Are newbies who are new to LED large-screen TVs often confused by these problems? The merchants searched online all say they are "the first in the industry". The dense "P2.5, refresh rate, and color gamut value" on the parameter table make people dizzy, and they are even more afraid that they will spend a lot of money to buy it and use it for three months? Today we will talk about something real and teach you step by step to avoid those pitfalls.

​​Let me tell you a heartbreaking fact first​​: Nowadays, LED screens are sold all over the streets, but it may be possible to count them with both hands that can really save you worry. Some merchants don’t even have a production line, so they just rely on reselling OEM products to make the difference. If there is a problem, they either push it to "the weather is too wet" or they will directly disappear. A friend complained to me two days ago that the color difference of the outdoor screen he bought was severe after using it for half a year. The manufacturer actually said, "This is normal aging"!

1. Find out what you want first

Don't rush to find merchants all over the world! The most common mistake that novices make is to look at the price first and not the demand. You'll find it clear:

• ​​Use scenarios​​: Is it a shopping mall that is promoting the wind and sun every day? Or do you have an occasional meeting in the company conference room?
• ​​Viewing distance​​: Customers stand 3 meters away to watch advertisements and sit 10 meters away to watch the scores of the stadium. The pixel spacing requirements are very different
• ​​Content Type​​: If high-speed sports screens are broadcast every day (such as racing live broadcast), the refresh rate is not 1920Hz or above.
• ​​Installation environment​​: Is the load bearing of the interior wall enough? Should I prevent typhoons outdoors? All these need to be thought clearly in advance

To give a real case: Last year, a gym insisted on installing an ordinary indoor screen as the background of the dynamic bicycle area, but the sweat vapor corroded the power module, and the repair cost was even more expensive than the screen! So, don't trust those merchants who tell you "you can use any scenario."

2. Where are the reliable merchants hidden

Now let’s talk about the key point - where should I find it? I have sorted out the pros and cons of three common channels:

1. ​​Online e-commerce platform​​
   The advantage is of course that it is convenient for price comparison and can also be viewed by user reviews. But be careful! Many businesses will take pictures of project cases, and the "customer photo" may not be their product at all. I will teach you a trick: ask the customer service to send live installation videos directly, pay attention to the splicing seams and picture fluency at the corners of the screen.

2. ​​Offline physical stores​​
   It is indeed more reassuring to see the display effect with your own eyes, but the store rental cost will eventually be transferred to the selling price. We must be more wary of those sales that are so grand in the exhibition hall but hesitate when asked about the technical parameters. They may not even explain the driver IC model clearly.

3. ​​Source manufacturer​​
   This is the most cost-effective choice, but you have to be able to choose. A truly capable manufacturer will have these characteristics:

   • Dare to show you the live broadcast of the workshop, the assembly line is all automated equipment
   • Do you dare to write specific values for technical parameters (for example, the brightness adjustment range is accurate to 800-1200cd/m²)
   • After-sales terms are clearly written into the contract (such as promised for 48 hours of home maintenance)

   Let’s talk about the last one. For example, some old factories that have been deeply engaged in the industry for more than ten years, their own R&D team can produce 3D renderings based on your site, and even plan the location of the distribution box for you. More hardcore will also provide training for customers to teach you how to use mobile APP to adjust color temperature - this service level cannot be imitated by OEM workshops.

3. Teach you three tricks to verify the correctness

Now we have reached the most critical part - how to judge whether the one you found is a real reliable merchant? Remember these three ultimate moves:

1. ​​Depend on whether the technical foundation is strong or not​​
   Ask these three questions directly:

   • What channel is the driver chip you use? (Professional manufacturers can report specific models)
   • How much is the dead light rate? (The industry standard is less than one in ten thousand)
   • Is there any low-bright high-gray technology? (This can ensure that the dark scene is not blurred)

2. ​​Check whether the service network is confidential​​
   Focus on whether they have service outlets in your area. There is a cold knowledge: manufacturers with excellent foreign trade are often more reliable, after all, the Japanese and Korean markets have abnormal and strict quality requirements. I heard that a Shenzhen company installed transparent screens for Seoul shopping malls, with a three-year failure rate. This level is a dimensionality reduction blow at home.

3. ​​Is the trial after-sales response fast?​​
   Pretending to ask a technical question, such as: "What should we do if the voltage on our site is unstable? "See if the other party directly throws you a voltage regulator link or asks about the circuit load situation carefully. A truly experienced engineer will remind you to do power redundant designs in advance, and this difference is like the difference between a roadside stall and a Michelin chef.

Finally, I would like to say my heartfelt words: Don’t be greedy for cheapness when buying LED large screens! Some of the quotes are ridiculously low, and they may be renovated with second-hand lamp beads. The most exaggerated case I have ever seen is that a cheap screen bought by a restaurant was connected to the power with the remaining wires from the decoration, and the result was a short circuit and caused a fire. Remember - leave professional things to professionals, from the design to the installation and maintenance, merchants with technical teams support the entire process, so that you can buy with peace of mind and worry-free.
