The future of RGB: RGBY?

[bluestarultor]

I saw a page ad for this and thought it was a joke, but no, they're apparently serious. The idea is that somehow by adding a yellow band to the RGB model, it makes it easier to produce yellow colors. I'm ready to call bullshit on this, since basic color addition says that red + green = yellow light. Aside from that, there's nothing in TV signals that accounts for an extra primary color, so either they expect it to somehow catch on or it does some arbitrary math in the unit to convert red and green signals to a yellow signal, which is no help at all.

Maybe it has something to do with the human eye placing red-green and blue-yellow in pairs and it just not having to work as hard with the pixel blur or something, but given the human eye only has cones for red, green, and blue light, I'm calling shenanigans.

Thoughts?

Though the addition of a yellow bar is pointless. I can't really see this causing any real harm to TV contrast.

It's all a scheme to make you buy it as obviously superior to 3 color versions.

I don't know. Yellow does sound simpler than red+green.

Theoretically at least lighting a red and green pixel takes more energy then just lighting a yellow one. Don't know how accurate that is and the overall savings in energy probably isn't worth it. It could probably also simplify the creation of other colors as well.
