Organisms with tetrachromacy are called tetrachromats. [...] Humans and closely related primates normally have three types of cone cells and are therefore trichromats (animals with three different cones). However, at low light intensities the rod cells may contribute to color vision, giving a small region of tetrachromacy in the color space. In humans, two cone cell pigment genes are located on the sex X chromosome, the classical type 2 opsin genes OPN1MW and OPN1MW2. It has been suggested that as women have two different X chromosomes in their cells, some of them could be carrying some variant cone cell pigments, thereby possibly being born as full tetrachromats and having four different simultaneously functioning kinds of cone cells, each type with a specific pattern of responsiveness to different wave lengths of light in the range of the visible spectrum.[6] One study suggested that 2?3% of the world's women might have the kind of fourth cone that lies between the standard red and green cones, giving, theoretically, a significant increase in color differentiation. Another study suggests that as many as 50% of women and 8% of men may have four photopigments. Further studies will need to be conducted to verify tetrachromacy in humans. Two possible tetrachromats have been identified: "Mrs. M," an English social worker, was located in a study conducted in 1993, and an unidentified female physician near Newcastle, England, was discovered in a study reported in 2006. Neither case has been fully verified. So there you go, if you happen to be a Tetrachromat, by all means feel totally justified in forking out extra cash for your super fancy TV designed for your mutant eyes.

Cool beans - http://www.engadget.com/2010/03/22/george-takei-cant-show-you-sharps-fourth-pixel-can-still-blow/ In related news Apple files a patent for a CMY display using subtractive CMY filters instead of additive RGB light.

Cool beans - http://www.engadget.com/2010/03/22/george-takei-cant-show-you-sharps-fourth-pixel-can-still-blow/ Not cool, complete BS. I can see yellow on my TV just fine. If you recall from grade school science class, Red + Green = Yellow. Yellow is not a primary color. May has well have magenta and cyan LEDs while you're at it. And also as a reminder, the cones in your eyes only detect Red Green and Blue. http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html Now if you are using a subtractive method of pigmentation, such as with paint, then you would use your three secondary colors, cyan, magenta, and yellow. That works, because the pigments absorb colors and only reflect back the RGB.elements that make up the color. You take some yellow paint... it absorbs blue light and reflects back red and green. Mix that with Cyan, which absorbs the red light, and you are left with only green being reflected back.

Since the red and green are cancelers, the yellow that is already present is seen. Now I could see the argument that adding a yellow would make the effect more vibrant, but simply intensifying the white light would do the same thing... I have no particular investment either way Welcome to the Internet, everything is ridiculous here. |

If you added blue, in theory you would then have black, but again because the perfect matching of pigments, you get a dark brown. That's why it's CMYK. When working with light however, it's an additive process. Yes you can cancel things out, but that's only where the wave forms cancel each other out. Since red light is at a different wavelength as green light, they can never completely cancel one another out. I suspect that if you setup an experiment correctly and used pure laser source for each, you could see some banding. Now strictly speaking, light is just not strictly the three wavelengths of red, green, and blue combined, but rather a multitude of wavelengths. So the correct ratios of ~680nm red light, plus green light ~520nm, isn't exactly same as ~580nm yellow light. Your brain just perceives it as such, since the response of the three types of color sensing cones in your eyes is similar. I still don't see how "seeing" yellow by triggering your red and green cones equally by a single yellow light source at 580nm is any better or worse than seeing yellow by triggering your red and green cones equally by a red and green light source at 520nm and 680nm. There is a theory out there that your eyes actually work by differentiating between white and black, red and green, and blue and yellow. But that's more in the brain, and not at the physical detector level, since you still have rods, and three types of cones, which are more sensitive to red, green, and blue light. They don't tell your brain, hey I see X amount of light at 580nm... they say I see X amount of light on my red cones, and X amount of light on my green cones. It only makes sense that since the data the brain is getting is RGB (plus the data from the rods, which is strictly light vs dark) there really isn't a benefit to taking a digital RGB signal, converting it to a RGBY light, only to have it converted back to RGB again.

If you have something that can now show yellow, instead of using two other LEDs for that those two colors can now still show the green and red while you still also have yellow. Now..

If you have something that can now show yellow, instead of using two other LEDs for that those two colors can now still show the green and red while you still also have yellow. You can do that now. Not that it matters, since we're talking pixels here. A pixel is only going to be a single color, despite there being three or four LEDs used to make that color. Now.. I will saw that brings questions into how will it work with current color decoding and signals. But.. it's a cool advancement. It accomplishes nothing, since you have to dim the red and green LEDs when displaying yellow... I mean you could turn them on to have a brighter yellow, but oh wait, you can do that now by turning on the blue LED. That and you would still have to do that, since the only way you get closer to white is by adding blue. And of course the data is currently transmitted in RGB color values, so anything involving the superficial yellow LED has to be recalculated anyway. The only thing I could see it possibly doing is saving a minimal amount of power when you displayed something yellow, since instead of having to light two LEDs, you only have to light one. This is assuming that the single yellow LED was as bright as the red plus green LEDs combined. Typically yellow LEDs when driven the same as you would a green or red LED are not as bright, so I believe any gain would be negligible. A good way to see an example of this is to take a RGB LED and slowly reduce the amount of voltage sent to it. You'll see blue cut out first, followed by green and then red. http://en.wikipedia.org/wiki/Light-emitting_diode#Colors_and_materials Don't hate. It's a stupid idea. I'll hate as much as I want.
