What technical requirements should the LED stadium screen meet?

LED display is widely used in many industries, including sports industry, due to its energy-saving and environmental protection characteristics. Take the football match as an example. When watching live TV or experiencing the scene in person, the audience will certainly notice the LED displays around the major stadiums. They activate the scene, present the details of the game, and bring some advertising revenue to the main organizers. What technical requirements should these supporting LED field screens meet for high specification football matches?

Judging from the basic technical performance, such as brightness, visibility, protection level, heat dissipation, etc., the LED stadium screen is not fundamentally different from the outdoor display screen in other industries. However, from the professional direction of football sports events, the LED stadium screen emphasizes the real-time, accurate, fast and distortion free dynamic information release (highlight playback, live broadcast). In addition to wide viewing angle and high gray scale, it is generally recommended to achieve a refresh rate of no less than 3840Hz from the technical parameters, integrate high-performance driver chips, static scanning, and the live broadcast and shooting of images should be stable and tear free.

 In order to meet the informatization of the global stadium, LED screens are set up in the parking lot, the referee area, the athletes' lounge and even the functional areas of the stadium, except for the outdoor home court. In order to realize the concept of "people-oriented", the following functions should be followed in the design of the stadium screen: 

1、 Anti collision module design: easy to disassemble/show humanistic care for players 

As the stadium screen is usually in the leasing scene, it is required to be disassembled and replaced quickly and stably. Interlocking device is usually used between splicing cases, which is convenient for module installation and disassembly, and also solves the problem of seamless splicing in a large area. 

In view of the great differences in the geographical climate of many event areas, in addition to the protection and quick maintenance of the box unit module, such as moisture and water resistance, the screen surface is designed with a soft mask to ensure that it is still clearly visible under direct sunlight. High strength anti-collision devices are used in many parts of the chassis to protect players from injury, which reflects the humanistic care of the new LED stadium display solution.

2、 Viewers/referees/organizers: 

(1) Better display effect with retractable support device 

In order to achieve good display, the bottom of some high specification court screens provides a unique lifting type retractable support device. The support can be adjusted in the fixed range, making it more stable to stand, and satisfying the good display effect in different directions. 

(2) Integrated multi-function, customized split display screen 

Taking the newly added referee video assistant system in foreign competitions in recent years as an example, it can realize real-time screen review, recording and broadcasting, so as to more accurately deal with disputes, judgments, goal line scores, etc. 

The new LED stadium screen integrates professional timing scoreboards, sports video information, and even attached advertising and entertainment. It can display multiple screens, support remote monitoring, and seamlessly intersperse advertising during live broadcast of the event. It realizes the division and customization of different functional areas in different regions, and ensures reasonable advertising or value-added service revenue.

 (3) Multiple installation methods, wider application 

In addition, different functional areas around the stadium should be equipped with stadium LED display products with different point spacing, and support wall mounting, seat mounting, and hoisting to meet the application scenarios or other functional requirements around fence screens, indoor splicing walls, and many different green fields.

PANAVISUAL shared some technical requirements for a good LED stadium screen, hoping to help you.
