Oops, dear bosses! Are you worried about the big black screen in the shopping mall atrium? Two days ago, I heard a friend complain that the LED screen he spent more than 200,000 yuan to install, had a color block fault after half a year of use. The maintenance master came three times but failed to repair it. Let’s talk about it today. How should we choose a reliable team for storefront projects like shopping malls?

1. Three invisible mine zones for large screens in shopping malls

​​Q: The parameters are almost the same, why are the differences so big when used? ​ ​
This matter has to be said from the root. Last year, a second-tier shopping mall held a promotion, and the broadcast was broadcast on a large screen and suddenly became a PPT. Guess what? The problem lies in​ ​Refresh rate virtual standard​​! The merchant's target is 3840Hz, and the actual test is less than 1920Hz.

Several key parameters must be fought hard:

1. ​​Brightness adjustment range​​: The indoor screen should be at least 800-1200cd/m², and it must also be equipped with automatic light sensing adjustment.
2. ​​Grayscale​​: The screen below 16 bits, the dark picture is like a layer of gray
3. ​​Visual angle​​: The atrium ring scene must reach more than 170°, otherwise the corner shop will curse you

There is a cold knowledge: a truly professional team can do it​​Abortion Thermal Map Analysis​​, adjust the screen resolution according to the customer's stay position. For example, if you use P2.5 in the main passage and P4 in the elevator entrance, you will be worth the money!

2. Reveal the secrets of choosing a service provider

​​Q: How to tell if the other party is a bag company or is really capable? ​ ​
Teach you five tricks to verify your true self:

• Want to see​​Real shot of the production workshop​​Only manufacturers with monthly output of more than 10,000 square meters have stable quality control
• check​​Customs Export Records​​, the Japanese and Korean markets have strict quality requirements, and the exportable ones are not much worse.
• ask​​On-site case investigation​​, it is best to choose a rainy day to see the waterproof performance
• try​​Content debugging service​​, the professional team can calibrate the picture color in 20 minutes
• stare​​After-sales response speed​​, it is reliable to promise to be present 24 hours a day

I heard that a Shenzhen company made a curved screen for Southeast Asian shopping malls. It has not failed in three years of typhoon season. This kind of powerful person is the first choice!

3. Devil details of installation and maintenance

​​Q: Everything will be fine after installing the screen? ​ ​
Too naive! The most outrageous case I have ever seen: In order to save money, the mall does not install a heat dissipation channel, and eggs can be fried on the back of the screen in summer. These details must be kept in mind:

1. ​​Structural load bearing​​: It must be able to withstand a weight of 200kg per square meter (consider the crowded scene during holidays)
2. ​​Maintenance passage​​: Reserve maintenance space of at least 80cm wide
3. ​​Power supply wiring​​: Strong electricity and weak electricity must be divided into pipelines, otherwise signal interference can make you doubt your life
4. ​​Lightning protection measures​​: Copper core wire is required to connect flashers, and many teams use aluminum core to fool people

A shopping mall manager asked the construction party to apply fireproof coating on the steel structure, but it cost 20,000 yuan more, saving 80,000 yuan in fire insurance premiums every year. This is a good calculation!

4. Hidden gameplay of content operation

Don't think that the screen is finished! A certain internet celebrity mall uses this trick to increase customer traffic by 30%:

• Brand advertising at 10:00 in the morning (accurately reaching housewives)
• Cute pet videos during afternoon tea (attracting young people to take photos)
• Limited-time discounts are offered during evening rush hour (directly drive store conversion)
  The point is to bring​ ​Split screen interactive function​​, customers can upload photos to the designated area by scanning the code, which makes this gameplay sticky!

5. Look at future trends in advance

Now the industry is working on two new tricks:​​Transparent screen window​​and​​Floor tiles interactive screen​​. I heard that the latest technology can turn glass windows into display screens in seconds, and the transmittance can still be maintained above 85%. There are also manufacturers who have developed LED floor tiles that can bear 1 ton of weight, so that children are not afraid of being damaged when jumping.

But we don’t rush to pursue new things in our ordinary shopping malls. The best way is to make the basic screen first. Just like you have to master the heat first when cooking, it is not too late to serve those high-tech things when they become popular!

If you want me to say, choosing a shopping mall LED service provider is like looking for a decoration team, you can’t just look at the quotation. I have to go to the project site they have done, touch the screen seams, and see the nightly display effect. remember​ ​Good screen can speak​​, 4K promotional videos broadcast, if you can’t even see the texture of the silk clearly, change people as soon as possible! The last nagging sentence is that the contract must state that the lamp beads must be replaced for free during the warranty period, which can save a lot of maintenance fees!
