Sharp's new AQUOS with red, green, blue, and YELLOW pixels

Sharp has a new set of LED lit LCD TV's with four different colored pixels. they say they can extend the color range of LCD TV's and even show colors that CRT's and Plasma's cannot. They say the colors are like bronze and shiny gold.

What's really interesting is that the human eye pre-processes the images it receives before sending the information to the brain. It processes colors by comparing red-green and blue-yellow so the eye should do better with this new technology.

has anyone seen one of these new TV's? Sony should be coming out with some soon for they were part of the R&D effort.

We'll have to agree to disagree about global warming until the next global cooling scare comes along

Waiting for a similar technology projector to come out. That would be awesome to magnify all its attributes (and of coure, any inherent weaknesses).

I haven't seen it but I do have a book on colour in interior decoration. In the appendixes it has a section entitled "How Colour Works" which describes 4 different colour models including the 4 colour RGBY model you refer to which was apparently formulated in 1878 by a German physiologist Ewald Hering. It actually has two 3 colour models, RGB and yellow/red/blue, the 4 colour model you mention, and another 4 colour model, the CMYK model which can be modified into a 6 colour model called Hexachrome by the addition of green and orange to the original 4 colours of cyan, magenta, yellow and black.

As to which model is better, I have no idea. My book indicates that the RGBY model has some advantages when it comes to colour choices for purposes like decoration since it yields a different set of secondary and complementary colours than does a 3 colour model but that doesn't necessarily mean it will be more accurate when used for video technology. A lot of printing apparently uses CMYK but Hexachrome is apparently superior to CMYK if you're prepared to accept the increase in complexity and cost.

A fourth pixel colour will make panel production more complex and probably more expensive as a result so even if the change does produce more accurate results there may well be arguments about the cost effectiveness of such an approach.
