Hey, I have been receiving private messages recently asking: "Who should a novice contact if he wants to buy a large LED splicing screen?" "This question is like asking "Which hotpot is the most authentic?" It's easy to say, but hard to talk about. Let me start with a heart-wrenching question: Do you know what is the difference between those large advertising screens in shopping malls that can deform and those low-quality screens that suddenly go black on the roadside?

​​Let’s talk about a real case first​ ​. Last year, a shopping mall wanted to create a naked-eye 3D effect. It purchased a batch of "highly cost-effective" large screens on an e-commerce platform for a cheap purchase. However, during debugging, it was found that there were always snowflakes flashing at the seams of the screen, and the brightness was not uniform. In the end, the entire project was delayed for two months, and the loss was enough to buy three more sets of equipment - you can see how costly it is to choose the wrong channel.

There are currently three main distribution channels on the market. Let’s compare them in the most straightforward way:

There is a piece of trivia that many people don’t know:​ ​A truly professional manufacturer, the official website has a real-time workshop live broadcast window​ ​. Just like when you go to a restaurant to see the chef, those who dare to show off the production line are the real ones. Pay special attention to whether there are hard-core configurations such as fully automatic placement machines and burn-in test rooms - these are directly related to whether the screen will fail after three years.

When it comes to installation, the most common pitfall for novices is to ignore it.​ ​Box structure​ ​. For example, if you buy a rental screen for fixed installation, the extra money will be enough to buy another 20% of the screen area. Here’s a tip for you: Check to see if the product is made​ ​Collision avoidance test report​ ​, especially those with arc splicing requirements, it must be confirmed that the tolerance of each cabinet is within 0.1mm.

​​Here comes the point​ ​! How to judge whether the manufacturer is really reliable? Remember these three "musts":

1. Must be able to provide live videos of projects of the same type (pay attention to the smoothness of the screen during playback)
2. The brightness adjustment range must be clearly marked (the values ​​for indoor and outdoor screens differ by seven to eight times)
3. A complete contract including installation and commissioning must be signed (many traps are hidden in clauses such as "hoisting fees are not included")

I recently discovered an interesting phenomenon: many customers have started asking to see​ ​Component purchasing list​ ​. This trick is really clever. Just like when buying a computer, you need to look at the CPU model. The core components of the LED screen, such as the brand of lamp beads and the model of the driver IC, directly determine whether the screen can be used for five years or two years.

Finally, let’s talk about an industry secret:​ ​The standard of screens exported to Japan and South Korea is 30% higher than domestic standards.​ ​. If you encounter a manufacturer that claims to be "exclusively for overseas markets", you might as well ask to see the customs declaration form - products that can truly withstand the inspection of developed countries are safe to use in local projects. By the way, I heard that some manufacturers have now developed smart modules with self-checking functions. When any lamp bead is broken, the mobile phone APP will directly alarm. This is a life-saving function for maintenance personnel.

Editor's point of view: Buying an LED splicing screen is like looking for a partner. Sooner or later you will regret it if it is cheap. Remember, the three elements of a good screen are always stability, stability, and TM stability! Next time you pass by a shopping mall and see those cool big screens, you might as well take a closer look at the seams - the one who can make you ignore the existence of seams is the real skill.
