Xiao Wang, who just opened a store, stood in an empty store and was worried - he wanted to install a dynamic advertising screen. He searched dozens of pages of products on Taobao, with prices ranging from thousands to hundreds of thousands. Some people in the comment section said, "It takes three months to spend the screen", while others praised "the effect is comparable to that of a big shopping mall." How should I choose this thing? Don't worry, let's get to the point today.

1. There are more tricks in the parameters than you think

Last month, Lao Li, who helped open a milk tea shop, made a joke when he chose equipment. He bought a screen marked "HD" cheaply, but when the sun shone during the day, the pattern of milk tea was blurred like an abstract painting. Later, the inspection found that the brightness of the merchant's target 600cd/m² is laboratory data, and the actual use is only 400cd/m².

Remember these hard indicators:

• ​​Don't just look at the numbers in brightness​: The window position should be at least 1200cd/m², which is the same as turning on the maximum brightness of the mobile phone screen to bask in the sun
• ​​Refresh rate must be measured​: Those who do live broadcasts must choose ≥3840Hz, take a slow motion of the phone to shoot the screen, and there will be no ripple to pass
• ​​Pixel spacing to see the scene​: P3 (3mm spacing) is enough in the mall, and the jewelry counter must start with P1.5

There is a clothing store owner who has come up with new tricks. He installed a screen with somatosensory function in the fitting room, and he would automatically play out outfit videos as soon as he approached. ThisIntelligent sensor screen​It can bring 15% of the additional joint sales every month. You know, young people nowadays eat this set.

2. Don’t pay special needs

Boss Zhang of the gym recently encountered a problem - he wanted to install a screen on a curved column, but he asked the market that he could not make a curve. Later, I found a home that could customize 15° curved surfaces. It only took 5 days from measurement to installation. Now I have become an internet celebrity check-in point.

This is how special scenarios are done:

1. ​​Special structure​: Do 3D scanning model first, and the error is controlled within 0.5mm
2. ​Control System​: It must be able to display in different regions, such as broadcasting advertisements and QR codes at the same time
3. ​Maintenance channel​: Do not hide the maintenance mouth behind the decorative board, the master will come to the door and scold the streets

I heard that a hot pot restaurant has suffered a loss. Their picture looks good and embedded the screen in a carved wooden frame, but the heat dissipation is poor and the power supply is changed three times in half a year. Now that I've learned my lesson, I'll choosePre-maintenance designThe model can be repaired from the front if there is any problem.

3. Service guarantee hides a big pit

Last year, I helped my friend watch the mall event, but the screen suddenly turned black during the screen rehearsal. Contact the supplier and said that the engineer was in another place, and finally spent an extra 20,000 yuan deposit on temporary equipment rental. Now, let’s ask three things first:

• ​Response speed​: 2 hours of plan, 24 hours of people arrive at the site
• ​Remote Diagnosis​: Now it’s the 5G era, so you can solve it by restarting it.
• ​​Spare parts inventory​: The local warehouse has at least 10% of commonly used modules

Manager Liu of the wedding company is amazing. They always have 5 spare screens in the warehouse. When they encounter customers' temporary changes to their plans, they can change them with an electrician. Of course I have to buy itModular designThe products are as convenient as Lego.

4. The procurement channel is very deep

People often ask if buying online is more cost-effective? The purchasing manager of the home appliance store calculated the accounts for me: the same P2.5 screen has a 15% offline quotation, but it is required for three years of door-to-door maintenance; the online price is low, and installation and debugging are also calculated as the money, but it is even more expensive.

For channel comparison, see here:

There is a boss who does wholesale - directly connects with manufacturers through industry exhibitions, and saves middlemen, and the same budget can expand the screen area by 40%. However, they start from 500 square meters, so we can just take a look at it by small merchants.

In the end, the editor thinks that buying an LED screen is like finding a partner, and the most important thing is to be suitable. If you are in a hurry to use it, choose a local service provider, and if you need a special customization, you will directly find a R&D manufacturer. Three key points are: whether there are actual engineering cases and videos, whether you dare to visit the workshop, and whether you can sign a performance guarantee agreement. Next time, if you encounter a salesman who brags about not drafting, he will directly get the installation record within three months, so that he can definitely screen out 80% of the unreliable ones. By the way, don’t forget to ask for a photoelectric inspection report. This thing is much more effective than the merchant’s promise!
