Led sports event screen classification and design considerations
Aug 30, 2021
LED sports event screens have become necessary facilities in modern large stadiums, especially for some important events: 2008 Beijing Olympic Games, 2012 European Championship and NBA games. So what are the common LED sports event screens? What should be paid attention to during their design and installation? Today, Lianchengfa Group will take you to know about it.
LED sports event screen classification:
Led sports event screen is generally divided into two parts: dot matrix and timing. Computer network control system is used for data processing, controlling the large screen display content and providing real-time information for network system and broadcast and TELEVISION system. Special competition evaluation system is the basic infrastructure for obtaining the basic scoring data of various sports competitions.
1. Large full-color LED screen
It is used to broadcast the highlights of the match (including other matches), or replay the close-ups of the match in slow motion, or express the match and a certain event with 3d animation.
2. The LED screen of the fence
The LED display beside the court is not only used to play commercials, but also to replay the highlights of the scene, so that every highlight moment can be carefully remembered.
Led fence screen is made up of a lot of single box body connected, the weight of each box body control, box body through the buckle type connection, such a design can be quickly and easily disassembled, easy to maintain. Behind each box is a separate support foot, through which the Angle between the screen and the ground can be adjusted to ensure the viewing Angle of the audience.
3. LED screen for timing and scoring
It is connected with the timing and scoring system of the competition, and plays the results and relevant information of the players. From the perspective of the competition, the timing and scoring screen is more important. Some stadiums can not have a large video screen, but also can not have a screen for timing and scoring. Timing scoring screen, the key is real-time accurate clear, and on this basis as far as possible to achieve vivid and stronger expressive (such as animation, etc.).
The scoring screen mainly displays the results, data or other information of the players in the form of text or text plus graphics and animation. The color can be monochromatic, polychromatic, or panchromatic.
Notes for LED Sports Event Screen design:
1. Security and reliability
The safety performance of the stadium equipment should be the first place because of the large crowd density. Generally, the safety performance of led display screen in stadiums should meet the requirements of 5.4 in SJ/T11141-2003 standard, and the reliability should meet the requirements of 5.10 in the standard. In terms of material selection, polymer materials with good flame retardant performance should be selected (including LED module shell, LED module filling glue, PCB board, power cable sheath, etc.). Meanwhile, in terms of power supply design, THE LED display screen of stadiums should be powered independently and meet the requirements of 5.8 in SJ/T11141-2003 standard. Cable line construction acceptance shall meet the requirements of GB50168 and GB50171; The engineering quality should meet the requirements of GB50303. In addition, sports events LED display screen should have smoke sense, lightning protection, automatic fire alarm and automatic screen off function, power distribution cabinet should have overload protection function, leakage protection function and step by step power on function.
2, installation position and quantity requirements.
The installation position of led display screen for sports events should ensure that more than 95% of the audience with fixed seats in the stadium can effectively watch, with wide visual range.
At the same time, it is required that the CONTENT of led display screen can be easily and clearly seen by athletes, coaches and referees on the spot (except for the referees who score on the spot in diving competitions).
3. Maximum line-of-sight and character height requirements.
Outdoor sports events LED display brightness requirements of more than 5000CD/square meter;
Dual primary color display 4000cd/ square meter; Monochrome 2000CD, square meters above.
Indoor stadiums full color LED display brightness requirements of more than 1000CD/square meter;
Double primary color LED display 300CD/square meter; Monochrome 120 CD/square meter or more. At the same time, in terms of character height requirements, each character of led display screen of swimming pool and diving pool with independent building structure shall be at least 0.2m, and each character of LED display screen of swimming pool with integrated building structure shall be at least 0.28m.
4. Optical performance requirements.
Led display screen for sports events requires wide viewing Angle, large visual distance, uniform brightness and adjustable. When the background illumination is less than 20lx, the led display should have a contrast of 100E1. White field color coordinates can be adjusted within 5000K-9500K according to the use environment. According to CIE1931 chrominance system, the tolerance is △ X ∣≦0.030,∣△ Y ∣≦0.030.
5. Display content can be controlled in real time.
Require rolling timings that display the game in real time; Scrolling competition results can be displayed; Can turn the page to display the competition results; The displayed text content can be switched automatically or manually. For full-color LED display with graphic and video display functions, text and pictures, animation, live broadcast images should be able to automatically and manually switch between each other.
In addition, it is worth noting that the display system of the stadium should be able to clearly, timely and accurately display the information of the sports match, and display the real situation of the match through multimedia technology, setting off and creating a tense and enthusiastic atmosphere of the match. At the same time, the system is required to have a simple, accurate, fast, user-friendly man-machine interface, support a variety of sports events, in line with the rules of sports events, easy to maintain and upgrade.
