Mae sgriniau arddangos dan arweiniad Stadiwm yn bennaf yn arddangos digwyddiadau byw, amser gêm, sgorio, hysbysebion noddwyr, ac ati, ac fe'u dosberthir yn gyffredinol y tu mewn a'r tu allan i'r stadiwm. Gall wneud i'r gynulleidfa deimlo effaith ysgytwol iawn, gyda phrofiad gweledol a mwynhad gwahanol.
Ar hyn o bryd, mae yna lawer o ddigwyddiadau chwaraeon rhyngwladol a domestig, megis NBA, Gemau Olympaidd, Cwpan Ewropeaidd, ac ati, sgriniau arddangos LED bron yn mynd law yn llaw â stadia. Mae'r system arddangos sgrin fawr LED wedi disodli'r goleuadau traddodiadol a sgriniau arddangos CRT ac mae wedi dod yn un o'r cyfleusterau angenrheidiol ar gyfer lleoliadau chwaraeon modern. Heddiw, rydym yn dod i ddeall pa ofynion penodol sydd eu hangen ar gyfer yr arddangosfa dan arweiniad stadiwm.
1. The safety and stability of the stadium led screen should be high
In public places, safety is paramount, and there are many people watching sports games and large-scale events. Any failure or error will have a great impact, so stable engineering quality is the objective requirement of users.
Er enghraifft, bydd defnyddio trosglwyddiad ffibr optegol yn osgoi gwanhau signal ac ni fydd yn gohirio'r llun byw neu ail-ddarlledu. Gellir defnyddio rhai padiau amddiffynnol a mesurau eraill hefyd i atal damweiniau diogelwch. Gallwch ddefnyddio cyflenwadau pŵer deuol. Pan fydd un cyflenwad pŵer yn methu, gellir cysylltu'r llall yn awtomatig heb effeithio ar arddangosfa arferol y sgrin fawr LED.
2, the stadium led screen needs to support multiple input interfaces
The stadium's large LED screen can not only be broadcast live by cameras, but also broadcast TV and satellite TV programs, play VCD, DVD, LD and various self-made video signal programs, support PAL, NTSC and other formats, and display content can also be a computer Various graphics, text and video information on the Internet 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 level, protection level and heat dissipation performance of stadium led electronic display screens are better, especially for outdoor sports events, which need to take into account the changeable climatic environment. For example, southern my country focuses on anti-tide, high-altitude areas are resistant to cold, while desert areas need to consider heat dissipation issues.
4, the stadium led large screen needs a wider viewing angle and a higher refresh rate to ensure the clarity of the video display. Especially when introducing player information, scores, slow-motion replays, highlights, slow-motion replays, close-ups and other live broadcasts, it is necessary to consider whether the audience can see clearly.
5, the stadium full-color led display should select the corresponding dot pitch according to the viewing distance, such as outdoor large stadiums, generally choose the larger dot pitch display. P6 and P8 are two common dot pitches in outdoor stadiums. For indoor viewers, the viewing density is higher and the viewing distance is closer, so P4 and P5 are more appropriate for the dot pitch.
