Outdoor LED Screens

 
Outdoor LED screens can either be fully mobile, usually housed in a truck or trailer, or they can be free standing screens built using truss frames. Both types have their particular strengths and weaknesses, and the decision over which is best for your event will usually be dependent on the venue and event type. An LED Screen is like a giant television, but with one fundamental difference: instead of the picture being beamed from a cathode ray tube, each pixel is made up of a cluster of tiny LEDs.

 

Each cluster on an LED screen has a red, green and blue LED, which light up accordingly to create the correct colour. If you look very closely at your television set then you can see individual pixels. If you look very closely at an LED screen, all you see is lots of very bright little lights, because the pixels are much bigger, but when you get further away the picture becomes clearer.

Brightness

 
LED screens use incredibly bright light emitting diodes, designed specifically to be visible in daylight. This is the key strength of LED screens. LED screens can still be easily visible with direct sunlight pointing at the screen. LCD and plasma screens suffer from direct sunlight in outdoor environments. The same goes for projectors, a very powerful projector will only be effective in a low light outdoor environment or during the night.

Resolution capability / Viewing distance

 
Physical resolution is a very important characteristic for full-colour LED screens. Resolution capability works out at the number of addressable points or pixels (the amount of LEDs in the screen). The higher the physical resolution or pixel density is, the more qualitative the picture on the LED screen is.

 

Pixel pitch is a term used when describing how far apart the LED clusters (pixels) are from each other. Meaning the closer the pixels are to each other, the closer the viewing distance becomes before it becomes pixelated. But due to working with unique LED technology of “virtual pixels” which very cleverly shares LEDs between pixels, making the optical resolution twice as high as the physical resolution. For example LED screens using this technology often give out specifications saying the actual pitch is 14mm and the virtual pitch is 7mm.

 

For most outdoor LED screens their pixel pitch is generally around the 20mm mark, which is suitable for most outdoor events because audiences are at least 5m away from the screens. Pixel pitch becomes very important when it comes to indoor screens, as audiences are generally closer. This is where high resolution screens are preferred because the viewing distances are minimal, due to having a 4-mm pixel pitch.

Ground Stacking Screens

 
The floor standing structure allows the screen to be placed directly on the floor or on a raised platform. Stepped terraces, street obstacles or locations with restricted access can be overcome using a raised platform. No power is required for construction. A small foot print, strong resilience to high winds and a clean front profile make this an ideal outdoor screen solution.

Flown Screen Systems

 
Suspended from PA wings or from hanging points. The advantages of hanging a screen from installed points are: rapid construction times, more cost effective than separate screen structure and the ability to accommodate for any screen size or aspect ratio.

Goal Post Structure

 
The goal post structure is completely free standing using Slick or Litec Truss Systems. Structurally independent of any other structure, the screen is raised from ground level using our own Loadstar motors. This system can thus accommodate any screen size or aspect ratio required.

Mobile LED Screens

 
Mobile LED screens can be ready to operate in minutes, these screens are fully independent and do not need any additional structures. After driving the trailer in position and levelling the base, the screen rises out of the trailer by a simple lever. The screens are able to turn 360 degrees allowing you to adjust the display to face your audience, whatever the setting. All the processing equipment is stored in the trailer which can input most formats for the screen. The trailers also carry an onboard generator for using the screen where no external power is available.

Outdoor Equipment is classified as to how much weather and water it can handle by an IP rating.

 
What is an IP rating?
IP (or “Ingress Protection”) ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.
What do the numbers in an IP Rating mean?

The numbers that follow IP each have a specific meaning. The first indicates the degree of protection (of people) from moving parts, as well as the protection of enclosed equipment from foreign bodies. The second defines the protection level that the enclosure enjoys from various forms of moisture (drips, sprays, submersion etc). The tables below should help make sense of it:

IP Ratings – what they mean.
IP Rated Enclosures – quick find chart
A number replaced by x indicates that the enclosure is not rated for that spec.
First Digit (intrusion protection)
0 No special protection
1 Protection from a large part of the body such as a hand (but no protection from deliberate access); from solid objects greater than 50mm in diameter.
2 Protection against fingers or other object not greater than 80mm in length and 12mm in diameter.
3 Protection from entry by tools, wires etc, with a diameter of 2.5 mm or more.
4 Protection against solid bodies larger than 1mm (eg fine tools/small etc).
5 Protected against dust that may harm equipment.
6 Totally dust tight.
Second Digit (moisture protection)
0 No protection.
1 Protection against condensation.
2 Protection against water droplets deflected up to 15° from vertical
3 Protected against spray up to 60° from vertical.
4 Protected against water spray from all directions.
5 Protection against low pressure water jets (all directions)
6 Protection against string water jets and waves.
7 Protected against temporary immersion.
8 Protected against prolonged effects of immersion under pressure.
