I'm a bit confused here. Going through a few other forums, there were some recent commets on the SONY GWIII.


Comments such as: 3rd generation LCD and it's their latest LCOS set.


The LCOS identification was in several threads and it baffled me.


I read this on Agoraquest.


Any idea why that is being promoted?

The GWIII line is not based on LCOS -- it uses transmissive LCD imagers. In short, the image you see is formed by passing light through LCD imaging chips.


LCOS is a reflective technology. Images are formed by reflecting light off of the LCOS imaging chips. LCOS is also based on liquid crystals, but it is a different technology than transmissive LCD.


AFAIK, there is only two currently available RPTVs based on LCOS: the Mitsubishi Alpha, which uses three LCOS imagers (one for each primary color), has an 82" screen, and runs about $20K or so; and the Philips Cineos line, which uses a single LCOS imager and is in the same price range as the Sony GWIIIs and Samsung DLPs.


Toshiba used to have an LCOS-based RPTV, but had significant problems with imaging chip failures, and took the line out of production. Reports are that the imaging chips in virtually all of these sets have failed and Toshiba has given refunds or replacements to the purchasers.


JVC is set to introduce a line of LCOS-based RPTVS in Q3 of this year. This is good news if you're an LCOS-o-phile, as JVC has perhaps the most experience (and success) with LCOS in production systems. They have produced LCOS-based front projectors for several years now, and these seem to be very stable and very highly regarded.


Several other manufactures are allegedly jumping on the LCOS bandwagon. If you're interested, check out this page created by Arun Gupta for more information. Also, there have been several threads on LCOS in this forum.

The JVC LCoS sets will also use a three-chip imaging device - unlike the Philips Cineos line which uses a single chip design. This will eliminate the need for a color wheel and the potential "rainbow" effect which is a problem for many people.

The biggest story about Lcos is Intel's development of a new

generation of Lcos chips, which they claim may result in a $2000

big screen set in 2005. If they succeed, I have no doubt that Lcos will

dominate the entire market - plasma, DLPs, everthing out there. It has

several advantages in terms of manufacturing efficiency and PQ and

should be more reliable. It could also be user serviceable for the major components, and even user-upgradeable if they design the chips as

they have PC processors in the past. It's far and away the most exciting new technology working its way forward - most of the other technologies

seem pretty much at the end of the road, development-wise.

I'd add that JVC calls their LCOS technology 'D-ILA', and Sony calls theirs 'SXRD'. Don't ask me what it all stands for.


Sony came out with a high end front projector LCOS unit, and may do rear projection LCOS in their high end lines in the future, but have none currently.

This thread should be "frozen" right now and memorialized as the perfect example of this forum at work clearing up misunderstandings.

I find JVC's story much bigger than Intel's.


Intel has no OEMs yet and no products.


Even Sony has a super-expensive projector and has hinted at RPTVs.


Then there is second-generation stuff from Philips.


And the prototypes shown by eLCOS.


Intel's designs are not going to be field upgradeable with new components. That's ludicrous. And until they announce something specific, it's nothing more than hype.


Oh, and projection is not going to eliminate flat panel from the market. That's silliness.


Finally, D-ILA = digitial image light amplification. SXRD = Silicon Crystal (Xtal) Reflective Display (I think that's the D).


They are both liquid crystal on silicon, but are not precisely the same. They do it differently and have some different characteristics.

My understanding of the SXRD is that we may see an RPTV in '05, but it will have the Qualia badge - read very expensive - initially. Too bad. I'll have my 1080p Samsung by then! Not waiting that long!

I disagree.


Sony will make it very very expensive.

I've been away from the forum for awhile now. Can anyone tell me when JVC's Dila (LCoS) sets are due to be released? And at what price range for these sets?

 

[rolypoly]

JVC units:


HD-52Z575 - 52-inch HDTV monitor, 1280 x 720, 1000:1, $4,500 MSRP

HD-52Z775 - 52-inch iHDTV, 1280 x 720, 1000:1, $5,000 MSRP

HD-61Z575 - 61-inch, HDTV monitor, 1280 x 720, 1000:1, $5,500 MSRP

HD-61Z775 - 61-inch, iHDTV, 1280 x 720, 1000:1, $6,000 MSRP


From SID, JVC claimed these units will be out in [/edited] end of [/edited] Q3.

I am in the market of 50WE610. How do I know if the model is GWIII? how long is the life of the bulb?


Thanks

VP

 

[Hughmc]

The chips in the GWIII are made of ?


Silicon.


The display type is?


LCD: Liquid Crystal Display


GWIII is actually, not intentionally, misrepresented by Sony as it is a Liquid Crystal on Silicon.

WE610 = GWIII (3rd generation Grand Wega).


Bulb life has been long for many, VERY short for some. Some have blown their bulbs within a couple weeks of purchase. Supposedly the bulb issues are resolved, but we're going WAY off topic so I'll stop there.

Word games aside. The Sony GWIII does not use the LCOS technology.

As for part 1, you have it backwards. LCoS designs are notorious for their low production yields - which is perhaps the largest of the many reasons that LCoS based PJs and RPTVs haven't dominated the market thus far. Each new player into the market (most recently Sony - by new I mean shipping a product) claims to have solved the yield issue with LCoS. None seems to have done so completely though obviously strides are being made. That said, one thing they do not offer is relative manufacturing efficiencies.


As for part 2, not sure if you're up on the recent 'x' line of DLP chips from TI, but development wise it's both a fascinating, out of the box solution to a problem, and, IMO, proves that DLP has a long way to go on the path of improvements. Further, TI's recent cinema class PJs are outstanding and show what the technology is capable of. Don't get me wrong - I love LCoS for its strengths, but it's not the only game in town. This race is just heating up IMO.

Sony's LCD imagers are not silicon chips in >>any

I saw the Sony Qualia F Projector and I'm still trying to reattach my jaw
