Introduction to HD Video Walls
When most people think of screens they think in terms of pixels and
diagonal measurements. But in the not-too-distant future they will
use a new lexicon and a different set of criteria to describe it.
Flat-screen LCDs are no longer just dumb displays. They already are
powerful embedded controller in their own right, able to process
massive amounts of data and adjust it quickly enough to maximize
picture quality. In addition to getting larger, faster, more modular
and far more energy efficient, they also will begin to add a new
dimension of gap which measured from edge to edge and these screens
are already making their way into industry trade shows, but what
comes next gets even more interesting. Tilling with multi-display &
“daisy chain technology” is one of several approaches to making a
large seamless display.
Tiling display or video wall is being used in some of the largest
LCD screens today. A better is to create tiles that can fit together
almost seamlessly to create a single display by using some fast
interconnects and powerful processing.
“It used to be a race to build the largest display, but we ran into
problems of how to ship and install those displays,” says LCD
industry expert. “Today the emphasis has changed to displays that
can be tiled with a super narrow bezel to keep the edge of the
display as thin as possible. That allows you to create mega HD
displays as big as 100 feet.” |
