An LED wall is a display technology that uses light-emitting diodes to create visual content. These diodes emit light when an electric current passes through them. LED walls are composed of individual LED modules that work together to display images, videos, and other content. There are 40,000 of these LEDs in every single 500mm x 500mm panel of our Absen 2.5 stock! 

LED wall power consumption depends on factors like the screen size, resolution, and brightness settings. To help you calculate consumption, we have built our useful interactive calculator to help guide you on key information. 

Ensure the venue have a sufficient power supply for an LED wall, depending on size and other technical equipment in-use at the event, you’d probably like to enquire if they have a 32a 3phase, 63a 3phase or ideally a 125a 3phase supply available in the space where the LED wall/s are being built. We do also stock all the various power distribution options required to power the kit too. Get in touch to find out more. 

Work with a qualified electrician to ensure proper grounding of the LED wall and associated equipment. Install residual current devices (RCDs) or ground fault circuit interrupters (GFCIs) to detect and prevent earth leakage.  Our handy calculator above gives an insight into how much earth leakage you might expect.

The physical size and weight of the LED wall can affect the venue’s layout, seating arrangements, and overall event design. Consider the available space, viewing angles, and audience size when selecting an LED wall size. Smaller events might require smaller walls, while larger events might benefit from larger and more immersive displays. Our Absen LED walls only require 1meter of depth behind the wall when being ground-rigged, this helps save space when it’s at a premium! We can always assist with CAD plan drawings to help you visualise the space the wall would take up and plot your audience/furniture etc too. 

Check with the venue management regarding and load-in / installation restrictions. Consider factors such as load-bearing capacities, structural support, and obstruction of emergency exits or sightlines.  

As with all technical equipment, things can go wrong in rare circumstances. Luckily, our team are always thinking ahead about the best redundancy options and minimising and issues for your special event.  

We will always suggest supplying an automatic backup controller for example so that if one controller or data cable should fail, the data flow is immediately and unnoticeable reversed to the redundant controller – your audience wouldn’t even notice! 

Should an LED module fail during the event then we can quickly swap it out from either the front or rear of the wall by simply popping it out from its housing and inserting a new one. The LED module automatically picks up the screen configuration including brightness/colour settings and your wall is back to its correct self. 

Input types and hardware to play back content is slightly dependent on what size wall you are after. For example, a standard ratio 16:9 wall (such as a 4.5m x 2.5m size) can run on one of our smaller HD controllers which can easily scale a video input on either DVI, SDI or HDMI from a source such as a laptop. 

For larger events and unconventional ratio walls (such as a 20m wide x 4m high wall pictured above), you might need input switching and scaling capabilities and so utilising a video processor such as our Barco E2 would be advised. This can then take a whole host of inputs via SDI, HDMI and DVI and output them across multiple screens at different scales/resolutions. 

We also stock an array of playback devices from MacBook Pros to Media Servers to best suit the content type. 

Our LED walls can either be ground-supported (directly on the floor or on top of staging deck for additional height), or flown on appropriate truss/motors. 

Our expert team can help with load calculations / technical drawings in order to best make use of space for rigging. 

Typically, we find flying LED wall on truss can be slightly quicker than ground-stacking as it is quicker to get an initial level line to ensure a smooth build with no joins visible etc. However, whether flown or ground-supported, once a level surface has been created on the LED rigging system – the wall can be built fairly swiftly by competent technicians. For most walls, you should expect to allow 3-4 hours for it to be built, cabled, calibrated and tested.
