D. "The Zalman system used
drivers from DDD, while iZ3D developed their own," says Maunu,
adding, "the systems worked pretty well, but the drivers generally
needed to be hand-tweaked for each game since there was no
-

17/24
standard or API for S-3D. Plus, the game developers were not
directly involved in making their games work in S-3D so there was
still quite a bit of variability in the S-3D experience from game-
to-game."
It was really the introduction of Nvidia's 3D Vision tech early in
2009, along with its own S-3D API, that started to put somestandards in place for games developers and games buyers.
"World of Warcraft introduced support for 3D Vision in early 2009,
and Nvidia was able to convince many developers to support S-
3D," says Maunu. And some cracking 3D-optimised PC titles soon
followed including the likes of Left 4 Dead 2, Resident Evil 5,
Batman: Arkham Asylum and, most recently, the game spin-off of
Avatar from Ubisoft.
TechRadar spoke with Patrick Naud, Ubi's Executive Producer of
Avatar, who told us that working on 3D "was a great experience
for our teama any time we can get out there and be one of the
first on a new technology like this, you get a boost of creativity,
and we had a lot of fun coming up with great ways to use the
innovation to make a game that puts the player right into the
environment and action.
"I personally see a lot of potential with combining 3-D with Natal,"
says the Avatar game producer. "These two technologies together
will bring us even more immersive experience to gameplay."
The S-3D Gaming Alliance
Neil Schneider is the Executive Director of the S-3D Gaming
Alliance (S3DGA) - the non-profit and non-proprietary
organisation that is generally considered to be the official voice andstandards body for stereoscopic 3D gaming.
Schneider disagrees with analysts such as Dale Maunu who claims
that S-3D gaming is a recent phenomenon in gaming, telling
TechRadar that, "modern S-3D gaming has been around for a
whopping twelve years!" (The S3DGA has put together its own
potted history of S-3D gaming, and you can see Part 1 and Part 2
of that over on YouTube (Part 3 is currently in the works)).
Schneider also points out that while Nvidia's own 3D marketing
suggests 400 compatible video games, "this is for depth-only
situationsa . [and] once gamers attempt out of screen or pop-outsettings, anomalies become much more prevalent, and this
compatibility list is greatly reduced. Similar results can be expected
from additional driver developers like DDD and iZ3D."
"This is one of the reasons why S3DGA was founded. We want that
400+ game support, and we want it industry-wide."
Schneider also adds that he considers it inappropriate to give all
credit Nvidia for developing S-3D standards. "This is not the case

"Game developers on the other hand already have all that
information readily available. In fact we spend a great deal of time
trying to make 3D worlds display well on a 2D screen. To make
games work with 3D TV we already have the depth information
available we just need the means to convey that data to the
new TVs."
ust as new high definition TVs were marketed as 'HD ready',
expect the first wave of 3D-capable sets to wear a '3D Ready'
sticker.
DisplaySearch forecasts that 3D TV shipments will balloon from 0.2
million units in 2009 to 64 million units by 2018, raking in $17 billion
along the way. The revolution will be televised. And those with the
biggest wallets will enjoy it in 3D.
But what does '3D Ready' mean, and what defines a 3D Ready TV?
Samsung's 3D-capable 7000, 8000 and 9000 Series HDTVs, for
example, will include a proprietary 3D processor and emitter. These
are designed to be compatible with multiple 3D standards, including
half/full HD resolution formats and the recently finalised Blu-ray 3D
specification.
y Read: Top 10 3D TVs in the world todayAll of which suggests that the term '3D Ready' is just a catch-all
phrase for a less exciting (but more accurate) one 3D-capable.
3D TV size and refresh rateWhile there seems to be no restrictions in terms of TV size, a 3D
TV needs a minimum refresh rate of 120Hz (a basic 60Hz displayed
for each eye). The higher the refresh rate, the smoother the 3D
effect. So a 240Hz set will be capable of outputting 120Hz to each
eye.
HDMI 1.4 will also be required for full HD per eye viewing.
Until the broadcast industry settles on a standard, any '3D Ready'
badge will need a graphic depicting some fingers firmly crossed.
Blu-ray 3D is the closest that we currently have to an accepted
3D standard. The Blu-ray Disc Association has given the thumbs upto Multiview Video Coding, a variant of the existing high-def
H.264/MPEG-4 AVC codec. The world's first 3D Blu-ray disc,
Monsters Vs Aliens, was announced at CES 2010.
Of course, how you view 3D content has also not been set in
stone. Cinemas currently use three different types of 3D glasses
passive polarized glasses, active LCS glasses, and Infitec (Dolby 3 -
D) glasses.

guys are going crazy with numbers)
Cons:
This thing is FAT for a LED TV!! But for the Huge label reading
"LED", I would have considered it as another LCD. Absolutely nosize/weight advantage of LEDs. Specs show, it is heavier than LG
JAZZ LCD!!
I observed that, in HD, This panel is brighter than the Sammy (flat
settings), 3D effect is there but defenitely sammy is better. Both
the LEDs have far better PQ than LCDs. (Did not compare with
LCDs other than LG&Sammy).
HD content needs to be played from a HD DVD player..
Sound feels like coming from a old solidaire TV..
The angled view (Which IPS is famous for) is little less when
comparing this LG LCDs. But definety not to worry, Iam talking
about >150" which no one sees in real life..
Sammy..
Pros:
Exteremely ~~THIN~~ I mean wafer thin.. I fear if it will fly away
during the monsoon..
Design is to die for!! Look from the sides and you'll see only the
stand..
Looks gorgeous even when switched off! That is saying a lot.
SHARP Pictures.. Razor sharp is the word!! Not a single pixeldeviation to untrained eyes.
3D POP is there and it is not an illusion. (Background is very well
sperated from the foreground possibly by some post processing. it
is like depth of image in digital camera if you know..) IMO,
Defenitely LED backlighting is not the only reason for it. It must
have got a wonderful 3D engine which they do not put in normal

LCDs. It is better than LG.
5 KG lighter than LG (~15 vs ~20kg)
Cons:
No local dimming. Blacks are still grey if you notice hard. Can live
with it.
No BT
100 Hz vs 200 Hz of LG (Did not notice as there weren't any "so
much" fast moving demos.
Err Sound.. It is so thin and it must have been hard to fit in a
decent speaker there.. Still Better than LG by a small margin..Other LCDs (like Jazz) win hands down.
Other comparisons:
When in SD mode, there is little to no difference in PQ between the
two. There is this pop and blacker blacks and more contrast which
are noticably different from the normal LCDs. But if SD content is
what we watch daily (which is the case), Samsung felt exteremely
over priced. LG is still better.
Dark scenes with candle light (A demo DVD for plasma actually) is
better than normal LCDs but falls short (by quite a huge margin)
when compared to plasma. Even a very basic plasma which is just
40k played it well..
This is generic to all 16:9 TVs. Both played SD content well in 16:9.
I think I don't have to watch them with the black side bars.
Questions at the end: (For you guys)
1) Why is there still a 20k difference in pricing?
2) I can get a LG 47" LED for a 77k. Given that who will be
interested in Sammy?
3) Should I have a more closer look at plasmas? Till now, I was not
even considering them as knowledge from internet tells me that they
eat electricity, produce heat and have burn in (Meaning I cannot
-
8/8/2019 Led3dtv's - What they dont tell you instore!
23/24
watch SD content with side bars).
The store guy's version tells me that they sell plasmas to only
budget concious buyers (Buyers who will turn their backs after the
LCD demo). And that he genuinely feels that LCDs are better. Only
the plasma TV demo DVDs show plasmas as better but theprobablity of encountering such scenes in real life is less and when
we encounter, we might not even notice. Also, the LG LEDs are
real VFM and he would not buy the samsung with even the reduced
price.
What will I buy if given only the above two as choice.
IMO, The sammy has some features missing and slightly better PQ
of HD. SD PQ is almost the same except for a bit of sharpness.
Very very thin and beautiful but 25% costlier. It is 40" compared to
42" of LG.
Weighing the above I'd definetely go for the LG.
I would also have a second look at the plasma (dont remember.. LG
model.. PQ30 I think) more carefully before deciding anything. It is
27k cheaper than the cheapest LED and has comparable picture
quality and features..
3D PORN
's done. Game on, broheim, because 3D is here to stay. The first 3D porn full feature film made for
modern stereoscopic TVsthose that use shutter eyeglasseshas arrived. It's called Kama-Sutra, and
even Woody Allen will like it.That's what Allen said at the last Ca nnes Film Festival: "[I like 3D movies because] three-dimensional
women look a lot better. I don't see it in my movies, but for Playboy it will be perfect." Legendary
european porn producer Mark Dorcel agrees. That's why he made the first 3D porn film to prove it.
Called Kama-sutra, it stars Brigitte Lahaie. Dorcel thinks that not all porn will be 3D, however. Some
people will like it, others will prefer good old 2D. Being a fan of 8mm porn from the 60s, I agree.The new movie is more Avatarthan Alice in Wonderland. It doesn't include women painted in blue
thankfully-but it uses actual 3D cameras and not2D-to-3D post-processingthankfully. [Allocine
