Is D-ILA and LCOS a dead technology?

[LittleKing]

It seems like I've been hearing about several companies moving away from this technology. It only seems that only JVC is the only one persuing this tech right now. So my question is are D-ILA and/or LCOS not what people or companies thought it was going to be? Are they not reliable or just to much competition?

As many people here, my wife and I are looking to get a new HDTV. If JVC's D-ILA tech will be around for a while and if it reliable then we will probably go that direction as we both like that tech. Otherwise we'll probably end up with a DLP HDTV.

What do you all have to say?

Thanks,
LK

I think that you should get a TV that you like the looks of. All technology will eventually be replaced by something cheaper, better, or cooler and the main thing is that if you get a JVC, then they are likely going to at least be around for a while to service it should service be needed.

But really, in the 5 or 6 TVs I have owned, I've never taken one in for service. So why worry about whether it'll be around tomorrow when it is around today?

I personally am not a huge fan of LCOS or D-ILA, as they really don't seem to boast video levels as high as the current LCD & DLP projectors. I just looked at the newest Sony LCD projector next to a JVC and the Sony was far brighter, had a larger viewing angle, and handled shadow details much better than the set right next to it.

LCD, DLP, LCOS, or D-ILA... As long as you are happy.

Hmmm?

The Sony must be extremely bright! I have yet to see a TV that compares in brightness of the JVC (not necessarily a good thing). In fact a couple of months ago in HT magazine they said that if the JVC was small enough it could be used as a flashlight it was so bright.

I agree however that what ever way you go they all are great compared to analog sets. I think if I had to rank the different technologies I would say I like the JVC HD-ILA, then Lcos, DLP, LCD.

The main problem with Lcos (HD-ILA) is the the cost to manufacture the chip is too expensive. So its not really a quality issue, these companies don't seem to think they can make huge profit off this technology. So Philips decided to move in a different direction.

Actually, this might be a good chance to pick up a Philips Lcos set for a great price. I know our price dropped recently.

Have your ever owned a crt based RPTV? They are not nearly as reliable as a traditional CRT which may or may not apply to DLP or other chip RPTV's. But the chip sets haven't been around for 20 years yet so who knows how long they are going to last.

I'm not so sure about that. Everything I've read says the opposite. The chips are (or were thought to be) inexpensive to make and cheaper than DLP. That's why Intel was boasting $2,000 sets with their new chips. But Intel couldn't produce the technology due to manufacturing issues (which of course would drive the cost up). This is the same reason why the initial LCoS lets from Toshiba and others were delayed for many months. The promise with LCoS has always been a better picture than DLP for less money. But the manufacturers have not been able to deliver on that promise.

After all the Rear projection CRT TVs I have seen with convergence problems out of the box, I swore I would never own one not matter how cheap they get.

I agree most of these technologies have not been around long enough to know what to expect.

I have first hand experience with that. I own a Toshiba 56H80. It has a great picture but I've never been happy with the convergence. It seems no matter what I do it drifts almost immediately. IMO the only CRT RPTV to consider is a Mitsubishi. They've been doing it a long time and seem to have the least problems with convergence.

When Pioneer made rear projections they were very nice. They never had any convergence problems. I was really dissappointed to hear they stopped making them.
