Introduction
LED displays are becoming more and more popular. Whether in shopping malls, stages or cafes, they can be seen everywhere.
However, have you ever wondered why some displays look super cool while others are mediocre? If you want to buy a display, how should you choose?

1. Demand characteristics of LED displays in different application scenarios
1). Commercial advertising display
In the field of commercial advertising, LED displays are like “super big signs” for businesses to attract customers.
Imagine that on a sunny street outdoors, if the store sign is not bright enough, it will easily be drowned out by the surrounding environment.
Therefore, the LED display must have super high brightness, so that the advertising content can be clearly seen even under strong light and catch the attention of passers-by.
Moreover, the advertising images are usually carefully designed with bright colours and rich details. This requires the LED display to have high resolution and accurate colour reproduction capabilities.
If the picture is blurry or the colour deviation is too large, the effect of the advertisement will be greatly reduced.
Just like when we watch a movie, a clear picture with bright colours can make people’s eyes bright and attract people to stop and watch.
In addition, commercial advertisements often require a large display space. For example, on the facade of a large shopping mall or a billboard on a busy street, a small screen is definitely not enough.
This requires the LED display to have a strong splicing ability.
It can splice multiple screens together like a puzzle to form an oversized advertising display wall, making the advertising content more shocking and more eye-catching.
2). Stage background and performance
The stage performance scene is even more different. On the stage, the LED display is like a magical “background magician”.
It needs to be able to switch the screen quickly and smoothly and support dynamic video playback. For example, in a concert, the singer sings on the stage.
The background picture may need to quickly switch different scenes according to the rhythm and emotional changes of the song, from the romantic starry sky to the passionate flame, so that the audience can immerse themselves in the atmosphere of the performance.
Moreover, the design of the stage background usually needs to be customized according to the theme of the performance.
Different performances have different styles and themes and may require round, square or irregular screens or even bend or fold the screen into a specific shape.
This requires the shape, size and layout of the LED display to be flexible and changeable to meet the needs of various creative designs.
Most importantly, the stage performance environment is usually complex, and various equipment, such as lighting and sound, are running at the same time, which is easy to cause interference.
Moreover, during the performance, the screen may be used frequently, and even the audience may accidentally touch or touch it.
Therefore, the LED display must have good heat dissipation and anti-interference capabilities so that it can operate stably in a high-intensity performance environment without failure.
3). Live broadcast of sports events
Live broadcasts of sports events have even stricter requirements for LED displays. Imagine that in an exciting football or basketball game, the audience’s eyes are fixed on the screen, looking forward to seeing every wonderful moment.
This requires the LED display to synchronize the game screen in real-time without any delay or smear. If the picture is stuck or blurred, the audience will definitely be disappointed and may even miss some key moments.
Moreover, the audience of sports events usually sits far away, so the screen must be large enough, and the resolution must be high enough so that the audience can clearly see every detail of the game.
For example, the player’s expression, movement, and even the trajectory of the ball can be seen clearly.
In addition, many sports events are held outdoors, such as large stadiums or open-air athletic fields.
The environmental conditions in these places are relatively harsh, and they may encounter weather conditions such as wind, rain, and scorching sun.
Therefore, the LED display must have strong weather resistance and be able to withstand bad weather. At the same time, it must have a high level of protection to prevent dust, rain, etc., from damaging the screen.
4). Traffic information display
The role of the traffic information display is not small.
It is like an “information assistant” on the road, helping drivers and pedestrians understand road conditions and traffic information.
Therefore, it needs to display information clearly from different angles.
Imagine that if the driver looks from the side and the information on the screen is blurred, it may cause traffic congestion or accidents.
Moreover, the traffic information display usually needs to run uninterruptedly for a long time. Whether it is day or night, whether it is sunny or rainy, it must work stably.
This requires it to have high reliability and low maintenance costs. If the screen often fails or needs frequent repairs, it will not only affect the transmission of traffic information but also increase maintenance costs.
In addition, the traffic information display screen has some special functional requirements.
For example, it can be linked with the traffic signal system, and when the traffic light changes, the information on the screen can be updated in time.
It can also display real-time traffic conditions, telling drivers which road is congested and which road is unobstructed, helping them to better plan their routes.
5). Education and conference venues
In education and conference venues, the LED display screen is like a “multi-functional display stand”.
It needs to be used in an indoor environment so the brightness cannot be too high; otherwise, it will hurt the audience’s eyes. But it cannot be too dark. Otherwise, it will not be clear.
This requires moderate brightness, and it is best to have some eye protection functions, such as reducing blue light radiation to protect the audience’s eyes.
Moreover, the use of scenarios for education and conference venues is more diverse. Sometimes, you need to play PPT; sometimes, you need to play videos, and sometimes, you may need to display some pictures or text.
Therefore, the LED display screen must be able to support files in multiple formats to meet different teaching and conference needs.
Finally, the layout of classrooms and conference rooms varies greatly. Some may be rectangular, some may be square, some may have a podium, and some may not.
Therefore, LED display screens need to have flexible installation methods, such as wall-mounted, hoisted, or even placed on mobile brackets, so that they can be adjusted according to different spatial layouts.
In short, LED display screens are like a “jack of all trades” in different application scenarios, and they need to show different performances and functions according to different needs.
2. Key technical parameters for selecting LED display screens
Simply put, brightness is how “bright” the screen is. Its unit is called “nit”, and you can think of it as the brightness of the light. The higher the unit, the brighter the screen.
Measuring brightness is actually quite simple. Just use a special instrument (brightness meter) to measure the screen under standard conditions (such as without other strong light interference) to see how much light it can emit per square meter.
The requirements for brightness in different scenarios are very different.
For example, indoors, like our usual office, classroom or conference room, the brightness is about 300-800 nits. This brightness allows everyone to see clearly without irritating the eyes.
But if it is outdoors, especially in direct sunlight, the brightness must be much higher.
Generally speaking, the brightness of outdoor LED displays must reach more than 3000 nits. Otherwise, the words or pictures on the screen will be “covered” by the sun under the sun and cannot be seen clearly.
The resolution is how many “dots” (pixels) the screen can display. The more these dots, the clearer the picture. Its calculation method is related to the dot pitch and pixel density.
The dot pitch is the distance between two dots. The smaller the dot pitch, the higher the pixel density and the higher the resolution.
For example, a screen with a dot pitch of 2 mm will definitely have a higher pixel density than a screen with a dot pitch of 5 mm, and the picture will look more delicate.
The benefits of high resolution are obvious, the picture is clearer and the details are richer.
For example, if you watch high-definition movies or play games, a high-resolution screen can let you see more details and the picture is more realistic.
However, the higher the resolution, the better. It depends on how far you are watching the screen.
If you are far away, such as in a stadium or in front of an outdoor billboard, the human eye’s ability to distinguish details will be weakened, and you don’t need a particularly high resolution at this time.
But if you are watching it indoors at a close distance, such as in a meeting or class, a high-resolution screen is necessary.
The refresh rate is the number of times the screen can update the picture per second, measured in Hertz (Hz).
The higher the refresh rate, the smoother the picture will be, without flickering or smearing.
Imagine that you are watching a fast-moving picture, such as a car or a stage performance.
If the screen refresh rate is too low, the picture will be like “stuck”, flickering or smearing, which makes people feel uncomfortable.
A high refresh rate screen can solve this problem and make the picture look smoother.
Different scenes have different requirements for refresh rates.
For example, stage performances and live sports events, the pictures in these occasions change very quickly, and the movements of actors or athletes change instantly, so a high refresh rate screen is needed to capture every moment.
If the screen refresh rate is not enough, the audience will miss a lot of wonderful pictures.
The viewing angle is the range of the screen image you can see from different angles. It is divided into horizontal viewing angle and vertical viewing angle.
The horizontal viewing angle is from the left and right sides of the screen, and the vertical viewing angle is from the top and bottom.
Different scenes also have different requirements for viewing angles. For example, the traffic information display screen must allow drivers and pedestrians to see the information clearly from different angles.
If the viewing angle is too narrow, it will be troublesome if you look from the side, which may cause traffic problems.
The protection level is a standard for measuring the “resistance” of the screen, which is expressed by the IP level.
The IP level has two numbers, the first number is the dustproof level, and the second number is the waterproof level.
For example, IP65, the first number 6 means completely dustproof, and the second number 5 means it can prevent water jets.
The requirements for protection levels for indoor and outdoor screens are very different.
Indoor screens are more “delicate” because the indoor environment is relatively stable, with less dust and moisture, so the protection level requirements are lower.
But outdoor screens are different. They have to face wind and rain, sun and rain, so they need higher waterproof and dustproof levels.
For example, if the protection level of outdoor billboards or screens in stadiums is not enough, they are easily eroded by rain or blocked by dust, affecting the display effect and even damaging the equipment.
The service life of LED display screens is a matter of great concern to everyone. Its service life is affected by many factors, such as chip quality and heat dissipation design.
The chip quality is like the “heart” of the screen. A good quality chip can make the screen more stable and durable. Heat dissipation design is also very important.
The screen will heat up when it is running. If the heat dissipation is not good, the screen will easily have a “fever”, and the service life will be shortened.
The expected service life is closely related to the actual use environment.
If the use environment is not good, such as high temperature, dust or high humidity, even if the screen quality is good, the service life will be affected.
Therefore, it is important to choose a suitable screen.
For example, outdoors, you should choose a screen with high waterproof and dustproof levels and pay attention to regular dust cleaning and maintenance of the heat dissipation system so that the screen can be used longer.
In short, when choosing an LED display screen, these parameters are very important. According to your specific needs and usage scenarios, you can buy the most suitable screen by reasonably selecting parameters.
3. Brand and supplier selection of LED display screens
1). Importance of Brand
A brand is actually like a person’s “face”, which represents the quality, reputation and after-sales service of the product. Choosing a reliable brand is like buying yourself an “insurance” and making it easier to use.
For example, well-known brands have advantages in product quality control and technological innovation.
The product quality of these big brands is guaranteed, and the after-sales service is also in place.
For example, if there is a problem with the screen, they can respond in time and provide repairs and technical support so that users can worry less.
2). Evaluation criteria for suppliers
2.1). Production capacity
The production capacity of suppliers is very important, which includes production equipment, production technology and production capacity scale.
If the supplier’s equipment is advanced, the production technology is mature, and the production capacity is large enough, the quality of the screen produced is more guaranteed.
2.3). Quality control system
The quality control system is the key to measuring whether the supplier is reliable. A qualified supplier usually passes relevant quality certifications, such as ISO 9001.
These certifications are like the “graduation certificate” of the supplier, indicating that the quality of their products has been strictly tested.
2.4). After-sales service
After-sales service is the key to users’ peace of mind. Good suppliers will provide services such as warranty period, repair response time and technical support.
For example, BIBILED promises to provide corresponding warranty services to every customer, and provide timely and professional technical support and solutions, so that users can truly “buy with confidence”.
2.5). Price and cost performance
Price and cost performance are also factors that cannot be ignored when choosing a supplier. Under the premise of meeting quality and service, a reasonable price can allow users to buy more cost-effective products.
However, you can’t just look at the price but also comprehensively consider factors such as product performance, quality, and after-sales service so that you can buy a truly satisfactory screen.
In short, when choosing a brand and supplier of LED display screens, you must comprehensively consider factors such as brand reputation, production capacity, quality control, after-sales service and cost performance, so that you can buy products that are both reliable and cost-effective.
4. Installation and maintenance precautions
1). Preparation before installation
1.1). Site survey
Before installing the LED display, you must go to the site first. This is not a perfunctory look, but to carefully understand the various details of the installation environment.
For example, how much space is there at the installation location, whether the power supply conditions are met, whether the wall or floor is flat, etc.
This information is very important. If you don’t figure it out, you may encounter various troubles during installation.
For example, if the space at the installation location is too small and the size of the display you choose is too large, it will not fit in at that time.
Or if the power supply conditions do not meet the requirements, the screen may not be able to work properly. Therefore, the on-site survey must be done carefully.
1.2). Design plan
After understanding the on-site situation, the next step is to formulate an installation plan. This plan is not written casually, it should be determined according to the application scenario and installation environment.
For example, how to lay out the display screen, whether it is hung on the wall, placed on the ground or hung on the ceiling, must be planned in advance.
If you are installing an advertising screen in a shopping mall, you may need to consider the customer’s line of sight so that the position of the screen can attract the most attention.
If it is a stage background screen, the layout of the screen should be designed according to the shape of the stage and the needs of the performance.
In short, the design plan should be reasonable to ensure that the effect after installation meets the expectations.
2). Key points in the installation process
2.1). Strictly follow the instructions and specifications
When installing, be sure to follow the product instructions and installation specifications. These instructions and specifications are not for display.
They are summarized by the manufacturer based on years of experience. They can ensure that the screen is firm and stable after installation and will not loosen or fall.
For example, when installing the bracket, tighten the screws according to the requirements of the instructions and do not be sloppy. If the bracket is not firm, the screen may shake and even have safety hazards.
2.2). Power wiring
Power wiring is also very important. You can’t just pull a wire and be done. The power line should be planned reasonably to avoid voltage drop and electromagnetic interference.
If the power line is too long or the layout is unreasonable, it may cause the screen voltage to be unstable, affect the display effect, or even damage the screen.
For example, when installing a large outdoor display screen, the power line may need to go a long distance. At this time, you must choose a suitable cable to ensure that the voltage will not be reduced due to the long line.
At the same time, the power line should be far away from the signal line to avoid electromagnetic interference.
2.3). Signal transmission
The connection of the signal transmission line should not be sloppy. Make sure that the signal transmission line is connected correctly to avoid signal attenuation and interference.
If the signal line is poorly connected or interfered with, the picture on the screen may be blurred, flickering or colour deviation.
For example, when installing a high-definition video conferencing screen, the quality and connection method of the signal line directly affect the clarity of the picture.
Therefore, you must choose a high-quality signal line and connect it according to the specifications.
3). Daily maintenance and care
3.1). Clean the surface of the display screen regularly
After installation, daily maintenance is also very important. First of all, clean the surface of the display screen regularly.
Dust is the “natural enemy” of the display screen. If too much dust accumulates, it will affect the display effect and make the picture look blurry.
When cleaning, you can gently wipe the surface of the screen with a soft cloth to avoid scratching the screen. If it is an outdoor screen, there may be more dust, and the frequency of cleaning may need to be higher.
3.2). Check the cooling system
The cooling system is also critical. The display generates heat during operation. If the cooling system is not normal, the screen may overheat, affect its service life, or even malfunction.
Therefore, it is necessary to regularly check whether the cooling system is operating normally.
For example, check whether the cooling fan is rotating normally and whether the cooling holes are blocked by dust. If problems are found, they should be cleaned or repaired in time.
3.3). Check the power supply and signal lines
In addition to cleaning and heat dissipation, the power supply and signal lines should be checked regularly. These lines are the “lifeline” of the display. If there is a problem, the screen may not work properly.
When checking, pay attention to whether the line is loose, aged or damaged. If a problem is found, it should be repaired in time to avoid short circuits or signal interruptions.
3.4). Establish maintenance records
Finally, it is a good habit to establish maintenance records. By recording the time, content, and problems found during each maintenance, the operating status and maintenance history of the display can be better tracked.
In this way, if there is a problem in the future, the cause can be quickly found and solved in time.
Moreover, by analyzing the maintenance records, some rules can be summarized to prevent possible problems in advance so that the display can be used longer and more stably.
In short, when installing an LED display screen, the preliminary preparation work must be done well, the installation process must be standardized, and the maintenance after installation cannot be ignored.
Only in this way can the display screen be used smoothly and for a long time.
5. The Applications of the Pole LED Displays
In simple terms, the screen image will become more and more “high-definition” and the details will become more and more “delicate”.
Although the screens we use now are already very clear, they will be even more powerful in the future.
For example, the current Mini LED and Micro LED technologies can make the dot pitch of the screen (that is, the distance between the small dots on the screen) smaller and smaller, even reaching less than 1.0mm.
This means that the screen can display more delicate pictures, whether it is viewed from close or far away, it is super clear.
This high-resolution screen can not only be used as an advertising screen and stage background, but also in VR (virtual reality) and AR (augmented reality).
For example, when you put on VR glasses, the picture you see is like being in the scene, with super rich details.
Imagine that the screen can be bent, folded, or even rolled up like paper. This is flexible LED display technology.
This kind of screen will be very powerful in the future. For example, on the stage, the screen can bend with the shape of the stage to create all kinds of cool effects.
Or in outdoor advertising, the advertising screen can be folded up for easy transportation and installation, and then unfolded when needed, which is super convenient.
The future LED display will not just be a “display” but will become more “smart”. For example, through the Internet of Things technology, the screen can be remotely controlled and can automatically adjust the brightness and colour according to the environment.
In the field of transportation, the screen can automatically adjust the display content according to the traffic flow and remind the driver of the road conditions.
Moreover, the screen will “read” the needs of the audience. For example, through artificial intelligence, the screen can automatically adjust the display content according to the behaviour and preferences of the audience.
For example, when you are in a shopping mall, the screen will push the product information that you may be interested in according to your location and stay time.
Now everyone pays attention to environmental protection, and LED display is no exception.
In the future, screens will use more energy-efficient chips and driver circuits, consume less power, and use more environmentally friendly materials in the production process to reduce environmental pollution.
For example, some new packaging technologies can not only improve the reliability of the screen, but also reduce energy consumption. This is not only good for the earth, but also helps you save electricity bills.
In the future, LED displays will become more and more “slim” and easier to install.
Moreover, the screen will adopt a modular design, just like building blocks, which can be flexibly combined and disassembled according to needs.
For example, in large stadiums or exhibitions, modular LED displays can be quickly assembled and replaced, which is super convenient to use.
Moreover, this design can also reduce maintenance costs. If it breaks down, just replace the problematic module directly without replacing the entire screen.
In the future, LED displays can not only be used in advertising, stage and sports events but also expand to more fields.
For example, in schools, high-resolution LED screens can be used for interactive teaching, making the classroom more lively and interesting.
In hospitals, screens can be used to display surgical images or diagnostic results, allowing doctors to see more clearly.
Moreover, with the development of VR and AR technology, LED display screens will shine in these emerging fields.
For example, when you wear AR glasses, the screen can display virtual information in real-time, making your life smarter.
Although LED display screens are easy to use now, they are a bit expensive. However, in the future, as the technology matures and mass production begins, the cost will come down.
This means that more people can afford it. For example, in the mid- and low-end markets, Mini LED backlight technology will become more and more popular, and ordinary consumers can also enjoy the fun of high-definition screens.
6. Case analysis
1). Commercial advertising field case
1.1). Korean P2.5 curved curved LED flexible screen:
In Seoul, South Korea, a shopping mall uses a super cool P2.5 curved LED screen. This screen is like a huge cylinder with a circumference of 3.84 meters, a height of 7.2 meters, and an area of 27.648 square meters.
Its biggest highlight is that it can be bent and can fit according to the shape of the building, such as sticking it on the cylinder of the shopping mall, which looks very natural and not abrupt at all.
This screen has a very high pixel density, with 160,000 dots per square meter and a brightness of 700cd/m², so the advertising content looks particularly clear and bright.
Moreover, it can be bent 120 degrees, making it very flexible to install, and can handle any strange shape. In this way, the advertisement is not only beautiful, but also integrated with the surrounding buildings, becoming a unique landscape in the city.
2). Live sports event case
2.1). European Cup LED display
During the 2024 European Cup, Unilumin Technology installed super-large LED screens in several stadiums, with a total area of nearly 1,000 square meters.
The functions of these screens are not just as simple as displaying the game screen. They can also display scores and player data in real time, and even allow the audience to vote and play games, which is particularly interesting.
For example, the 460-square-meter LED screen at the Allianz Arena in Munich was particularly eye-catching during the opening game.
There is also the Veltins Arena in Gelsenkirchen, where the bucket screen is the largest in Europe, with an area of 280 square meters.
These screens allow the audience to clearly see every detail of the game no matter where they sit, and they can also participate in the interactive session.
The atmosphere in the scene is particularly warm, and the audience’s sense of participation is also very strong.
7. Conclusion
