Recently, many local businesses are asking, if they want to install an LED display screen in Gongqingcheng, how should they choose to avoid pitfalls? To be honest, this industry is very deep. A supermarket owner complained to me that the screen installed last year had color patches peeling off after half a year, and the repair cost was more expensive than buying a new screen. Today I will take you through the doorways here.

​​Let’s talk about the most important thing first – how to judge the screen quality? ​ ​
Ordinary consumers may not know that LED screens​ ​Refresh rate ≥1920Hz​ ​This is the passing mark. If you look at anything below this number for a long time, your eyes will get sore. Like the advertising screens used in supermarkets, the brightness must be​ ​800-1200cd/m²​ ​The range can be adjusted flexibly, making it bright enough without reflection during the day and not dazzling at night. The most outrageous thing I have ever seen is the screen installed in a certain store. It was not bright enough at noon, and the promotional information was blurred like a mosaic.

​​The installation location is particular​​
Suitable for cashier counter​ ​Ultra-thin poster screen​ ​, the thickness is controlled within 8cm； Must be used in the fresh food section​ ​IP65 waterproof screen​ ​, to prevent water mist erosion. Last year, a fishery shop owner tried to install an ordinary screen cheaply, but the circuit board rusted through in three months. More high-end now​ ​Aluminum magnesium zinc alloy box​ ​, comes with an anti-corrosion coating and will not rust after five years of use.

​​How to break the parameter comparison trap​​
Here are some tips for you:

• Let the manufacturer provide​ ​72 hours high temperature aging test report​​
• On-site touch screen body temperature (no more than 45℃ for 2 hours of operation)
• Check​ ​CE/CCC certification​ ​Original
• Test the uniformity of solid color images (reject color spots)

There was a milk tea shop owner who was very clever and asked to see the manufacturer's​ ​Automated production line video​ ​, it turned out that the other party didn’t even have a placement machine, and it was purely manual welding, so I passed on the spot. Now from a regular manufacturer​ ​The monthly production capacity exceeds 10,000 square meters​ ​, the workshop is all equipped with fully automatic equipment.

​​How to choose special scenes​​
If you want to do something fancy, such as a curved screen or a floor tile screen, you have to see if the manufacturer has one.​ ​3D modeling team​ ​. Installed in a bar last year​ ​Transparent screen with 86% transmittance​ ​, combined with the lighting effects, can directly increase sales by 20%. Although this kind of customized screen is more expensive, the eye-catching effect is definitely worth the price.

When it comes to after-sales service, there are some details to pay attention to:​ ​24 hours response​ ​Not a decoration. On a rainy night last month, the screen in a hotel lobby suddenly went black, and the manufacturer's technicians rushed to the scene within two hours with spare parts. Nowadays, reliable manufacturers dare to promise​ ​Three-year machine warranty​ ​, those who only guarantee for half a year are basically second-rate dealers.

Finally, a reminder for newbies: don’t just compare prices, calculate the general ledger. One gym bought a low-quality screen cheaply and had it repaired four times in two years. The repair cost was enough to buy two new screens. Remember these three elements——​ ​Check the certification first and then look at the case. The parameters must be measured and the after-sales service must be written in black and white.​ ​. The next time someone asks "Where can I find a reliable LED display in Gongqingcheng?", you'll know which weak points to keep an eye on.
