Do you often watch short videos and see the cool transparent screens in shopping malls, or are you shocked by the stage with the entire floor glowing at a concert? Behind these eye-catching visual effects is the same black technology - LED display. But here comes the problem. Searching for "LED screen" on the Internet will pop up hundreds of manufacturers, with prices ranging from a few thousand to millions. How should a novice choose to avoid getting into trouble? Don't worry, let's break it up and talk about it today.

Let’s talk about the most common application scenarios first. Rolling promotional information at the entrance of the street milk tea shop​ ​poster screen​ ​, advertising in the subway station​ ​HD large screen​ ​, these are all basic models. but if you have seen​ ​Transparent window screen with 86% transmittance​ ​, or one that can change colors according to the DJ’s rhythm​ ​dance floor tile screen​ ​, you know that LED is no longer a simple "light-emitting panel". A manufacturer that makes plans for Southeast Asian shopping malls revealed that they installed​ ​Curved advertising screen​ ​After playing the dynamic content, the store's traffic increased by 30% - you see, choosing the right screen can really bring real money.

Don’t be fooled by the technical parameters. The easiest pitfall for novices is to only look at the price without looking at the configuration, just like when buying a mobile phone, you can’t just look at the memory size. for example​ ​Refresh rate 1920Hz​ ​If this indicator is lower than this number, the captured video will be full of ripples. besides​ ​Smart brightness adjustment​ ​Function, if the indoor screen is adjusted to 1200cd/m², it will be like turning on a bathroom heater, but if the outdoor screen is less than 4000cd/m², it will not be visible at all under the sun at noon. A customer complained to me that the screen he had bought cheaply had color patches peeling off during the rainy season - and later I found out that the packaging process was not up to standard.

When it comes to purchasing channels, there are currently three main ways:

1. ​​Factory direct sales​ ​(Suitable for engineering projects, you can get the ex-factory price)
2. ​​Regional agent​ ​(Local service is fast, but the price may increase by 30%)
3. ​​E-commerce platform​ ​(The risk is high, the most outrageous case I have ever seen is that the wrong model was shipped and no refund will be given)

There is a factory in Shenzhen that is quite interesting. They have made a​ ​24-hour technical response​ ​, no matter how big the time difference is, the video guidance is all-inclusive from installation to debugging. Last time there was a stadium project in Tokyo, the construction team called at three o'clock in the morning to say that the cabinets could not be connected, and the engineer just kept the video on with them until dawn - this kind of after-sales service is really reliable.

You may want to ask:​ ​How to judge the strength of a manufacturer? ​ ​ Let me teach you a trick, just ask if you can see the real-time monitoring of the production workshop. A truly confident manufacturer, in the workshop​ ​Fully automatic placement machine​ ​and​ ​Aging test room​ ​Definitely well equipped. For example, there is a company with a monthly production capacity of 10,000 square meters. Each screen must undergo a 72-hour non-stop lighting test before leaving the factory. Only products made with such sincerity can withstand the torment.

In the end, the editor feels that choosing an LED screen is like looking for a partner. Don’t watch the hype from the ads, watch it​ ​Is there ISO9001 certification?​​，​​Do you dare to provide a five-year warranty?​​，​​Can you come up with real implementation cases?​ ​. After all, no one wants the screen to suddenly go out on opening day, right? Next time you see a merchant that advertises "the lowest price on the Internet," remember to ask them if they dare to slap their quality inspection report on your face.
