LED Screens for Music Festivals and Tours

What a touring screen has to survive

A festival screen is transport equipment as much as a display. It is built in a warehouse, trucked a long distance, flown on a truss, rained on, and struck again within a few hours of the headline set. The specification that matters most is therefore not the finest pixel pitch available but the balance between image quality, cabinet weight, weather protection, rigging load and the number of crew hours needed for load-in and load-out. A wall that assembles quickly and packs into standard flight cases will be used more, and repaired less, than a marginally sharper one that takes twice as long to build. For main stage use, outdoor rental cabinets in P3.91 or P4.81 with 500 x 500 mm panels are the working default. Cabinet maths decides the finished size: a screen is always a whole number of cabinets, so a 10 m x 5 m wall is a grid of 20 x 10 panels with no custom filler strips, while an 11 m target would leave a 500 mm gap that has to be closed with a masked column or by changing the target width. Settle that grid early, because it also fixes the number of power and data links on site.

• Pitch by audience distance: about 1 mm of pitch for every 1 m to the nearest viewer, so P3.91 where the barrier is 4 m from the stage and P4.81 or P6.67 on larger sites where the crowd starts further back.
• Brightness for daylight: outdoor screens commonly run 5,000 to 8,000 cd/m2. A stage that plays from late afternoon into the night needs the upper end for the first sets, with dimming for the darker hours.
• Refresh rate for camera work: 1,920 Hz minimum and 3,840 Hz preferred, so IMAG feeds, phone footage and broadcast cameras do not pick up scan banding.
• Weather protection: permanent outdoor installations normally use IP65 cabinets. Rental panels are often IP65 front and IP54 or IP65 rear, which is adequate for a run of shows but not for a wall left standing through a storm.
• Spares that travel with the tour: spare cabinets, receiving cards and power supplies, plus a small stock of spare data cable and quick locks.

Rigging, structure and the numbers behind it

Rental cabinets of 500 x 500 mm typically weigh 7 to 9 kg each, so a 10 m x 5 m wall is roughly 50 panels and several hundred kilograms of screen before truss, motors and rigging hardware are counted. At festivals the answer is usually ground support towers with ballast rather than a flown grid, and the structure has to be engineered for the wind speed the site expects rather than assumed from a previous event. Ladder bars and quick locks speed up the build, but the real time saver is a repeatable layout: the same cabinet order, the same power chain and the same data path every day.

Power, data and the questions to settle early

Outdoor rental screens draw roughly 500 to 800 W/m2 at peak white, so the generator and distro plan has to be agreed with the screen size, not after it. Data normally comes from a sending card with redundant feeds and a backup playback source, and the control position needs either a clear line of sight or a network link. Three answers change the cabinet choice more than the pitch does: the rigging points available, the wind speed the site is designed for, and whether the wall will be filmed. Screen price varies with specification, so those details are what a written quotation is built on.
