Go on Apple. Put that technology into a glossy screen and say it's good for us. We dare you.

I guess we'll have to wait until they develop CMYK digital camera

Seems to be a little too little too late, print being on the decline. As for a sensor, some of the cheaper cameras use a CMY Bayer pattern as it lets more light through, but the colorimetry isn't as good as RGB. In the old days, we had RGB+Luma tube cameras with four tubes. Obviously, K would be the inverse of luma.

Quick story on CMYK - some students in the design dept at a university had their graphic design prof fooled into thinking the K was for khaki.

But isn't the digital press industry growing pretty rapidly?

of course, technology companies apply for patents for nearly every idea they come up with ... I'm sure Apple (and others) have thousands of patents that never turn into anything.  Just because someone turned up a patent application describing an idea doesn't mean apple is putting any money into R&D for it.

The fact they filed a patent application may indicate they have no desire to try to make it themselves, typically with a new idea most companies will wait to file patents until pretty close to release so competitors don't' get to see what they are up to.

There are some CMY(K) displays for street signs in use already that are based on magnetically rotating balls with C+M+Y+K segments on their surface. Reflective lighting if I recall it correctly. There are E-paper display systems that use similar methods. I don't think Apple can make their patent that tight that other subtractive display technologies are no longer possible. Several other display methods allow subtractive color mixing. One may wonder whether reflective lighting isn't even better if printing has to be simulated. For today's N-color inkjet printers the CMY display may have a gamut that is too small to simulate their output. not to mention the neutral simulation of the K Dmax. For offset it could do a good job.

Looks like this is not Apple territory alone:

So did anyone notice that the link in the article goes to a patent titled:

METHOD AND SYSTEM FOR CONTROLLING VIDEO SELECTION AND PLAYBACK IN A PORTABLE MEDIA PLAYER

It says nothing about a display.

I think the correct link is here: http://appft.uspto.gov/netacgi/nph-Parser?...=DN/20100090930

Sorry, I noticed that too but didn't correct it. I did google the same page you gave the link for. If I check the basic technology described at the end of the page then I see many similarities with an original Philips development that now is continued by Liquavista, both based in Eindhoven, The Netherlands.

Either Liquavista was asleep on US patents (there is a Philips patent though) or we see another bad example of US patent practice.
