Are you worried about choosing a display screen for opening a store to decorate? I was so dazzled when I saw various supplier advertisements, but I was afraid of getting a trap to buy "wedding screen" (the kind that broke after one week)? Don't worry, let's talk about this big problem today. I dare say that after reading this article, you can take at least three months of detours - this is not a brag. The mines I stepped on when I helped my friend choose screens last year were enough to write the "Encyclopedia of Avoiding the Pit".

1. Let’s tell the truth first: buying a screen is not about visiting the vegetable market

Recently, many people are asking: "How can novices quickly increase their fans? "I want me to say it, select the display screen and make an account——​ ​Don't lose money by greed for cheap things​​. Think about it, if you spend 30,000 yuan to buy a screen, it will be deteriorated after half a year. It is better to spend 5,000 more to buy a reliable one. Here is a real comparison of the group:

Last month, a hot pot restaurant owner complained to me that the screen I bought was cheap and would flash snowflakes on rainy days. The manufacturer is happy: "Dear, our screen is not suitable for outdoor use~" Isn't this cheating people!

2. Purchase three soul tortures

1. "Buy online or offline? "

This question is like asking "Is online dating reliable?" The key depends on how to operate it:

• ​​Buy online​​: Be sure to watch the real demonstration of the video, so that the manufacturer can measure grayscale and color transitions on site
• ​​Buy offline​​: Don't be fooled by the exhibition hall effect, and ask to see the same model of engineering cases to take pictures
  There is a trick: let the salesperson take a mobile phone to take a slow-motion video on the screen, and you can tell whether the refresh rate is enough or not.

2. "Is the parameters important or is it true that you see it? "

It is easiest for beginners to fall here. Remember these three life-saving parameters:

• ​​Refresh rate ≥1920Hz​​: Simple test method, turn on the phone camera and face the screen without ripple
• ​​Brightness adjustment range​​: The indoor screen is not automatically dimmed, it can be dazzling at night
• ​​Protection level​​: Outdoor screens must be certified IP65, otherwise they will be rogue

3. "Can custom screens be sky-high prices? "

Let’s put it this way, curved screens and transparent screens are no longer luxury goods now. For example:

• Regular straight screen: like buying ready-to-wear, the price is transparent but may not fit
• Customized special-shaped screen: like tailoring, 15%-30% expensive, but it can perfectly fit the space
  The wavy single-size screen made by a milk tea shop last year was 20% more expensive than the ordinary screen, and it turned out to be an internet celebrity check-in point, which is worth spending!

3. Hidden services that experts only know about

You may not know that reliable manufacturers hide these "invisible benefits":

1. ​​Free scene design​​: Don't underestimate this, professional lighting can increase the display effect by 50%.
2. ​​Remote diagnostic system​​: Black screen in the middle of the night? Engineers can troubleshoot power module failures online
3. ​​Spare parts pre-store​​: The favorite service of Southeast Asian customers, local warehouses always have consumable parts

A friend who works in a gym had a hole in the screen with a barbell. I thought it would be shut down for half a month, but the manufacturer adjusted spare parts in the local warehouse and repaired them in two days. So,​ ​After-sales service is the real kung fu​​。

4. The way in global cases

Recently, I found some interesting phenomena when I helped my customers inspect the market:

• The curved screens in Singapore shopping malls that "turn" are actually modularly spliced.
• The "transparent window screen" of the Japanese-Korea subway station is glass during the day and turns into advertising screen at night
• The fence screen used for international events can still see the expressions of athletes in heavy rain

These projects look high-end, but they actually use general technology. The key is that manufacturers must understand the industry - sports screens should be anti-glare, shopping mall screens should control heat dissipation noise, and there are many more things to pay attention to here.

The editor said it's heart-wrenching

Buying an LED screen is like finding a partner. Just looking at the appearance (display effect) is not enough, but also depends on the family’s financial situation (production capacity) and character (after-sales service). Those who promise "the lowest price on the entire network" will cut corners in places you can't see. Remember, there are two standards for good screens:​ ​It will still be stable in three years, but if something goes wrong, someone will care​​. If you are selecting a screen, you might as well ask more questions: "If this screen breaks in five years, is your company still there?" "
