I saw on the video that Mary Lou Jepsen actually reads this thread!
I wondered if ever replacement screens will become available,it would nearly be impossible to keep track of all sizes and differences in screen controllers. How would they solve the problem of the DIY who takes out his laptop/netbook screen and replaces it with the PixelQI? Not only does the screen need to have a small change in drivers (to support B&W), but the LCD connector pins need to be the same as the original, meaning,if my LCD screen comes with a connector like a zif connector, it's easy replacable. But I'm sure many models out there will not have the standard connector pinns. (and, of course, the screen need to be the right size and resolution). If they do plan on making netbook replacement screens, I hope they will send a sample to JKKmobile to do. He does good reviews, and with a little video from a trusted source, I'm sure a lot of people will feel more secure in doing this themselves (that is,if not too much soldering and fine electronic modifications are necessary). BTW, did pixel Qi use a technique to improve light reflection on the white background by using a technique similar to the one found in reflectors? (Eg: transparent plastic with triangles on the back)? I'm sure I saw that the screen focuses the light into the area where the head of the user would be; cause when the camera went lower, the screen turned darker.

Industry is all about money for the big heads, and I doubt if they have found a way to improve, that they won't charge for it... They will..most likely... It's only competition that gets them to lower price... Or perhaps I've just seen too many companies rip off people and fill their pockets on people's innocence/unawareness/or ignorance (of something they had no clue of)... sorry about the last sentence, I could not find the right English word for it.. Also, don't expect these kind of numbers from powersaving! Like they say there's a 2,5 to 3 watts powersaving without backlight; that translates into about 15% powersaving. On a netbook that is rated 3,5 hours you gain about 30 minutes of battery. On a laptop chances are you save less,partly due to the chipset that consumes considerably more power than a netbook (about 4 times more;while the saving of energy on a laptop screen might be only 2x that of a netbook) Last edited by ProDigit; 06-08-2009 at 02:17 AM. |

Just because I'm sure I'm missing something, a quick general question. When the device is in non-backlight mode it does not have color correct? I'm sort of lost on what their 3 screen options are, is it backlight on (color) backlight off (B&W) and dim backlight (color)?
I'm glad that they are thinking of selling the screens separate for existing laptops, that might be the stronger move for me to just update the netbook I have now (might have to figure out some mod for that backlight off switch), it shows that they are serious about getting this product out to as many people as possible early. I'd like to update my netbook now and wait until next year when the optimized Pixel Qi netbooks come out to get a new one. |

(1) Backlight color (basically regular LCD) (2) Transflective color (dim backlight LCD) (3) Backlight off B&W (aka epaper) Did anyone notice from this video that the Kindle (eInk) has much better contrast than the Pixel Qi's epaper mode, or was it just me? |

Awesome, just awesome!
I was pretty sceptical earlier due to the lack of images/video but now that they're cranking out more and more details and detailed video of the thing I'm totally thrilled! I really want one of these. I'm semi-prepared to instantly donate all of my printed books to some charity/second hand outlet just to show my devotion to this thing

I am still quite skeptical about this display technologies hitting the market at the price they are targeting, because adding a metal layer on the TFT array has never been proven to obtain a high yield rate. Even when Sharp or TMD were making a transflective display, the yield rate is quite low, so that means if the yield rate is low, then the price of the display will be expensive.
I hope I am wrong. |

But what I presumeis,that the LCD is color all the way. Only, you can not see the colors, if there's no back light. It hasto do with how the crystals of the LCD interact with the polarization filter. RGB becomes 3x a different type of grey. The sun needs to travel through the first polarization filter, the LCD, the second polarization filter, bounces on the back, back through the back pol filter, the LCD crystal, the front pol. filter, before it reaches the human eye. So everytime it goes through a filter, some properties of the light are changed. And it happens to be that the properties of light passing twice through an LCD screen are different;more changed, than the properties of light that goes straight from the back, and passes only once through the LCD. It's best comparable to looking to the sun through a red filter. You will still see yellow and perhaps measuring equipment could measure very faints of green and blue passing through. But most green and blue appear as dark brown or black through the red filter. In a same manner light that has passed twice through the polarization filters is only able to display light or dark; not really color. Perhaps this has to do with the crystals in the LCD screen, or perhaps with the properties of the polarization filter, I don't know... In any case, I'm sure the results are very comparable to seeing webpages and pictures on a laptop with a reflective screen, in bright sunlight. The screen will look green,but appart from that, you may be able to distinguish colors very faintly. So I believe just like a laptop, that the screen does not change modes, it stays color, but it is the environment light that quenches the colors, while keeping the contrast. |

My estimation is that a netbook equipped with this screen will not cost more than $50, because the build material is very similar to LCD;in fact is the same but little optimized. From a marketing perspective they are also not able to ask too much money for the technology, because the little battery life you gain over the many colors you lose will be a 'no' for many... It will be a technology probably mainly aimed at netbooks,and low price laptops. So the price can't get too high. Also I thought they mentioned trying to get the technology to Africa first. Another clue that it will definitely not cost that much more, compared to a regular screen. I heard they where trying to fuse the OLPC screen with their current technology or LCD screen (by using diagonal rows of dots instead of horizontal rows of long pixels like used on a TV). That would yield yet another increase in resolution! |

Meaning, even if the background is as white as white can get, and as reflective as possible (to reflect the sunlight near to 100%),the light still needs to travel through a bunch of layers (glass, polarization filters, and LCD crystals) TWICE (meaning once to the back layer, then through these layers again) before it becomes visible to the user. The light will lose some of it's intensity,and there's not much that can be done about that; but just for reference: Pixel Qi's contrast is better than the Sony PRS-700, due to the 700's touchscreen. So if you're happy with the PRS 700, you certainly will with Pixel Qi's screen. Last edited by ProDigit; 06-09-2009 at 11:26 PM. |

For the B&W, I noticed in one of the videos that when it was in the B&W mode they mentioned that there is still some color hinting that goes on and you could see some yellows and oranges so you are probably right about your comment on the way the screen works. We'll have to wait until the screens are out to see it in person but I think that this could be a big move for netbooks, maybe the smartbooks as well, as they are typically made to just quickly surf the net and email. Having something that feels better on your eyes would be a huge plus for a lot of people if the products are marketed correctly. I don't foresee these screens in the latest MacBook or high end computer because as you noted the color quality might not good enough for people doing video editing and photography but for the average user it'll be a plus. Its good that they are getting a bunch of videos out there and trying to spread the word about their product, it gives me hope that this might really take off which I want to see it do because it seems to be taking the tech in the right direction. Your point is warranted that it may be tough for them to get a premium price on their laptops, at least in the first run through, so they will need to take some lumps up front. Next year (if as they quoted in the videos) if they are able to get some netbooks optimized for their screens with much better battery life they should be able to get at least a slight premium on their price which will make their investment worth it. |

Perhaps even MID's and cellphones could benefit from it as well!

Hopefully that is the case and within reasonable limits for other displays. |

The fact is they did not show the three modes.
At no moment did they tell us clearly: here is mode 1, now is mode 2, now is mode 3. I think they are either not very good at precisely demonstrating their interesting new screen, or they do not want to show the darkest mode, because their screen may then appear as too dark compared to the Kindle; the risk would be that it could be labeled as the "dark crap". So when do we get a clear demo of the three modes? Because I may want one in my next laptop, especially if the e-reader mode is clear enough. But even if that mode is too dark, the fact that this screen is very readable under the sun is a great advantage over my current laptop, which is totally unreadable outdoors, and prevents me from watching movies in a garden for example, a thing I found very frustrating the first time, and which led me to use it less. |
