The LED sports event screen has become a crucial component in modern large stadiums, enhancing the spectator experience by delivering real-time scores, highlights, and visual content. But what are the different types of LED screens used in sports events, and what factors should be considered during their design and installation?
LED screens for sports events come in various forms, each serving a specific purpose. They are typically divided into two main categories: dot matrix displays and timing score boards. These systems are integrated with computer networks to process data and control the visuals, providing real-time updates for both audiences and broadcasting platforms. Additionally, they support specialized scoring systems that collect and display essential performance data.
1. **Full-Color LED Screens**
These are commonly used to show live action, slow-motion replays, or 3D animations of the game. They bring excitement to the stadium and help keep fans engaged throughout the event.
2. **LED Fence Screens**
Located around the stadium, these screens not only display advertisements but also show key moments from the field. They are made up of modular panels connected via snap-type connectors, making them easy to install and maintain. Each panel has a support foot that allows for angle adjustments, ensuring optimal viewing angles for spectators.
3. **Timing and Scoring LED Screens**
Integrated with the official scoring system, these screens display player performances, match statistics, and other relevant data. Accuracy and clarity are essential here, as these screens play a vital role in keeping everyone informed. Some stadiums may not have large video screens, but they always need a reliable timing and scoring display.
When designing and installing LED sports event screens, several key factors must be considered:
1. **Safety and Reliability**
Stadiums are high-traffic areas, so safety is the top priority. The LED screens must meet industry standards like SJ/T11141-2003, including fire resistance, lightning protection, and automatic shutdown features. Power supplies should be separate, and cables must comply with GB50168 and GB50171.
2. **Installation Location and Number**
The placement of the screen should ensure that over 95% of seated spectators can view it clearly. It should also be visible to athletes, coaches, and officials on the field.
3. **Brightness and Visibility**
Outdoor LED screens require a brightness of at least 5000 cd/m², while indoor screens need at least 1000 cd/m². Character height is also important—swimming and diving halls require a minimum of 0.2m for standalone structures and 0.28m for integrated ones.
4. **Optical Performance**
The screen should offer a wide viewing angle, uniform brightness, and adjustable settings. When ambient light is below 20lx, the contrast ratio should be at least 100:1. Color coordinates should be adjustable within the CIE1931 standard.
5. **Real-Time Content Control**
The system should allow for real-time updates, scrolling scores, and switching between text, images, and videos. This ensures that the audience always gets the latest information.
In summary, an effective LED sports event screen not only delivers clear and timely information but also enhances the overall atmosphere of the event. It should be user-friendly, adaptable to various sports, and easy to maintain and upgrade. With the right design and implementation, these screens can significantly elevate the fan experience and make every moment of the game more memorable.
