  1. “it brings massive power efficiencies to displays compared to the e-ink technology used by Amazon’s Kindle”

    You mean *comparable* to. As written it sounds like the kindle has an inefficient transmissive display.

  2. This new technology sounds exciting. However, one point was slightly off — the current e-ink technology used in the Kindle and other e-readers also reflects light like this new technology. Thus, the Kindle’s display has the same power advantages as the new one discussed. The difference is rather that the newer technology may be brighter (reflect more ambient light) than the current generation and thus look more like paper.

    1. What do you mean can college kids afford this device?

      The kindle costs about $300, with books usually running about $10-$30.
      I spend about $800 to $1200 on required textbooks a year, and I buy them from amazon or other sellers not my college bookstore.

      The kindle will most likely be MORE economical, not to mention negating shipping times and costs as well as a heck of a lot easier to carry around (no more choosing which textbook to leave behind each day because of insufficient room in a bag).

      The question is can college students afford NOT to use this device?

  3. Pigment coloring sounds great though I wonder why they didn’t try simple RGB: Is it the resolution or the fine coloring which prevents this?

    1. Unlike conventional color displays, which create a range of colors by combining varying levels of red (R), green (G) and blue (B) light, a color display that reflects ambient light would most likely be based on the four primary colors used in the printing industry–cyan (C), magenta (M), yellow (Y) and black (K). Since these newer displays rely on an external source of light, they cannot create colors by adding anything to the light you see, instead, they subtract from it. While red, green and blue are the primary colors of additive color, in subractive color, they are secondary. It is their opposites that become the primary colors: cyan (-red), magenta (-green), yellow (-blue). Black (-white) is thrown in because creating black by combining cyan, magenta and yellow is not only inefficient, it also tends to produce a muddy-looking black instead of a pure black.

      A CMYK color display that uses ambient light is an exciting prospect for those of us who work in the graphic arts and printing industries. One of the most frustrating aspects of desktop publishing and digital pre-press has been the attempt to match colors produced on an RGB display with colors produced by a CMYK printer. A number of different color “matching” systems have been developed, but since the two methods of color have different overall palettes, you can really only match the overlapping colors. Other colors are “out of gamut” and have to be “mapped” to the closest available color, a compromise solution at best. A CMYK display would greatly reduce the disparity in colors. These displays would still have their inherent limitations and would not likely be able to display every color in the CMYK gamut (just as an RGB display cannot reproduce every color in the RBG gamut), but it would still be a huge improvement. Maybe in five to ten years I’ll be able to afford a high-quality CMYK display.

    2. Well the current method of flooding the display with ink of one colour wouldn’t work if you needed a CMYK pattern. I guess they’ll have to use an inkjet printer to distribute the inks to each cell.

      1. It didn’t sound like the display would be limited to pigment of one color, only the individual cells themselves. If the cells were arranged in a pattern of alternating cyan, magenta, yellow and black cells (just as the pixels in an RGB monitor are arranged in a pattern of alternating red, green and blue subpixels), a wide range of colors could be reproduced by dithering the four colors. It doesn’t sound like they are quite there yet, though.

      2. Yes, but if you watch the video of how they currently get the ink into the cells, you can see that they just flood the area with a single ink. So at the moment they have no ability to get different inks into each cell, thus limiting it to a single colour.

        Still, I’d be very happy with black and white if it improves upon e-ink’s speed and white level.
