Alas, recently someone always asks me: "Old Tiexin, I want to build an LED mechanical track screen installation in the mall. Where should I buy it? "This is really not something that can be solved by simply placing an order on Taobao. Think about it, this thing is a device that costs hundreds of thousands of yuan, but if you buy it wrong, you will be crying and fainting in the toilet. Don’t panic, we will break it and break it and talk to understand!

​​1. What kind of black technology is mechanical track screen? ​ ​
Let me give you some popular science first. This guy is not an ordinary LED screen. It can be like a Transformer​ ​Free expansion, rotation, and shaping​​, such as the wavy advertising wall in the shopping mall atrium, or the lifting background board on the concert stage. ​ ​Core three-piece set​​Remember:
• Alloy box with slide rail (five stars in resistance)
• Programmable control system (it must be ten times smarter than your smart speaker)
• Modular display unit (more convenient to disassemble and assemble than Lego building blocks)

Here is a cold knowledge: a good mechanical screen can work normally in the snow and ice of minus 20℃ and 50℃ sauna days. It depends on​​IP65 protection level​​and​​Wide temperature domain design​​Now. You may ask: "Where to check this parameter? "Don't worry, continue reading.

​​2. What hard indicators should you keep a close eye on when buying a mechanical screen? ​ ​
Visiting the market is like a blind date, it depends on the "hardware conditions". I'll make a list and remember to bookmark:

1. ​​Refresh rate ≥1920Hz​​(Below this number? The picture can make you doubt your life)
2. ​​Intelligent brightness adjustment​​(800 indoors starts at 800, and 4000 outdoors are the base, otherwise it will be a blackboard during the day)
3. ​​Box seams ≤0.1mm​​(If the seam is large, you can plug in bank cards, pass directly)
4. ​​72-hour aging test report​​(Not this? Lifespan may be shorter than that of internet celebrity stores)

For example, the screen bought in a shopping mall last year went on strike when the screen went black on rainy days. Later it was discovered that the protection level was false, and the turnover was lost by more than 300,000 yuan. So,​ ​Third-party testing report​​It's much more reliable than a salesperson's mouth!

​​3. Reliable purchasing channels are in full swing​​
Now the key point is here, where should I buy it? We have three situations:
​​Situation 1: Urgent use​​
→Find a local service provider with warehouses (save 3-5 days for logistics)
​​Situation 2: Customized​​
→Contact the factory R&D department directly (saving 15%-20% compared to the dealer's quotation)
​​Situation 3: Overseas projects​​
→Accept CE/FCC certification (must-have stepping stone for export customs clearance)

There is a secret in the industry to tell you:​​Manufacturers with monthly production capacity exceeding 10,000 square meters​​, the quality stability is at least two grades higher than that of small workshops. Why? On the automated production line, even the screws are screwed by robots!

​​4. Guide to avoid pits (Blood and Tears Experience Edition)​​
When buying mechanical screens, you are most afraid of encountering these pitfalls:
• ​​Quote play text game​​(Installation fee and software fee are calculated separately? )
• ​​Bluff with project cases​​(Remember the video factory inspection! )
• ​​After-sales response exceeds 24 hours​​(The most serious loss of chains at critical moments)

Last year, a friend was caught. The screen he bought was installed and the cable went out after three months. As a result, the manufacturer could not find anyone when moving the warehouse. So,​ ​24-hour technical response​​This must be written into the contract!

​​5. Hidden benefits that experts only know​​
Teach you three tips to save money:

1. The purchase price can be bargained by 5%-8% at the end of the year (you know what the manufacturer can do to achieve performance)
2. Three-year extended warranty will be given (10,000 less than buying a single person)
3. Bulk procurement can be negotiated for installment (relieving cash flow pressure)

There is an unpopular knowledge point:​​Support remote diagnosis​​The manufacturer can save you 70% of your travel expenses. Especially for overseas projects, the time lag party no longer has to get up in the middle of the night to repair equipment.

I personally think that buying an LED mechanical track screen is like finding a partner. You can’t just look at the appearance parameters, but also the reliability of "living a life". Next time you go to inspect suppliers, remember to focus on theirs​ ​Aging test workshop​​and​​Spare Parts Warehouse​​——Only these two places hide the real strength of the manufacturer. By the way, don't forget to let the technician demonstrate it in person​ ​Extreme Test​​, it is a mule or a horse, I will only know if I pull it out!
