Do you often see the cool large screen on the roof of the mall or are attracted by giant billboards when you pass by the highway intersection, and mutter in your heart: "Where did you buy this kind of LED advertising screen? A bunch of manufacturers found online, with prices ranging from thousands to hundreds of thousands. Could it be all a trick, right?" Don't panic, let's talk about this today.

1. Buying a screen is like finding a partner, and the wrong channel is in vain.

Let me tell you a heart-wrenching fact first - 80% of the quality problems of LED advertising screens on the market are actually the source of the procurement channels. The most common mistake for novices is to either find small workshops for cheap purposes or get a 30% difference by middlemen. Here are some key points for you:

• ​​Engineering Channel​: Suitable for government projects or large commercial entities, people hold bid qualifications in their hands, but the project cycle may be delayed by half a year.
• ​Wholesale Market​: Electronic markets like Shenzhen Huaqiangbei are everywhere, and the prices are indeed attractive, but you have to know how to avoid refurbished screens
• ​​Direct Manufacturer​: Now many powerful factories have opened online flagship stores and can also inspect video factories, which is much more transparent than ten years ago.

For example, why can a curved advertising screen project done by a high-tech enterprise in Singapore operate stably for five years without any problems? The key is to directly serve one-stop services from R&D to construction, without the intermediate links to make batter.

2. How to break the price fog?

Why do some P4 outdoor screens of the same size quote 30,000 yuan, and some dare to ask for 150,000 yuan? The water here is very deep:

1. ​​Lantern Bead Mystery​: Taiwan crystal chips and miscellaneous chips have a lifespan of 3 times
2. ​​Case material​: Aviation aluminum-magnesium alloy and ordinary iron sheet have different typhoon resistance capabilities
3. ​Power supply module​: Intelligent temperature control system and ordinary heat dissipation, the electricity bill can make a difference in iPhone money every year

You will understand by looking at this comparison table:

Note that some businesses will sell indoor screens as outdoor screens, and this kind of screen will be closed in minutes when encountering heavy rain. I will teach you a trick - let the seller take photos of the inside of the box and see if the line is connected randomly like a spider web.

3. Choosing a manufacturer is more important than choosing a screen

Now I know why veteran drivers are staring at the manufacturer's strength? A reliable factory must have these hard conditions:

• ​​10,000-level dust-free workshop​​: The chip is covered with dust, and it will be a big black spot after half a year
• ​48-hour oven test​: The new screen needs to be run in a high-temperature room for 50℃ for two days before it can be considered as passing the test.
• ​​Full automatic calibration​: The era of artificial color difference has passed long ago, and now we have to use a spectrum analyzer

A cold knowledge that only an expert knows - see if the manufacturer dares to show it to youThree-year failure rate statistics table​. Those who dare to publicly promise that the death rate is less than 0.01% are really tough.

4. Installation and maintenance hiding great questions

Don't think that the screen is over after buying it. If you choose the wrong installation location, you will destroy everything directly:

• ​​Mall Atrium​: You must select a transparent screen with a transmissibility of more than 86%, so as not to block the merchant's lighting
• ​​Highway​​: The brightness must be 6000cd/m², and intelligent light sensing adjustment must be provided.
• ​​Sports Stadium​: The box must be able to withstand level 8 winds, and all bolts must be made of 304 stainless steel

Let’s focus on the after-sales service. A truly capable manufacturer will send engineers to conduct on-site inspections from the design stage, and even the local rainy season will be counted. After the screen is installed, you can also remotely monitor the temperature and humidity on your mobile APP, which is more attentive than yourself.

5. Buy online or offline?

This question is like asking "Is online shopping for home appliances reliable?" The key depends on the platform:

• ​​E-commerce wholesale​: Suitable for standard-size small screens, but the customization needs are basically unsatisfactory
• ​​Offline experience store​: Can watch the prototype on the spot, but it is easily deviated by sales rhetoric
• ​​Official direct purchase​​: Nowadays, manufacturers that pay more attention to have VR cloud factories, and even the production line can be broadcast live for you

Recently, there is a very interesting trend - many high-end screens exported to Japan and South Korea can find good prices on cross-border e-commerce platforms. Why? Because these factories want to leave profit margins for overseas customers, the online price is more realistic than offline.

The editor finally said something heart-wrenching: When buying LED advertising screens, you really can’t just look at the price. Next time I encounter someone with a very low quotation, why not ask them if they dare to sign?​Five-year contract for exchange​. Remember, a good screen is like a good car. It is expensive and cheap to buy. Those who buy cheap and expensive to buy eventually become "electronic waste" flashing on the street. You think so?
