Sharp develops worlds first four-primary-color 3D LCD : DigInfo

[urantivirus]

I can adjust my normal monitor/video card to display yellow exactly the same. I can tell the difference in yellow on the video and my pixels only contain 3 colours. This looks like marketing scheme.

With additive mixing, you can make CMY with RGB (R+G->Y) (G+B->C) (B+R->M). With subtractive mixing, you can make RGB with CMY (C+M->B) (M+Y->R) (Y+C->G). CMYK is the used for printer ink, so yes they can work for pigments, and they can be considered to be primary pigments. RYB can work for pigments as well but you will need white to produce better reproduction of cyan and magenta.

red+green=yellow, green+blue=cyan. so y add yellow instead of cyan? because most consumers think red yellow and blue are the primary colours and so they quickly accept that adding yellow to the standard rgb system is important. 

[kmarinas86]

@7heReaper

The eye is more sensitive to yellow. For the same energy consumption, yellow stands out more. Yet, red and green to make yellow is not as energy efficient as using yellow directly. Many monitors already have a cyan tint to it, so cyan isn't as important than adding yellow, though it is obvious that if it were included, the monitor color range would be increased even more. I have seen the Aquos in person, and yellows on other monitors look like butterscotch by comparison.

[7heReaper]

@kmarinas86 you were just dazzled by they fancy video they had, im looking at my lcd rate now and the yellow isnt "butterscotch"

[kmarinas86]

@7heReaper

The capability of LCD's being adjusted is quite obvious. I can do that with a graphics card driver. The adjustments in most screens are often off. Color reproduction could be much better, though I'm not saying that Quattro is the best. I can generate vivid colors with my own LCD screen - too vivid even. Color reproduction involves more than just the extremes of colors displayed. It also has to do with small differences in colors, in addition to efficiency, which I already mentioned.

[7heReaper]

@kmarinas86 a yellow pixel at 100% = a red pixel and a green pixel at 50% now how is 1 pixel at 100& more efficient then 2 at 50? this is simple math

[kmarinas86]

@7heReaper

The eye doesn't work like that. Vision is logarithmic. Log(2) + Log(2) is not equal to Log(4). I suggest that you expand your knowledge.

[kakureru]

its like turning up the color saturation.

Until yellow becomes as active part in the capture AND encoding as are red green and blue, I dont give a flip about display voodoo.

[kmarinas86]

@kakureru

You are totally correct.

[orthant]

Greatest cheating in the history of electronics.

[taofledermaus]

@orthant It is a scam. I enlarged the pixels using 200x magnification and there are only 3 colors on my Sharp Quatron! There ARE NO YELLOW pixels.

[kmarinas86]

@taofledermaus

You have a fake one, or for some stupid reason the yellow doesn't work your Quatron and you forgot to consider the unlit area as the unused yellow pixels.

[johneymute]

what many peoples dit,nt know is, that sharp also had introduced the world first large color lcd screen in 1988 and they also had made the first color lcd tv back in 1991.

[mitch19636]

#1. There is no content available that supports Quatron period.

#2. No one can distinguish between a standard LCD TV or a Quatron TV

#3 In testing yellows had a brownish tinit. (Yuck)

#4. How does Quatron help Black levels?

[huddyyeo]

FRED TECHNOLOGY?

[kmarinas86]

Human vision is not exactly triangular, therefore it is bit like having 3.5 primary colors, 3 primary and 1 color between primary and intermediate, or even 2 primary and 2 between primary and intermediate.

Primary colors for light = RGB

Primary colors for pigment = RYB

Question: Why is human vision like that?

3D TV 20 years from now could use rotatable metallic pigment spheres and lasers to bounce off of them so we might actually need "four" colors. Think about it people!

[enochs3513]

@kmarinas86 to much stufff!!!!

[cinevidproductions]

@kmarinas86 Aren't primaries for pigment are Cyan, Magenta, Yellow and Black? Is it human vision or is it the nature of light as seen by the way light splits through lenses and prisms?

[kmarinas86]

@cinevidproductions

Answer to First Question) RGB is the model most often used in art classes, but CYMK is the color model (combination of 3 hues + black) that best maps typical human vision. So if you wanted better accuracy to human vision, you need a 4th component hue, but the 4th is not regarded as "primary".

Answer to Second Question) The primaries derive their relationship to due the biological response to light through the cones in the retina. In most people, 3 types of cones exist.

[7heReaper]

@kmarinas86 the primary colours of pigment are yellow magenta and cyan jackass

[kmarinas86]

@t.r.

I was referring to what is typically used in art classes. Did you notice the disclaimer I gave? In any case, even with C, M, and Y pigments, you will need black to really reproduce a wide color range. Also, when not dot-matrix printing, but rather mixing paint, turning bright pigments into "white" is much more difficult than mixing dark pigments into "black". NO set of three colors can accurately produce all colors through subtractive mixing without dot printing - W &/OR B must be added.

[kmarinas86]

@kmarinas86

* dot printing *.... or alternatively, 1) laying a very thin layer of paint, 2) using a clear layer, 3) etc.

[Nullstr1ng]

this makes iRobot more fake

[poisonsting8404]

the only thing thats kinda annoying about this is.....Yellow isnt a primary color lol

[vrshowdown]

@poisonsting8404 correct ! when it comes to light , yellow is not a primary color .. but yellow is a primary color when it comes to paint and opaque objects .

[Minamiblues]

Oooo, I like the colours... shutter glasses is good too, less trying to find the sweet spot of the tv, and easier to develop content.

[adamitshelanu]

njce

[SandBarAndYou]

There are only three primary colors. Yellow is a secondary color. Duh.

[MrTriTanium]

@SandBarAndYou Wrong!! Yellow is a primary color in a 4 color tv, along with red, green, and blue.

[SandBarAndYou]

@MrTriTanium

No, you are wrong. There is no color space that requires four colors as "primary." If red, green and blue are all there serving as primary, then the yellow is a "fiftth wheel" so to speak and is therefore not primary. Yellow serves as primary when dealing with pigments, not light. If blue, green, yellow and red were vectors on a color space, they would NOT be "linearly independent" vectors.

[MrTriTanium]

@SandBarAndYou I was talking in the context of the Sharp tv, not actual light.

[SandBarAndYou]

@MrTriTanium

Well the TV produces light (as opposed to pigment). Calling that fourth color primary while the other three still retain that title is a misnomer. To do that is to ignore why they were called "primary" in the first place. I'm sure they've done it only to avoid confusion. "Three-primary-color-and-one-s­econdary-color" TV just doesn't roll off the tongue.

[1ownjoo2]

Who the hell is going to put on big 3d glass's everytime you watch TV.... When i want to relax and be lazy i just want to watch TV... not be botherd with putting on huge 3d glass's just to see some extra color...

Not to mention i get minor headachs's after watching 3D movies.. Sure thsi is cool but its not for everyone..

[Troothforc]

"which displays yeller" 0:38 nice to know they were thinking of the Disney classics when they made this

[destin325]

i hope sharp teams up with oakely to create some decent glasses to wear and not those ugly back-to-the-future blocks they were wearing.

[GreenPliskin]

can't wait to hear about the eye problems this is bound to create.

[yahoopl3]

what's with this lcd shit? i thought led was the newest thing out there..why are they going backwards

[danielguy1234567]

wow thats amazing I want it.

[mranenome]

My eyes are messed up enough already.

[spacecoke]

yay new tv's already! now maybe big 2d flatscreens will go down in price so a can afford one lol

[magnumcyclonex]

Just imagine the movies, games and shows we all watch and play. They will be much more stunning!

[dragonball070]

lol "fred" technology!

[dave577hele]

i already have a 80 inch quattron tv

why ?

because im rich.

[joelito101]

I want one!!! My porn will look that much nicer!!!

[EliesLoveViki]

what will be the price of this 3D LCD tv?

[wtf666000]

o wait i need to test ru it please send me a free one lol haha

[Zonde32]

is it CMYK?

[Casper123666]

@Zonde32

No, it's RGBY, it's a new technology by sharp. It has been said that it provides better contrast and the images will seem more colorful.

[Zonde32]

CMYK creates the best contrast of between the two we mentioned. i believei ts

Cyan, magenta, yellow, Deepblack(K)

[Casper123666]

@Zonde32

I know what CMYK is.

But you asked if these screens are CMYK. They aren't, they are RGBY, a new technology by sharp, as I already mentioned. You can google it if you want, but this whole video is practically about this new RGBY technology.

[Isanion]

are sharp from the future or something?

[bie5436]

i think we should be implanted with 3D lens in our eyes. LOL

[mixed123456]

as always till is not ready for the masses the prices is too high. so i don't think its a need to buy one of this. but ofc. if you have the money why not ?

[conailz]

is 3D television a need or a niche?

[pubtor]

3d without glasses please

[yeomond]

if the 3ds has this, -win-

[OmgThisGuy]

sweet, 4 primary color tvs, been waiting for this technology forever.

and what's with the video title?

[GTARIST4EVA]

woa...
