​​"When you go to the mall, you are always attracted by the cool big screens, but when it is your turn to pretend, you are blinded? "​ ​ I can't bear to hear twenty bosses complain about this. Last year, owner Zhang of the Wanda Golden Street milk tea shop suffered a setback - the screen he bought for RMB 80,000 could not be seen clearly during the day, and ended up being reduced to a decorative light strip. Today we’ll break it down and talk about it thoroughly, and I’m sure you’ll be clear about it after watching it!

Three wild ways to find sources of goods

Let me start with some trivia: 80% of the LED screens in shopping malls across the country come from the Pearl River Delta! But Xiaobai, don’t rush to Guangdong. These three ways are more reliable:

​​Method 1: Find a "second-rate dealer" and get slaughtered? ​ ​
Many decoration companies will package quotations, and the water here is very deep! Here’s a trick: ask for separate quotes

• Screen price
• Installation and commissioning costs
• Three-year maintenance cost
  Last year, the owner of a hot pot restaurant did this and found that the middleman took 30% of the price difference.

​​Approach 2: Is online purchasing a pitfall or a treasure? ​ ​
Among the top 10 merchants found by Moubao, 9 are OEM! Focus on these three indicators:

1. Actual factory video (requires machine tool operation footage)
2. Test report number (you can check the authenticity on the official website)
3. Project case address (preferably in the same city for inspection)

​​Way Three: The Law of Picking Up Real Fragrances at Exhibitions​​
A must-go to the Guangzhou Exhibition in March and the Shanghai Exhibition in September every year! Last year, I met a ruthless person at the exhibition. He directly took the brightness meter to the site to measure the parameters. When bargaining, he threw out the data and confused the sales.

Parameter selection life and death line

​​"The seller said that the P4 screen is sufficient and can be filled with full screen mosaics! "​ ​ This is the most common minefield for newbies. Remember this formula:
​​Best viewing distance (meters) = pixel pitch (mm) × 3​​

For example:

​​Brightness is the most evil parameter​ ​——Don’t exceed 1200nit indoors, otherwise customers will have to squint while shopping! However, many unscrupulous merchants will brag about the peak brightness as a normal value. Remember to ask to see​ ​8 hours of continuous working brightness​ ​Report

Guidelines for preventing rollover during installation

​​"The screen arrived, but the electrician said it can’t be installed? "​ ​ I just saw this last month:

1. ​​Load-bearing walls should be inspected carefully​​
   A clothing store planned to install a 10㎡ screen, but found that the light steel keel ceiling could not support it. Finally, it was changed to 8 independent small screens to pass the test.

2. ​​The thicker the power cord, the better​​
   It is sheer waste to use 6 square meters of lines for a 5㎡ P4 screen, 4 square meters is enough. But don’t forget to install it​ ​voltage regulator​ ​——Voltage fluctuations in shopping malls can kill driver ICs

3. ​​signal interference prevention technique​​
   The wiring should be kept 50cm away from the central air-conditioning duct, otherwise the screen will be full of snowflakes.

Editor's opinion time

After seven years of working in the display screen business, I would like to remind you most:​ ​Don’t save money on after-sales service! ​ ​ The worst case I have ever seen was that I saved 5,000 yuan in maintenance fees, but ended up spending 38,000 yuan to replace the lamp beads the next year.

Nowadays, high-end shopping malls are using interactive screens. Although they are 40% more expensive than ordinary screens, the traffic-draining effect is really good! If you look at the screens that allow customers to scan codes and interact, the average time they spend in the store is two minutes longer.

Finally, I would like to say something from my heart: buying a screen is not the end, content operation is the way to go! It is recommended to update the screen at least three times a month and make dynamic special effects in conjunction with holidays - to ensure that your store can become the C-position of the mall!
