Alas, are you all such confusions? Why do some advertising cars running all over the streets have dazzling screens and some pictures are battered? Today we will talk about how to choose this LED screen advertising car.

​Let me tell you a real case first​: Last year, a chain of catering brands held a promotion. The advertising car I rented was not bright enough during the day, and passers-by couldn't see the menu pictures clearly. As a result, the event was not only discounted, but also wasted three days of rent. You see, choosing the right equipment can really determine the success or failure of a business!

1. Why is the screen of a mobile advertising car so important?

To put it bluntly, the advertising car is a mobile signboard. Screen quality is directly related to:

• ​Can it attract attention?​: The outdoor ambient light is complicated, and the brightness is not enough, and it becomes "invisible advertising"
• ​​Is the picture clear?​: The resolution is low, and everything you see is mosaics ten meters away
• ​​Can't stand the tossing​: The road is bumpy every day, and if the quality is poor, it will be bad after two months of use.

A friend in the industry complained to me: "Some manufacturers are so full of fantasy, but the screen will be black after running twice on the highway, and the remediation rate can reach 30%!"

2. Choose the three hard indicators of mobile screens

1. ​​The brightness must be ruthless​​：
   It starts at least 4,000 nits outdoors and can be seen clearly in the sun. Now the industry benchmark can achieve 7500 nits, which is 15 times the brightness of an ordinary mobile phone screen! But be careful, the brighter the better, it must have intelligent adjustment function, save power and protect eyes.

2. ​​Don't fool the refresh rate​：
   The screen below 1920Hz is full of water ripples. Let’s put it this way, good advertising car screen shots and live broadcasts are not fake.

3. ​​The protection level cannot be saved​：
   IP65 is the basic threshold, it must be dust-proof and water-proof, and vibration-proof. The most exaggerated case I have ever seen is that a car leaked electricity on a rainy day and burned the control card. How dangerous would it be if it were in a downtown area?

3. Hidden skills that are easily overlooked

In addition to hardware parameters, these soft powers test the manufacturer's skills:

• ​​Quick disassembly and assembly design​: Every second of the event is to be fought for, and the professional box structure can form an advertising wall in 10 minutes
• ​Remote control system​: When encountering an emergency, the technical team can debug parameters online without having to wait for engineers to come to the door
• ​​Smart Power Saving Mode​: Automatically adjust the brightness according to the ambient light, and the savings are enough to travel to the business circle.

A guy who works on the ground pusher calculated the accounts with me: "Since I changed my car with an intelligent system, I have lost 1/3 of the monthly electricity bill. The money I saved in two years is enough to change a new screen!"

4. Service is the real thing

To be honest, no matter how good the equipment is, it will be a problem. The key depends on the manufacturer:

• ​​Is there a 24-hour response?​: The screen at the event in the middle of the night was black. Can you give a solution within 2 hours?
• ​​Is the technical team professional or not​​: Installation and debugging is not simply hanging up the screen, but you have to consider the details of vehicle counterweight and power load.
• ​​Is the spare parts reserve enough?​: I heard that some agents have to wait for imported accessories for repairs, and it takes half a month to wait.

The mobile stage car used in a music festival last year was in a dark screen when it was flooded on rainy days. Fortunately, the manufacturer's technician brought spare parts to repair it on site, so he did not delay the finale performance. At this critical moment, service ability is more important than anything else.

5. The price must be calculated clearly

Don’t just look at the equipment quotation, focus on these hidden costs:

1. ​Maintenance cost​: It may take thousands of driver ICs to replace them outside the warranty period
2. ​​Depreciation speed​: The residual value of a poor quality car in two years is only 30%
3. ​Opportunity Cost​: The business opportunity delayed by equipment failure is much more expensive than repair costs

For example, although a certain brand is 15% expensive, it saves 40,000 maintenance fees within the five-year warranty period. No matter how you calculate this account, it is worth it, right?

​​Personal opinion time​: I think choosing a mobile advertising car is like finding a partner. Just looking at the appearance (screen effect) is not enough, but also depends on the family’s financial situation (technical strength) and sense of responsibility (after-sales service). Now some manufacturers are engaged in price wars, making the industry messy. But a company that is truly attentive will always work hard in places you can't see - for example, the low-bright and high-gray technology can enable the screen to maintain a clear-level picture on cloudy days. This is the real ability.

After all, advertising cars are tools to help you make money. Taking the time to choose the right partner is much more important than saving thousands of dollars. Next time I see an advertising car running all over the street, why not take a closer look at the screen details - maybe you can see the trick?
