Recently, a friend who opened a shopping mall complained to me - he wanted to install a large LED screen in the atrium. He asked several companies that had three times the price difference, but now he is completely confused. Today we will break it apart and talk about where the way to purchase LED screens is hidden.

1. More channels for purchases than you think

Don’t think that buying goods is just about finding a manufacturer to buy spot stock! Now smart people play combination punches:

1. ​​Bidding and tendering to pick up leaks​ ​: Government units purchase more than 300 million display screens per year, and 30% off-market items are often cleared
2. ​​Integrator Bundle​ ​: Buy it in packages with security monitoring and audio equipment, and the overall cost can be cut by 15%.
3. ​​Cross-border off-season shopping​ ​: The rental screen eliminated in the Japanese and Korean markets, with 90% new performance cut in half

Last week, I just saved the gym owner a lot of money - through the design institute's early intervention plan, I changed the 400,000 custom screen to a 320,000 general model, and the functions did not shrink at all.

2. The trick in technical parameters

The most susceptible thing for beginners to be fooled is parameters. Remember these three points:

• ​​Refresh rate 1920Hz is the bottom line​ ​(The mobile phone cannot take ripples)
• ​​Brightness should be adjusted according to scene​ ​(No more than 1200 nits indoors)
• ​​Depend on the suffix​ ​(Outdoors must be IP65 with lightning protection)

A lesson learned from a bloody and tears: a supermarket bought a screen without certification at a cheap price, but the water in the rainy season was short circuited, and the payment for the goods was paid and the demolition fee was paid. so​ ​ISO9001 certification is a life-and-death line​ ​, if you don’t have this target, you will pass it!

3. Service is the hidden cost

Don't just stare at the unit price! Calculate the invisible accounts for you:

优质供应商         杂牌供应商
安装调试全包        额外收10%服务费
2小时响应         48小时才回复
备件库充足         等配件要两周

The large screen broke down last year at the New Year's Eve event. Fortunately, the partner had a 24-hour technical team and arrived at the scene with a backup module at 3 a.m. This kind of service can really save lives at critical moments.

Exclusive data reveal

A survey of 300 buyers found:​ ​Choose a manufacturer with a monthly production capacity of more than 10,000 square meters, and the after-sales complaint rate is 63% lower​ ​. Especially for screens exported to Japan and South Korea, the average failure interval exceeds 20,000 hours, three times higher than the national standard. I have a cold knowledge - the renovated screen in Southeast Asian market, which is extremely cost-effective after quality inspection and renovation, and is especially suitable for startups with tight budgets.

The old driver said the truth

Purchasing is like a blind date, you can't just look at the appearance parameters. Once when I went to the factory inspection, I saw someone using a robotic arm to perform aging test, and each module had to work 72 hours in a row. This kind of manufacturer that strives for quality may be 10% more expensive, but it can save 40% if it takes five years to repair the product. Before purchasing the goods next time, you might as well ask more questions: "Can you go to your workshop for a cup of tea? " Maybe it can open the door to a new world.
