View Full Version : DLP and Sony Response to dla-RS1
It appears that a new standard had been set with the RS1.
Competition never rests. There will be reactions. What will it be and when will we see it? How long will JVC be king of the hill?
Any predictions?
Andrikos 02-12-07, 01:55 PM My feeling is that now that we're "done" with resolution increases (for the vast majority of HT market) the focus will shift to LAMPS.
It is my feeling that lamp projectors are singing their swan songs (again for the HT market) and that LEDs will be the MAJOR upgrade.
The thinking is that we will now go from "passive" illumination devices to "active".
LEDs are switchable, so a bank of 3 (RGB) LED arrays will actively benefit contrast and 3-dimensionality of the picture.
DIs will be a thing of the past and so will colorwheels.
LEDs will benefit all technologies but they will mostly benefit 1-DLP as they automatically increase the luminous efficiency of the 1-DLP system.
As you can see from my sig, i'm excited about this prospect.
Hopefully it will happen by 2009.
Dlp already has Sharp z20000.
The big question is what Sony will do next with sxrd.

The Sharp 20000 isn't a response. Half the native on/off and a color wheel. Thats not a response. :p

The Sharp also has over 2 times the ANSI C/R and was here before the RS1, so it is not a response. I think I could be happy with either of these, but the RS1 is cheaper.

I am dissapointed with no mention of LASER.:)
I still think Laser will hit the market before LED. A lot of issues to overcome before LED hits the pj market. Of course, large and inexpensive flat panels should be here by the end of the decade.:)

I hear ya. Cheaper is where its at! I assume rainbow/headaces are not an issue for u.
I recently was at a BB and previewed an older sharp DLP (not sure which model, I think it was the 10000). When I left the store, not only did I have a bad headace but my stomach started to churn. The Sharp 20k could have 10x the ANSI CR and be less than half the price of the JVC. I still wouldn't/couldn't consider it. I know allot of people do not have this problem, but its something to be considered.

Perhaps I think I know something about the future....

According to my Sony contact, unfortunately for us AVSers Sony is not as concerned about the HD1/RS1 as we are. The seem more focused on having a ~$3K MSRP Pearl level product by CEDIA. Their true next gen product will be at a > Ruby price point.
Mojo_LA 02-12-07, 06:13 PM Philips recently announced it's new line of high power leds (calls Lumaleds) that are 500 LUMENS.
I think we're getting closer to LED projector lamps much sooner than anyone anticipated...

Will this simply be a reduced MSRP Pearl, or a totaly new projector?

Makes perfect sense. The R&D that went into Qualia/Ruby/Pearl is amortized and can be used to design a profitable higher volume projector in the $3K range. Remember Qualia was $30K, Ruby was $10K and Pearl is $5K. Sony will probably look to design another "statement" projector. Exciting times.
Andrikos 02-12-07, 06:27 PM Another thing that people need to consider is thermodynamics and light efficiency:
A UHP lamp (like all lamps) spews light in a (relatively) flat band of frequencies.
A UHP lamp will be several THOUSAND lumens inside the projector before it turns into a D65 candle light on the screen.
We ONLY need 3 specific frequencies (or a narrow band of them) in RED, GREEN and BLUE.
We all know that UHP lamps are RED deficient so in order to get D65 out of them, G and B are further lowered along with all the other frequencies notched out.
All this WASTE light is turned into heat which needs to be removed in order for the electronics to function and have a reasonable lifetime.
That means elaborate and EXPENSIVE heatsinks (Qualia, Ruby etc.) or loud fans or a combination of both.
This prevents from having a compact design (important for portable apps) and lowers the lifetime of the projector (power supply failures, fan failures etc).
In the case of RGB LEDs, we don't have any excess frequency content therefore we don't need as much cooling which will allow for more compact designs, quieter projectors etc.
We may end up with the same "1,000" lumens on the screen but we have way less lumens inside the projector with LEDs.
And I'm not even considering the likely higher luminous efficiency that LEDs will offer one day (>100lm/W) compared to their UHP competition.
I don't know of native LEDs that throw EXACTLY the right frequency without filtering. Normal LEDs are filtered too, so they have some wastage in color filtering just like other light sources. Of course, the amount of waste should be much less, but it's not like they're currently perfectly tuned for HT requirements of R, G and B. Maybe in the future.
Bottom line, even with all the advantages LEDs could have, manufacturers are having a hard time making 300 usable lumens come out of a LED FP, otherwise people would buying them now.
Digital2004 02-12-07, 09:42 PM DLP in mono chip still suffers from unclean picture at close viewing. mainly static and motion dithering. it will never disappear, rainbows is just the visible part to the public but dithering is a problem and causes fatigue in some (many) people. some pjs are better than others at reducing this but it's there.
DILA technology doesnt add noise (to simplify). sure there's the artificial pop effect of some DLPs but in real life, it's all about massive infinite resolution, cleanness and massive native contrast ratio as CRT had without the iris brigtness compression.
things change. 3DLP is nice :D but still pricey....

LED projectors are in the market. Just not the kind you may buy.

romanesq 02-13-07, 12:13 AM I refuse to downplay my Pearl until SED is available. And I want 50,000 lamp hours and a lifetime warranty and also in home service and immediate same day swap.
Okay, I'm plenty happy with the developments in the last couple of year and hope that Sony along with others will continue to push the envelope.
It's good enough for me. And guess it's time to almost welcome the JVC vaporware to the market. But it still hasn't hit the US market so it's a bit premature to sing its praises over the Pearl among others.
Frank Derks 02-13-07, 09:26 AM The major advance in the JVC is the re-designed optical path.
The wire grid polarizers are really innovative. The improved lcos chip is just an evolutoinary enhancement.
It will take some time for the others to catch up.

THe Wire Grids were done by a 3rd party, and is not JVC exclusive IP They have been around since at least '02. There were still some concerns around light efficiency and durability/longevity vs. the prior block design.
LED's would be a nice way to bring down the power consumption and heat. Home Theatre projectors have the potential to remain minimal power consuming devices. Also, less heat inside the projector would help keep parts uniform and less liable to deform or wear-out prematurely.

Didn't say it's a JVC exclusive IP. They got it to function in this new projector design. Light efficiency seems adequate enough. They had light to spare for additional color filtering to get better primary colors.
For LCOS it's a major step forwards.
Next advance for (3 Chip) DLP should be the elimination of the dithering effect (Tough nut to crack) and to marry the sharpness and pop with a more natural looking image.
noah katz 02-13-07, 03:52 PM "G and B are further lowered along with all the other frequencies notched out. "
I don't believe much notching is occurring; a broad band in the right part of the spectrum is used and works pretty well.
Our eyes' three sets of cones are also broadband in their respective parts of the spectrum.
