DLP or LCoS ?

Beside the prices of the projectors, what do you think is the better technology considering 3 panels DLP or 3 panels LCoS? I would like to hear the opinion from people that have seen projectors using these technologies. DLP or LCoS?

First a 3 chip 1080 DLP will cost at least 4x what a LCoS will.

They are both so different. I don't think there is a clearcut winner. But, specifically to your question, 3 chip 1080p DLP is big bucks. But, it is the ONLY option if you want a big screen. I am doing one on a 17' wide screen right now. If you aren't going with a large screen, then there is not as much benefit to the 3 chip DLP and it is likely overkill.

I think this dlp vs lcos will be very influenced by which technology is best adapted to laser illumination.


I would bet lcos if we are talking 2000 ANSI lumen or less.

With greater than 2000 ANSI lumen it might be dlp.

Great bottom line synopsis. :)

A few years back there used to be clear cut winners. With the advent of 1080p machines there's more likely just preferences. Even when it comes to LCD they are all amazing machines. It also depends on your viewing distance when under 1920 x 1080 resolution. Outside 2 screen widths about the only thing you can tell the difference is brightness and contrast. For 1080p machines the lines probably blur around 1.5 screen widths

My belief is that people need to see the different technologies in person. They do have different looks. To one person, DLP will look better. To someone else, LCoS will look better. To my eye, DLP looks more vibrant than LCoS. Other people just as strongly prefer LCoS. Before anyone spends thousands of dollars on a projector, I would strongly suggest that they take the time to go look at a few of the candidates and see what looks best to their eyes.

The answer to DLP or LCoS at 1080p is a clear cut...


YES ;)

What home can tolerate that size screen? You must be doing a commercial project, no?

Perhaps a new level is starting to emerge, Mansion cinema.

Diplomatic aren't I? I should go into politics with my vague answer. :) I do speak the truth though.


Not a commerical job...it's a house. He always wanted a huge theater, and that is what he is going to get! :)

Tolerate would not be the word I'd use. :D

I should clarify 17' wide 2.35:1 system. 18 chairs, etc...

Well, there is the Sony 4K . . .

Tough question. I prefer LCOS, but then again I have never had a 3 chip DLP in my home so its not a fair comparison.

Very true, and the QXC1 from JVC. But those are in an unheard of price range. :)


I get a lot of people asking if 3 chip DLP is better than the other technologies. I usually answer, not necessarily. They are really geared towards larger screens. In other words, if someone wanted a 100" screen, generally 3 chip DLP is overkill and often can be too bright for such screens. Of course this is not always the case as some have ambient light issues, etc...

"...Outside 2 screen widths about the only thing you can tell the difference is brightness and contrast."

That's correct Tryg, but at the size of normal home theaters the brightness and contrast of dlp and LCoS are similar, or maybe is better to say that the LCos would have the necessary luminance.


"I would bet lcos if we are talking 2000 ANSI lumen or less.

With greater than 2000 ANSI lumen it might be dlp. "


Ohlson, that means that for home theaters, not the 17' size, the LCoS is the technology to choose.


But what is so different with these two technologies that we have to agree both are good, and that is something that we can measure, but still they look so different for your eyes?. Joe Linn's opinion: "To my eye, DLP looks more vibrant than LCoS"


In the past, when we make comparisons, nothing compares with the contrast of dlp (beside crt, of course),but LCoS contrast is very good, even without the active iris, and the price of projectors using this technology is going down. I haven't seen the new Sony pearl that use uhp lamp but for the review that cine4home did, I can see it is excellent. I have seen the ruby with the xenon lamp.


DLP technology is made only by TI, as far as I know, but it looks that LCoS is going to be made by different companies, and if fabricated in large volumes the price could be going down.


From Insight Media: "Syntax-Brillian announced that it has received an order to supply 15,000 sets of LCoS imagers to Sino-Brillian Display Technology Corp. Production at Sino-Brillian will ramp to ramp to 300,000 units annually."


The point is that if it is so difficult to say which of these technologies, even comparing with 3dlp which is expensive, is the better and with the price of the 3 LCoS going down, TI will have to do something better than a color wheel and 1 dlp. LCoS is clearly a better contender than LCD for home theaters.

To stay coompetitive I think lcos has to improve in the direction that HD-NEW from JVC is moving towards, 10000:1 native and 350:1 ANSI contrast.

I expect Sony to move sxrd into this territory as well in 2007. The 0.61 panels will need a replacement in 2007.

Laser illumination will improva MTF at high spatial frequncies for lcos. I think this will give lcos more punch.

It is anybodys guess when laser illumination is ready.

Other than Lasers, anyone want to guess where LCOS is headed after the Pearl and JVC-NEW projectors? My guess is that if JVC is able to hit 10k:1 with new off the shelf polarizers, that Sony will also incorporate these into their next projector (assuming that the polarizers aren't proprietary to JVC). It's logical to assume that at next years CEDIA that Sony will be showing a Pearl with 10,000:1 native CR but with a DI and claims of 30,000:1 on/off CR :eek: All with a price below $5k. :eek: :eek:

Sony did some improvements to the optical block of their HS51A/60 LCD (colored? polarizers and plates) which increased CR ~ 2X. It will be interesting to see if those changes could be incorporated into the next gen SXRd products.
