Recently, many friends who own supermarkets are asking, why do other people's promotional advertisements always attract customers to stop? In fact, the secret may be on that moving screen. When it comes to "Where to buy LED rolling advertising screens in supermarkets", there are many ways to do it. Let's talk about this thing today that is both practical and easy to get into trouble.

Did you know that the advertising screens used in supermarkets are divided into three categories? Some screens begin to lose color after half a year, while others can last for five years without fading. The key depends on these hard indicators:

• ​​refresh rate​ ​: Your eyes will be tired after looking at a screen lower than 1920Hz for a long time.
• ​​Viewing angle​ ​: Horizontal 160 degrees is the basic requirement
• ​​Brightness adjustment​ ​: Automatically switch brightness during day and night
• ​​Protection level​ ​: At least IP54 dustproof and waterproof
• ​​Content management​ ​: Can I update advertisements remotely on my mobile phone?

A supermarket owner complained to me two days ago, saying that the advertising screen he bought became reflective in the afternoon, making it difficult for customers to see promotional information clearly. In this case, the wrong screen brightness parameter is most likely selected. The brightness of indoor supermarket advertising screens is controlled at​ ​800-1200cd/m²​ ​It is most suitable. If it is too bright, it consumes electricity and is dazzling. If it is too dark, it will not have a publicity effect.

When it comes to the choice of installation location, there is a lot of knowledge involved. The screen near the cashier should be thin enough, the screen hanging in the aisle should be light enough, and the screen in the fresh food area must be moisture-proof. The smartest design I have ever seen is to embed the screen on the side of the shelf, which does not take up space and can accurately push product information. Here is a reminder for novice friends: Never install the screen facing a window. Direct sunlight will cause the screen to age prematurely.

How to judge the screen quality? Let me teach you a simple method: touch the surface temperature of the screen with your hand. The surface temperature of a good LED screen does not exceed 45°C after 2 hours of operation. If it is hot to the touch, there is either a problem with the heat dissipation design or the use of inferior lamp beads. Another trick is to see if there are any color spots when playing a pure white picture. A screen with poor uniformity must have cut corners.

Nowadays, many manufacturers boast that their products can be controlled remotely, but in actual use, this is not the case at all. A truly reliable system should satisfy:

• Can be operated by Android/IOS
• Can be stored and played locally after being disconnected from the Internet
• Support video/picture/text mixing
• Ability to set different content by time period
• With real-time playback monitoring function

The case of a supermarket chain is quite interesting. They installed smart advertising screen systems in 20 branches and adjusted promotion content by analyzing customer flow data. As a result, sales increased by 18% that month. Is it worth spending the money? Therefore, when buying an advertising screen, you can’t just look at the hardware. The supporting software services are the added value.

Finally, a reminder to novice friends, don’t buy second-hand screens for cheap. The life of an LED display mainly depends on the attenuation of the lamp beads. The brightness of a second-hand screen may only be 70% of that of a new one, and the maintenance cost will be higher. It is recommended to choose to provide​ ​Three-year machine warranty​ ​Manufacturer, preferably one that can come to your home for installation and debugging. By the way, remember to ask the manufacturer to provide​ ​72 hours aging test report​ ​, this can effectively avoid quality problems.

After all, buying a supermarket advertising screen is like looking for a partner. You can't just look at the glamorous appearance, but also the inner strength and service guarantee. Next time someone asks "Where can I buy LED supermarket rolling advertising screens?", you will know to keep an eye on it.​ ​Brightness adjustment, heat dissipation design, after-sales service​ ​These three fatal points cannot be let go. Remember, a good screen speaks for itself, and the customer’s eyes are the best acceptance criterion.
