Manager Li, who has just taken over the renovation of the shopping mall atrium, has been so anxious that his lips are bubbled. He wanted a deformed LED floor tiled screen, so he asked the three companies that the price difference was 200,000. This industry is very deep, just like a novice always fears being cheated when buying jadeite, so you have to be very eye-catching when looking for creative screen supplies.

​​Watch the production workshop and don’t believe in promotional videos​​
A truly capable manufacturer has at least six fully automatic patch machines in the injection molding workshop. Last month, a developer was fooled to visit the factory, and the so-called "smart production line" turned out to be artificially soldered circuit boards. I will teach you three tricks to distinguish between true and false: 1. Touch whether the lamp beads in the raw material cabinet are vacuum-packed 2. Check whether there is an operation log of the aging test room 3. Check whether the warehouse preparations are full of three layers of shelves. Key reminder: Manufacturers with monthly output of over 10,000 square meters can customize 15 days faster than small workshops.

​​Customized processes hide cost black holes​​
If you meet someone who says "seven-day shipping", you will run away quickly. The eight necessary procedures for the formal regulations are: 3D modeling → mold opening proofing → lamp bead sorting → vacuum patch → 72-hour aging → waterproof testing → on-site splicing → color calibration. Last year, a shopping mall in Tokyo customized a wavy screen, skipping the waterproof test in order to save trouble, and the result was a short circuit in the rainy season of water inlet was 800,000. For special attention: creative screens with smart dimming (such as 1200 nits adaptation indoors), the debugging fee may account for 30% of the overall budget.

​​Qualification certificates need to be viewed at the latest version​​
The most outrageous supplier I have ever met, fooling customers with expired CE certification. Remember three key points: 1. The official website of ISO9001 certificate number can be checked 2. The test report has a CMA certification code 3. The driver IC must have EMC anti-interference certification. Now the power consumption of high-end creative screen drivers reaches 0.8W/㎡. If you fail to pass the energy efficiency certification, don’t touch it.

A boss asked: "How to judge the manufacturer's R&D strength?" He went directly to their laboratory and dared to demonstrate the special styling on the spot. Last year, the engineers in Dubai Mall's spiral screen project, in front of the customer, formed a perfect circle with a diameter of 8 meters in 25 minutes, and even credit cards could not be inserted at the joints. This practical ability is ten times more effective than sales bragging.

​​After-sales service hides real kung fu​​
Be sure to confirm three points before signing the contract: 1. Whether it is true and 24-hour response (requires to see the night service record) 2. Whether there is a module with the same specifications in the spare parts library 3. Do you charge transportation fees when you are on-site repairs. Everyone in the industry understands that manufacturers who dare to promise "full-cycle technical support" always have three specifications of driver ICs in the repair car. Just like last year's heavy rain caused a short circuit in a display screen in Seoul, the engineer took the waterproof box to replace it on the spot.

The latest industry data shows that the creative screen with fully automatic production has a failure rate of 67% lower than that of manual welding products. Those suppliers with too low quotes tend to cut corners on lamp bead sorting and packaging processes. The next time you bid, you might as well ask the supplier to demonstrate the 1920Hz refresh rate adjustment - the real ability is to be able to control the smear under high-speed cameras. After all, creative screens have to be built for a long time, and the maintenance costs saved are enough to buy three new equipment. Do you think this is the case?
