Gymnasium LED display classification and installation considerations

LED displays are essential in the facilities of stadiums, allowing the audience to understand the progress of the game, score, commentary, etc. more intuitively. So what are the common stadium LED screens? What should we pay attention to when installing them?

LED sports event screen classification.

LED sports event screen is generally divided into two parts: dot matrix and timing, computer network control system for data processing, control the content of the large screen display, to provide instant information for the network system and radio and television systems; special game judging system is the infrastructure for all kinds of sports competitions to obtain basic scoring information.

1. Full-color LED big screen

It is used to broadcast the wonderful scenes on the field of play (including other fields), or slow-motion replay of live wonderful close-up shots, etc., or to show the race and a certain event in 3D animation, etc.

2. LED fence screen

LED fence screen is made of many single boxes connected, for each box weight control, between the box through the snap-on connectors, such a design to achieve the manual can be quickly and simply disassembled, easy maintenance. Each box has a separate support foot behind, through the support foot can adjust the angle of the screen body and the ground, to ensure the audience viewing angle.

3. Timing and scoring LED screen

It is connected to the timing and scoring system of the competition, playing the contestant's race results and related information, in the sense of the competition, timing and scoring screen is more important, some venues can not have a large video screen, but also can not be without the screen used for timing and scoring. Timing and scoring screen, the key is instantly accurate and clear, and on this basis as vivid and more expressive (such as animation, etc.). The scoring screen is mainly text or text plus graphic animation to display the player's race results, information, or other information. The colors can be monochrome, multicolor, or full color.

LED sports event screen design considerations.

1. Safety and reliability

Stadium crowd density and the safety performance of its stadium equipment use should be put in the first place. In general, the safety performance of the stadium-led display should meet the requirements of SJ/T11141-2003 standard 5.4, and reliability to meet the requirements of the standard 5.10. Material selection, the requirement to choose good flame retardant polymer materials (including LED module shell, LED module filling rubber, PCB board, power line sheathing, etc.), while in the power supply design, stadium led display shall be separately powered and meet the SJ/T11141-2003 standard 5.8 requirements; cable line construction acceptance needs to meet the GB50168, GB50171 requirements; project quality should be in line with the requirements of GB50303. In addition, the sports event led display should have smoke detection, lightning protection, automatic fire alarm, and automatic screen shutdown function, power distribution cabinet should have an overload protection function, leakage protection function, and step-up power function.

2, the installation location and the number of requirements.

Sports event-led display installation location needs to ensure that more than 95% of the audience in fixed seats in the arena can effectively watch, sight distance, and visual width. At the same time requires led display screen display content can make the game site athletes, coaches, and referees (except for the diving competition in the field scoring referees) able to easily and clearly see.

3. Maximum view distance and character height requirements.

Outdoor sports event led display brightness requirements 5000cd / square meters or more; dual color display 4000cd / square meters or more; monochrome 2000cd, square meters or more. Indoor stadium full-color led display brightness requirements of 1000cd / square meters or more; dual-basic led display 300cd / square meters or more; monochrome 120 cd / square meters or more. At the same time in the character height requirements, the building structure independent swimming and diving pool led display each character at least higher than 0.2m, building structure one swimming and diving pool led display each character at least higher than 0.28m.

4. Optical performance requirements.

Sports event led display perspective requirements wide, visual distance from the visual large, uniform and adjustable brightness. In the background illumination is less than 20lx, led display contrast should be able to reach 100e1. White field color coordinates according to the use of the environment within the color temperature 5000K-9500K adjustable, according to CIE1931 chromaticity system, tolerance △ x ∣ ≦ 0.030,∣ △ y ∣ ≦ 0.030.

5. The display content can be controlled in real-time.

It is required to have a real-time display of the scrolling timing of the race; it can display the scrolling race results; it can turn the page to display the race results; the displayed text content can be switched automatically and manually. For full-color led display with graphics and video display function, text and pictures, animation, and live images should be able to automatically and manually switch between each other.  

It is also worth noting that: the stadium display system should be able to clearly, timely and accurately display the information of the sports competition, through multimedia technology to display the actual game, to set up and create a tense, warm atmosphere of the game. At the same time, the system is required to have a simple and clear, accurate and fast, easy to operate the human-machine interface, support a variety of sports competition projects, in line with the requirements of the rules of various sports competitions, and easy to maintain and upgrade.
