Alas, do you often see those cool LED large screens on the street? The advertising screen is played in a scrolling manner like running water, and it can shine and illuminate the entire street at night. I must have thought in my mind: "Where to buy this thing? How much does it cost to install one? "Don't worry, today we will break it and talk about this.
1. First understand: What kind of scenes require an outdoor scrolling screen?
To put it bluntly, the outdoor scrolling screen is a "all-weather billboard". If you open a shopping mall, start a real estate, set up a chain store, or hold an open-air event, this thing is much more exciting than posting posters. To give a real example: Last year, a 200-square-meter scrolling screen was installed in a business district in Shenzhen, and the traffic volume increased by 30% - this is a real money!
But you have to pay attention, this is not something you can use by simply buying a screen. The outdoor environment is much more ruthless than the indoor environment:
- Wind and rain: You have to withstand typhoon days
- Exposed sun: You can see clearly at noon
- Day and night temperature difference: It must be used normally from minus to 40 degrees.
2. Hard core parameters: You must keep an eye on these points before buying
When I first entered the industry, I had a headache when I saw the parameter table. Now let’s focus on you and remember these three core indicators:
1. The brightness must be ruthless
The outdoor screen starts at least 4,000 nits, and high-end products can reach 7,500 nits. Let me put it this way, how bright the mobile phone screen is only? 500 nits are the best! Don’t believe in those false label parameters, it’s the most realistic way to get the test report.
2. Don’t get too much refresh rate
It is not possible to start at 1920Hz, especially when shooting videos. You must have seen water ripples appear on the LED screen when you take a mobile phone? That is, the refresh rate is not bad enough.
3. The protection level must be tough
IP65 is the basic threshold, what does this certification represent? Dust-proof, waterproof and waveproof! When it rains heavily, you stand in front of the screen and hold an umbrella, it is more resistant to making things than you.
3. Purchase channel: Which one is reliable online and offline?
Let me tell you the truth first: This line of water is very deep! I have seen too many people suffer great losses by greed for cheap things. There are only three reliable channels:
-
Directly operated by the manufacturer
Just find brands with your own factory. Let me tell you an industry secret: many OEMs are second-hand dealers, and they will push them around if there is any problem. We must be sure that there are ISO9001 and CE certifications. For example, there is a factory in Shenzhen that produces tens of thousands of square meters per month, and 87% of the goods exported to Japan and South Korea account for 87%. This is safe.
-
Engineering business cooperation
If the usage is large (for example, starting with 10 screens), please contact a local engineer to pack it. They can handle the installation approval in one-stop, but they have to guard against middlemen to increase the price.
-
Online official store
Nowadays, big factories have Tmall and JD stores, but pay attention! Don't buy standard products, outdoor screens must be customized. Online prices are mainly about comparing prices and looking at parameters. If you really want to place an order, you have to ask technicians to come to measure the size.
4. Avoiding Pits: The 5 most easiest thunders to beginners
-
Only look at the price and not after-sales service
There was a restaurant owner who had a cheap picture, but the screen was broken and couldn't find anyone to repair it. Finally, the whole thing was disassembled and reinstalled, which cost three times the amount!
-
Ignore the installation environment
A customer did not do anti-salt spray treatment in a coastal city, and the screen rusted in half a year. Remember to customize the seaside cities!
-
Trouble update content
Nowadays, the mobile phone APP control is popular, so don’t buy the old antique that needs to be updated with USB flash drives.
-
The power package didn't keep up
Before installing the screen, you must first confirm the circuit load. A gym burned the transformer due to insufficient power.
-
No approval procedures were completed
Especially the large screen on the main road, you can dismantle and reinstall it in minutes without an urban management approval.
5. Tell me some personal experience
After working for so many years, I just want to say something to a novice:Don't be greedy for cheap, look at long-term costs. Outdoor screens are long-term trading, and the maintenance fee can be several times different. There is a chain supermarket chain that buys defective products at a cheap price. After three batches of screens changed, it was 20% more expensive than buying high-end products directly.
There is also a cold knowledge: now many manufacturers are playing "renting instead of purchasing", especially those who hold activities. For example, if you want to hold a beer festival, renting for two weeks is much more cost-effective than buying, and you can also upgrade the latest models for free. However, you have to book three months in advance, and there is no order for peak season.
6. Real case: How to choose a reliable supplier?
Last year, a friend wanted to install a large screen on the exterior facade of the mall and went to more than a dozen suppliers. Finally, I have a chance to lock in a person with experience in Tokyo Stadium in Japan. The key points are to be taken into consideration:
- 24-hour technical response (I still have problems in the middle of the night)
- Provide a three-year warranty (the industry generally only has two years of insurance)
- Can produce anti-glare solutions (not affecting the opposite office building)
As a result, it took me half a year and experienced two typhoons and nothing happened. The most amazing thing is that they came to inspect the after-sales service with a thermal imager and discovered a hidden danger in advance - this service is really nothing to say.
After all, buying an outdoor scrolling screen is like finding a partner. You can't just look at the appearance, but you have to look at the inner quality and service guarantee. Next time you see a large LED screen on the street, do you already have the confidence to know how to choose? Remember, a good screen can last for seven or eight years, the key is to find the right manufacturer!
