So, whats stopping JVC from launching say a 0,75 inch 2160p panel today?
Is the difference that the 2009 8K panel was analog Control d-ila and today it is digital?
If so why is that harder?

Next on the agenda must be a laser d-ila light Engine. Will that allow JVC to use smaller lens with high quality that is cheaper than a big lens of high quality.

What does the type of light source have to do with lens quality?

In Kodaks presentation on laser DLP one important aspect was that the light source would allowed them to design a much smaller light engine and a smaller lens. I guess it has to do with that laser light is very "directional" and doesn´t need alot of collecting up.
I am sure someone can explain it alot better.

This is such a fluff thread. There are probably a multitude of reasons why we aren't seeing JVC come out with a UHD projector. My guess is it has a lot to with the "4K/UHD" economy. JVC has never been one to put out consumer grade projectors above $10000-$12000. To compete with Sony in overall picture/built quality, QC, lens quality, feature set, and brightness, they would need to bring a UHD product to market at a much higher cost over their current product line. My guess is that next year, when Sony has a ~$8000 4K product we'll see JVC come to the table with a similarly priced competitor product. The projector market is already niche enough and the $10000+ projector market is so niche that not even JVC could sell a projector in that price range and expect to move a lot of product. I don't think JVC sees this as a opportune moment to enter the UHD market. They may make a larger profit from these projectors at a higher price point but they won't be selling the same volume as their current lower cost 1080p products.

Other non-economical reasons for JVC could be low yield UHD chips. They may need more time to refine the manufacturing process to get higher yields of acceptable panels. There could be other technical difficulties they can run into such as video processing, especially if they want to do 8K e-shift, the processing power to do that has to be substantial and costly.

Maybe a competitor paid them a lot not to come out with it. That's it! Now it makes sense.

Excuse me, I have to go back to therapy with Coderguy and Mike.

Maybe; I thought the lens size depended more on the display chip size.

Ohlson is correct. With a laser light source you can have smaller optics and get the same kind of performance with a bulb based projector with larger optics. There is a thread that goes further into detail behind the science. I think it's in the $20000+ forum.

Lenses for laser light source can use a much higher effective f stop than a lamp lens. This due to the Etendue required of the lens is much much lower than a lamp source lens requires. The higher f stop means an increase in the depth of field eliminating the need to focus as precisely. We are talking savings of at least an order of magnitude with respect to lens costs.

Great! That should help a lot with offsetting the cost of new laser technology.

Apparently not enough though, or we'd have some laser pj's by now.

Hi Noah. The information I posted I got from a Coolscan post that I had trouble copying so I summarized it.

I think the biggest impediment at this point may be safety and regulatory related plus the speckle issue.
