Recently, a novice friend sent me a private message in the background: "Where can I buy those cool big screens in the mall?" "That’s a good question! Just like how newbies need to master the platform rules to quickly increase their fans, there are also many ways to choose LED advertising screens. Today we will break it up and talk about this topic.

​​Let’s talk about the most common confusions first​ ​: Many shopping mall operators are exposed to LED screens for the first time and are easily confused by various parameters. The boss of a restaurant chain complained to me that he had liked a screen at an exhibition, but after installing it, he found that the brightness was not enough at all, and the display effect during the day looked like a mosaic. So, you really can’t be careless about purchasing.

If you want to avoid stepping into pitfalls, you must first understand a few key points. first is​ ​Brightness adaptation​ ​, Indoor advertising screens usually require a brightness of 800-1200cd/m², while outdoor environments must reach more than 4000cd/m² to withstand direct sunlight. Don't underestimate this parameter. Some manufacturers will falsely mark the value. At this time, it depends on whether there is a third-party testing report.

Let’s talk about it again​ ​Pixel pitch​ ​This matter. A simple understanding is the screen clarity. The smaller the number after P, the more delicate the display. P3-P5 is more suitable for shopping mall atriums. If used in window displays, you may have to choose smaller spacing. However, it should be noted that smaller is not always better, it depends on the viewing distance - just like a mobile phone film, there is not much difference between 1080P and 4K when viewed from 2 meters away.

There are three main product types on the market today worthy of attention:

• ​​Conventional advertising screen​ ​: Suitable for long-term fixed installation. Pay attention to the heat dissipation structure and dust-proof design.
• ​​Transparent display​ ​: Installed in the window, it does not affect the lighting. Now the high-end ones can achieve 86% transparency.
• ​​Floor tile interactive screen​ ​: Shopping mall atriums are very popular recently. They must be able to withstand the stampede of crowds and be non-slip.

Speaking of the pain point of installation and maintenance, there is a real case: a shopping mall bought a batch of screens, but after the rainy season, 30% of them had dead lights. Later, it was discovered that the packaging process was not up to standard, and this hidden cost was much higher than the original purchase price saved. So now those who know the business will ask suppliers for​ ​Five-year death rate​ ​Data that dares to promise to be lower than industry standards is considered reliable.

​​We need to focus on purchasing channels.​ ​. There are a dazzling number of online and offline channels now, but it is recommended that novices buy directly from the manufacturer. Why? Although middlemen offer low prices, they are prone to wrangling when encountering technical problems. If you directly connect with the R&D team, everything from solution design to installation and debugging can be handled in one go. Especially the special-shaped screen project cannot be completed without the support of the technical team.

Let me give you a reference range in terms of price (taking a 10-square-meter standard screen as an example):

• Basic model: RMB 80,000-120,000 (suitable for limited budget but basic display required)
• Mid-range configuration: 150,000-200,000 (with intelligent dimming and environment sensing functions)
• High-end customization: 250,000+ (special styling or interactive functions)

Finally, let’s talk about after-sales, an easily overlooked link. Really professional manufacturers will provide 24-hour technical response, and some can even diagnose faults remotely. Don't believe those "three-year warranty" clichés. Ask clearly that the warranty does not include labor and accessories. I heard that in some projects, after-sales maintenance fees alone account for 40% of the total cost. This money cannot be saved.

The editor feels that choosing an LED advertising screen is like looking for a partner. Parameter configuration is the hardware condition, and service support is the guarantee of life. Next time you go to the mall, you might as well pay attention to those always-on screens and observe their display effects and operation and maintenance status. Practical experience is more useful than any parameter table.
