Xiao Zhang, a new purchasing manager who just joined the industry, was so anxious that his mouth blistered recently - his boss asked him to purchase a 20-square-meter stadium fence screen, but the price difference between three suppliers was 150,000. Everyone would be confused about this matter. Let’s explain it to you today.​ ​The doorway to purchasing LED electronic screens​ ​, saving you three years of detours.

▌​​Three major minefields for online purchasing​​
Don’t think that everything will be fine just by searching for “LED display” on the e-commerce platform. Last year, the organizer of a music festival made enough mistakes on the B2B platform to write a textbook:

• ​​Parameter trap​ ​: An outdoor screen marked with a brightness of 4000cd/m², but the measured brightness is less than 3000.
• ​​Certification fraud​ ​: The PS marks on the CE certificate are more obvious than on the graduation photo.
• ​​Inventory virtual mark​ ​: A merchant that displays "1000㎡ in stock" actually needs to transfer goods from five warehouses.

Let me teach you a tough trick: let the seller take the photo​ ​Production line real-time video​ ​, focusing on the automated quality inspection process. The robotic arm grabbing speed in the workshop of a mature manufacturer can reach 12 modules per minute. This kind of production efficiency can ensure that urgent orders will not roll over for three days.

▌​​Tips for finding treasures through offline channels​​
Exhibition procurement is not just a business card book. Remember these three points in time:
① Contact the organizer one month before the exhibition to request​ ​Exhibitor List​​
② There is the most room for bargaining in the afternoon of the third day of the exhibition
③ Grab it two hours before move-out​ ​Last order sample screen​​

Last year, there was a smart man who was shopping at the Guangzhou Exhibition, focusing on those displays.​ ​Quick disassembly and assembly of the box​ ​stall. This engineering-grade product can be demonstrated on-site for disassembly and assembly in one hour, which is more effective than reading a ten-page product manual. Don’t forget to measure the seams of the screen body – if you can insert an A4 paper into it, the waterproof performance will definitely be compromised.

▌​​Life and death clauses in contracts​​
The most outrageous purchase contract I have ever seen.​ ​1920Hz refresh rate​ ​Written as "1920 frame rate". When signing a contract, be sure to pay attention to these five items:

1. Brightness fluctuation range ≤5%
2. Color temperature deviation value ΔE<1.5
3. Protection level test report (IP65 is not just a word)
4. Power module warranty starts from five years
5. Failure response time ≤ 4 hours

Let’s focus on the payment method: mature manufacturers dare to accept the terms of 30% advance payment + 70% acceptance payment. Those who insist on receiving the full payment are probably shady dealers.

▌​​Three tools for price negotiation​​

1. Use cases from the same area to lower prices: "Last month, the same size screen in XX mall cost XX million"
2. Using the payment cycle to exchange for discounts: "Can 50% down payment be reduced by another 3 points?""
3. Packaged after-sales service: "How much is it worth to train three operation and maintenance personnel for free?""

There is a cultural tourism project that saved a BMW by this trick: when purchasing a 200㎡ floor tile screen, the manufacturer was required to​ ​Intelligent brightness adjustment system​ ​Package it into the contract and save 20% of the electricity bill in the future.

Speaking of this, I think of a true story: a manufacturer made a transparent window screen for a Southeast Asian customer, because it failed to calculate clearly.​ ​Glass thickness corresponding to 86% transmittance​ ​, seven pieces of tempered glass were blown up during installation. So remember,​ ​The more powerful the parameters, the better. The key is to match the usage scenario.​​。

Finally, there is a shocking news in the industry: the official website of truly powerful manufacturers will definitely release​ ​24-hour real-time workshop monitoring​ ​. During the next video factory inspection, pay attention to the wearing rate of anti-static bracelets on the assembly line, which is lower than 90% for direct pass. After all, a company that can stably export to 110 countries has stricter production line management than the kitchen of a five-star hotel.
