The LED display screens in the stadium mainly show live event broadcasts, game times, scores, sponsor advertisements, etc. They are usually installed both inside and outside the sports venue. They can provide a very impressive effect for the spectators on the spot, offering a unique visual experience and enjoyment. 

There are many international and domestic sports events nowadays, such as NBA, the Olympics, the European Cup, etc. LED display screens are almost always present alongside sports venues. The LED large-screen display system has replaced traditional lighting and CRT displays and has become one of the essential facilities in modern sports venues. Today, let's take a look at the specific requirements for stadium LED display screens. 

1. The LED screen in the stadium should have high safety and stability performance. 

In public places, safety comes first. During sports events and large-scale activities, there are a large number of spectators. Any malfunction or error could have a significant impact. Therefore, stable engineering quality is an objective requirement of users. 

For example, using fiber optic transmission can prevent signal attenuation and avoid delays in live or broadcast images. Some protective pads and other measures can also be adopted to prevent safety accidents. Dual power supply can be used. When one power supply fails, the other can automatically connect and there will be no impact on the normal display of the LED large screen, etc. 

2. The LED screen in the stadium needs to support multiple input interfaces. 

The LED screen in the gymnasium not only can be used for real-time live broadcasts by cameras, but also can transmit TV and satellite TV programs, play VCD, DVD, LD and various self-made video signal programs. It supports various formats such as PAL and NTSC. The display content can also be various graphic, text and video information on the computer. It also needs to be able to connect the referee system and the timing and scoring system. The LED screen can display the game time and score in real time. 

3. The flame retardancy, protection level and heat dissipation performance of the LED electronic display screens in the stadium should be excellent. Especially for outdoor sports events, the variable climatic conditions need to be taken into account. For example, in southern China, emphasis is placed on resisting moisture; in plateau areas, resistance to cold is required; and in desert regions, heat dissipation issues need to be considered. 

4. The LED large screen in the gymnasium requires a wider viewing angle and a higher refresh rate to ensure the clarity of the video display. Especially during live broadcasts such as presenting athlete information, scores, slow-motion replays, exciting scenes, slow-motion replays, and close-up shots, it is necessary to consider whether the audience can clearly see and understand. 

5. For the full-color LED display screens in the stadium, the appropriate pitch (point spacing) should be selected based on the viewing distance. For outdoor large-scale stadiums, screens with a larger pitch (such as P6 or P8) are generally chosen. For indoor stadiums with higher audience density and closer viewing distances, pitches of P4 or P5 are more suitable.
