Alas, I said, bosses, do you also have such confusion? I wanted to install an outdoor large screen for promotion, but after checking it online - good guy! There are many manufacturers that cost thousands to millions, and there are so many manufacturers that can rank in France. Who should I buy it? Today we broke it apart and broke it up and talk about this big problem.
1. Three truths you must know before buying an outdoor LED screen
1. Price ≠ quality, but cheapness is definitely a trick
For example, it is also a P10-specification screen (that is, the pixel pitch is 10 mm), some offer 8,000 yuan per square meter, while others dare to call 30,000 yuan. The trick here is:
• Light bead quality: Imported chip life span 50,000 hours vs miscellaneous brands 20,000 hours
• Protection level: Real IP65 waterproof (not damaged by heavy rain) vs virtual waterproof (the screen will be lost when the rain is in the end)
• Power system: Military-grade power supply is stable and operated vs. Copyright power supply is tripped twice in three days
2. The installation location determines the product parameters
Don't rush to ask "what brand is better", understand these first:
• The screen faces south and north? (Direct sunlight should be direct to choose a high-bright screen above 7000cd/m²)
• Is there a glass curtain wall around it? (Anti-reflection treatment can save 30% of operation and maintenance costs)
• Average daily playback time? (Screen with intelligent cooling system can be used for 3-5 years)
3. After-sales service is more important than sales commitment
There is a tacit secret in the industry: many manufacturers pretend to die after selling the screen. I have seen a large screen failure in a shopping mall. I waited for half a month before someone came to repair it, and directly lost millions of passenger flow. So, please ask clearly before signing the contract:
✓ Is there a 24-hour technical response? (It can save lives at critical moments)
✓ Are there any local service outlets? (Inter-provincial maintenance can drag you to death)
✓ How to charge outside the warranty period? (Don't be cheated by the sky-high maintenance fees)
2. How important is it to choose the right manufacturer? Look at these three hard indicators
Some people may ask: The manufacturer's publicity is so varied, how can we judge whether it is reliable? Teach you three tricks to verify the authenticity:
The first thing is to look at the production strength
A truly confident manufacturer dares to show its assets:
• Is the workshop large enough? (Only those with a monthly output of more than 10,000 square meters can accept large orders)
• Is there a fully automatic patch machine? (The manual welding screen will definitely cause problems if it takes half a year)
• Is the quality inspection process perfect? (There are 8 inspections required from raw materials to finished products)
Here is a real case: the fenced screen used in the Tokyo Olympic venue last year was built by the manufacturer in Shenzhen, from chip packaging to full screen assembly in one-stop, which has withstood the high-intensity use for 18 consecutive days.
Second, look at technical patents
A layman watches the excitement, while an expert sees the trick. Focus on these core technologies:
• Low bright high gray technology(You can see clearly at noon, not dazzling in the middle of the night)
• Intelligent brightness adjustment(Save up to 40% of electricity, and the electricity bill will bloom)
• Quick disassembly and assemble structure(Replace the picture like building blocks, saving sky-high lifting fees)
The third thing is to look at practical cases
Don’t just listen to sales bragging, just ask for a list of projects:
→ Have you ever done a super-large project with a value of more than 500 square meters?
→ Are there any successful cases in high-temperature and high-humidity areas (such as Southeast Asia)?
→ What places have you worked with that require 7×24 hours of operation? (Subway stations, gymnasiums, etc.)
3. Where can I find a reliable supplier? Three golden channels
1. Face to face the industry exhibition
Every year at Shenzhen Guangbo Exhibition and Shanghai Advertising Exhibition, leading manufacturers will bring the latest products to the exhibition. Last year, a chain restaurant owner touched more than 20 samples at the exhibition, and finally chose a house that was very good for heat dissipation. In his words, "It feels warm to the touch, and it is much more at ease than hot ones."
2. Factory inspection on cross-border e-commerce platform
Nowadays, Ali International Station and Manufacturing in China, manufacturers with a slightly more formality will be released:
✓ Real-life videos in the workshop
✓ Original test report
✓ Overseas installation cases
Focus on those who show CE and CCC certifications, which are not fake at will.
3. Recommended by local service providers
There is a trick: find the advertising engineering company in your city. They deal with manufacturers all year round, and which box is not easily deformed after-sales service. But be careful when taking kickbacks, it is best to ask a few more comparisons.
4. What to do if you encounter problems? I've stepped on these thunders for you
Situation 1: Color blocks appear as soon as they are installed
→ Eighty-mostly it was bumped during transportation, please contact the manufacturer immediately to change the module
→ Focus on checking whether the packaging has anti-collision angle (double-layer pearl cotton is standard)
Situation 2: Water ripples appear after rainy days
→ Either the waterproof glue is not well-made or the box joints are deformed
→ Comprehensive airtightness testing should be performed before the rainy season (professional manufacturers provide this service)
Situation 3: Always feel the screen shaking during playback
→ The refresh rate is not enough! Outdoor screen must be at least 1920Hz or above
→ Let the manufacturer pick up the computer to broadcast the fast motion screen test on site
Personal experience talk
I have been working in advertising projects for more than ten years and have seen too many people suffer great losses by greed for cheap things. To be honest: choosing an LED screen is like finding a marriage partner. It’s not enough to just look at the appearance (display effect), but also depends on family background (manufacturer strength) and temper (after-sales service).
Recently, I found a treasure manufacturer when I was helping chain supermarkets to select screens. They made screens exported to Japan and even passed earthquake resistance tests - do you know how frequent earthquakes in Japan are? This kind of product that has been tested by harsh environment is to be down-to-earth. What's even more amazing is their operation and maintenance system. Which module on the screen is about to expire, and it will be reminded to replace it three months in advance. This service is really in my heart.
Finally, I would like to give you a sixteen-character mantra: look at the actual examples more carefully, check the qualifications carefully, review the contract strictly, and focus on after-sales service. Remember, what you bought is not a screen, but a stable customer flow in the next 5-10 years!
