Do you want to install a cool LED screen to do activities and promote promotions, but after searching, you will find that the online information is messy? What are the "manufacturer direct sales" and "ten-year warranty" that make people dazzled, and they are even more afraid of running away after receiving a deposit? Don’t panic. Today we will explore the tricks of finding LED advertising screen suppliers and teach you step by step to avoid the pitfalls that novices are most likely to step on.
1. Find out three things before finding a supplier
1. What exactly are you looking for?
Don’t ask “How much does it cost to make an LED screen” as soon as you open your mouth. It’s like going to a restaurant and just saying “I want to have a meal” – the boss can’t give you a quote at all. Think clearly first:
- Should I place it at the entrance of the mall or load a truck for a tour?
- How long does it take to open every day? Is it used on rainy days?
- Want to play videos or just play static posters?
For example, a milk tea shop owner wanted to put a new product advertisement at the door, but he bought an outdoor screen, which was so bright that it made the customer's eyes shook to tears at night. This is not clearIndoor 800-1200cd/m², outdoor 4000cd/m² upThe brightness standard joke.
2. Don't be fooled by "low price and all inclusive"
Some quotes on the market seem cheap, but when installed, "transportation fees" and "debugging fees" appear, and even the power cords have to be calculated separately. Remember these three pit prevention guides:
- Require suppliers to provideSub-item quote(Screen body, control system, installation and debugging clearly marked price)
- Confirm whether it containsThe warranty service starts from three years
- Ask clearlySecondary transport feeHow to calculate (especially high-rise shopping mall installation)
3. Seeing is the most important thing
Nowadays, many manufacturers make promotional pages more beautiful than the real thing. I suggest you:
- See at least 3 companiesStatus factory workshop (note whether there are core equipment such as SMT patch machines)
- Request a demoSame type of project cases (For example, if you want to make a curved screen, you will let others play a real-life video of the arc screen)
- Touch with your own handsSample box seam(If the gap exceeds 0.5mm, please choose carefully)
2. Experts are watching these hard indicators
"What is the concept of refresh rate 1920Hz?"
Let’s put it this way, the refresh rate of the screen of an ordinary mobile phone is only 60Hz, and the professional e-sports screen is 144Hz.1920Hz means that the tire texture will not be blurred when broadcasting racing advertisements, which is particularly important for live broadcast activities. But be aware that some manufacturers willDriver chip frequencyandActual refresh rateWork in a mixed manner, remember to ask for a third-party inspection report.
"Is IP65 protection preventing heavy rain?"
Last year, a newly installed LED screen in a shopping mall was short-circuited because it was used by the supplier.Glue filling waterproofImpersonating IP65. Real outdoor screens must be done:
- There is a seam at the boxSilicone sealing strip + drainage hole
- Power module is made separatelyGlue filling treatment
- Get itThird-party protection level certificate
"How come a promised life span of 10 years is broken in three years?"
There is an industry secret here - LED lamp beads have a lifespan of 50,000 hours, butDriver power supplyandControl SystemThere is the shortcoming. It is recommended to indicate special notes when signing the contract:
- Lamp beadsThe dead light rate within five years is ≤0.01%
- Power supply moduleThree years of replacement
- Control system softwareFree life upgrade
3. The major questions in installation and maintenance
Why does it take three days to install a screen?
Last month, a gym owner complained that he would have to install a 20-square-meter screen for a week. Later I found out that the supplier did not do itSteel structure pre-inspection, as a result, the load-bearing beam was unable to bear food and could not bear to work. Remember these key nodes:
- Measure before entering the siteWall flatness(The error exceeds 3mm and must be leveled)
- Steel structure needs to be madeWeight-bearing test(1.2 times the screen weight for 24 hours)
- Check before power onGrounding Resistor (It is safe to be less than 4Ω)
How to save the most money on daily maintenance?
Don’t believe the nonsense that makes you wipe the screen every week! It's the most reliable thing to do this in practice:
- Use every monthStatic brushesRemoving the ash once (don't use a wet rag)
- Check once a quarterPower connectorIs there any oxidation
- The rainy season starts earlyDehumidification mode(Many screens come with this function)
- Report the repair immediately if you find a tinted block (it will burn the driver IC if you delay it for a long time)
4. The soul torture that Xiaobai cares most
"Is it better to buy cheap online or find a manufacturer offline?"
A lesson from blood and tears tells you-Don't try to be cheap! Eight out of ten of the ten who claimed to be "direct sales by manufacturers" on Taobao are slander. Last year, a customer spent 80,000 yuan to buy a P3 screen, but it turned out that it was a refurbished module with less than half the nominal value. Remember:
- BringAutomated production lineOnly real manufacturers can control quality
- Only those with monthly production capacity exceeding 10,000 square metersScale cost advantage
- Export accounts for a high proportion usuallyQuality inspection is more stringent (For example, the acceptance standards for Japanese and Korean customers are 30% higher than those in China)
"Will customization demand be increased?"
It depends on whether you will make a request. If you want to save money, remember:
- When the arc screen is ≥150°No extra money(Many manufacturers support standard molds)
- To play 8K videos, you have to say it in advance (the ordinary receiving cassette cannot move)
- Choose as many special shape splicing as possibleGeneral box size (For example, 500x500mm is 20% cheaper than 600x338mm)
"How to judge whether after-sales service is reliable?"
I will teach you a ruthless trick - pretend to call at 2 a.m. and say that the screen is black and see how long it takes for the other party to answer the phone. All serious manufacturers24-hour technical response, some can also remotely diagnose faults. Pay attention to these two details:
- Is there anySpare parts library for more than five years(Especially, parts such as driver IC that are quickly discontinued)
- Whether the maintenance team is persistentLED display installation certificate(This certificate issued by the Ministry of Human Resources and Social Security)
When it comes to LED advertising screens, it is like finding a marriage partner - you can’t just look at your face (parameters), you have to find out your wealth (factory strength) and test your temper (after-sales service). Those established manufacturers that have launched projects in more than 110 countries often hide industry experiences that you don’t ask if you don’t ask. Next time I go to the supplier, remember to bring an expert friend and focus on theirs.Aging test lineandSpare Parts Stock Area, be sure to screen out a large number of fooling parties.
