DIY Pixel Qi Screens Available 60
16384 was one of a surprising number of DIY types to note that the Pixel Qi screen is out. It can be installed in many netbooks. Can't wait to see what people build with them. An excerpt from the press release says
"MAKE and Pixel Qi announced today the availability of a revolutionary LCD display technology from Pixel Qi — the 3Qi display. This one-of-a-kind, plug-and-play 10.1-inch display offers two modes: an easy-to-read, real color, multi-media mode or a crisp, low-power e-reader mode. Indeed, the sunlight-ready e-reader mode makes it easy to use outdoors. The 3Qi display is on sale now at makershed.com."

I thought one of the advantages of the Pixel Qi screens were its low price, as it was initially targeted to the OLPC. This thing is $275.00 without an attached laptop behind it.
Is this because that's the retail price for the public at large, or are there some major differences with respect to the OLPC screen that justify the higher price?
Re: (Score:2)
Most likely, the price is so high due to a small production run.

The ruthless margin-slashers who do purchasing for the big OEMs are just going to give you a thousand-yard-stare and a hollow laugh if your quoted price is much above a standard LCD of the same size, so Pixel Qi are either utter morons, or offer much more reasonable terms in quantities of 10,000+
Plus, while the maker shed is a noble operation, and sometimes a useful place to get stuff that would be hard to find in small quantities elsewhere, they aren't what you would call an "everyday low prices" kind of operation...

For OEMs this is interesting but so dangerous.
Until they get some big product to use it they are very risky for a small company to buy.
You could design your product around the part only to be SOL when they go out of business. Molds are expensive.
I would so like to use one of these but until they are in mainstream production they are just too dangerous.
However for some one with a hacker spirit might I suggest that you combine this screen with this http://beagleboard.org/hardware-xM [beagleboard.org]

Something called unit quantities. That's the retail price for a single screen. Buy 10,000 of them and the price will be substantially lower.

They have a pretty picture [pixelqi.com] which explains the difference. Basically, the concept is the same, but the Pixel Qi displays have much better performance in trasflective and reflective modes (in terms of response times, anyway). The OLPC display is not really meant to be used for much beyond static text in reflective mode. The Pixel Qi displays are for more general use.
The advantage is not the price so much as the fact that you can use it while sitting outside in the sun, without having to squint.

This is because they don't really care about the handful of DIYers who'll buy it, they're after the OEMs. Why devalue their product by seeling it at a realistic price when they can upmark it to silly levels like that other company ?

Resolution? (Score:1)

If it's like the OLPC screen, that's a semi-difficult question. It depends on the colors in the image you are displaying, and the lighting you are viewing it under.
The OLPC's screen, in pure black-and-white mode while front-lit, has basically four times the resolution it does when in back-lit full-color mode.
Re: (Score:3, Funny)
OK, so then allow me to rephrase the question:
What are the resolutions on this thing?
Re:Resolution? (Score:5, Informative)
It is not that difficult to answer for the OLPC. The resolution of the OLPC display is 1200x900. However the difference is that unlike a normal LCD it doesn't have a RGB triplet for each pixels, but only one of R, G or B per pixel. So to display a color you need multiple pixels, instead of one. However this doesn't mean that the resolution will be lower in color mode, it will simply look more blurry, the framebuffer stays 1200x900 the whole time.
What the OLPC does is pretty similar to what you see with subpixel rendering with fonts, it just does it the other way around. So instead of gaining resolution in displaying black&white, it loses resolution when doing color rendering. But it is just blurriness, its not like you switch from 1200x900 to a crystal clear 600x450 or something like that.

"Ryan explained that Windows treats Pixel Qi’s 3qi display as a 1024 x 600 pixel screen, it’s actually a 3072 x 600 pixel screen. Those extra pixels help make the text easier to read if you’re using Roman, Cyrillic, Hebrew, Arabic, or a number of other languages. For Chinese, Pixel Qi is working on higher vertical and horizontal resolutions."

Please note: These screens replace those found in the Samsung N130 & Lenovo S10-2. Although they do work in other models, we can only guarantee compatibility on those 2 specific netbooks. We are testing other models, and will update the list as needed.
These two netbooks rank in at about $300 new, $230 used. Even after the $275 screen, one could make a pretty cool netbook with it at a good price. If one was so inclined, they could also go vacuform or lasercut a custom plastic case and turn the thing into a really powerful dual-mode e-reader.
You out there Ben Heck? Get on it!

I think it would be cool to tinker with. I could possible justify the purchase since I could use the modified laptop in direct sunlight when I'm doing magnetometer calibrations.
But $275 places it out of my DIY price range and $575 total price places it in the same price range of the cadillac of tablet devices and I would still need to make a case (and add touch screen input).

10.1 inches, replaces screens on two netbook models (Samsung N130 & Lenovo S10-2), maybe more models (they're testing), nice full-sunlight low-power "e-reader" mode that would be *great* for outdoor work (check out the comparison shots [pixelqi.com]), costs $275 USD, etc. But nowhere do they say what resolution the display is, which is a bit silly. I'm guessing 1280x800? Anyone know?

If I were you, I would probably:
1. Find out what type of motherboard is in my laptop (from asus' website). It will either be in a parts or service pdf. Or maybe find it from a retailer selling replacement parts.
2. If possible, who manufactures it
3. Find out the type of video connector on your motherboard
4. Do the same with the compatible models listed on the website.
It would probably take about 15-30 minutes to dig through the respective websites and to find the information you are looking for. A pdf or two

Curiosity question: how do you interface to it with a DIY setup? (Ie, how do you control display mode, etc?) I'm thinking this would be a fun display to use to DIY a portable unit of some sort, but I can't find any instructions for using it other than for people who are replacing the display in an existing laptop.

I expect these kind of screens to be available in a couple of years. Lets hope they finally *will* compete on resolution rather than size. Currently I'm going to settle for the HP ZR24w IPS screen. It's not perfect but it's the only 1200 line IPS screen that is reasonably priced.

Link to working prototype demo - long video with lots of info:
- b&w & color options
- video
- dynamic refresh rate (power consumtion)
- high transmissive (up to 45 per cent more than LCD)
- transmissive, transflective and reflective options
- can be build using adapted LCD manufacturing equipment
- competitive in price with LCD technology (well, that's subjective, isn't it)
I wonder how they would compare.
