Seamless Video Walls

Posted by CmdrTaco on from the screen-the-size-of-my-wall dept.

ahfoo writes "A company called Seamless Display is shopping around a new way of hiding the seams in video walls that mostly relies on modifiying video drivers to achieve its effects. According to their press release they hide the edges between monitors with a bit of plastic film and compress the video at the edges to produce a more or less seamless image. " Really bizarre, but it looks interesting.

  2. Rear Projection by jhines0042 · · Score: 3, Interesting

    Wouldn't a video wall be better served by having several rear projectors that line up perfectly rather than trying to eliminate the frame of a CRT?

    It seems to me that with a good jig and a consistent set of projectors, and some good use of mirrors if depth is a problem, that you should be able to get a seemless image with very little work.

      You've got an extra room to devote to the task?

      I think computing paint would better serve the purpose. When will I be able to just paint a monitor onto my wall? (And I bet the fumes will be carinogenic.)

      They wouldn't have to even line them up exactly.

      I saw a demonstration using a beowulf cluster (well, part of one) that was rendering a moving 3-d CAD model. They just threw the projectors so they were somewhat aligned, used a webcam and had one of the nodes look at the overlap and correct for the projector's misalignment in real time. ~20 other CPUs were doing the rendering, but it only took one to make the display come out right. I would imagine the same thing could be done for a rear-projection screen. As long as the projectors didn't get jostled after being observed by the computer it should work fine.

  3. Possibly already an irrelevant technology by heironymouscoward · · Score: 4, Interesting

    OLEDs are almost there, they are already being used in small portable devices (cameras and phones). They can be scaled without the fabrication issues that hit CRTs and LCDs. There is a good chance that OLED screens will be the first consumer-ready wall screen system (the current best of breed being the projector).

    But this looks fun, and it may be a good stopgap. I'm wondering whether it can be used to build (for instance) large LCD monitors for PCs...? I once had a portable that used two B&W LCDs to achieve a larger display area, but I've never seen this done with color LCDs.

  4. Try draper as well by Stonent1 · · Score: 4, Interesting

    www.draper.com Back when I installed Air Traffic Control simulators we used Draper screens. I was looking at the Draper site and they said they had seemless displays and this was about a year ago. We could get pretty seemless with the large screens that we had.

  5. Oled's are they the saviour of lcd tech? by way2trivial · · Score: 3, Interesting

    after reading the pieces on CDR's which use organic dyes, and the organic dyes don't last beacuse they break down, I wonder about the long term viability of Oled's. Aren't those organic components subject to the same rules of degradation as the organic dyes?

    There's still a perceptible seam, and the span is somewhat distorted. Not the greatest for details.

  7. Technology.... by $exyNerdie · · Score: 3, Interesting


    Well, it seems that they use a lens coating to correct image corners (could be affected by wear and tear). I thought it was ONLY a software based change in display drivers.

  8. LCDs are already organic :P by purduephotog · · Score: 2, Interesting

    They use organic polymers - dyes are organic. Everything fades. Your laptop will fade. OLEDs sometime do this faster, sometimes slower.
