АV LED and Video Walls
What are LED and Video Walls?
LED walls or Video walls are both massive screens used for in-indoor advertising or as digital billboards for outside advertising.
When we say Video Wall we most commonly refer to a screen that is a lot bigger than the average consumer TV set
or monitor. Unlike consumer screens, a Video Wall may be composed of many smaller screens.
These screens differ from consumer screens in a few more ways which we’ll go over in more detail below.
What’s the difference between a
commercial video wall and consumer screen?
The brightness
levels
A normal consumer screen is way less brighter than a Video Wall. Since commercial screens have to be viewed in broad daylight, which means that the brightness levels have to be way higher. LED walls are able to achieve that by having backlights that are more powerful than what you will find in your home TV or desktop monitor.
Lower power
consumption
While a normal consumer screen may only be turned on for a couple of hours a day, a commercial LED Wall may need to run for eight, twelve or even 24 hours a day. When you have a video wall made up of fifteen 50 inch screens the cost of electricity can quickly add up. This is why Video Walls are optimised to use as little power as possible.
Pixel
Pitch
Pixel pitch is a technical term that measures the space from the centre of the LED to each individual pixel. A higher pixel pitch will lead to a higher image quality. In normal consumer screens more is better, however a higher pixel pitch also means a higher price and power usage. What needs to be considered is the viewing distance.
Durability, maintenance and service ability
With consumer screens, if something breaks, whether it’s the backlight, LED panel, or the main circuit board, it’s probably time for a replacement. Commercial-grade LED and Video Walls have a much more modular design allowing for quicker servicing. As a whole, AV Video Walls are a lot more durable than normal consumer screens.
Where are LED walls and Video Walls used?
LED and Video Walls are just one component of an entire AV setup that we usually design and install.
They can be used in a wide variety of industries and they can serve a lot of purposes.
For most Audio Visual projects, the LED screen is one of the most commonly used equipment pieces.
