It might be pretty obvious from a very clearly defined side-by-side comparison, but when the entire display is in reduced color mode it might not be nearly so noticeable.

I really like the idea of having the ability to specify which display mode you get. Though I have to say it - the iPhone 4GS^3 will only have the low-color display because Apple will decide it's better that way. On the flip side, the ZunePhone 2 will have both, but it will only switch by screaming the word DEVELOPERS at the phone several times.]]>Jul 8th 2009 11:14AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/

Wikipedia:
Color blindness, or Colour blindness, a color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish.

Do you see "grey" (or "gray", whichever you prefer) in there?]]>Jul 8th 2009 9:52AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/
People complain about the color spectrum of some screens, and I am like....."Looks good to me" :)

And BTW, while I do miss the old B&W Atari days, we can see color. Games like Super Puzzle Fighter (which I love and hate) can be difficult, because the yellow and green gems look very similar (at least for me). Bejeweled is another, because two of the gems have a similar color AND shape..... (the circle/octogon yellow/green ones) I wish they would change the shape to be more distinct, but I just have bad eyes.]]>Jul 8th 2009 10:02AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/
If the colorblind manages not to freeze or starve that first night, there is a chance, however slight, that he/she might find a clan of roaming colorblind homeless to band with. More likely they will eventually just be eaten by a lion. If you think seeing a lion hiding in the grass is hard enough using all the light in the rainbow, then you've never been colorblind.

Sad really. I once set up a rally for the colorblind in my town. I designed these beautiful red and green posters. Just stunning. Yet all that work and not a single colorblind person came. Naturally I held a grudge.]]>Jul 8th 2009 12:37PMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/Jul 8th 2009 12:47PMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/
Our eyes can only perceive so much, and our current media formats only have a limited range of color anyways. It would be one thing if you were watching uncompressed 1080p video with 4:4:4 color, but with bluray, let alone cable or streaming video, there would be no difference at all, other than the number of colors listed on the box would be lower.]]>Jul 8th 2009 9:39AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/

Seriously, maybe you have a hard time being able to articulate what is lacking with these reduced-color displays, but I think many people would sense that there was SOMETHING missing, and report having a less enjoyable experience. I can't really explain to my friends why my classical music is encoded losslessly on my computer, but if someone converted the files to 128kbps MP3, I would notice that something was lacking... maybe not on their shitty computer speakers, but on my canalphones or my Paradigms, you bet your sweet ass.]]>Jul 8th 2009 9:58AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/

This isn't about Blu-ray, it isn't about video. It isn't about any image which is already rendered and thus has a fixed color set. It's about if you are creating images in a UI, you can select colors that use less power. First you can do it be selecting colors which don't turn on at least one of the (RGB) sub-pixels. So, for example, instead of using brown, you use orange. Second you can do it by using red and green more than blue (blue takes the most electricity).

It won't look like the original image, so you can't use it for pictures for example, but for things like google maps that display information with colors you can design an image using this restricted color set that conveys the same data that another, more power-hungry image would.

The best way to save power is to use darker colors as much as possible, black doesn't turn on any sub-pixels at all. And companies already know all this stuff, this is why the UI background on the Sony music player, the Zune HD and such all use black as the backdrop.]]>Jul 8th 2009 11:38AMhttp://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/http://www.engadget.com/2009/07/08/limited-color-oleds-could-operate-with-40-percent-less-power-lo/
