Walking on the streets of Qingxi Town, you must be overwhelmed by those colorful LED screens, right? I wanted to install a cool advertising screen for my store, but I found that I couldn’t find a reliable supplier at all. The map found that it was all hardware stores, and the people I asked about acquaintances recommended were all second-deao dealers. Don’t worry, today we will lift this mystery and teach you step by step to dig out a real LED screen expert in Qingxi.
Three life gates to finding a company
Let me first talk about an abnormal phenomenon: truly professional LED screen companies are often hidden deep in industrial parks, rather than shops on the street. Last year, a restaurant owner found a street shop to find a small street shop, but the installed screen flashed with snow every rainy day. Finally, he found that he was using a second-hand refurbished module. Remember these three key coordinates:
- Depend on the factory size: Only enterprises with a monthly production capacity of more than 5,000 square meters have stable quality control. Those workshops that rent small warehouses cannot even get aging test workshops.
- Check the certification system: ISO9001 is the bottom line, CE certification determines whether it can be exported, CCC certification is related to electricity safety, and none of them are missing
- Focus on the technical team: The 24-hour response team is more realistic than sales. If you encounter a sudden black screen, you can be present in two hours.
There is a cold knowledge: some industrial parks in Qingxi have "hidden champions" of LED screens. Their products are exported to Japan and South Korea all year round, but the domestic market is low-key. The quality inspection standards of this type of manufacturer are 30% higher than that of the national standard. For example, outdoor screens require 72-hour salt spray testing, which is three times more time than conventional testing.
Five iron rules to avoid pits

Don't be fooled by "pixel spacing"
The smaller the parameters of P3 and P4, the better. Installed on a 20-meter-high roof screen, it is more cost-effective to use P6 than P4 - the human eye cannot tell the difference at all from 15 meters away, but the price can be saved by 40%. A building materials market owner suffered a loss and insisted on installing a P2.5 screen, but he spent 20,000 yuan more electricity bills every year.

Waterproof grade hides tricky
Those who claim to be IP65 protection should be asked to disassemble the box to see the structure. The truly qualified outdoor screen will be sealed with "sandwich": the outermost layer is an anti-UV adhesive strip, a nano-hydrophobic coating is sandwiched in the middle, and a flow channel design inside. During the typhoon season last year, there was a screen on Qingxi Avenue because the drainage hole was unreasonable, and the accumulated water poured back into the power module.
-
Brightness adjustment should be intelligent
Set 5000nit during the day to be dazzling, and do not transfer 800nit at night to wait for residents to complain about light pollution. Nowadays, high-end control systems all have light sensor probes, which can be automatically adjusted according to the environment, and are ten times more reliable than manual control.
-
Check the details of the installation plan
The kind that makes you hang it directly on the wall is absolutely unprofessional. Formal practice, load-bearing inspection must be performed first, and 20% of the margin must be reserved for steel structure brackets. Do you know why a shopping mall in Qingxi tilts the screen that has just been installed for three months? Because the weight of the device when the ad screen is updated is not included.
-
After-sales terms and phrases
"The three-year warranty and three-year full warranty are different, and the maintenance fee can be less than five digits. The focus is on whether labor costs are included, whether the fault type is limited, and whether there is a backup screen to provide.
Hidden Easter eggs for service processes
Following the right supplier can unlock many value-added services. for example:
- Content Hosting: Some manufacturers can save 100 creatives for free and update them at any time
- Energy consumption monitoring: The background can check the real-time power consumption of each screen, and automatically alarm for abnormal electricity bills
- Anti-theft tracking: Built-in GPS positioning. Last year, a screen in Qingxi was stolen in the middle of the night. It was recovered in two hours with this function.
There was a restaurant chain boss's slutty operation: he asked the screen to display Meituan scores simultaneously, and the manufacturer directly connected him to the API interface, and the negative review rate has now dropped by 40%. Many small shops could not imagine this way, but professional companies have already prepared ready-made solutions.
Self-question time
Q: How to determine if it is an OEM product?
A: I will teach you a ruthless trick - let sales take you to see the production assembly line. Real manufacturers have SMT patch machines, and fake manufacturers only use soldering irons to solder components. Check the LOGO on the control card again. Many copycats even have polished driver chips.
Q: How to choose if you have a limited budget?
A: Focus on cutting the auxiliary functions. For example, don't use touch interaction, save 30% of the cost ； Choose a common drive plan, and the electricity bill is half as high as a common drive. If the money is really tight, you can consider the rental model. You can use the new screen if you pay a few hundred a month.
Q: What to do if there is a sudden failure?
B: Remember the three emergency measures: first cut off the power to prevent short circuits, shoot the faulty video and send the technical group, and use the backup signal line to test. The screen at the last Qingxi exhibition was black, and it was just that spare wires saved the scene to avoid losses of one million.
Editor's opinion
Finding LED screen suppliers in Qingxi is like rushing gold, and you have to screen real gold in the roar of machines in the industrial park. Those who dare to show off the factory's production capacity, post inspection reports, and take you to see the aging workshop are the ones worthy of entrusting. Next time I see the LED sign flashing on the street with "clearance special offer", remember to ask first: Do you dare to take me to your workshop in Huike Industrial Park for a walk?
