Are you also worried - searching for "monochrome LED screen" on the Internet will pop up hundreds of manufacturers, but when you click on it, you either get technical parameters that you can't understand, or the customer service doesn't reply for a long time? A newbie wants to buy a reliable display screen, but why is it like looking for a needle in a haystack? Don't worry, let's talk about this matter today.

Let’s first talk about the use of monochrome LED screens. Although the streets are full of large color screens now, places like arrival reminders in the subway and promotional information at supermarket entrances need to display fixed content 24 hours a day.​ ​Red or yellow-green monochrome screens are the best​ ​. Why? The first is to save electricity, the second is to see far, and the third is to be affordable. Just like a novice who wants to quickly gain fans must find the right platform, when buying a display screen, he must first understand his usage scenarios.

So what hard indicators should you pay attention to when purchasing? Let me give you a practical list:

1. ​​The brightness should be sufficient​ ​: Starting from 800cd/m² indoors and at least 4000cd/m² outdoors. It can only be seen clearly under the bright sun.
2. ​​Don’t be greedy for small pixel spacing​ ​: Conventional sizes such as P10 and P16 are more convenient for maintenance
3. ​​The protection level cannot be saved​ ​: Only those with IP54 or above certification can withstand wind and rain.
4. ​​The control system must be stable​ ​: It’s really convenient to be able to update content remotely

Recently, a friend who owns a convenience store complained to me that the screen he bought from Xobao started to show black spots after three months of use. Later, I found a company that could provide it.​ ​Three-year warranty + 24-hour online guidance​ ​Manufacturer, the screen is still working normally after two years of use. So, buy this industrial grade product,​ ​After-sales service is ten times more important than price​​。

Here is a trick for everyone: ask the manufacturer directly for​ ​Real project case video​ ​. For example, actual photos of subway station installations and supermarket usage scene videos are much more numerous than brochures. Just like when buying a house, you need to see a real model room. Seeing is believing.

When it comes to installation and maintenance, many people fail at this link. There was a restaurant owner who bought a bare screen at a cheap price, but when he installed it, he found that he had to buy an additional controller and power cord. After all, it was more expensive than a complete set of equipment. So be sure to confirm​ ​Does the quote include a full set of accessories?​ ​, it is best to choose one that can provide​ ​One-stop service from design to installation​ ​of suppliers.

Finally, let me tell you the truth: Don’t believe those “black technologies” that are so hyped up. Monochrome screens are just a joke.​ ​Stable and durable​ ​. Finding a manufacturer with more than ten years of experience and ISO certification is better than anything else. Just like looking for old brands when buying electrical appliances, reliability is more important than anything else for a device like a display that will last three to five years.
