Sharp Reveals 3D LCD with 4 Primary Colors
Sharp is adding 3D LCDs to its Aquos line.
Sharp is claiming the title of "world's first" with the development of its four-primary-color 3D LCD for its Aquos line of HDTVs. The "Quattron" technology already made a splash last month with the introduction of the Aquos LED LCD TVs, reaching the public eye in a rather comical way thanks to George Takei's TV spots. As reported last month, Quattron brings a fourth color into the previously-standard red-green-blue setup: yellow.
In addition to the Quattron tech, Sharp believes it has solved the low brightness and ghosting (crosstalk) issue seen with conventional displays by incorporating four other Sharp-branded technologies: UV2A, its own core tech for LCD TVs, FRED, and side-mount scanning LED backlighting. According to the company, the 3D LCD is 1.8 times brighter, and the colors are more vivid thanks to the red-green-blue-yellow setup (and a wider gamut). The side-mount scanning will help reduce the amount of ghosting, and boost overall picture quality.
Sharp executive vice president Masafumi Matsumoto said that the company will officially unveil the 3D Aquos models in May, and will launch them in Japan before the summer shopping season (possibly June)--no real ship date has been set. He also added that the company will reveal technical details about the new 3D Aquos next month.
As with other 3D HDTVs launched this year, Sharp's 3D offering will require active shutter glasses to get the full 3D effect.

i'm sure it will cost about 3x what my 60" mitsu dlp did.
now we have to wait for A. several more generations or B for 3D to blow over

please be B.
yes please be b for glasses wearing tech.
it would be interesting to see how much a difference that 4th color (yellow) makes. I wonder if its a marketing scam and they just add a red and a green and call it yellow.
I'll be buying this as soon as one of you guys gives me the money for it.
Still waiting for them to concentrate on true holographic projection technology so we can do away with the need for physical screens.
- I can just see one of the first uses for Holographic Technolgy once it becomes practical.
Replace stop signs with holographic projectors which project a large (physical seeming) brick wall across the lane the car/s in with a large stop sign on it and the wall would only disappear once the car comes to a complete stop.
Now that would be a way to stop people from running stop signs.
I completely dont understand why 4 colors are better then 3.We only see 3 colors so why 4?
this 4 colour system is supposed to improve yellows like golden and bright yellows, due to the filters in LCD technology their is a massive dip in the yellow area of the colour spectrum
i would imagine that screens such as oleds wouldn't have this problem with the colours being lit directly at a per pixel level without any transmissive layers in between

No, we see 32 million colours (around), not three. Adding a seperate yellow channel will ensure yellows get displayed properly.

dude if you only see 3 colors you really need to get your eyes checked

learn more about how colours in a display are produced before commenting you only make yourself look extremely stupid
omagash! my dog it's red! why didn't you told me b4!?!
Mom? have you seen my t-shirt?
M: which one? red, green, or blue?
Sammy.. I don't like this kinda girls for you son..
What kind dad?! what!? green!?
People we only see 3 colors phisiology of the eye http://en.wikipedia.org/wiki/Primary_color. All other colors are mixtures of these 3.So actualy you dont see 32Milion colors or something. You see 3 colors. But your brain interpretates different intensyti of these 3 like some other color for example yellow. Simply for most people its hard to understant that they actualy see 3 colors but brain tells them that its actually more then 3.
I might be wrong on this not sure but wouldn't the picture have to be transmitted differently? What i am saying is wouldn't this require a special Connection or some other item to take advantage of the 4th color added or will it be processed in TV..... I would also think items such as a RGB cable wouldn't work or if they did they would give color with out the 4th yellow color.... guess i am just little skeptical on this seems gimmicky to me
Question: Why won't they just turn every other (sub)pixel by 90deg? LCD shine polarized light so all they need to do is rotate half of the pixels by 90 deg and you could watch it with 10$ passive glasses + there would be no flickering and headaches from shutter glasses + you'd get higher resolution in 2D
^^
The LCD controller does that job just as much as it converts rgb values into lights on/off and intensity.
Does any one know how this would compare (in terms of color quality etc) to a high end IPS based LCD?

There are only 3 color receptive cone types in the human eye... red, green and blue. http://hyperphysics.phy-astr.gsu.e [...] on.html#c1
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.
i'm sure it will cost about 3x what my 60" mitsu dlp did.
And it will look 30x better.
The primary colors are red, yellow, and blue. green is a mixture of blue and yellow.
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.
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?
