Have you ever seen those "magic" smart LED screens on Douyin? Looking at the cool big screens in other shopping malls that can automatically adjust the brightness and remain clear even on rainy days, I was itching to buy a TV to start a business, but I searched online - What a guy! From a small copycat factory to a big international brand, if the price difference is less than a Tesla, the water is too deep, right? Don’t panic, today we will teach you step by step how to choose a reliable smart LED display.

Buying a smart LED screen is like looking for a partner

You must first find out your own needs. Just like looking for a partner, you can't just look at looks. When choosing a display screen, you have to focus on these hard indicators:

• ​​Brightness IQ​ ​: It can soar to 7,500 lumens during the day to combat the scorching sun, and automatically drops to 800 lumens at night without dazzling the eyes. This kind of adaptive adjustment is truly smart.
• ​​refresh rate bottom line​ ​: Watching motion pictures on a screen lower than 1920Hz is full of smear, which is the same effect as shooting a high-speed train with a classic mobile phone.
• ​​Protection level​ ​: IP65 is the starting price. It must be able to work normally in heavy rain to be considered qualified.

Last year, a friend who owned a hotpot restaurant bought a low-priced screen from an off-brand screen. As a result, the kitchen oil fumes smelt out of the kitchen, and the screen suffered from "Alzheimer's disease" in half a year - distorted colors and unresponsiveness. So​ ​Don’t just look at the price, the key parameters must be understood​​。

Factory direct purchase is the way to go

There are three main ways to buy a screen now:

1. ​​second-hand dealer​ ​: The price looks delicious, but there are more hidden diseases than the pepper in the hot pot base.
2. ​​middleman​ ​: Not to mention that the quotation is inflated, but after-sales kicking can cause heart attack.
3. ​​Source factory​ ​: Although you have to wait for the production cycle, the configuration can be customized and the after-sales service is guaranteed.

Here comes the point! There is a national high-tech enterprise in Shenzhen that specializes in LED displays, with a monthly production capacity of tens of thousands square meters, and has been supplying the Japanese and Korean markets for seven or eight years. Their smart screen has three killer features:

• ​​Military grade cabinet​ ​: The magnesium-aluminum alloy frame can be disassembled and assembled faster than Lego, and the rental screen will not deform after being moved ten times.
• ​​Whole process quality inspection​ ​: From the lamp beads to the power supply, the whole process is inspected three times, and the yield rate is 15% higher than the industry standard.
• ​​24 hours cloud control​ ​: The screen at the Tokyo Olympics venues was maintained remotely by them.

Please keep the pit avoidance guide

The three minefields that novices are most likely to step into:

1. ​​Only view the full screen price​ ​: I want to ask about the brand of lamp bead chips. Taiwan Epistar is 30% more expensive than other brands but it can last for five years without fading.
2. ​​Ignore the installation environment​ ​: Hot pot restaurants must choose oil smoke-proof models, and seaside shops must have anti-salt spray coatings.
3. ​​Don’t understand scene adaptation​ ​: The shopping mall atrium requires a small spacing of P4 or less, and outdoor advertising of P6-P8 is more cost-effective.

There is a case of blood and tears: a gym bought an ordinary screen-mounted swimming pool, but the water vapor corroded the circuit board, and hundreds of thousands of equipment were directly scrapped. So​ ​For professional matters, you have to find professionals​ ​, directly docking with the factory can save 80% of the worry.

How to break the price fog

Why can I buy a Wuling with the same P3 screen at a different price? The key lies in the invisible configuration:

• ​​driver chip​ ​: Gigabit streaming chips can play 8K without lag, while cheap ones can play 4K with frame drops.
• ​​Cooling system​ ​: The one with smart temperature control is 30% more expensive, but still as stable at 40 degrees Celsius as an old dog
• ​​Software ecology​ ​: Those that can connect to the Internet of Things platform are 50% more expensive, but can remotely manage the screens of the entire building.

Taking a common 10-square-meter outdoor advertising screen as an example, a reliable package plan (including three-year maintenance) ranges from RMB 150,000 to RMB 200,000. If you encounter a quote lower than 120,000, it is recommended to turn around and leave - either renovate the screen or cut corners.

Editor’s opinion: To be honest, the water in this industry is very muddy. But it’s right to remember three mantras——​ ​Check factory qualifications, read overseas cases, and try out actual results​ ​. The next time you encounter a salesperson who is exaggerating, ask him directly if he dares to sign a "full refund if the brightness does not meet the standard" agreement? If you don’t dare, change your home as soon as possible.
