Buying an outdoor screen is like going on a blind date. How can you find a reliable partner?

Recently, a customer who works in a shopping mall complained to me: "There are as many LED manufacturers on the market as cabbage in the vegetable market, and the prices range from 2,000 to 20,000 per square meter. The water is too deep!" " This is true, but​ ​Master these three golden rules​ ​, ensuring you buy an outdoor screen that is both durable and affordable.

Rule 1: Read the "physical examination report" first before negotiating the price

What are you most afraid of when buying outdoor screens? ​ ​After half a year, it got water leakage and electricity leakage! ​ ​ Remember these​ ​Life-saving parameters​​：

1. ​​Brightness must be ≥5000cd/m²​ ​ —— It’s impossible to see clearly on a sunny day with less than this number, just like turning on the lowest brightness of your mobile phone to bask in the sun.
2. ​​The protection level should be IP65​ ​ —— Here are the secrets to working normally on rainy days
3. ​​Refresh rate ≥1920Hz​ ​ —— The secret to making videos without ripples, owners of live broadcasts should pay special attention to it

Let’s take a real case: the P4 curved screen installed in a pedestrian street last year, because the protection level was not paid attention to, the screen went black during the rainy season. The repair fee was enough to buy half a new screen...

Rule 2: The installation location determines the value of the screen

Don’t be in a hurry to ask for a price! Figure this out first​ ​Three installation elements​​：

• ​​Sight distance calculation​ ​: If the audience is 10 meters away from the screen, choose P6. You must go to P4 within 5 meters, otherwise the screen will be full of mosaics.
• ​​Load-bearing test​ ​: The steel structure must bear 80kg per square meter, so it can be as stable as an old dog during a typhoon.
• ​​Cooling reserve​ ​: Leave enough 1 meter channel behind the screen, which can lower the temperature by more than 10℃ in summer

There is a piece of cold knowledge that goes against common sense:​ ​Screens installed under the shade of trees are prone to damage.​ ​! Leaves drifted in and blocked the cooling holes, and the maintenance man shook his head when he saw them.

Rule 3: After-sales service is more important than the product

Here I’ll teach you how to see through the manufacturer’s​ ​Four major tricks​​：

1. ​​Warranty period​ ​: Only those who dare to guarantee it for 5 years are truly confident. Many small factories disappear in the second year.
2. ​​Response speed​ ​: 24-hour technical support is the bottom line, and it is best to be able to diagnose faults remotely
3. ​​Spare parts inventory​ ​: Ask if there is a local warehouse. No one can afford to wait three months for spare parts.
4. ​​Upgrade space​ ​: Screens that are compatible with future 5G+8K will really save money.

I remember there was a stadium project last year. Because I chose a supplier that did not have a local warehouse, I had to wait for two months to replace the power module, and the competition was over...

Personal opinion:

Buying an outdoor screen is like building a house;​ ​30% product and 70% service​ ​. I have seen too many people take advantage of the situation and suffer huge losses. In the end, the repair costs are more than the money saved. Next time you choose a supplier, ask them​ ​Operation and maintenance solutions for Southeast Asian projects​ ​——A screen that can survive high temperature and high humidity environments is definitely in your hands!
