With more and more LED display screens being used in sports stadiums, the installation and design of sports stadiums LED display screens have become a hot topic for venues and LED display manufacturers. Today, SightLED summarizes the installation and design requirements.

The design and installation requirements of LED display screens in sports stadiums

Safety and reliability:

Sports stadiums are usually densely populated, and once a safety accident occurs, the consequences will be disastrous. Therefore, we should put the safety of multi-sided LED display first. Generally speaking, the safety performance of LED display screens should strictly comply with the requirements of 5.4 in the SJ/T11141-2003 standard, and the reliability should comply with the requirements of 5.10 in the standard.

In terms of material selection, we should give priority to polymer materials with good flame retardant properties. These materials cover various components such as LED module housing, LED module filling glue, PCB board, power cord sheath, etc. Because good flame retardant properties can reduce the risk of fire to ensure the life safety of people in the venue.

Power supply design is also a key link. The stadium LED display screen must be powered separately and meet the requirements of 5.8 in the SJ/T11141-2003 standard.

Why? Because separate power supply can avoid the normal operation of the LED display screen affected by the failure of other equipment. It can also better control the power supply quality and make the display screen work stably. In the acceptance of cable line construction, we must strictly follow the requirements of GB50168 and GB50171, and the engineering quality must meet the requirements of GB50303.

In addition, the LED display screen for sports events should also have a series of safety functions. For example,

• The smoke sensing function can issue an alarm in time at the beginning of a fire;
• The lightning protection function can protect the display screen from lightning damage;
• The automatic fire alarm and automatic screen shutdown functions can quickly take measures to reduce losses when a fire occurs.
• In terms of the distribution cabinet, it should have overload protection function, leakage protection function and step-by-step power-on function.
• Overload protection can prevent excessive current from damaging the equipment;
• Leakage protection can ensure personnel safety, and step-by-step power-on can reduce the impact on the power grid.

Installation location and quantity

The installation location of the sports multi-sided LED display screen for events directly affects the viewing effect of the audience. Generally speaking, the installation location needs to ensure that more than 95% of the audience in the fixed seats in the venue can watch effectively. The viewing distance should be appropriate and the vision should be wide. This means that before installing the multi-sided LED screen, you need to make detailed measurements and analyses of the layout of the venue, seat distribution, etc. to find the best installation location.

At the same time, sports multi-sided sports LED display screen should not only be clearly visible to the audience, but also to the athletes, coaches and referees at the game site. Because athletes can adjust tactics in time according to the information on the LED display screen, while coaches can better guide players, and referees can make more accurate judgments.

Maximum viewing distance and character height

Different types of stadiums have different requirements for the brightness and character height of LED displays.

This is because the outdoor ambient light is strong. If the LED display screen is not bright enough, the audience will find it difficult to see the display content clearly.

Indoor sports venues have relatively low requirements for brightness.

However, in terms of character height, each LED display screen character must be at least higher than 0.2m.

Optical performance

It is directly related to the audience’s visual experience. First of all, the viewing angle of the LED screen is required to be wide, so that no matter where the audience sits in the venue, they can see clear display content.

In addition, you also need to consider optical performance indicators such as uniform brightness and adjustable brightness;

• uniform brightness can avoid uneven brightness and darkening, which affects the viewing effect;
• adjustable brightness can be appropriately adjusted according to different ambient light to ensure the best display effect.

When the background illumination is less than 20lx, the contrast of the LED display screen should be able to reach 100:1. High contrast can make the display content clearer and more eye-catching, and improve the audience’s visual experience.

The white field chromaticity coordinates can be adjusted within the color temperature of 5000K – 9500K according to the use environment.

According to the CIE1931 colorimetric system, the tolerance is ∣△x∣≦0.030, ∣△y∣≦0.030. This can meet the color requirements of different venues and make the display content more realistic and natural.

Real-time control of display content:

The stadium multi-sided LED display screen  needs to have a real-time rolling timing function to display the game, so that the audience and athletes can keep abreast of the progress of the game. It can display rolling game results, so that everyone can grasp the results of the game in time. It can also turn the page to display the game results, so that you can view the data in more detail. The displayed text content can be switched automatically or manually, and can be flexibly adjusted according to different stages of the game and needs.

For full-color LED display screens, it should be able to switch automatically or manually content. In this way, wonderful pictures, animations, or other live broadcast images can be inserted during the game to enrich the audience’s viewing experience.

High-standard materials and high-level control technology

(I) High-standard materials

Luminescent materials are the most important materials for LED display screens, especially full-color LED display screens. They are directly related to the display effect, reliability, and life of the display screen.

The control driver chip is the guarantee of the key design of the LED screen. Due to the high technical content of this part, the level of different manufacturers is uneven. Therefore, you can choose high-quality MBI series control driver chips to improve the stability and performance of the display screen.

The switching power supply is a component with a higher failure rate in the LED display screen. You can consider Meanwell’s high-quality switching power supply. They can provide stable voltage and current, reducing failures caused by power supply problems.

(II) High-level control technology

The stadium multi-sided  LED display screen is a large facility serving competitive events. In its control technology, you need to use more advanced technology. For example:

• Static latching technology can improve the refresh rate and stability of the LED display screen;
• White balance technology can ensure that the color displayed is accurate and natural;
• Non-linear correction technology can improve the display effect of the image;
• High grayscale technology can increase the color level and expression ;
• Color uniformity technology can make the color  more uniform and consistent;
• Video processing technology can optimize the video signal and improve the display quality;
• Fast motion image compensation technology can avoid the phenomenon of smearing in fast motion images;
• Full brake control technology can achieve precise control.

Quality assurance of design, installation and commissioning

Sports stadium multi-sided  LED displays are generally used for sports competitions and large-scale activities. Any fault or error will have a great impact. Therefore, in order to meet the requirements and ensure LED screen operates stably and reliably. You must give priority to quality rather than price in design, production, installation, commissioning, and delivery.

The design, manufacture, installation, commissioning and operation of LED electronic display screens must be matched with the site plan. In addition, you should also fully consider the power supply structure of the venue. Generally speaking, the power supply should be guaranteed to work normally within the range of (220±22)V and (380±38)V. In addition, all control equipment should be concentrated in a control room, and the venue should leave access ports for control equipment at the referee seats of various competitions to facilitate the referees to operate during the competition.

For stadiums with larger venues and more than 5,000 spectator seats,  you can consider two LED display screens with an area of ​​40M². One of the screens is divided into three parts:

• the clock area
• the full-color area
• and the dual-primary color area

The other LED screen can be divided into two parts:

• the clock area
• the dual-primary color area.
