Whether in a bustling urban area or in a quiet suburb, we can see LED 디스플레이. However, there are significant differences in the installation environment between urban and suburban areas, which puts forward different requirements for the selection, installation, and subsequent maintenance of LED displays.
What are the specific differences? Just read the article, and you will know.
Difference 1: Difference between LED display product specifications and dot pitch
1). Urban installation environment
1.1). Crowd flow and 시거리:
As the core area of the city, the urban area has a huge flow of people and a constant stream of pedestrians and vehicles.
The viewing distance is relatively short because pedestrians are usually close to the display, perhaps within a few meters or tens of meters.
1.2). Clarity requirements:
Due to the short viewing distance, viewers have very high requirements for the clarity of the display screen.
Clear images can provide a better visual experience, attract more audience attention, and have higher value for commercial advertising, information broadcasting, etc.
1.3). Product specification selection:
In order to meet the requirements of high definition, LED display screens installed in urban areas mostly use small-pitch products.
The dot pitch (i.e., the distance between two adjacent pixels) is below P3, or even P0.6 or less, which means that the pixel density is higher and there are more pixels per unit area, thus achieving higher. The clarity is close to or reaches the display effect of the LCD splicing screen.
1.4). Other considerations:
In addition to clarity, LED displays installed in urban areas also need to consider anti-glare, anti-reflection, and other characteristics to ensure good visibility under various lighting conditions.
At the same time, due to the complex urban environment, the installation and maintenance of display screens also need to be more convenient and efficient.
2). Suburban installation environment
2.1). Crowd flow and viewing distance:
Compared with urban areas, suburbs have less pedestrian traffic, but vehicle traffic may still be large.
The viewing distance is long because the audience may be viewing the display in a moving vehicle or at a long distance.
2.2). Clarity and brightness requirements:
While clarity is still important, brightness and contrast become more critical factors when viewing at a distance.
The display needs to be bright enough to remain clearly visible in daylight or night lighting conditions while also having high contrast to ensure that the image is clearly distinct.
2.3). Product specification selection:
In order to meet the requirements of long-distance viewing and brightness, LED display screens installed in suburbs mostly use large-pitch products.
The dot pitch is between P4 and P20, and the specific choice depends on the display distance, budget, and the audience’s visual needs.
Large-pitch products usually have higher brightness, better heat dissipation performance, and lower cost. They are also more suitable for use in open areas such as suburbs.
2.4). Other considerations:
The suburban environment may be more severe, with weather conditions such as wind, sand, rain, and snow, so the display screen needs to have better protection performance.
At the same time, due to the relatively open space in the suburbs, the size and installation method of the display screen can also be more flexible and diverse.
Difference 2: Difference in LED display brightness requirements
1). Urban installation environment
1.1). Light pollution and installation location:
In the city, light pollution is really serious. There are neon lights and billboards everywhere, as bright as day.
However, LED display screens are mostly installed indoors in urban areas, such as in shopping malls, conference rooms, or on the exterior walls of buildings. In these places, there is not much direct sunlight, so the display does not need to be particularly bright.
1.2). 명도 requirement:
The brightness of LED display screens in urban areas does not need to be too high. Think about it: the indoor environment is dark, and if the display screen is too bright, your eyes won’t be able to bear it after looking at it for a while.
Moreover, a brightness that is too high wastes electricity and is not environmentally friendly. Therefore, the brightness of display screens in urban areas should be moderate, which makes people comfortable to watch and saves some electricity.
1.3). Energy efficiency also needs to be considered:
Nowadays, everyone pays attention to energy conservation and environmental protection, and LED display screens in urban areas are no exception. Moderate brightness is not only comfortable to watch but also saves energy and reduces operating costs. Isn’t this killing two birds with one stone?
2). Suburban installation environment
2.1). Open environment, direct sunlight:
In the suburbs, the environment is open, and LED displays are often directly exposed to the sun. Just imagine, in the middle of summer, the sun is so strong if the display screen is not bright enough, you can’t see clearly at all.
2.2). Brightness requirements must be high:
Therefore, the LED display screens in the suburbs must be very bright. This ensures a clear display even under strong sunlight. The display screen installed facing south is exposed to direct sunlight for a long time, and the brightness should be higher.
For north-facing rooms, where direct sunlight is less frequent, the brightness can be lowered appropriately. However, in general, the brightness of display screens in suburbs is much higher than that in urban areas.
2.3). Brightness adjustment, automatic:
The brightness of the LED display screen in the suburbs is adjusted automatically. Just think about it: the sunlight is strong during the day, so the display screen has to be adjusted to the brightest setting. At night, when the light is dim, the display screen also needs to be dimmed.
This can not only ensure the display effect but also reduce light pollution and energy consumption. How smart!
Specifically, the brightness range of outdoor LED displays in the suburbs is approximately between 1500nits and 8000nits.
If it is installed facing south and is exposed to direct sunlight for a long time, the brightness may need to be adjusted to above 3000cd/m², or even 7000cd/m² or higher. If it is installed facing north, the brightness can be lowered appropriately. Between 2000cd/m² and 5500cd/m² is enough. Of course, it depends on the ambient lighting conditions.
Difference 3: Difference in LED display installation methods
1). Urban installation environment
1.1). Limited space and complex environment:
In the city, every inch of land is valuable, and space is extremely limited. Moreover, the installation environment is also very complex, with tall buildings everywhere and wall structures of different kinds. Some are old houses, and the load-bearing capacity must be carefully considered.
In addition, there are dense crowds of people and vehicles in the city, so the installation must be done with caution so as not to affect the safety of traffic and pedestrians.
1.2). Consider load-bearing and protection:
When installing LED display screens in urban areas, special consideration must be given to the load-bearing capacity of the wall. After all, the display screen is not light, and it would be dangerous if the wall is not load-bearing enough.
In addition, protective measures must be taken, such as installing rain covers and lightning protection equipment, to ensure that the display screen can work normally even in bad weather.
2). Suburban installation environment
2.1). Open space and simple environment:
It’s different in the suburbs; the space is very open, and you can decorate it however you want. Moreover, the installation environment is relatively simple, without as many high-rise buildings and complex wall structures as in urban areas.
2.2). Consider stability and security:
When installing LED display screens in the suburbs, although the space is open, stability and safety must also be considered. After all, if the display screen is not mounted firmly, it will fall over if the wind blows, which will be a disaster.
Therefore, when installing, you must choose a good location, lay a good foundation, and ensure that the display screen is stable. At the same time, protective measures such as lightning protection and wind protection must be taken to ensure that the display screen is safe even in bad weather.
Difference 4: Differences in heat dissipation and protection requirements for LED displays
1). Urban installation environment
1.1). The environment is relatively closed; the temperature is high, but the heat dissipation conditions are good:
In urban areas, the environment is relatively closed, with tall buildings everywhere, and the air circulation is not so smooth, so the temperature is often higher. However, LED displays in urban areas are mostly installed indoors or on the surface of buildings, where the heat dissipation conditions are actually quite good.
There are air conditioners, fans, and other cooling equipment indoors, and the surface of the building can also dissipate heat through natural wind convection.
Therefore, the heat dissipation requirements of urban LED display screens are relatively low, and they can display normally at normal temperatures without worrying too much about overheating.
1.2). Low heat dissipation requirements, routine maintenance is sufficient:
Because of the good heat dissipation conditions, the heat dissipation design of urban LED display screens can be relatively simple without the need to install too many heat dissipation devices. Under regular maintenance, ensuring that the heat dissipation channel is unobstructed can ensure the normal operation of the display.
2). Suburban installation environment
2.1). The environment is open, with large temperature changes and high humidity:
It’s different in the suburbs; the environment is open and exposed to wind and sun. In summer, the temperature and humidity are extremely high, which is a test for LED displays.
High temperatures will cause the electronic components inside the display to heat up more, while humidity may cause the electronic components to get damp, cause short circuits, and cause other problems. Therefore, LED display screens in the suburbs must make great efforts to dissipate heat and protect it.
2.2). Air conditioning equipment needs to be installed to assist heat dissipation, and the protective performance must also be strong:
In order to ensure that the suburban LED display can operate normally even in harsh environments, it is often necessary to install air conditioning equipment to assist in heat dissipation.
The air conditioner can adjust the temperature inside the display screen and keep it within an appropriate range, thereby extending the service life of the display screen.
At the same time, the LED display screen in the suburbs also needs to be waterproof, windproof, and shockproof. Waterproof is to prevent rain from invading the interior of the display and causing damage.
Windproof is to prevent strong winds from blowing the display down or damaging it; and earthquake-proof is to prevent natural disasters such as earthquakes from affecting the display.
2.3). Comprehensive protection to ensure stable operation:
In general, LED display screens in the suburbs need to consider multiple factors in terms of heat dissipation and protection.
In addition to installing air-conditioning equipment, it may also be necessary to use special heat dissipation materials, design a reasonable heat dissipation structure, strengthen the fixation and support of the display screen, and other measures to ensure the stable operation of the display screen.
Difference 5: Differences between LED display content and functions
1). Urban installation environment
1.1). Large flow of people, diverse needs of viewers:
As the central area of the city, the urban area has a large flow of people, a complex crowd composition, and diverse needs of viewers.
Therefore, the display content and functions of urban LED displays need to be more extensive and diversified to meet the needs of different viewers.
1.2). Display content is rich and varied:
Urban LED display screens are not only used for advertising but are also widely used in big data displays, conferences, exhibitions, and other occasions. For example, in commercial districts, LED screens can play dynamic advertisements and promotional information to attract passers-by to stop.
In conference centers or exhibition halls, LED screens can display presentations, data analysis, video materials, and other content to enhance the quality of conferences and exhibitions. Efficiency and engagement.
1.3). Powerful and interactive:
Urban LED displays tend to have stronger functionality and interactivity. Some displays support touch interaction or interaction through other devices, which can be used for interactive games, information queries, etc.
This interactivity not only enhances the viewer’s sense of participation but also improves the attractiveness and practical value of the display.
2). Suburban installation environment
2.1). The flow of people is relatively small, and the needs of viewers are relatively simple:
In contrast, the flow of people in the suburbs is relatively small, and the composition of viewers is relatively homogeneous.
Therefore, the display content and functions of suburban LED displays are relatively simple, mainly focusing on advertising.
2.2). Mainly used for advertising:
Suburban LED screens are mostly used to play advertising videos, videos, text content, etc. These contents are designed to attract the attention of passers-by and increase awareness of the brand or product.
Due to the open space and long viewing distance in the suburbs, the advertising content needs to be more eye-catching and concise so that it can be clearly recognized at a longer distance.
2.3). The functions are relatively simple, focusing on practicality:
The functions of suburban LED displays are relatively simple, mainly playing advertisements. Although some display screens also have basic display functions, such as time display, weather forecast, etc., they generally focus more on practicality to meet the basic needs of suburban advertising.
결론
In summary, there are significant differences between urban and suburban LED displays in many aspects. These differences are not only reflected in product specifications and brightness requirements but also involve installation methods, heat dissipation, and protection requirements, as well as display content and functions.
Therefore, when selecting and installing LED display screens, we must fully consider the specific usage environment and requirements to ensure the rationality of the selection and the feasibility of the installation.
