OLPC to use Pixel Qi 3Qi screens

A cross-licencing deal between the One Laptop Per Child non-profit and Pixel Qi has been announced in this press release:

As a result of the agreement, OLPC receives full license to all Pixel Qi “3qi” screen technology, including 70+ patents in process and all current and future IP developed by Pixel Qi for multi-mode screens. Pixel Qi is leading the design of new screens for OLPC’s next-generation XO laptops.

“A huge barrier to getting computers to mass use in the developing world is limited access to electricity. Pixel Qi is designing new screens for OLPC that will keep laptops going even longer between recharges and excel in long-form reading while providing color and video,” said Nicholas Negroponte, founder and chairman of One Laptop per Child.

Mary Lou Jepsen, founder and CEO of Pixel Qi, added, “OLPC’s focus on the need for low-cost, low-power devices led me to invent power-efficient LCD screens that are optimized for reading. Commercial tablets, notebook computers and smart phones have precisely the same needs. This is one of the few examples in which cutting-edge computer technology first deployed for developing nations benefits the developed world as well.”

A few questions I would have about this awesome partnership:

1. Will a version of XO 1.5 come with the 10" 3Qi screen in the same form factor design?

2. If 3Qi only comes to OLPC starting with the ARM Powered XO 1.75, will it come in the 10" size or will they cut a smaller 7.5" version of it? My guess is to keep the costs low, they will pick the mass produced 10" size there, and fit it inside of the same design just removing most of the screen bezel.

3. I can't wait to learn what power consumption the XO 1.75 and XO 3.0 can run at using the Pixel Qi screen. Does it now run 50 hours on a battery? How much better are ARM Powered laptops like the XO 1.75 and ARM Powered tablets like the XO 3.0 at implementing the DCON processor process where the main processor can turn itself off completely when not in use?

4. Can anyone confirm that we will soon see Pixel Qi in the Marvell Moby Tablet project? Thus sooner see some implementation of tablets for education leading to the full release of the XO 3.0 tablet.

Look perhaps for some answers at Mary-Lou Jepsen's blog. Watch again some of my many Pixel Qi videos:

Samsung Galaxy S, 4″ Super AMOLED Android phone

Posted by Charbax – March 23, 2010

I filmed some Super AMOLED videos last month at the Mobile World Congress:
http://armdevices.net/2010/02/17/samsung-beam-android-phone-projector-at-mobile-world-congress-2010/
http://armdevices.net/2010/02/15/samsung-super-amoled-screen-technology/

Super AMOLED is spectacular, that's for sure. Blacks are incredibly black and vivid colors and brightness is super. The Super AMOLED is officially 20% birghter and reflects 80% less light than the first generation AMOLED screens, it removes some kind of layer that was covering the screen so devices can be thinner and the angle of vision is incredible.

Yet, my question is how much more does Super AMOLED cost compared to LCD, especially at sizes larger than 4" in diagonal. I guess this is a matter of Samsung having invested huge amounts of billions of dollars into developing the AMOLED technology, that they have to try to mass manufacture those screens in quantities of millions for them to get down in cost. I wonder though, what is the difference in cost between AMOLED and LCD in those screen sizes? Anyone who knows the bill of material, please post in the comments.

I probably don't really like Samsung's attempt at making a different UI layer on top of Android which they call "S Life UI". With the bit that I played with it on the Samsung Beam, I would probably prefer to disable that and somehow enable a normal standard Google Experience user interface.

IDTI $300 21,5″ 1080p Touch Screen

Posted by Charbax – March 17, 2010

IDTI, which I filmed their early prototypes at last year's Computex, is now showing this finalized implementation of their technology in this touch screen product which is a 21,5" 1080p screen that integrates their specific stylus based touch screen technology. IDTI's touch screen technology claims to provide same visibility as capacitive screens but for a price closer to resistive screens, though it only works using their stylus.

Liquavista sunlight readable color e-reader displays

Posted by Charbax – March 5, 2010

Liquavista is demonstrating a new type of screen technology which could provide very low power black and white and color screens based on the LCD manufacturing process, though where the screen refresh rates can be automatically turned down below 1hz. Together with Pixel Qi http://armdevices.net/2010/01/08/charbax-tests-pixel-qi-at-ces-2010/ or as an alternative, this type of LCD screen technology will enable all Tablets and Laptops to also become full e-readers and could in theory have 50-100 hours battery runtime or longer.

Aiptek 3D camera and 3D screen

Aiptek is showing probably one of the cheapest 3D camcorders on the market so far. It films 3D at VGA resolution, to then watch on any TV using polarized auto-shutter 3D glasses (or however they are called).

Motorola Head-mounted Computer Gen.2 Kopin Golden-i

Posted by Charbax – February 22, 2010

Imagine walking around with a head-mounted 15" display to view informations available to you at all times. This system features a pretty cool six-axis position tracker from Hillcrest Labs that allows you to operate a cursor with nearly pixel-for-pixel accuracy by just moving around your head when for example panning around a large image or a map. There is a highly targetted microphone that understands voice-commands where you can for example zoom in on maps or images, you can exit back to the programs menu, launch specific applications and open specific files.

Here are the specs of this Second Generation Kopin Golden-i Motorola-branded Head-mounted Computer system:

Processor -- TI OMAP3530 clocked at 600MHz
Display -- Kopin SVGA (800 x 600) liquid crystal micro display (LCD)
Networking:
Bluetooth 2.0
WiFi -- "Will be offered soon"
User interface -- Includes speech recognition and motion sensing
Other I/O -- 1 x USB
Expansion -- microSD slot
Power -- 1200 mAh battery provides more than eight hours of operation
Weight -- 3 oz (85g)
Operating system -- Windows CE
