Hey! Dear Shuangbai veterans, have you been itchy by the bright advertising screens on the street recently? Don't be in a hurry to pay, let's chat today——​ ​In our plateau climate with heavy winds and heavy rains, how should we choose an outdoor LED screen so as not to overturn it? ​ ​

1. When installing outdoor screens with double cypress trees, you must first look at the weather before eating.

First pour some cold water on Xiaobai,​ ​Our place has a high altitude and a large temperature difference, so not just any screen can handle it.​ ​! Last year, a supermarket in the county installed ordinary screens on the cheap. As a result, when the rainy season came, the screen performed "snowflakes falling", and the maintenance cost was more expensive than buying the screen!

​​Three localization indicators must be adhered to:​​

• ​​Brightness must be ≥5000 nits​ ​: Ultraviolet rays are strong on the plateau. Have you ever seen the screen reflect into a mirror at noon?
• ​​Protection grade at least IP65​ ​(Dustproof and waterproof are the bottom line)
• ​​Working temperature -30℃~60℃​ ​(Do you still remember the tragedy last winter when three screens were damaged by freezing at minus 20 degrees Celsius? )

2. The three major parameters will teach you how to distinguish between good and bad

Some people may want to ask: Businessmen say that their products are good, who should they believe? ​ ​Remember these three hard indicators, which is more reliable than calling your brother from sales:​​

​​1. Refresh rate ≥1920Hz is the threshold​​
If you see water ripples on the screen when taking pictures, just pass! Now high-end models can achieve 3840Hz and play racing videos without smearing.

​​2. Pixel spacing determines clarity​​
P6 (pixel pitch 6mm) is suitable for viewing from 15 meters away, and P4 is suitable for viewing within 10 meters. Have you ever seen a screen with soybeans filling the pixels in the square? That's because you chose the wrong spacing.

​​3. The power module must be double backed up​​
Voltage instability in plateaus is common, and automatic switching of dual power supplies can save your life. There is a hotel where the screen went black in the middle of the night because the power module burned out.

3. Three golden rules for finding manufacturers

Now comes the point! Where to find reliable sellers? ​ ​Collect these three tips to prevent pitfalls:​​

​​The first step: check qualifications just like checking household registration​​
ISO9001 is the basic one, and CE and CCC certification are indispensable. Last year, a businessman used a fake certificate to deceive people, but was reported for leakage during installation.

​​The second tip: Look at the case with positioning​​
The real boss is the one who dares to post on-site installation videos. Like the curved screen in Government Square that can withstand Category 8 winds, the entire process was broadcast live during installation.

​​The third tip: test the machine at full load​​
Don’t believe the showroom results! The screen must be allowed to play 4K video continuously for 12 hours. It will be obvious immediately whether the heat dissipation is good or not.

4. Hidden minefields in installation and maintenance

Do you think buying a good screen is enough? ​ ​These pitfalls will teach you how to be a good person in minutes:​​

• ​​The foundation needs to be treated to prevent settlement​ ​(The screen of a certain store tilted 15° after three months of installation)
• ​​The power cord must be made of flame retardant material​ ​(Ordinary wires age quickly and can easily cause fires)
• ​​After-sales service should include quarterly inspections​ ​(The plateau is very windy and sandy, and the cooling holes can be blocked by half a pound of soil every month)

Let’s take a real case: the brightness of the Internet celebrity screen at the entrance of the scenic spot dropped by 40% in two years because it was not regularly dusted!

5. Suggestions for vomiting blood from old purchasers

After working in this industry for more than ten years, I would like to give some advice to newbies:

1. ​​Don’t skimp on sample fees​​
   I would rather spend 2,000 yuan to send a sample than wait until the installation is completed to find that the color difference is like a color palette.

2. ​​The warranty scope must be spelled out in the contract​​
   Is it covered by water damage caused by heavy rain? Will I be compensated for lightning damage? Only in black and white is reliable

3. ​​10% balance must be left​​
   Wait for three months of stable operation before paying off. I have seen too many people who passed the acceptance test and then the screen was damaged after two months.

To be honest, buying outdoor LED screens in Shuangbai is like looking for a partner.——​ ​Just looking at looks is not enough, you have to be able to withstand the torment of firewood, rice, oil and salt​ ​. Next time someone brags about "the lowest price in the country" to you, just slap this in his face. Remember, a good screen comes with savings—saving worry, trouble, and maintenance costs!
