In order to achieve this requirement, ensure the stable and reliable operation of the display screen, and be foolproof, we must take quality as the guide in design, production, installation, debugging, and delivery, and use an effective quality assurance system to ensure the entire production process.

2. Analysis of site demand for LED display screens
   The design, manufacturing, installation, debugging and operation of LED electronic displays must be compatible with the stadium's plan and section to coordinate the overall effect. At the same time, the power supply structure of the venue should be fully considered. Generally speaking, the power supply should be ensured to operate normally within the range of(220 22) V and (380 38) V. In addition, all control equipment should be centralized in one control room, and access points for control equipment should be left at the referee seats of various competitions in the venue.

场地较大，观众座位达到 5000 个以上的体育馆，一般可建造两块面积达 40M2 的 LED 电子显示屏，其中一块屏分为时钟区、全彩色区和双基色区三部分，另一块屏可分为时钟区和双基色区两部分。This not only ensures the satisfaction of various functions, but also ensures the reasonable use of funds. If the funds are sufficient and it is possible to host large-scale gatherings or competitions in the future, you can also make the two screens into full-color screens, so that the playback effect will be more realistic and the atmosphere will be stronger.

3. Demand analysis for led display content
   The multifunctional modern gymnasium can not only be used to hold various sports competitions, but also can be used to hold various large-scale cultural and artistic activities and gatherings. Therefore, the display content requirements for the display can be summarized as rich, diverse and real-time, as follows:

• Demand for live video images: Sports competitions, cultural performances, and large-scale events held in the stadium can be broadcast live through electronic display screens, and have special effects such as panoramic views, close-ups, slow motion, flashing actions, drag images, and nostalgic movies.
• Compatibility requirements of multiple input methods: The stadium display can not only be real-color live broadcast by the camera, but also broadcast TV and satellite TV programs, play VCD, DVD, LD and various homemade video signal programs, and support PAL, NTSC, etc. Various systems, the display content can also be various graphic information on the computer, various information from the stadium's internal information network or public information network; It has the functions of superimposing text information on TV pictures, and also superimposing text, pictures, animations, etc. on video images; playing relevant background pictures during cultural performances and large-scale gatherings.
• Demand for colorful graphic and text information playback: On the one hand, the stadium display can be used for live broadcast of video images, and on the other hand, it can carry out news releases, important notices, and slogan display. The display can display text, patterns, patterns, animations, etc.; It has the function of playing pictures and texts of different proportions on the left and right at the same time.
• Requirements for multiple broadcast methods: there must be pan, scroll, rotation, swipe, pull screen, single/multi-line pan, single/multi-line up/down, left/right pull, up/down, page turning, move, rotate, zoom out, zoom in, flash, window opening and other functions. In order to hold large-scale international sports events and activities, the display screen should be compatible with various languages, such as Chinese, English, numbers and various characters, and have multiple fonts. Font type selection, text can be zoomed infinitely.
• Demand for advertising and display methods: As the most eye-catching display media in the stadium, the full-color display screen of the stadium will inevitably become the first choice for corporate publicity. Therefore, the needs of various merchants for advertising must also be fully considered in the display content needs, so that the display screen can quickly and conveniently insert corporate advertisements to meet the needs of customers.
• The need for sports competition information and sports results announcement: The release of sports competition information and results is the basic requirement for the electronic display to realize its display function. Therefore, the use requirements of various sports competitions should be fully considered in the design and competition information should be released, such as basketball, volleyball, badminton, table tennis, weightlifting, gymnastics and other competition information. Country names, team names, athlete numbers and performance records can be displayed in the results announcement; Various real-time information can be displayed during the game, such as the name of the game team, score, player scoring, substitution, player's name, number and number of fouls punished, etc.
• Clock display requirements: Another display function of the stadium display screen is required to have accurate clock display functions. The clock display functions include Beijing time, game clock, and countdown display. Different game clocks can be set according to different competition events and referee rules, and can be easily controlled. Pause, reset, fast, slow, etc.
• Demand for synchronized audio playback: The stadium display screen has an audio interface, which can be combined with the audio in the venue to achieve the audio-image synchronization function.

4. Demand analysis of LED display environment

• High brightness: Since stadium competitions and activities are held during the day or under strong lights, the display must be high brightness and be clearly visible under strong light.
• Damp-proof, anti-corrosion and heat dissipation: Due to the large size, fixed installation, and many wiring, special storage methods cannot be used. In addition, it must adapt to the humid, rainy, and high-temperature weather that may occur in the installation area, so stable and reliable use must be ensured., moisture-proof, anti-corrosion and good heat dissipation measures must be considered in design and construction. At the same time, the display screen should also be dustproof treated.
