LED sports event screens have become a must-have for modern large-scale sports venues, especially some major events: the 2008 Beijing Olympics, the 2012 European Cup and the NBA. So what are the common LED sports event screens? What do you need to pay attention to during their design and installation? Let's take a look.
LED sports event screen classification:
The LED sports event screen is generally divided into two parts: dot matrix and timing. The computer network control system is used for data processing, controlling the display content of the large screen, providing real-time data for the network system and the broadcast television system; the special game evaluation system is various sports competitions. Get the infrastructure for basic rating data.
1. Full color LED large screen
It is used to play the scenes on the field (including other venues), or to replay lively close-ups in slow motion, or to express the game and a certain event in 3D animation.
2.LED fence screen
The LED display next to the stadium is not only used to play commercials, but also to play back the wonderful shots on the field, so that every moment can be meticulously memorized. The LED fence screen is made up of many single cabinets. The weight of each cabinet is controlled. The cabinets are connected by snap-on connectors. This design enables quick and easy assembly and disassembly and easy maintenance. Each box has a separate support foot behind it. The support foot can adjust the angle between the screen and the ground to ensure the viewing angle of the audience.
3. Timing scoring LED screen
It is connected with the game's timing and scoring system, playing the player's game scores and related materials. From the perspective of the game, the time-scoring screen is more important. Some games can have no big screen, but they can't be used. The screen for timing scores. The key to the timekeeping score screen is to be accurate and clear on the spot, and to make it as vivid and powerful as possible (such as animation). The scoring screen mainly displays the player's game scores, materials, or other information in text or text plus graphic animation. Its color can be monochromatic, multi-colored, or full-color.
LED sports event screen design notes:
1. Security and reliability
The stadium crowd is dense, and the safety performance of its stadium equipment should be placed first. Under normal circumstances, the safety performance of the LED display of the stadium should meet the requirements of 5.4 of the SJ/T11141-2003 standard, and the reliability should meet the requirements of 5.10 of the standard. In terms of material selection, it is required to select polymer materials with good flame retardant properties (including LED module housing, LED module filling glue, PCB board, power cord sheath, etc.), and in the power supply design, the stadium LED display must be separate. Power supply and meet the requirements of 5.8 of SJ/T11141-2003 standard; cable line construction acceptance must meet the requirements of GB50168, GB50171; engineering quality should meet the requirements of GB50303. In addition, the LED display of sports events should have smoke, lightning protection, automatic fire alarm and automatic screen off function. The power distribution cabinet should have overload protection function, leakage protection function and step-by-step power-on function.
2. Installation location and quantity requirements.
The installation position of the LED display of sports events needs to ensure that more than 95% of the audience in the stadium has a fixed seat, and the viewing distance and wide vision are wide. At the same time, the display of the led display is required to enable the athletes, coaches and referees at the competition site (except for the referee on the spot in the diving competition) to be easily and clearly seen.
3. Maximum line of sight and character height requirements.
Outdoor sports events LED display brightness requirements 5000cd / square meter or more; dual primary color display 4000cd / square meter or more; monochrome 2000cd, square meters or more. Indoor stadium full-color LED display brightness requirements of 1000cd / square meter or more; dual-primary LED display 300cd / square meter or more; monochrome 120 cd / square meter or more. At the same time, in terms of character height requirements, the LED display screen of the swimming pool and diving hall with independent structure is at least 0.2m each character, and the LED display screen of the swimming and diving hall with integrated structure is at least 0.28m per character.
4. Optical performance requirements.
The sports display led display has a wide viewing angle, large visual distance, uniform brightness and adjustable. When the background illumination is less than 20lx, the contrast of the LED display should be 100e1. The white field chromaticity coordinates can be adjusted within the color temperature of 5000K-9500K according to the use environment. According to the CIE1931 chromaticity system, the tolerance is △x∣≦0.030. ∣ Δy ∣≦ 0.030.
5. Display content can be controlled in real time.
It is required to have a rolling time display of the game in real time; it can display the results of the rolling game; the page can be displayed to display the results of the game; the displayed text content can be switched automatically and manually. For full-color LED display with graphic and video display functions, text and pictures, animations, and live broadcast images should be automatically and manually switched between each other.
It is also worth noting that the display system of the stadium should be able to display the information of sports competitions in a clear, timely and accurate manner, and display the reality of the competition through multimedia technology, and create a strong and enthusiastic atmosphere for the competition. At the same time, the system is required to have a simple, clear, accurate and easy to operate man-machine interface, support a variety of sports competition projects, in line with the requirements of various sports competition rules, easy to maintain and upgrade.
