Default Plasma in the news

I had heard some rumors over the last few months that LG might curtail PDP production, LCD's coming down and all.
Here is a message from Twice that speaks to an expanded role in PDP panel production.

By Greg Tarr -- TWICE, 7/2/2007 11:22:00 AM

Englewood Cliffs, N.J. LG Electronics initiated today a new panel production process on its A3 plasma display panel (PDP) line in Gumi, South Korea that will produce eight panels instead of six from one sheet of glass substrate.

The process, which LG calls its 8-up technique, is said to maximize LGs PDP production capacity by stretching the number of panels from a single glass substrate.

To accommodate increasing demand for plasma display panels, LG will maximize its production efficiency, especially in the second half of the year, said Simon Kang, LG Electronics Digital Display Co. CEO. This is part of our ongoing campaign to streamline our production system.

The improved eight-up processing will increase LGs total capacity per month by 22 percent, from 360,000 to 440,000 panels, greater than the total capacity before the outdated A1 line was shut down, the company said.

LG said its strategy to raise efficiency entails increasing per-line capacity while closing older, less efficient lines. In addition, glass substrate sheets used for LGs eight-up PDP production will be increased to 77 inches by 86.6 inches in size, compared with glass sheets of 77 by 64.9 inches size used for six-up processing.

LG said it also began mass production of 50-inch plasma Full HD (1080p) high-definition TVs last week as part of its ongoing efforts to focus on premium display products.

According to DisplaySearch, demand for plasma display panels is expected to continue to increase in 2007, from 2.3 million in the first quarter to 2.7 million in the second quarter, 3.2 million in the third quarter and 4 million in the fourth quarter.

Does a 3 July article trump one from 2 July?

Here is a quote from a 3 July article:

"LG Electronics, the world's second-largest PDP maker after Matsushita, is struggling to reduce heavy losses at its PDP business. Recently, LG quietly halted production at one of its three domestic PDP lines as part of a restructuring." http://www.ft.com/cms/s/65271626-28f...b5df10621.html

And another from June.

"If the trend accelerates and all the PDP manufacturers begin beefing up their production stances, PDPs could take back the leading position. But Pioneer is treading water, Hitachi has decided to put off the decision on construction of a new factory until fiscal 2008, Funai Electric Co. has gotten out of plasma TVs altogether, and LG Electronics is closing inefficient PDP lines. So that leaves only Matsushita as the main leader so far." http://displaydaily.com/2007/06/01/p...are-from-lcds/

Yea, I know. Go figure. Looks as if LG - after a house cleaning - along with Matsushita - may be part of a small group intent to make a go with PDP.

Personally I like PDP, but I do question how long it will be before LCD kills it off. The inaccuracies about PDP still are out there in abundance, and most salespeople on floors take the easiest route - which is to sell the LCD. Be interesting to see how all this plays out.

Despite Plasma strengths, will it overcome it's major drawbacks? Using enormous power - generates a lot of heat and fragile to move around?

Plasma will always have a place. Size isnt everything....there are things like color and black levels that lcd cant touch, no matter how big an lcd you make.

I believe PDPs will have a place but they may well become a niche product.

Color is subjective. Yes, I know you can measure color purity. How many do that? Each individual has their own scale when judging color. There are fans in both camps who swear that colors are better on their side. It is a matter of opinion.

Black levels are not completely in the PDP camp. Nor do they convey the whole story. A Sony XBR2 has a better measured black level than a Pioneer Pro FH1. The deepest blacks ever measured would be wasted if a display has poor gray scale tracking. Without proper gray scale tracking, blacks (and whites) could be crushed, hue could be off, etc.

That gap is closing as LCD becomes the worlds choice of FPD. This will mean more research into image creation. Don't be surprised if eventually LCD becomes the defacto standard for FPD's.

I'm sure that will ultimately happen, as LCD's are cheaper and easier to manufacture than Plasma displays and you can make just about any size LCD you want once the process is tweaked and the yield is good.

Not many people are going to care if a 60" Plasma looks better than a 60" LCD that costs half as much.

On the other hand, the cost of Plasma displays can also be reduced with process and yield improvements and IMHO, a light *generating* display like Plasma will always look better than a light *filtering* display like LCD. If they can keep Plasma displays within 30% of the price of equal-size LCD's, I think they can still sell enough to be a viable niche business.

Most computer graphics people enjoy LCD's and those who liked the CRT picture will like a plasma. But where is this measured black level that the XBR2 beat the PROFHD1? Are you speaking of contrast ratio? Have you ever seen them side by side w/ a dark seen and really believed that the XBR2/3 or any LCD could compete w/ the black level of the PROFHD1 or any Pioneer/Panasonic plasma for that matter.

1. Contrast ratio is a joke...specs. are the worst way to judge a product...Unfortunately it's all we have.

2. The eyes will always tell the truth.

3. Everyone will like what they like, to each his own I always say.

I would like to someone like D6500K so a side by side comparison of a major plasma panal and a top LCD to see what the differences in color readings would be and how close they calibrate to each other...
it may be helpful information for all of us...

hey D6500K you listening?.....

Seems marketing is winning over picture quality.

Yeah I want to choose a technology (plasma) where the "NBC" or "BBC" or similar logos get burned-in the corner of my screen!

Not.

Frak that. Plasma sucks. I HATE burn-in, and I can't believe anybody would say a burn-in prone piece of excrement likle plasma is "better"

My, my, we have a narrow world-view, don't we?

The solution is to not watch the junk that's on television or the junk from a video game (There, how's that for a mature world view?).

Seriously, it's easy to avoid burn-in with Plasma displays (and CRT's) and for watching movies nothing looks better to me.

IMHO, even the best LCD's look grainier, look less sharp on moving images, have inferior color saturation, have inferior black levels and contrast when viewed off axis and have backlight bleed-through off-axis.

I can't imagine me buying an LCD until a few more product generations have passed. To me, buying a display with what, to my tastes, is an inferior picture just to avoid burn-in is silly. It's like buying a Toyota Camry instead of a Porsche 911 Turbo because you're afraid you'll tear the air dam off the front of the Porsche if you hit a pothole. Some people will buy the Camry, and that's fine, but it's ridiculous for the person who's afraid of damaging the Porsche to disparage the Porsche or the person who buys one.

Well, I agree with you that even the best LCD's don't equal plasmas in picture quality. Unfortunately, I disagree regarding burn-in. This comes from personal experience. My own 3 month old Pioneer Elite Pro 940HD now has burn in, in spite of my following all the precautions to the letter. Brightness and contrast kept down. Screen mode in its lowest power setting. Full screen images only. Vary programs No games. In spite of all of this, there's noticeable darkening of the screen in the middle and at the bottom. Bottom right logo burn in as well. Looking at a white screen is depressing. Yes, I watch the news for a couple hours a day, and some network programs. But this is a TV, and a TV shouldn't be damaged from watching TV programs. I guess the plasma manufacturers rely on people not noticing these problems-they are most visible on bright backgrounds. Maybe I'm just critical. But now that I've noticed the problem, I can't ignore it. Yes, it isn't terrible on normal video images, but it's definitely there. I'm going to run JScreenfix to see if I can wipe some of the problem, but I'm doubtful. I'm absolutely delighted with the picture quality on this set, but I can't believe the manufacturers have the gall to claim that burn in isn't an issue in plasma sets. Now I'm stuck. I guess I'll have to downgrade my picture quality in the interest of having a tv that doesn't get damaged by watching it. My dealer service advisor came today and agrees with me. He says the dealer will give me full credit towards whatever I want. What to do?
