Is the advertising screen at the door of your store always so hard that it is hard to see clearly? Last month I passed by the commercial street, and three of the five stores had scrolling screens that were either not bright enough or had bad points. It may be clueless to how novices can quickly increase their fans, but choosing the right outdoor advertising screen may directly determine the life and death of customer traffic - after all, no one wants their own promotional information to become a full screen mosaic, right?
First understand the basic parameters
That day, Lao Wang, who helped open a milk tea shop, selected the screen, and the merchant came up and quoted 6,800 per square meter. I asked "How much is the pixel spacing?" The other party stammered and said P10, but after installing it, I couldn't see the words clearly at all after I got five meters away. Here is the key point:
There is a living lesson: a chain supermarket is greedy for cheap and installed a screen without windproof structure. It was directly overturned on a typhoon day, and the maintenance fee is even more expensive than the screen. Now I understand why all stadium fence screens use aviation aluminum boxes?
The secrets of purchasing channels
You can buy both online and offline, but the routine is as deep as the sea. Last month, my cousin bought a "special screen" on an e-commerce platform. It was said to be outdoors, but it was short-circuited when it rained. Later, I took it apart and found that the waterproof adhesive strip was glued with double-sided adhesive! Here is a comparison for you:
| Key Items | Ordinary channels | Reliable channels |
|---|---|---|
| Brightness maintenance rate | Half a year attenuation 30% | Not exceeding 15% in three years |
| After-sales response | 3-5 working days | Arrive at the scene 24 hours a day |
| Installation instructions | Give an instruction manual | Professional engineer |
| Warranty scope | Panels only | Including control system |
Devil details to pay attention to when inspecting
Last week, I went to inspect an advertising screen for government projects. The manufacturer specially used a high-pressure water gun to rush it for half an hour during the demonstration. This IP68 protection level, military-grade sealant is used at the joints, and the corners are also designed with drainage grooves. To be honest, manufacturers who dare to test this way are worth considering.
The key point is here! Be sure to confirm before signing the contract:
FAQ Quick Questions Quick Answer
Q: Will the scrolling screen stutter?
A: Now mainstream control cards support 5G transmission, and 4K video broadcasts do not have buffering. Focus on whether there is any Frame synchronization technology , there will be no screen tear when the screen is linked together for dozens of screens.
Q: How to maintain it after installation?
A: Remember three key actions: ① Use an air gun to clean the dust every month ② Change the waterproof glue strip before the rainy season ③ Light it up for at least 2 hours a day (moisture-proof)
Q: Why is the price gap so big?
A: The secret is the box material! The magnesium alloy box is three times more expensive than the iron one, but it can be used for ten years without rust. There is a case: A seaside shop uses ordinary boxes, and it is corroded by salt spray in two years and is riddled with holes.
Finally, I would like to say that it is heart-wrenching: buying outdoor advertising screens is like buying insurance, don’t just look at the price in front of you. Find those who dare to provide Five-year full screen warranty , suppliers who can present third-party testing reports. I have seen some manufacturers with their own eyes that the test report date is earlier than the production date, so this is directly blocked! Next time you go to the inspection, remember to touch the back of the screen - the screw holes are well-made and even the screw holes are equipped with rubber pads. Only then will the details be revealed.
