Introduction
The Panasonic 3D Plasma TV uses what’s called “Frame Sequential Method”. By using this
method, the TV outputs alternating imagery at 60 frames per second to each eye. The brain
then combines the images and interprets them as 3D.
The PDP high-speed light emission technology utilized to display high-picture quality full HD
video images for the left and right eyes in frame sequential is unique to Panasonic.
The Panasonic 3D PDP utilizes new phosphor technology for “real deep black and
unsaturated brightness,” and employ proprietary 3D drive technology circuitry to minimize
crosstalk between alternating images.

Features
Full HD 3D Technology
For a true Full 1080p 3D image, Panasonic’s VT25 Series features new, faster screen phosphors
(short-stroke) which, when coupled with the VIERA VT25’s 600Hz sub-field drive, outputs
alternating imagery at 60 frames per second to each eye. Working in unison with the required
Active Shutter Eyewear, the human brain then combines the images and interprets them as a Full
HD 3D image for the highest possible realistic visual experience; in effect mimicking what the
human eye sees in real life.
Active Shutter Eyewear
All Panasonic VIERA VT25 Series models come with one pair of Panasonic 3D Active Shutter
Eyewear (TY-EW3D10U). Additional pairs of Panasonic 3D Eyewear are available at retail with an
SRP of $149.95.
Infinite Black Pro Panel
A new phosphor technology that produces deep blacks (5,000,000:1 native contrast)2 and vivid
images with minimal reflection.
THX Certified Display
Ensures that every Panasonic Full HD 3D TV displays motion pictures and television content with
exactly the quality and color palette that the director intended.
VIERA CAST WiFi with Skype Capability
Panasonic’s innovative Internet programming package, gives viewers the ability to access feature
films plus information and communication offerings including Amazon Video on Demand™,
Bloomberg News, Fox Sports, Netflix™, and Skype™ on Your VIERA TV3, among others.

New Plasma Display Panel
The new panel used on the 2010 3D plasma TVs has 3 areas of improvement:
1. Enlarge discharge area.
2. New filter.
3. Reduced pre-discharge.
1 - Enlarged Discharge Area (improves brightness and contrast with less power
consumption)
The new cell structure, materials, and phosphors made it possible to enlarge the
discharge area of each cell. This increases both brightness and contrast, so you enjoy a
bright, vibrant picture while using less energy.
Slide 10
Slide 10
New Plasma Display Panel
2 - A New Filter
(It blocks ambient light to increase
contrast and brightness)
A newly developed film minimizes
reflection from ambient lighting and
increases contrast. It also improves light
transmittance, which boosts brightness.
The result is reproduction of images that
look breathtakingly beautiful in any
viewing environment
3 - Reduced Pre-Discharge
(Reduces grey and enhances black
gradation)
To minimize light leakage, we found a
way to reduce the level of predischarge required for plasma light
emission. This helps achieve deeper,
richer blacks that give images
exceptional depth and presence
Slide 11
Slide 11
THX
THX reproduces film images exactly as the film's creators intended them.
The aim is to recreate the audio and visual ambience that filmmakers intended.
To receive THX certification, TVs undergo stringent tests to determine:
•If the exact same brightness and color are displayed at all screen locations.
•If black levels satisfy standard criteria.
Panasonic 3D Plasma TVs meets the high standards set by the THX Certified Display
Program.
Slide 12
Contrast Ratio
Note: Native Contrast is expressed as a ratio of the minimum of luminance levels
of blacks and the maximum of luminance levels of whites that are displayed and
measured at the same time on the same screen in a dark room on a plasma
panel module.
Panasonic's Native Contrast measurement expresses the maximum contrast ratio
of the plasma panel measured at the time of manufacture and does not express a
contrast ratio measured during ordinary viewing conditions by a consumer.
For 2010 plasma television models, Panasonic measures Native Contrast in a
Dynamic mode using a static white rectangular pattern with 4% area size. This
allows consumers to compare more easily the Native Contrast ratios reported for
Panasonic plasma televisions with the Dynamic Contrast ratios reported by many
manufacturers of LCD televisions.
Depending on the model, Native Contrast of the panel has been measured as
either 5,000,000:1 or 2,000,000:1. Unlike measurements taken for previous
models, Pre-Discharges do not occur for the images used in the 2010 model
measurements, so the results should not be compared to contrast ratios reported
for earlier year Panasonic models.
Most manufacturers use the Dynamic Contrast methodology in measuring
contrast ratios for LCD televisions. This methodology, unlike the Panasonic Native
Contrast ratio measurement for plasma televisions, compares the maximum
luminance levels on full white signal in one picture with the minimum luminance
levels on full black signal in another picture.

Precautions
■ View the screen at a distance at least 3 times the height of the screen.
Recommended distance:
For a 50-inch TV : 1.9 m (6.23359‘)
For a 54-inch TV : 2.0 m (6.56167’)
■ When watching 3D movies, take an appropriate length break after watching a movie.
■ When watching 3D content on interactive devices such as 3D games or computers,
take an appropriate length break after using for 30 - 60 minutes.
■ As a guide, 3D Eyewear should not be used by children younger than 5 - 6 years old.
As it is difficult to judge younger children’s reactions to fatigue or discomfort, you may not prevent them
from suddenly getting sick.
When this product is being used by a child, the parent or guardian should check to ensure that the child’s
eyes are not becoming tired.

■ When using the 3D Eyewear, do not place breakable objects near the user.
The user may mistake the 3D objects they are viewing as real objects causing him to move suddenly.
This may cause damage to surrounding objects leading to injury.
Slide 14
Can Everybody See 3D?
No. There’s a small percentage of human (5%~10% of Americans) that lack the ability to properly
see different images for each eye. This condition is called “Stereo Blindness”.
3D Technology
Slide 15Slide 15
3D Display Formats (Methods)
There are a few methods used to separate the left and right eye images on a 3D display:
Frame Sequential, Side by Side, Top and Bottom, Checker Pattern (Field Sequential), Line By Line
Frame Sequential
In the frame sequential method, images for each eye are alternately reproduced in its full resolution.
This means a separate 1920 x 1080 Full HD image is sent to each of eye, enabling the viewers to
fully immerse themselves in the 3D landscape presented.
Frame sequential is what the Blu-ray spec and active shutter TVs use.
Side By Side
broadcasts in which 2D and 3D feeds are run alongside each other to ensure a seamless simulcast to
the receiver. If signal is not processed as 3D, the image on the TV will look like 2 pictures side by
side.
Used by Direct TV
Top and Bottom
Normal video frame actually has 2 frames, one on top a
Manual setting is necessary. Blu-ray recorder do not support this format.
Checker Pattern (Field Sequential)
In the field sequential method, the screen is divided in clusters of pixels. Because the images are laid
out in a checkered pattern, the image data that reaches each eye only has only half the number of
pixels than that of a Full HD image thus resulting in a lower quality picture.
Line By Line
In the line-by-line method, the screen’s lines are divided into even and odd lines by a polarizer filter.
This encodes the light in a plane that the odd lines can be only perceived by the left eye and the even
only by the right eye. Because the data for both eyes is displayed on one image, the vertical
resolution is only 50 % of that of frame sequential technology, resulting in a lower quality picture. As
well: The polarizer filter with the polarizer glasses have limitations of its viewing angle – when sitting
higher or lower than the screen so called ghosting will appear.

3D Display Formats (Methods)
Line By Line, Checker Pattern (Field Sequential), Frame Sequential
A sequential
Blu-ray outputs the video at 1080p 24 frames per second, per eye; or 48 frames per second. This signal
goes to the TV but the glasses are what ensures each eye sees the correct image.
The side by side systems
24 frames per second. The TV receives this signal, splits it into two frames, displays them sequentially
and then stretches them out.
This is not as good as Blu-ray, but it uses way less bandwidth and makes it so that the TV Station (Like
DirecTV) can just release a firmware update instead of replacing all the set-top boxes. It is expected that
cable companies will use the same technique.
Auto-Stereoscopic TV is the future. The 3D image is created without the need for glasses, but
this is 10 to 15 years away.
3D TV can display sequential 3D, this means the TV converts it.

Frame Sequential Method
Frame Sequential Method
Panasonic uses full-HD sequential playback
to achieve a level of reality that far exceeds
conventional 3D systems. Called the Frame
Sequential Method, it's the same method
that is used in Hollywood's 3D films. It
reflects our commitment to 3D imaging
detail. Separate images recorded in 1920 x
1080-pixel resolution for both the left and
right eyes are alternately displayed at the
ultra-high speed of 120 frames per second.*
Viewing them with high-precision 3D
Eyewear produces 3D images in full-HD
quality.
Note: The frame rate varies depending on
the 3D image signal being reproduced. For
example, 3D images are reproduced at 120
fps (frames per second) for a 60Hz input
signal, and 100 fps for a 50Hz input signal.

Difference Between the Passive Plastic Glasses With Polarized Lenses Used at
the Movies and The Active Shutter System Glasses Used with 3D TVs
With active shutter glasses, crosstalk is eliminated easier than passive
glasses.
Crosstalk is a phenomenon where an image intended for one eye is seen by
the other, causing ghost images to appear.
With the active shutter glasses, both eyes can be closed off for a split
second between each frame. This reduces ghosting or crosstalk.
Passive glasses are used with TVs where a polarized filter in the TV has to
switch directions for each eye.

Procedures To Check The 3D Eyewear
Determining if a the 3D eyewear is working or not can be easily done if another set of working
eyewear is available.
When another set of eyewear is not available, perform the following tests to determine if the glasses
are OK:
1. Battery voltage check
2. Shutter operation check
1 - Battery voltage check
• Normal charge (2.5V to 3V) is indicated when the power switch is turned on and the Power LED
turns on for approximately 2 seconds and then it goes off.
• The Power LED blinks 3 times when the power is turned off.
• A low charge is indicated when the Power LED blinks for 5 times
power is turned on. The voltage at this point is between 2V to 2.5V.
Note: The IR receiving distance is shortened when the power-supply voltage decreases
• When the voltage drops below 2V, the power doesn't turn on (Replace the battery).

Digital or HD service subscription and a direct cable connection or an HD STB (Set-Top-Box)
are required.
• If a STB is used, an HDMI connection between the cable box and the TV is required.
• The TV or STB needs to be tuned to the channel with the 3D broadcast.
• Stereoscopic 3D glasses are required.
Customers should contact their cable or satellite service providers to see if they are subscribed to a
service which provides 3D content, or check their local listings for channels this will be carried on for
off air broadcasts.
The issue is that there may not be a "3D Content Flag" embedded in the signal which would cause
the TV to automatically change to the correct 3D Input Format, so customer may have to make this
change in the TV's menu manually. (They may need to manually change this setting until the
EDID/VSI information that will allow our TVs to automatically switch to 3D mode is included in the
broadcast).
