Sanyuan LED screen purchase guide, channel comparison, and complete analysis of purchasing key points

2025-07-25 167

Are Sanyuan’s friends often stumped by this problem? If you want to buy a reliable LED screen, you can’t find any way to go all over the building materials market. Don't worry! Let’s talk about this carefully today, and you will be sure that you feel like a mirror after reading it.

1. Three major ways to purchase physical stores

To be honest, the water in physical stores is very deep now. Last month, a boss who opened a supermarket bought a display screen for 80,000 yuan in Building Materials City, and the color difference occurred after half a month. Later I discovered that it was a refurbished logo. You have to buy screens in physical stores！

The key to these details:

Qualification wall must be viewed: Business license, 3C certification, and testing report are indispensable
Actual test of prototype brightness: Take the camera on the screen with your phone and shoot it, and do not use any horizontal lines.
Warranty terms and conditions carefully read: Pay special attention to the definition of "artificial damage". Some businesses even consider it artificial

Here is a cold knowledge: regular exhibition halls will be equipped with brightness testers, indoor screens are 800-1200 nits, and outdoor screens are 4000+ nits as the baseline. Those who cannot reach this number are mostly old stocks.

2. Five precautions for online procurement

Nowadays, young people love online shopping, but they dare not be careless about buying LED screens. Last year on Double Eleven, an internet celebrity bought a stage floor tiled screen on an e-commerce platform. The size difference was two centimeters apart when the goods arrived, and the shipping fee alone cost more than 3,000 yuan.

List of online shopping avoidances:

Parameters must have detection diagrams: Especially for the hard indicator of refresh rate ≥1920Hz
Watch the production video: Regular manufacturers have automated production line videos
Logistics price guarantee cannot be saved: The display screen is a precision instrument, so you have to buy enough screen breaking
Unboxing must be recorded: Record the entire process from unpacking to power-on
Payment in batches is the safest: It is recommended to leave 30% of the final payment and pay after acceptance

To give a real case: a 4K screen ordered online by a cinema in a certain county town, he specially asked to watch aerial videos in the factory, but it was found that the so-called "10,000-square-meter factory" was actually a stolen publicity material from other companies.

3. Special channels for engineering projects

If you are engaged in large-scale venue projects, ordinary channels will not be enough. Last year, the fence screen project of Sanyuan Stadium had more than 200 pages of technical requirements for the tender documents alone. This type of procurement requires professional route！

Special procurement process revealed:

The requirements list should be refined: Including protection level (such as IP65), box material (the best aluminum magnesium zinc alloy)
Sample test for one month: The real stress test needs to be run continuously for 720 hours
Installment acceptance system: It is divided into three stages: pre-acceptance, mid-term acceptance and final inspection
Technical resident must be signed: The manufacturer is required to send engineers to guide the installation on site

There is an industry secret here: many merchants who claim to be "customized services" actually receive orders and are subcontracted to OEM factories. Therefore, it is necessary to confirm whether the production address is consistent with the place of registration.

4. Tips for picking bargains in the second-hand market

Entrepreneurs who are tight-knitted often consider second-hand screens, but this industry is even deeper. There was a restaurant owner who bought a second-hand transparent screen cheaply. But when he turned on the power, he found that 15% of the lamp beads failed, and the maintenance fee was more expensive than the new screen.

Second-hand transaction anti-fraud guide:

Check age by serial number: LED screen life span is about 60,000-80,000 hours, be careful when buying it for more than 3 years
Disassembly to see the internal structure: Focus on whether the power module is original
With professional testing equipment: At least use grayscale test card
The transaction must be signed: Indicate liability for concealing defects

A key detail reminder: the second-hand screen modified with rental screens is the most deceptive! This screen looks new, but in fact, the box structure has been repeatedly disassembled and assembled, the screw hole position has long been loose.

5. Opportunities and risks of emerging channels

Now, LED screens are sold on live streaming, but there are more tricks here. A certain manufacturer sold "foreign trade orders" in the live broadcast room, but the results were all defective products that did not meet the export standards.

New channel identification method:

Check customs filing records: There are customs declaration forms for real foreign trade orders
To original packaging photos: Regular export products are all packaged in English
Voltage Compatibility Measurement: Japanese and Korean versions of equipment may require transformers
Check out the distribution of after-sales outlets: At least there must be a provincial maintenance point

Let me tell you a heart-wrenching fact: many of the so-called "factory direct operating prices" in the live broadcast room are 20% higher than the dealer's purchase price. What they earn is the information price difference!

Finally, let’s say heartfelt words: buying LED screens is not buying cabbage, don’t just look at the price. Now some merchants in Sanyuan are playing price wars, quietly changing the 500x500mm box to 490x490mm, which can save 15% of the cost. However, the flatness is poor when used and the splicing seams are obvious, which is a real loss. I'm going to say, I would rather spend more money to find a manufacturer with an independent production base. After all, the display screen will take several years to use. Do you think this is the case?
