[AG-TECH] Multi-Headed Display

[Steve Cutchin]

We at SDSC have something you might want to check out.  It fixes the color
calibration problem
and I believe provides the seamless lineup that you want.

Let me know what you think, or if it appears interesting to you.

    There is a company, National Display Systems, that makes these tiled
displays that are ready out of the box.  They are intended to be used as you
describe the panels that you are putting together.  They end up with about a
1" mullion and are VESA compliant for mounts.  Of course with this solution
you do not have the fun of ripping the plastic off your monitors but it
makes for a nice display.


  I've seen National Display before. They are really popular with the NYSE
and other stock displays. There are plenty of commercial vendors for these
LCD tiled displays, but I think the primary motivating factor for ripping
plastic or buying unpackaged displays is cost. I think EVL gets the mullion
down to considerably < 1" too. Otherwise, there are plenty of commercial
vendors who do this (just not cheaply).


    Has anybody seen a real seamless system (zero mullion)?  For the
applications that I am running I can not tolerate the loss of pixel data
required to do edge blending.  That is what I mean by real.


  Well, the Barco rear-projection/Atlas displays have a 0.3mm mullion (1/3
of a pixel). Thats about as close to zero as I've seen. It doesn't fix the
color calibration problem though....(never will).
