Alas, what do you think of this LED large screen brand?

Recently, a friend asked me: "How do you know what brand of cool big screens in the mall?" To be honest, this question is like finding a partner - it depends on the details! Let’s talk about how to quickly lock its "id card" from a bunch of blinding screens.

The first trick: Find these "marks"

​​1. The mystery is hidden in the boot screen​​
Just like a branded logo on a mobile phone, many LED large screens will flash the manufacturer's logo when they are started. Last year, when I was watching a light show in Shenzhen Bay, I found an English trademark with a blue background and white characters flashed when the giant screen turned on. Later, I found out that it was a domestic brand that focused on exports.

​2. Find clues at the edges​
If you look at the screen border carefully, many manufacturers will stamp the brand steel stamps near the splicing seams. Once I helped my friend inspect the shopping mall advertising screen, and found the manufacturer number of laser printing in the snap position of the aluminum-magnesium alloy box.

​3. There is an article on the remote control​
The most amazing thing I have ever seen is a large screen in a stadium, with the brand abbreviation engraved on the back of the remote control using micro-carving technology. The staff said this was an anti-counterfeiting design and could only see clearly with a magnifying glass.

The second trick: check the parameters and know the details

​​① Brightness password​​
The indoor screen is generally 800-1200 nits, and outdoor screens require 4000 up. Last year, I installed an advertising screen for a hot pot restaurant and found that a certain brand’s parameters were false, and the actual brightness was less than 3,000, so I couldn’t see it clearly at noon.

​② Refresh rate mystery​
Those who go up 1920Hz must be professional players. I remember that the floor tiles screen of a music festival was not at all when the artist was dancing. Later, I asked the technical guy and found out that he was using a military-grade driver chip.

​​③ The protection level is true​
IP65 is considered an industry threshold. Once, when I passed by a commercial street during a typhoon, I saw a screen of a certain house that turned into a "pork face". Later, I found out that it was cutting corners and not sealing it.

The third trick: understand the pattern according to the service

​· Is the design thoughtful enough?​
Reliable manufacturers will bring spectrometers to measure ambient light. During the shopping mall renovation last year, a brand team took the illumination meter for three days and even considered the sunlight angle at different times.

​· Is the installation team professional or not​​
I have really seen a troupe who dares to take on the job with a toolbox. In comparison, regular soldiers will carry laser level and torque wrench, and even screw screws for several turns are standard.

​· Is the after-sales response fast?​
24-hour standby is not a blow. Once, the performance screen was halfway through in the middle of the night. The manufacturer's technician guided the restart of the control system in video, and it was done in ten minutes, which was faster than the delivery guy.

Personal opinion: Brands are important, but don't be superstitious

To be honest, the LED industry has long passed the era of buying goods based on brands. Just like the mobile phone circle, some technical streaming manufacturers who make a fortune in silence specialize in specific fields. For example, those who make stadium fence screens may be more reliable than those big brands with advertisements.

Recently I noticed an interesting phenomenon: many brands that have exported to domestic sales have higher parameters than domestic circulating products. For example, a company that focuses on the Japanese and Korean markets, its products have passed JIS certification, their salt spray resistance is three times that of the national standard, and their prices are even more affordable.

After all, choosing a large LED screen is like finding a marriage partner - you can't just look at the appearance or not, you have to look at the technical genes and after-sales service in your bones. Next time I encounter a salesperson who is full of money, remember to ask him for three years of failure rate statistics. This is the hard indicator that real gold is not afraid of fire!
