While some may have balked at Sony taking an
early exit from the PDP market, LG is becoming the fourth major player to reevaluate its investment in plasma after
Philips was caught claiming that LCD TVs would likely shape its strategy and Hitachi began to look intently
overseas for buyers. Reportedly, LG is closing the doors of its oldest
plasma manufacturing plant in Gumi, South Korea as it hopes to "increase operational efficiency and reduce costs." The removal of the A1 plant will drop its plasma capacity from 430,000 to 360,000 panels this year, and it should save the company somewhere between "$22 million and $32 million per year." Notably, LG currently sits in second place in quantity of PDPs shipped worldwide, but considering the perpetual
nosedive of HDTV
prices over the past year or so, we can't say that
Life looks too Good in the PDP arena right now.

It's because DLP is much beter technology and cheaper it has killed Plasma tv sales since it was released. All you gotta do is replace the light bulb and it's as good as new and never burns in. Plasma is the worst tech with burn in and once the gas wears out the tv is dead. Also DLP is MUCH cheaper my 71" DLP is only like $4500 (seeing how i work at best buy i get it on discount, the new HL-T7288W looks awesome saying it has this new plug to make video games and movies in 3D look it up on samsung's website). I am getting my HLR set replaced with the HLT when it is released.
The reason why plasma was so popular was because it was the first but not the best no more.
Personally, I think rear projection LCD is the best HD bang for the buck. I've seen DLP screens and I'm no fan. Rear projection costs are lower as well. I know this is sort of like arguing religion..so I don't intend to start a highly technical flame war here. Let me add the biggest factor in choosing rear projection LCD. Price. Technology is disposable. So who cares if your $1500 rear projection is only slightly worse than a DLP, flat LCD or Plasma? In 5 years I can buy the latest technology again which at the bottom of the price spectrum will be better than anything at the top end these days.
Plasmas can burn in...but it takes a lot longer than it used to(12 hours or so generally if your settings aren't horrible). Even if you do burn in the plasma you can get rid of it by whitewashing it. Also, the halflife of the gas is 60,000 hours which is more than most will ever use it the display.
I have a DLP projector and I love it, but I'm no longer a big fan of rear projection displays. Yeah they're a great value, but I absolutely hate the Silk Screen Effect. I can see it on any DLP, SXRD/LCoS, or LCD RP display.
Also good plasmas like Pioneers or Panasonics have even better black levels than DLPs and some LCoS displays. We all know how important black level is, it really makes a good image stand out
I'm not a fan of LCD, their black levels are still not at the level of DLP, LCoS, or plasmas and it really hurts the image imo.
Quote from above - "I think rear projection LCD is the best HD bang for the buck".
Well, I disagree, and think it's the worst HD bang for your buck. While SXRD LCoS (a form of LCD) is somewhat acceptable, both have problems with a blurring image in fast moving scenes or sports, same as flat panel LCDs. It doesn't matter the "pixel response rate", as the blurry effect is inherent to LCD technology (especially).
DLP is a better technology (with excellent black levels also, unlike LCD), but can also have some blurring if you sit too close. New LED-light based models from Samsung (slim design, 1080p resolution) are also quite an improvement in the DLP category!
The best image technology (other than classic CRT displays) is PLASMA, with deep black levels and no pixel image blurring on fast moving scenes or sports.
I'm a Sharp Aquos LCD owner (since '05), and while I've appreciated my set the last few years, I clearly can see the improvement and better quality that plasma displys provide, and will be upgrading to a larger plasma by the fall, either a model from Panasonic, Pioneer, or Samsung - probably Pioneer since they are the best, but also have the highest price tag.
Actually LCoS is not a form of LCD, I think of it as a cross between LCD and DLP. It uses mirrors, liquid crystal, and it rotates polarizes light. LCoS and most current LCDs(or even those a few years old) don't have any ghosting issues either
"ghosting issues" - well, that depends on your understanding of just what those words mean.
If you're talking about the "light trails" (of older LCD sets) on fast movement images, then yes today's LCD and SXRD (LCoS) models don't suffer this effect.
But what I'm referring to is the natural BLURRING effect that is inherent to LCD technology (which you can explore furthur on various websites - Sharp even has a technical paper about it), which is always present on faster moving images, especially noticeable with sports, like basketball.
How it effects a particular viewer's eyes/brain is another matter; some don't have a problem with it, while others notice it immediately, and some complain it gives a slight headache or even worse: eye fatigue, etc.
It's really noticeable in a darker room environment, and if you had a plasma next to an LCD you would easily notice the onging blurring effect on the LCD that's not present on the plasma.
JVC and SONY will have newly redisigned flat panel LCDs this summer/fall, featuring 120hz signal processing to help reduce the blurring (compared to the normal 60hz processing of current LCD sets). Samsung and Sharp will also offer newere LCD displays with the 120hz feature.
LCD - liquid crystal
SXRD - liguid crystal on silicon (LCoS)
...so SXRD is a form of LCD technology, but obviously not the same [to clarify your other comment above].
Actually LCos IS a form of LCD, it is a lcd screen with a mirror attached on the backside. It is a traditional LCD display except that it reflects light back as it passes through it and hits the mirror. Therefore, LCos is reflective and traditional LCD is transmissive. It is not a combination of DLP and LCD. DLP uses little micro mirrors that can be flipped and a color wheel. LCos does not have mirrors that flip and no color wheel. Think of LCos as a stained class window with a mirror backing. LCos and LCD cannont reproduce blacks as well as DLP by themselves a dynamic iris must be used. All current technologies today are tradeoffs and no one is the best. Your choice depends on the room application, primary use and budget.

Interesting. I will look into it more as I haven't heard or noticed it...yet. btw Sharp already has 120Hz LCDs for sale
"SXRD - liguid crystal on silicon (LCoS)"
SXRD(Silicon X-Tal Reflective Display) is based on LCoS but it isn't exactly the same(as is true with JVC's HD-ILA).

Yes LCoS displays use liquid crystal but that's about all they have in common. They also use mirrors like a DLP does but also in a different fashion as you've stated. That's why I say LCoS is a mix of DLP and LCD...it uses both mirrors and liquid crystal. It's all about perspective I suppose
The biggest difference of LCoS vs LCD and DLP is how it varies the level of each color. Light is first polarized and then split into red, green, blue. When the light then reflects off the mirrors and passes backthrough the layer of liquid crystal, a current is applied at the specific pixel and rotates the light some amount. The light is then again polarized before it is display, by polarizing the light again it will become dimmer based on how much the light was previously rotated. That's the heart of how LCoS works.
Nice LCoS displays have the better black levels compared to DLP or LCD. In fact they're beginning to replace the use of CRTs in professional uses. ExtremeTech has an excellent article about LCoS if you care to read more.
