An LCD video wall is a large visualization surface that is built from multiple LCD displays (also known as ‘tiles’). These individual displays are designed specifically for use in these applications, and differ highly from normal television sets. The biggest differences are the bezel width, the mounting system, and the reliability. Normal television sets are designed to play a few hours per day, these specific panels are expected to play much more. Often even 24/7. And because the environments in which these video walls are deployed are sometimes critical, the uptime needs to be as high as possible.
A very important specification for LCD video walls, is the bezel width. This needs to be as thin as possible. If not, the black bezels will create a black raster that hinders the visual experience. Contemporary LCD display wall tiles have an ultra narrow bezel that lowers this effect. With Barco UniSee, we have created the LCD without any bezel, featuring the narrowest gap in the industry. This is not only because of the absence of the bezel. The specially designed wall mounting mechanism (UniSee Mount) greatly helps to guarantee a minimal gap.
Especially important for video walls, is a perfect calibration. This is not only restricted to a single panel. More critical, is that the color and brightness settings of the complete wall match. This means that the values of all panels need to be synchronized with the surrounding displays. If not, even the slightest deviation in color or brightness will make the wall seem out of balance.
In most cases, this is a time-consuming task which requires downtime. That is why Barco has developed an automatic real-time calibration system. With just a touch of a button (or scheduled at a certain time), the complete video wall will recalibrate in seconds.

LCD display systems has a number of typical advantages over other display technologies, like rear-projection and direct LED video walls.
