Due to the very high luminosity of the video wall, even the weather in the end hardly plays a role, because even in snow and rain the content is still easily recognizable due to the very bright light – and the resolution also benefits from the switch to the LED wall.
No high resolutions – and no problem
If we take a look at the resolution of the video wall, it quickly becomes clear that no great revolution is about to take place.
An LED module, as found on the LED wall, usually involves a distance of 1.2 to 32.0 millimetres between the individual RGB groups of pixels. The finer this distance, the fewer individual pixels are visible to the human eye and the more lifelike the result appears on the screens.
A typical 55-inch television with a resolution of 1,920 * 1,080 pixels (i.e.: Full-HD) already achieves a distance of only 0.63 millimetres today. If we increase the resolution to Ultra-HD and thus 3,840 * 2,160 pixels, this value is further halved. In the discipline of pixel pitch, it looks like the LED wall doesn’t look too good. However, the distance between the display and the viewer must be taken into consideration.
Sitting at a desk, you’ll still be able to count individual pixels even on a 4K screen with a 27-inch diagonal as you get closer to the display. An LED-based video wall, on the other hand, is often used outdoors, at the cinema or in other places where there is no proximity between the viewer and the screen.
In other words, even with a resolution of “only” 1080p, a person will not be able to see pixels on the video wall at these distances.
Installation of the LED screen: Where is it possible?
The LED wall is quite unrestricted in terms of its areas of application. For the installation of the LED wall these methods would be conceivable:
– Hanging on aluminium supports
Several modules can be assembled on supports of a video wall. These systems are available with different joint widths and can be fitted quite freely, depending on the size of the carrier wall. Whether you assemble an LED wall from just a handful or two dozen modules is up to you.
– Standing on stacking systems
If there is no infrastructure available for a hanging setup, you can also simply stack the video wall on top of each other. The height is limited due to physical properties (because the wall must not be allowed to fall over), but there are practically no restrictions in terms of width with regard to the dimensions of the LED screen.
– Perimeter advertising in the sports area
Similar to the stacking system, a video wall can also be implemented as a tape system. These have a somewhat more robust design and can withstand shocks if necessary without damaging the video wall. Here, too, the width of this solution is more or less unlimited, but there are restrictions in terms of height.
How and where you install the LED screen is therefore up to you. There is no such thing as a “best system”.
