Are you worried about your phone? The decoration company is urging us to set a display plan. The Internet search for "Indoor Full Color LED Display" has hundreds of manufacturers, and they all look the same. Novice is most likely to be confused at this time——​ ​Will the screens bought at a high price be like Internet celebrity filters? ​ ​ I understand this very much! Last year, I helped my friend open a hotpot restaurant to select screens, and I was almost cheated of 30,000 yuan. Today I will break these bloody and tears lessons and tell you.

1. Sprinkle cold water first: How deep is the water in this line

Recently, people always ask "How can novices increase their fans quickly" and ask me to say that choosing a display screen is the same as building an account.——​​Don't believe in the bright data​​. What do you think? Some manufacturers have beautiful screens in the exhibition halls, and the actual delivery may even have two levels of brightness. Here is a real comparison case:

Last month, a milk tea shop owner cried to me that the screen I bought would appear in color after three months of using it. The manufacturer is really: "Dear, ours is originally at home level..." But the quotation clearly stated "commercial screen"!

2. Purchase three soul tortures

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

Remember these three life-saving parameters and sales immediately know that you are aware of your skills:

• ​​Refresh rate ≥1920Hz​​: The real thing is to shoot videos without flashing the screen on your mobile phone
• ​​Intelligent brightness adjustment​​: 800-1200cd/m² interval, no reflection at noon, no dazzling at night
• ​​Grayscale​​: Starting at 16bit, you won’t have a “zombie face” when watching portrait videos"

There is a trick: let the sales live broadcast 4K food videos, and the steak oil flowers are clearly visible.

2. "Is the custom screen so expensive? "

Nowadays, the special-shaped screen is no longer a luxury:

• Regular square screen: like buying a finished suit, cheap but may not fit
• Custom curved screen: 15%-25% expensive, but it can fit perfectly on the column or bar
  The wavy course sheet screen I made for the gym last year, although it cost 20% more budget, the member check-in rate increased by 40%!

3. "Is it reliable to buy online? "

Focus on these three points:

• When inspecting video goods, you need to look at the production workshop, so that the automated assembly line will not easily produce defective products.
• Requires to see cases of the same type of scene and do not believe in the renderings
• Check certification: ISO9001 is the basics, and CCC certification represents complying with national safety standards

3. Hidden ways that experts know

You may not know that these "little tricks" are hidden in the good screen:

1. ​​Intelligent temperature control​​: When turning on the air conditioner in summer, the screen will automatically reduce frequency to prevent overheating
2. ​​Modular design​​: Which lamp bead is broken and replaced separately, without disassembling the whole piece
3. ​​Remote operation and maintenance​​: Black screen in the middle of the night? Engineers can restart the power supply online

There is a friend who works in an educational institution whose screen suddenly blacked during the epidemic. The manufacturer found out that the voltage was unstable in 10 minutes from a remote distance, so he guided them to replace the voltage regulator, saving 5,000 yuan in door-to-door expenses.

4. Real Kung Fu in Global Cases

If you look at these practical applications, you will understand the standards of good screens:

• The atrium ring screen in a shopping mall in Southeast Asia has not changed to the lamp beads in five years
• Navigation screen of Japanese and Korean subway stations runs for 18 hours a day as usual
• The splicing screen of the International Conference Center is operated for 8000 hours without fault

These projects look high-end, but in fact they have two core points:​​Stable hardware + reliable after-sales service​​. Especially in commercial places, the loss of screen shutdown may be half a month's turnover.

Let me tell you the truth

Choosing an indoor full-color LED screen is like finding a marriage partner. Appearance (display effect) is important, but living a life (long-term stability) is more important. Those who boast about "low price and high-end" will probably cut corners in places you can't see. Remember two hard metrics:​ ​Dare to provide five-year warranty and provide real-time technical support​​. Next time I meet a salesperson, I might as well ask directly: "The screen breaks in five years. Is your company still there? " As soon as you ask, Li Kui will immediately know whether it is true or not.
