I have been saying this for years. We have had seven color printing now for a long time

So now the "Dream-Machine" will be 1920x1080 and in a 7 chip configuration.


WE'LL SETTLE FOR NO LESS :)


That really beats CRT !!

That would be hard, but it would be good for single chippers,

Wow imagine the seperation artifacts on that beast

How did you fellas read this article. It is in Swedish. Do I have to do something to translate it to English ? Sure looks interesting.

The article is in German and can be traslated using babelfish.

I counted six primary colors.

..................

Your right but I thought It wouldn't hurt to add one more. More has to be better,..? Call it magensepheuse-x :)

Not if its a seven tube CRT !!!!!!


(What, a 700 lb behemoth won't fit through the front door? Convergence takes 7 days? Cost 7megadollars? It's perfect for 7.1 surround.)

This is gonna throw a wrinkle into GLV development.


Gold lasers?


Not to mention, we'll need quad link DVI to handle the data stream.


I think I'll give up HT and go back to my googlephonic turntable with a moonrock needle.

It would be easy, by contrast, to build a 6-chip D-ILA or SXRD.

Philips treibt's multicolored: the most colored television of the world. The correct representation of colors is with electronic pictures a delicate thing. Until today no screen or projector can really show all tones of the visible spectrum; than this spectrum the range of the colors occurring in nature is somewhat smaller, but also covers things such as gold or magenta. The color extent of the television represents a still substantially smaller cutout. It is co-ordinated with that, what one can show with the phosphorus mixtures of a picture tube, is thus clearly under the color extent of 35-mm-Film. Nevertheless many manufacturers of projectors or LCD monitors would be glad to be able to reach at least the tube spectrum. Philips states now to be able to bring with conventional projection lamps colors never seen on the screen or the canvas. Because the dilemma so far lies in the filtering, which is always a compromise between light achievement and chroma: In order to meet for example red accurately, one must filter all blue and yellow portions; if one does that, only a very narrow-band portion remains - the red filter lets more, is pure red through already no longer possible, the colour tended usually toward orange.



Genoa Logo: magenta, blue, cyanogen, green, red and yellow unites.

Philips wants to solve this problem by the fact that one filters more than three colors. Additionally to red, green and blue Philips's will introduce also filters for cyanogen and Magenta. Thus the individual tones can become sort-purer, and also the possibilities for mixing tones become much larger. The technology in addition is to come from the Israeli company Genoa Color Technologies, a small company into Herzlia (or Herzelia), which wants to demonstrate their procedure for the first time in May to a conference publicly (with the Society OF information display ). Technicians, who saw it already times, turn out in swarms: "magenta is magenta and even gold can be represented", so Philips manager Joep Thomassen. To be used the Genoa technology is for the first time in LCoS televisions of the dutchmen; whether one then with five instead of three rotating prisms (see message of 8. 2. perhaps 2001) to work want to produce or with a prism two colors can, are still secret. A problem applies to certainly consider it: All electronic pictures are with the displays from today co-ordinated (or with from yesterday, the tube), a transmission one to one on the extended color area to fehlfarben would lead. Here it applies to develop a color space conversion, which deals carefully with the new possibilities, but her also does not give away. A procedure for it had itself patented laser TV developer Christian hard Deter (ex VEB Zeiss Jena, ex cutter); also lasers or light emitting diodes can represent substantially more colors than tubes. One will have to think in foreseeable time to extend the color area of electronic pictures clearly.

Example: Did you think already times about it, why one calls the German flag black-red-golden, it however always contains yellow instead of gold? Because gold in medialer representation, all the same whether print or TV is, in each case a dirty yellow (26. 4. 2003)



Uneasy triangle: Within this area the colors of the visible spectrum move. In the center white is to be found, the mixture from all spectral portions. The curved external line consists of the pure colors, which have only one wavelength. The sRGB range corresponds in for instance the color area prescribed for PAL. NTSC is shifted against it more toward green.

They will start with five primaries and extend to six when the system is developed.

To start of they will use red, green, blue, cyangen and yellow. The siixth primary will be purple(magenta is that the same thing?).


This review describes what it looks like.

Perhaps unfair to compare with an old dlp. From what I understood they used a modified dlp engine, but with how many dmds?

It seems to me, and maybe I'm just thinking about it wrong, that using the secondary colors as the other three doesn't necessarily get you a wider color gamut unless they are more saturated versions of the secondaries than you get with mixing any two of the primaries. So you could have a 6 color system which looks no different than the existing triangular gamut of RGB. If the secondaries are more satuarated, then they would 'poke out' on each leg of the primary triangle, turning it into a kind of hexagon shaped gamut I guess. That still would leave out a lot of the visible spectrum, but it's obviously a bigger gamut than RGB, according to how much more saturated the secondaries are.


To help picturing it, picture the RGB gamut as a triangle. The secondary gamut would be nother tringle overlaid on the first, creating a kind of 'star of david' shape. If you then connect all of the outer points you'll have a hexagon shape, which has six smaller outer triangles. This what it would basically look like as long as the secondaries are more saturated than then mixed versions of those colors in the RGB triangle.

If you read the article on the impression of the color gamut and the joint press release with Philips as well as some other press release you wil find that they mention a polygon shaped area for the color gamut.


I am sure they use saturated colors for new primaries since the whole point is to increase the color gamut.


It does sound interesting. It is supposed to be demonstrated at SID 2003.

The problems with color gamut won't be much different (if at all!) from what printing houses and inkjet manufacturers have to deal with. 7 color printers are becoming more popular nowadays (the 7th color is usually a black though...equivalent to a white segment on a projector).


It's gonna be hell to calibrate this machine! And, all the HDTV programs are encoded with the HDTV color standards...you don't want your yellows to turn into gold when it is supposed to be yellow!


On the other hand, quite a few cameras can capture a wider color gamut than CRT devices can display. Knowing the color space that the camera outputs is going to be critical if we want to take advantage of the wider gamut this new technology offers...


So, when will we see the "SuperColorBit" DVDs that are especially encoded for these new machines? :) I have a feeling we're gonna run out of bits real quick...

A hexagon color gamut. That really is some out of the box thinking.


It's really going to do a heck of a job on ColorFacts, though. There is no way to plot anything other than an RGB triangle. Luckily, the spectroradiometer itself will be able to plot the hexagon once it is supported in the software.


Tristimulus colorimeters, though, are going to have a really tough time trying to analyze one of these.
