From October 18th to 27th, 2019, the 7th World Military Games is about to kick off. This is also the first large-scale comprehensive sports event held in China. In this military games, more than 300 events and 35 stadiums were held. Among the 35 stadiums, there are indoor and outdoor stadiums. LED display screens go hand in hand with stadiums. With the arrival of this big wave of stadium construction, LED display screens are bound to be promising. So for similar stadiums, how to choose a suitable full-color LED display?
1. Screen type
The specific application needs to be considered. For example, indoors, in addition to LED small pitch screens, indoor stadiums (basketball stadiums, etc.) often have adjustable bucket screens, and several small bucket screens (which can be moved vertically) shrink to a large bucket screen. It can adapt to all kinds of occasions in the live broadcast of matches (basketball stadium, etc.).
Second, the protective performance of the screen
For indoor or outdoor gymnasiums, heat dissipation has always been a part of the criticism of sports screens. Especially for outdoor screens in a changeable climate, high flame retardant grade and protection grade are necessary. Generally speaking, IP65 protection grade and wire V0 flame retardant grade are more ideal choices, and it is better to have a built-in cooling fan.
Especially for outdoor sports events, it is necessary to take into account our country's special and changeable climate environment. For example, the southern coast focuses on anti-tide, high-altitude areas are resistant to cold, and desert areas need to consider heat dissipation. Such areas must use high-level screens.
3. Overall brightness contrast and energy efficiency
The brightness requirements of outdoor sports display screens are higher than that of indoors, but it is not that the larger the brightness value, the more appropriate. For LED screens, brightness, contrast, and energy-saving effects need to be considered comprehensively. Choosing an LED display product with a high-energy-efficiency design can guarantee safety, stability and service life.
Fourth, the choice of installation method
The installation location determines the installation method of the LED display. When installing screens in stadiums, it is necessary to consider whether the screen needs to be grounded, wall mounted or embedded in the wall, whether it supports front and rear maintenance, and the ease of installation and maintenance.
Five, viewing distance
As a large outdoor stadium, users who watch at medium and long distances often need to be considered. Generally, display screens with a larger dot pitch are selected. P6 and P8 are two common dot pitches in outdoor stadiums. . For indoor viewers, the viewing density is higher and the viewing distance is closer, so P4 and P5 are more appropriate for the dot pitch.
6. Whether the viewing angle is wide
For spectators in stadiums, due to the different seating positions, the same screen, the viewing angle of each spectator is more dispersed, the use of wide-view LED screens can ensure that each spectator has a good viewing experience.
Seven, high refresh rate
The use of a high refresh rate display screen can ensure the smoothness and continuity of the live broadcast of large-scale sports events, and the human eye’s perception is more comfortable and natural.
In summary, these issues need to be paid attention to if the stadium wants to choose a good LED display. At the same time, when choosing, it is necessary to focus on whether the manufacturer has prepared a series of appropriate solutions for the broadcast of sports events.
