Does anyone know how to choose LED display in stadiums?

In general, the safety performance of the LED display screen of the stadium should meet the requirements of the SJ T11141-2003 standard, and the reliability should meet the requirements of the standard. In terms of material selection, it is required to choose polymer materials with good flame retardant performance (including LED module shell, LED module filler, PCB board, power cord sheath, etc.), and at the same time, in terms of power supply design, the LED display screen of the stadium must be supplied separately and meet the requirements of SJ T11141-2003 standard; The construction acceptance of the cable line shall meet the requirements of GB50168 and GB50171; The quality of the project should meet the requirements of GB50303. In addition, the LED display screen of sports events should have smoke detector, lightning protection, automatic fire alarm and automatic screen shutdown functions, and the power distribution cabinet should have overload protection function, leakage protection function and step-by-step power-on function.

The installation location and quantity of the display screen require that the installation position of the LED display screen for sports events needs to ensure that more than 95% of the spectators with fixed seats in the stadium can be effective, with a wide visual distance and vision. At the same time, it is required that the LED display display content can be easily and clearly seen by the athletes, coaches and referees at the competition site (except for the on-site scoring referees in diving competitions). The maximum sight distance and character height of the LED display are required for outdoor stadiums, and the brightness of the full-color LED display is required to be more than 5000cd square meters; Dual-color display screen of more than 4000cd square meters; Monochrome 2000cd, square meters or more.

The brightness of the full-color LED display screen of indoor stadiums is required to be more than 1000cd square meters; Dual primary color LED display 300cd square meters or more; Monochrome 120cd square meters or more. At the same time, in terms of character height requirements, each character of the LED display screen of the swimming pool and diving hall with independent building structure is at least higher, and each character of the LED display screen of the swimming and diving hall with integrated building structure is at least higher. <>

The LED display around the football field is the fence screen, which is mainly used for commercial advertising and can also play back the wonderful shots on the field. The LED fence screen is made up of a plurality of box screens, the weight and connection of each box are precisely designed to ensure the speed of disassembly and assembly, and a soft mask will be installed on the general box, which can effectively avoid injuries caused by players falling. LED Display:

Large full-color LED screen. It is more common in the NBA arena, and is used for the best game pictures at the game site, and the slow-motion replay is replayed, so that the audience does not miss any wonderful pictures. Timing scoring LED display competition is generally determined by the score, timing scoring LED display carries the heavy responsibility of calculating the score of the game, it is connected with the timing scoring system of the game, the player's results and related information.

Red, green, and blue contribute differently to the color of white. The root cause is due to the fact that the retina of the human eye perceives light differently at different wavelengths. After a large number of practical tests, the following ratios are obtained for reference:

The simple red-green-blue brightness ratio is: 3:6:

1. The accurate red-green-blue brightness ratio is::: The space is small, the best viewing distance is near, in order to achieve a certain display effect, the point spacing must be reduced, and vice versa. In addition, if it is an outdoor screen, you should also pay attention to the heat dissipation of the screen.

If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, so that the display system can not work normally, so ventilation and cooling equipment must be installed. <>

Shenzhen Jiadi Technology **** Stadium LED Display Specifications Stadium LED Display Specifications With the improvement of LED display products in technology and performance, the advantages of the shocking picture are fully displayed, whether it is the application effect or installation and maintenance, the current mainstream large-screen display products can meet the needs of users, and at the same time show extraordinary effects. LED display has emerged in the fields of large-scale exhibitions, stage effects, and high-end displays, and has become more and more widely practical. Today, Fengliyuan Optoelectronics will introduce how the model of the LED display is divided.

Outdoor led display features and specifications:

1. Features: large luminous point, large pixel spacing, high brightness, can work in the sun, with windproof, rainproof, waterproof function, suitable for long-distance **, mostly used in bustling street intersections, **dense places such as shopping malls, office building walls, football stadiums and other environments. The life span is more than 100,000 hours.

2. Specifications: The size of the single module is 32*16cm, composed of 512 straw hat lamp beads with a diameter of 10mm, the point resolution is 10000 m2, the screen brightness (average) is 6500cd m2, and the viewing angle is 120° horizontally, 10° vertically up and 30° down

Outdoor is generally a bright P10 (LED is 10mm) or P16 (LED is 16mm) unit board composed of monochrome or two-color and full-color display, these two LEDs are relatively large, so the display is also relatively large, suitable for large screens.

Is it a display on the sidelines of the arena?
