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. Access to a broadband Internet connection is required. Panasonic’s Communication Camera (TYCC10W) is required for Skype video functionality and sold separately

All Panasonic VIERA VT25 Series models also feature 600HZ Sub-field Drive, 1080p Lines Moving Picture Resolution, VIERA Image ViewerTM, VIERA LinkTM Connectivity with Network Cameras, 24p Cinematic Playback, two USB Ports, PC Input, and are ENERGY STAR 4.0 compliant.

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

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

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.

Slide 13

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.

or more

■ 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.

, a single 1080p frame that holds both the right and left eye's images is sent at

Slide 18

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.

Eyewear (EW3D10U)

EW3D10 Full HD 3D Eye-ware

High Precision shutter control sends clear images to each eye. Highly precise control completely closes the shutters for both eyes at the instant that the images change for the left and right eyes. This masks unwanted afterimages to enable clear and comfortable 3D viewing.

Features:

Adjustable, durable frame

The Eyewear can be easily adjusted to fit various face shapes and sizes, from children to adults.

Designed for use together with ordinary glasses

The 3D Eyewear can also be comfortably worn right over ordinary prescription glasses.

Power on/off switch

An Auto Power Off function automatically turns the glasses off if they are placed in a location outside the viewing range minutes, even if the TV remains turned on.

Slide 23

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.

Slide 24

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).

Procedures To Check The 3D Eyewear

2 - Shutter operation check

Check shutter open/close operation by changing 2D/3D select switch on the user menu.

The liquid crystal shutter open/close timing is controlled by receiving IR signals from the TV, which provide 3D expression of the images.

1. Change the switch to 3D and 2D, repeatedly.

2. Glass color is changed to dark and bright by detecting a Shutter On/Off signal from TV if they are working propely.

3D Auto 3D 2D

TV outputs IR signal from 2 positions. Even if one IR signal is blocked, the 3D eyewear will receive the other IR signal.

3D Sources

3D Blu-ray Player, Satellite, Cable, and Over the Air Signal.

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).
