Sharp Reveals 3D LCD with 4 Primary Colors

[loomis86]

The primary colors are red, yellow, and blue. green is a mixture of blue and yellow.

well...

#1. you can achieve more colors in the gamut by using RGGB (two hues of green) over yellow.

#2. no existing technology uses RGBY or RGGB so what is the point unless it can upconvert?

#3. active shutter glasses require batteries

The red, yellow, blue are the primary color for PIGMENTS. (Such as paints) Pigments work in a different way than the actual lights from displays. For example, mixing blue pigment(reflects blue, absorbs orange = red + yellow) and yellow pigment(reflects yellow, absorbs violet blue = red + blue) yield green not absolutely because blue + yellow = green, but because blue and yellow interferes with absorption of each other. Therefore in the above example, red, yellow and blue all gets absorbed leaving green. However this is not how it works for lights for displays since there is no absorption of any kind. The term 4th primary color is wrong, since there can only be 3 primary colors whether in additive (RGB displays) or subtractive color (pigments) mixing.

And it will look 30x better.

Red, green, and blue are the primary emissive colors (for things emitting light.)
Magenta, cyan, and yellow are the primary reflective colors (for paints and inks.)

Color perception is complex. The retina and primary visual cortex actually develops basically three channels, which correspond to a Red-Green axis, a Blue-Yellow axis, and a brightness axis. That is why you can't perceive Red or Green simultaneously (there is no such thing as "reddish-green"), or Blue or Yellow simultaneously (there is no such thing as "bluish-yellow).

Well I hope gold looks good on those sets, since its worth its weight in gold.

 

[ooo]

They are actually introducing a four pixel colour,i hope they finally can reach all the NTSC spectrum...

what a cool discussion, whos right in here? mr tuel sounds closest to what i understand, but i dont know scrap about oled,
doubt ill be buying one, at least soon.

So what exactly is a "3D TV", should one read this as "a TV with 200+hz and a strobe signal for special glasses"?

Why can't we have this as an addon to existing TVs?
