Stadium LED displays mainly display live events, game time, scoring, sponsor advertisements, etc., and are usually distributed inside and outside the stadium. It can make the audience feel very shocking, with different visual experience and enjoyment.
At present, there are many international and domestic sports events, such as NBA, Olympic Games, European Cup, etc. The LED display almost matches the stadium. The large-scale LED screen display system has replaced traditional lighting and CRT display screens, and has become one of the necessary facilities in modern stadiums. Today, we are beginning to understand what specific requirements are required for stadium LED displays
1. The safety and stability of the stadium LED display must be very high
In public places, safety is paramount, and there are many people watching sports games and large-scale events. Any failures and errors will have a great impact, so stable engineering quality is an objective requirement of users.
For example, using fiber optic transmission will avoid signal attenuation and will not delay live or broadcast pictures. You can also use some protective mats and other measures to prevent safety accidents. Dual power supplies can be used. When one power supply fails, the other can be automatically connected without affecting the normal display of the large LED screen.
2. The stadium LED display needs to support multiple input interfaces
The large LED screen of the stadium can not only be played in real time through the camera, but also can play TV and satellite TV programs, play VCD, DVD, LD and various self-made video signal programs, support various formats (such as Pal), NTSC, etc. Various graphics and video information also need to be able to connect to the referee system, timing and scoring system, and the LED screen can display the game time and score in real time.
3. The flame retardant grade, protection grade and heat dissipation performance of LED electronic display screens in stadiums are better. Especially for outdoor sports, the ever-changing climatic environment needs to be considered. For example, in southern China, the focus is on moisture resistance, cold resistance in plateau areas, and heat dissipation in desert areas.
4. The large LED screen of the stadium needs a wider viewing angle and a higher refresh rate to ensure the clarity of the video display. Especially when introducing players’ information, scores, slow-motion replays, highlights, slow-motion replays, close-ups and other live broadcasts, consider whether the audience can see clearly. 5. The full-color LED display of the gymnasium should select the corresponding pixel pitch according to the viewing distance. For large outdoor stadiums, a larger pixel pitch is usually selected for display. P6 and P8 are two common pitches in outdoor stadiums. For indoor audiences, the viewing density is higher and the viewing distance is closer. P4 and P5 are more suitable.
