Hey, do you think the LED large screens that are often black and stuttered in the mall are so popular? Last week, I went shopping and encountered a shopping mall for promotions. As a result, the lower half of the main screen showed "50% off for the whole venue", while the first half was playing insecticide advertisements in a loop - this picture was so torn apart that it could make the customer confused. So choosing a reliable LED screen is a storefront project of the mall!

How many tricks have you ever been to the famous scene of a shopping mall screen?

1. ​​Not bright enough to become dumb during the day​​: Natural light at 10 am shines into the atrium, and the screen content is blurred into mosaics
2. ​​Color difference is out of control, comparable to abstract painting​​: The rose-red lipstick is displayed on the left, and the right turns into a phosphor
3. ​​Repairing the ceiling​​: Change the module and the entire area must be shut down for three days
4. ​​The electricity bill hurts​​: The monthly photoelectric fee for old-fashioned screens is enough to rent a new counter

I know a shopping mall operation manager. They changed the New Year decorative screen last year, and 16 stains appeared before the fifteenth day of the first lunar month were over. Later I found out that the screen protection level was not enough, so the cleaning lady bleeded in when she washed the ground. So,​ ​Selecting a screen in the mall is like finding a partner. Just looking at your face is not enough. You have to check your household registration book.​​。

This is how hardcore parameters are viewed

​​Don't be fooled by sales​​! These five key points that really affect the user experience:

• ​​Intelligent brightness adjustment​​: The indoor screen is best to automatically sense ambient light, the most eye-protective area is 800-1200cd/m²
• ​​Protection level must be double standard​​: IP54 dustproof + splashproof is the foundation, and catering floors must be selected for IP65.
• ​​Have enough maintenance channels​​: At least 80cm of operating space is reserved on the back of the box (don't ask me how I know)
• ​​Signal transmission needs to be redundant​​: The automatic switching of the main and backup signal source can be completed within 3 seconds
• ​​Comparison of energy consumption to see details​​: At the same brightness, you can save 1 kilowatt-hour of electricity per hour, which can save a piece of money on screen in five years.

There was a shopping mall that suffered a loss, and the screen refresh rate he bought was only 960Hz, but the customer took short videos with scan lines. Later I changed to the 1920Hz model, and now I can even do beauty live broadcasts directly in front of the screen - is this money worth it?

How to break the price fog?

Here is a look at the group's real comparison data:

The story of a high-end shopping mall is very interesting: they initially chose a normal screen to save money, but in the end, the repair fee for two years is enough to buy three new screens. Later, I cruelly changed the model with an intelligent temperature control system. I had no faults after three years of operation. Now it has become a golden advertising space that brands compete for.

Invisible service is the real skill

1. ​​Does the installation team have a high-altitude work permit?​​? (The shopping mall atrium is often more than ten meters high)
2. ​​Can after-sales service respond in 2 hours​​? (You can't wait for activities during holidays)
3. ​​Training packages or not teaching packages​​? (The new electrician must be able to operate it too)
4. ​​Is the accessories in stock enough​​? (Don't let customers wait for three months to import parts)

I heard that a shopping mall suffered a secret loss, and the screen itself was fine, but the installation team put the power cord and the water pipe on the same bridge, and the condensation caused the line to be short-circuited. Nowadays, reliable suppliers will send engineers to conduct on-site inspections, and even the location of the air outlet of the shopping mall must be included in the cooling solution.

My heartfelt words

Choosing a shopping mall LED screen is the same as choosing a smartphone——
✅ Don't just look at the parameters, but look at the actual case video (it's best shot at night)
✅ Confirm whether the manufacturer has a production base of 10,000 square meters (the quality of small workshops fluctuates greatly)
✅ Three major certifications must be checked: ISO9001 is the bottom line, and CE certification represents export quality
✅ Focus on brightness adjustment technology (real intelligence is the one that can automatically match morning and evening lighting)

Finally, let me tell you a cold knowledge: Many high-end shopping malls are now starting to use transparent screens with a transmissibility of 86% as windows, which do not affect lighting during the day and become advertising walls at night. The requirements for heat dissipation and structural design of this thing are more than one level higher than ordinary screens. Manufacturers who don’t have two brushes dare not take on such jobs.

Remember, a good screen is the second face of the mall. If you choose the right one, you can let customers stay for three more minutes. These three minutes are valuable!
