WSJ: Google X Display Team Works Toward Bezel-Free Modular Displays
The Wall Street Journal reports in a paywalled article that a team under Pixel Qi founder and OLPC co-founder Mary Lou Jepsen at Google's skunkwork labs Google X is working on modular video displays that could be expanded by snapping them together "like Lego." Ars Technica, TechSpot, The Verge, and several others summarize the claims made by "three people familiar with the project"; here's a snippet from TechSpot's version:
Even in the home and office, the use of multiple displays isn’t uncommon but just like with larger implementations often used for advertising purposes, screen bezels are always a problem. Bezels are less visible from a distance but up close, they pretty much ruin the experience.
The scope and target audience for the project is unclear at this hour as we are told the project is currently in an early stage. One of the biggest challenges is figuring out how to stitch images together across screens, both electronically and through software.

Great article i bet, shame i'am too fucking tight to give you 20p to read it.
This is how video walls are made. Not news. Doesn't matter. Btw I still haven't forgotten the day this site died.

Umm, Every OS on the market already does this when you hook multiple monitors up to it.
Troll is not a replacement for I disagree.
I wonder how the group plans to stitch together multiple displays seamlessly. Removing the bezel is only part of the problem. There'd still be a noticeable seam between panels, never mind the problem of lining up pixels. I suppose one could argue that beyond a certain pixel density - +400dpi or something - lining up pixels exactly wouldn't be necessary. But then you'd have to offset by that difference, and the joined panel would have to test for and respond to that offset to compensate.
I think most would be rightly skeptical of this until seeing the tech work first hand.
On another subject, at the Techspot article there was a link to the Ars project. It's some kind of hot swappable modular phone in development.

According to that, you can't swap out CPU or display live but just about everything else would be hot swappable. It's got a nifty photo showing parts to some kind of mock up or beta device.
All I could think of when looking at this was Stringer Bell from The Wire swapping out sim cards in his phone and what a boon that might be for criminals. Or at least crime drama on TV.
Ok current ones are lower res but in a few generations, Oculus Rift will be high enough res to make this obsolete. It won't be just a few monitors in front of you, it'll be 360 degrees everywhere you look. Just like being totally surrounded by displays, but without the massive expense and desk real estate needed. Use it anywhere, on your couch, whatever.
Think about coding and you could be surrounded by code. Gaming, total immersion. Etc.
Who needs monitors when you could have that?

That sounds more like the whole damned problem and not a challenge.
I get the sense that these folks want to eliminate the non-pixel space between adjacent LCD screens. That will take some fancy screen design, as the connections to the controller chips occur at the edges of the glass. Those connections are currently many pixels wide.
I imagine that someone will figure out a way, but I won't hold my breath.
The determined Real Programmer can write Fortran programs in any language.
You know what's harder than lining up the pixels perfectly on adjacent panels? Getting the brightness, contrast, color, and gamma matched. It's not as noticable when screens are separated on your desk, but put them side by side and all those little hot and cold spots are going to create a very noticable demarcation line at the seam.
I'm an individual! Just like everyone else!
On corners that give screens relation to other screen.
Yeah, it's actually quite an annoyance - we got multimonitors at work, and it drove me up the wall that one was bluer than another. So you'd have two Explorer windows open, and one was tinged a different color. Especially annoying when you have windows spanning the gap (either due to coding flaws or when moving a window to the other monitor) and it takes the tinge.
Took me an hour to get two seemingly-identical Dell monitors to be well, matched enough to not drive me up the wall. And we're talking about a 1" split with the bezel.

Basically you glue on gold slivers of plastic film, and over time mechanical bonds break or stop conducting.
And as said above, different batches have different qualities.
If Google is involved with this then you can be assured these monitors will also have cameras and mics built in and aimed at you. For anonymous analytics of course...
Yes, color correction devices exist. However, to perform a really good calibration on an ordinary monitor takes about nine tests which take ten to thirty minutes each depending on how frisky your device is feeling that day. You're going to have to do that for every single panel in the set.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Would it be possible to develop a very thin bezel free display that you could overlay on top of regular bezel displays. That thin display would be used to display the missing pixels that would be directly underneath this thin display.
I imagine that it would be easier to make a small bezel free display rather than large ones.
Of course, matching colours, brightness, etc. would be a challenge, but I think I've seen solutions to this with multiple projectors being used and the software automatically adjusts for the edges where the output of the two projectors overlap.
That's going to upset some people over at r/bezels.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
We already have screens too wide, unable to present a readable document which is taller than it is wide. Great for widescreen movies and certain spreadsheets, not so good for letters, legal papers, business documents, books or magazines.
We may have to stack these monitors somehow.

This. 3x1 setup, identical monitors. One's an infuriating shade of pink about 25% of the time. Can't for the life of me figure out why the color is off after a switch from 3x1 to 1x1 or Eyefinity, or between power cyclings. Somehow the monitor, the OS, and the video card decide to do me a "favor". The analog days were a bitch, but at least once you got a CRT set up it stayed set up the way you left it.
Professional color printing setups (workstation, printer and scanner/camera) had a self-calibrating setup where the user would cycle through photographing the screen, printing out the screen image and scanning it back again.
It would seem practical to use a single HD webcam to calibrate all the monitors in this way.
Google going Lego in display innovation
"One of the biggest challenges is figuring out how to stitch images together across screens, both electronically and through software."
I'm not discounting the intelligence of the designers at Google, but splitting video of any resolution across multiple monitors is not something that needs to be figured out. Christy, Green Hippo, Derivative and dozens of others have been offering solutions to this for years, if not decades. The finest pitch LED screens are about 5mm, these days (I'm talking about the big screens behind [yer favorite rock star], not desktops) and the gaps between the panels are essentially invisible. And solutions abound for color/contrast/brightness/gamma normalization.
There is certainly work to be done with consumer/professional displays meant for the desktop, but if you've got the money to bolt together a couple of monitors and you expect the join to be invisible, you've probably got the money to buy a bigger monitor.
Unless, of course, you're going to shape it like a windshield and stick it on the inside of your car. I don't recall seeing that at any trade shows yet.

Get a new cable, that will probably fix it. And it's magenta, not pink.
chris watts íë¦ìS ì(TM)ì
Yeah, get one of those Monster cables with gold plating and thick rubber coating. And remember to plug the HDMI end marked monitor into the monitor and not the other way around. They are made so that electrons flow easier in one direction than the other.
It would seem practical to use a single HD webcam to calibrate all the monitors in this way.
Might work if you calibrate the webcam before each run. But you'll need an ideal setup...
