介绍
The trailer LED display is a type of 移动卡车LED显示屏. Unlike the truck LED display, it is not installed on the bus body but stands on the trailer. So, what should you do if you want to buy an LED trailer display? How to choose? This article will tell you.
1. Clarify the purpose of the trailer LED display
First, you have to think about the purpose of buying a trailer LED display, which is related to whether you really need to use it, or how large the trailer LED display you want to buy is.
We all know that trailer LED displays are LED displays that can be moved at any time. If you want a fixed display that will not be easily moved if installed in one place, then a rental LED display or a fixed LED display will be more suitable.
If you want an LED display that can be moved at any time, then a trailer LED display is very suitable.
Of course, there are many application scenarios for trailer LED displays, such as:
- Outdoor music festival:
Imagine that at a sunny outdoor music festival, the crowd dances on the grass to the rhythm of the music, and at this time, a trailer LED display slowly drives into the scene.
It is like a mobile information center, not only updating the performance schedule in real-time but also playing the sponsor’s advertisements so that people can catch the latest information while enjoying the music. Such a scene is both practical and fun.
- 大的 展览:
In the exhibition, the trailer LED display has transformed itself into an important tool for displaying exhibit information and corporate culture.
Its high 解决 and bright colors can attract the audience’s attention and let them have an intuitive understanding of the exhibits in a short time. For exhibitors, this is undoubtedly a good helper in enhancing the brand image and attracting potential customers.
- Large-scale speeches:
The trailer LED display can be easily installed on the vehicle to achieve “talking while walking” so that candidates can flexibly choose the speech location, widely cover voters, and increase interaction opportunities.
The LED display screen displays the content of the speech with high 亮度 and clarity, including text, pictures, and videos, making the speech more vivid and intuitive, making it easy to attract and keep the audience’s attention.
Through wireless or wired connections, candidates can instantly adjust the content on the display, such as PPT, video, etc., and flexibly respond according to the on-site response to enhance the pertinence and interactivity of the speech. Just like the candidate speeches in this US election, the trailer LED display screen also contributed.
- Other scenarios:
Of course, the use of trailer LED displays is far more than that. In commercial publicity, it is like a mobile billboard, whether in 购物广场, squares or streets and alleys, it can attract the attention of passers-by and bring rolling traffic to merchants.
在 运动的 events, it can update game information in real time, allowing the audience to keep abreast of the dynamics of the game and enjoy a more immersive viewing experience.
2. Choose the right trailer LED display model
You have to think about how far your audience will watch the display. If the distance is far, such as at a large outdoor music festival, then the resolution and pixel pitch can be slightly looser; after all, the audience at a distance can’t see details that are too clearly small.
However, for indoor exhibitions or close-up displays, you have to choose a display with high resolution and small pixel pitch so that the image looks more delicate and realistic. For example, for large outdoor music festivals, the audience may be far away from the display, so you can choose a display with a slightly larger pixel pitch but higher brightness.
For indoor exhibitions or close-up viewing, you need to choose a display with a smaller pixel pitch and higher resolution.
- Display size and weight:
When it comes to size and weight, it depends on how strong your trailer is. If the LED display is too large and heavy, the trailer may not be able to pull it, or it may sway on the road, which is not good.
Therefore, when choosing a display screen, you must first understand the carrying capacity of your trailer and then choose a display screen of the right size to ensure a safe journey.
In addition, you also need to consider the convenience of the display screen during transportation and installation and whether additional support structures are needed to maintain its stability.
- 高亮度：
Brightness is also a big problem. Imagine that if your display screen is not bright enough in the sunny outdoors, the audience will have to squint their eyes and stretch their necks to see the content on it clearly.
Therefore, it is necessary to choose a high-brightness LED display screen that can ensure that the image can be clearly seen even under strong light.
- 宽的 可视角度:
The viewing angle cannot be ignored. After all, your audience may come from all directions. If the viewing angle of the display screen is not wide enough, some viewers may have to tilt their heads and turn their bodies sideways to see clearly.
Therefore, choosing a display screen with a wide viewing angle can allow more viewers to have a good viewing experience in different positions.
- 防护等级：
Finally, we have to talk about the protection level. After all, trailer LED displays are often used outdoors or in complex environments. If the waterproof and dustproof performance is not good, it is easy to malfunction.
Therefore, when choosing a display, you must look at its protection level to ensure that it can withstand the test of various environments.
Common protection levels include IP65, IP67, etc., among which IP65 means that the display is dustproof and waterproof, while IP67 means that the display is dustproof and has short-term immersion in water. When choosing a display, you can choose the corresponding protection level according to the needs of the actual use scenario.
3. How do you choose the head of the trailer LED display?
The choice of the head of the trailer LED display is a key decision because it is not only related to the transportation and installation efficiency of the display but also directly affects the display effect and safety of the display. Here are some suggestions:
1). Consider transportation requirements
- Size and weight:
First, make sure that the size and weight carrying capacity of the selected head can meet the transportation requirements of the trailer LED display.
The size and weight of the display may vary depending on the model and specifications. Therefore, when choosing the head, you must understand the specific size and weight of the display and choose a head that matches it.
- Traction:
The front of the vehicle needs to have enough traction to drag the heavy display. If the traction is insufficient, it may cause problems during transportation or even damage the display. Therefore, when choosing a front, pay attention to whether its traction is strong enough.
2). Consider the display effect
- Appearance design:
The appearance design of the front of the vehicle should be coordinated with the style and theme of the display to enhance the overall display effect.
For example, if the display is used for an outdoor music festival, a stylish and dynamic front design can be selected; if it is used for an indoor exhibition, a more concise and generous design can be selected.
- Lighting system:
The lighting system equipped on the front of the vehicle is also important, especially at night or in a dimly lit environment. A good lighting system can ensure that the front part of the vehicle is clearly visible, improve safety, and also add a touch of brilliance to the display.
3). Consider safety
- Braking system:
The braking system of the front of the vehicle must be reliable to ensure that it can stop quickly in an emergency. Choosing a front of the vehicle with advanced braking technology and good braking performance can greatly reduce the safety risks during transportation.
- 稳定：
During transportation, the stability of the front of the vehicle is crucial to the safety of the display. Choosing a head with a stable suspension system and good handling performance can ensure that the display screen remains stable during transportation and avoid damage caused by bumps and vibrations.
- Safety devices:
The head should also be equipped with necessary safety devices, such as reversing radar, blind spot monitoring, etc., to improve safety during driving.
4). Consider economy
- Fuel efficiency:
Choosing a head with high fuel efficiency can reduce transportation costs, which is especially important for users who need to transport display screens for a long time.
Maintenance cost: The maintenance cost of the head is also one of the factors that need to be considered. Choosing a head that is easy to maintain and maintain can reduce the subsequent maintenance costs.
4. Understand the power supply and compatibility of trailer LED display screens
There are 3 types of power sources for trailers. Let’s take a closer look:
1). Self-contained power supply on the vehicle
For some trailer LED display screens, they may be equipped with their own power supply system. However, this can only be used for trailer LED display screens with a smaller screen area, and large areas are not allowed.
This power supply system usually includes a generator or other power supply equipment that can provide the required power for the display screen. For example, some small trailer LED screens may use a 10 kW generator to meet power supply needs. The voltage generated by these generators is usually 100V to 220V, which can directly power the screen.
2). External 电源
Most trailer LED screens, especially those with large screen areas and high brightness, may require an external power supply to work properly.
The external power supply usually comes from the power system at the event site, and the screen can be connected to the power socket through a cable. This power supply method ensures that the screen has sufficient power support to achieve the best display effect.
3). Solar power supply
Because the trailer LED screen is movable, sometimes the power supply cannot be charged in time. So, a solar panel is installed on the trailer LED screen to power the screen. However, this method is also only suitable for trailer LED screens with a relatively small overall screen area.
结论
When choosing a trailer LED screen, every detail is crucial. From the durability of the screen to the energy efficiency, from the convenience of maintenance to the rationality of the budget, each factor affects the long-term performance of the screen and your return on investment.
