(1024x1024)



Plasma WEGA vs CRT TV

• Life Span– Approximately equivalent to CRT

– Life span of any display is very dependant onuse!

• No image flicker

– PDP technology doesn’t scan like CRT technology

• No image distortion caused by magnets.



As of Jan. 2002

Plasma WEGA

• Built to be a television product vs a monitor!– TV Tuner

– Stereo Speakers– Composite, S-Video and Component Video

• Flexible placement– Table Top Stand (included)

• Picture performance is optimized for video andfilm based content– Skin tones will be more natural and beautiful.



As of Jan. 2002

Plasma WEGA vs other PDPproducts

• Ready to go out of the box!– “All-in-One” Solution

– No separate components (i.e. NTSC tuner, speakers, etc)

• Occupies less space!– Tuner and Speakers are built-it

– Additional components takes up additional space.

• Best picture performance regardless of source.– Competition may only optimize DVD content but not HD or

vice versa.

– Skin tones are more natural and beautiful.



Sony Video Features

• *Digital Pixel Generator

• Pixel-by-Pixel I/P Conversion

• CineMotion Full Reverse 3:2 Conversion

• *Uniscan Scaling Technology



Digital Pixel Generator (Digital Processing)

• A Real Digital System– Incorporates Sony-unique digital signal

processing technologies.– All signals are directly transmitted andprocessed digitally.

– Eliminates picture degradation!

• Maximizes display performance of high endvideo sources for natural, rich imagereproduction especially high-definitionsources.

Pixel-by-pixel I/P Conversion

• Constructs a film or video scene one pixel at a time!

• Executes rapid transitions for film based content

with mixed characteristics.• Reduction of motion artifacts associated with

video based content.– 3 Modes vs. 2 Modes of video based I/P conversion.

• Benefit:

– Fluid, lifelike motion along with breathtakingimage detail.



Pixel by Pixel Film Based I/P Conversion

• System provides rapid transition betweenFilm Mode and Video Mode on any pixel ina field of video.

Video Based I/P Conversion• Conventional LSI

– 2 Modes for Video based content• Still and Motion only!

• Sony’s “Pixel by Pixel” I/P Conversion LSI– 3 Modes for Video based content

• Still, Motion and Slow Motion

– System instantly switches its operation from

Still, Motion or Slow Motion at any pixel in afield of video.

• Benefit:• Enhanced reduction of motion artifacts regardless

of movement in video frames.

Questions?

• Q1: What is the life span of plasma displays?– A1:Plasma displays are equivalent to CRT based. The life

expectancy of any display product is highly dependent oncustomer usage.

• Q2: What is the “browning effect?”– A2: What is being described is a loss of brightness over time

thus creating a brown or yellowish effect in the picture.

Currently, there is not a set standard to determine when thiswill happen. There are two reasons why it is difficult. First,product usage will vary among owners thus effecting when theplasma panel starts to dim. Secondly, each manufacturerutilizes different ingredients to make phosphors. Somanufacturers will vary as well.



Questions?

• Q3: Does Sony make its own panels?– A3: We manufacture the television product but do outsource

various components. The panel is only one component of PlasmaWEGA. Sony engineers spend a lot of time and resources toimprove the overall performance of the product’s experiencefor the consumer.

• Q4: What type of image am I seeing? Is it progressive or

interlace?– A4: With plasma displays, video signals are no longer scanned

directly to the panel. Sony’s *Digital Pixel Generator takes afull frame of video, regardless of format, and illuminates theappropriate pixels that make up the panel.



Questions?

• Q5: Is it true that as pixels burn out, theremaining pixels compensate? Will this have an

effect on the products life span?– A5: The failure of a pixel may be a malfunction of

components or wire damage. Each cell on a plasma panelisn’t seal from one another. So, if a dead pixel is next toa functioning pixel, the gas from the functioning pixel

may flow into the adjacent pixel. Therefore, giving theillusion that one pixel is doing the job of two.

W h a t i s P L AS M A?




Kyushu FHP Limited started the operation in July’99as a manufacturing subsidiary wholly owned by FujitsuHitachi Plasma Display Limited which was jointly

established by Fujitsu Limited and Hitachi Limited todevelop, manufacture, and sell plasma display panels

which are widely noticed as large-scale display devicesfor upcoming age. In the advent of the new generationcharacterized by large, thin television sets and digitalbroadcasting, Kyushu FHP will meet customer needs.

What is the ALIS Method?

FHP is going to produce mainly PDP home TV set of type 32, and 42by completely adopting the ALIS Method developed by Fujitsu.

Features of the ALIS Method:

- The display appears with as high a degree of minuteness as the

one produced by the traditional (VGA) method.-(HDTV can be accommodated without enlarging the circuit scale!)

-It utilizes all spaces between electrodes for light-emitting.

(It improves the brightness through high rate apertureefficiency)





ALIS Method Display :

-The light-emitting feature of the ALIS method is displayedusing a time division system. The display lines of an odd number

and those of an even number are displayed in turn at a highspeed.

-With the help of ‘persistence-of-vision’ in the human eye, vividand images can be seen.
