Are you staring at your phone and worrying? I want to install a cool advertising screen for my store, but I’m afraid of being scammed. ； I have no idea how to choose an eye-catching display device for a company event. Don't panic! Today we will talk about this matter - especially those newbies who have no knowledge of the industry, how can they buy a reliable small LED display?

Two days ago, I helped a friend who opened a milk tea shop choose equipment and found that the LED screens on the market ranging from a few hundred yuan to tens of thousands of yuan can be called "professional grade." A boss showed me a link to a certain product on his mobile phone: "This one only sells for 888, and it says it has a P3 high-definition screen!" "After careful questioning, it turned out that it was not even basically waterproof, and it would probably be scrapped after three months if placed next to the milk tea operating table. So,​ ​When buying a small LED display, you can’t just look at the price. The key is to look at these five hard indicators.​​...

​​First look at certification qualifications​ ​: Just like buying home appliances requires CCC certification, LED screens from serious manufacturers must have quality management system certifications such as ISO9001. Especially for outdoor use, it must reach at least IP65 protection level (dustproof and waterproof). Some small workshops have beautifully written product parameters, but when they actually use a water gun to flush the product, the screen goes black.

​​Brightness adjustment is a science​ ​: A screen brightness of 800-1200cd/m² is sufficient for indoor use. If it is placed in a window exposed to direct sunlight, it must be at least 4000cd/m². There is a pitfall here - some merchants promote peak brightness as normal brightness, but after buying it, they find that it does not meet the needs of daily use.

I saw a case a while ago: a convenience store chain installed 20 poster screens, and after three months, color aberration appeared collectively. It was later found out that the driver chip had cut corners, resulting in inconsistent attenuation speeds for the red, green, and blue colors. so​ ​Chip brand and driver solution​ ​Be sure to ask clearly. It is best if you can watch the prototype live and play continuously for more than 8 hours.

In terms of price, let me give you a reference range:

• Below 5,000 yuan: basically second-hand refurbished or low-end assembled products
• 8,000-20,000 yuan: regular commercial grade, suitable for daily display in stores
• More than 30,000 yuan: with special functions (such as high permeability, special-shaped splicing)

At this point, some people may want to ask: "Can I buy those low-priced screens online?" "Let’s put it this way, last month a customer bought a batch of promotional screens at a cheap price and found out:

1. The so-called "three-year warranty" actually only covers the motherboard
2. During installation, it was discovered that the box size error was 3 mm, resulting in obvious seams.
3. After two months of use, 16 dead spots appeared, and the manufacturer asked for repairs at their own expense.

So,​ ​Don’t be fooled by low prices​ ​, it depends on the actual monthly production capacity of the manufacturer (a serious manufacturer has a monthly production of at least 5,000 square meters) and whether it has its own quality inspection laboratory. For example, there is a company in Shenzhen that focuses on exports. Their display screens can even control the pad spacing to 0.3 mm. Screens with this level of craftsmanship will not change color after five years of use.

Installation and maintenance must also be considered in advance. A gym owner complained to me that he had to readjust the color of the stage floor tile screen he bought every time it was disassembled and assembled. Only later did he discover that the box connector was not up to standard. It is recommended to choose a model with a quick disassembly and assembly structure. It is best if the manufacturer can provide localized technical service support - in case of emergency, it is really reliable to be able to come to your door for repair within 24 hours.

There has been an interesting trend recently. Many businesses have begun to use transparent screens for window displays. The light transmittance of this kind of screen can reach 86% during the day, and it automatically switches to advertising mode at night, which does not affect lighting and can attract customers. But be careful,​ ​Transparency and display effects go hand in hand​ ​, don’t believe those nonsense that says “90% light transmittance and 4K display”.

Finally, let me tell you a true story: Last year, there was a cosmetics store in Myeongdong, Seoul. The LED window screen installed was not sensitive to the automatic brightness adjustment, and the advertisements at noon could not be seen clearly. Later, I switched to a reliable supplier, and the screen could automatically adjust the brightness to 16 levels according to the intensity of sunlight. The store entry rate increased by 40% that month. So,​ ​Intelligent light sensing system​ ​It is now standard equipment for good screens.

Editor's point of view: Novices who want to buy small LED displays should remember three dos and don'ts - look at actual cases, factory inspection reports, and sign a detailed warranty agreement； Don't believe in verbal promises, don't buy cheap products, and don't ignore the suitability of the installation environment. If you are really unsure, choose those manufacturers that supply Japan and South Korea. These mature markets have strict quality requirements, and products that can pass the test will basically not fall into the trap.
