Ive seen this commercial a few times but I still dont get it. I was told that with RGB, tint, and hue you could create over 16 million colors... youre telling me yellow isnt one of them? Why is this new pixel needed?
It's a gimmick. R and G make Y; there's no need for a yellow pixel. The human eye has rods and cones. The cones are color sensitive with 3 types: red, green, blue. That's why we use R, G, and B pixels to represent all of the colors. The human eyes and brain absolutely can not tell the difference between yellow light and the appropriate mix of red and green light. You need a spectrometer for that.

I agree in principal, but I believe the issue is that the red and green that the current LCDs produce is not a perfect red and green, so when you add them you get a poor yellow. This new tech is just taking some of the error out of producing yellows by producing it directly. Its not that different from laserjet technology where the good printers use 6 or more colored inks because the mixing of just 3 always creates imperfect results.

Red and Green do NOT make Yellow. Red Blue and Yellow are the THREE primary colors - just not that TV's and Monitors use (standard ones besides this one)
As for Sharp's TV - that looks pretty sweet, hope it turns out to be an awesome product!
Current flat panels don't handle color levels finely enough, and since the eye is very sensitive to yellow (it's flat in the middle of the rainbow, meaning the center of the spectrum our eye can discern), this lack of fine setting can be seen - adding a 'yellow' channel may just allow the screen to output more precise yellow levels, making the image look more contrasted. That wasn't the case with CRTs, due to the much more precise levels an electron beam could be set at.
Actually, right now the information carried by high definition streams allows the reproduction of colors that the eye can't really see well - so, with proper filters, it should be possible to have images that actually benefit from this process.
The second thing would be (it can actually combine with the first point) that it would allow a better interpolation on the subpixel level: while square pixels require three side-by-side very rectangular subchannels, adding a fourth one may actually allow for a square subpixel grid. Now, any of the three primary complimentary colors could have fit the bill: magenta or cyan. However, magenta is at the lower end of the preceptible color spectrum, and cyan at the higher end. Yellow is flush in the middle. So, back to point one.
It is a good idea. However, the reason why I'd never get one of those screens is because, well, subpixel font rendering would be screwed up by a non-RGB grid...
Don't let that fool you though, one reason for the gig is that, seeing the screen from the side allows us to see how thin the screen actually is...

Actually those are artistic primary colors. Red Green and Blue are the primary colors of light, and Cyan, Magenta, and Yellow are the primary colors of pigment (which is why those are the colors in your color printer cartridge).
