Do you guys often get crazy?——​​I want to install a large LED screen but I don’t know who is reliable to look for? ​ ​ Last week, a friend who opened a shopping mall complained to me that he spent 200,000 yuan to install the display screen, and his face was green when broadcasting videos! Today we will break it apart and say, and we will teach you to avoid all pitfalls like an old driver.

(Prepare your chest first to ensure it) Let me tell you a hard indicator: a truly professional manufacturer must have​​Automation workshop with a monthly output of 10,000 square meters​​and​​Full process quality inspection report​​. Just like when you go to the vegetable market to buy meat, you have to check if the stall owner has a quarantine seal, right?

1. Five common needs to be selected

1. ​​The shop door is eye-catching​​
   Want to create a moving billboard? ​ ​P4-P6 indoor screen​​The most suitable one is that the brightness of 800cd/㎡ is bright enough and not dazzling. A milk tea shop owner showed off to me. After he installed a 3-meter-wide curved screen, the average daily passenger flow doubled.

2. ​​Mall atrium building momentum​​
   Have to use it here​ ​Transparent LED video wall​​, the light transmittance must be >85%. A high-end shopping mall in Shenzhen installed this screen last year, and sales soared by 30% during holiday promotions - the key is that it does not affect lighting during the day and turns into a black technology show at night.

3. ​​Stage event bombing​​
   Pay attention to concerts or auto show! ​ ​Rental screen​​You should choose a quick-disassembly structure. Last time I watched an event, 8 people would build a large background wall of the basketball court in 2 hours. Focus on​ ​Refresh rate ≥1920Hz​​, otherwise the phone will be full of ripples when you shoot it.

4. ​​Live sports events​​
   The fenced screen in the gymnasium is the most challenging to quality, and it must withstand the audience's splashing of Coke + sun and rain. There is an IP65 protective screen for a stadium in Tokyo, which has not failed for three years - the secret of this screen is​ ​Aluminum magnesium zinc alloy box​​, 30% lighter than ordinary materials and more resistant to fabrication.

5. ​​Corporate exhibition hall town​​
   If you want to play high-end, choose​ ​Small pitch LED wall​​, pixels below P1.2 cannot be seen at all with the naked eye. A car company has built an 8K ultra-high-definition wall in the exhibition hall. When customers look at the car, they can see the reflection of the paint clearly, and the signing rate directly increased by 45%.

2. Three golden rules for choosing suppliers

1. Don’t be slutty when it comes to hardware strength

• ​​Production workshop​​: No direct pass without a 10,000㎡ automation production line
• ​​Quality Inspection Report​​: ISO9001 is the bottom line, CE and CCC certification are the plus points
• ​​Case library​​: Please watch real-time videos of similar projects, don't believe in the renderings

(Knock on the blackboard) The key point is:​​Requires a raw material test report​​! Last year, a customer found that the lamp beads used by the supplier were bulk new goods, and there was a color difference in half a year, and there was no place to cry when protecting rights.

2. Don't be lazy than technical parameters

Take a small notebook and write down these key indicators:

• ​​Refresh rate​​: Indoor ≥1920Hz, outdoor ≥3840Hz
• ​​Brightness adjustment​​: 800-1200 nits indoors, 4000+ outdoors
• ​​Protection level​​: The outdoor screen must be IP65, and the humid environment must be IP68.
• ​​Warranty Policy​​: The real big guy is the one who dares to promise a three-year warranty

Let me give you a negative textbook: A bar bought a low-cost screen, and the screen was seriously distorted when playing DJ, and the customer complained that it was watching a ghost movie.

3. Don’t be careless when checking the service network

A truly reliable manufacturer must do:

• ​​24-hour technical response​​: The display screen is black in the middle of the night? Remote guidance of engineer restart
• ​​Full cycle support​​: From design to installation and debugging
• ​​Localized warehouse​​: The urgent order arrives within three days, and the accessories can be replaced for a week

There is a cold knowledge: a screen in a shopping mall in Southeast Asia is filled with water, and the manufacturer directly airlifts the backup module, and the loss is controlled within 3 hours - this kind of service is really reliable.

3. The price is too deep? Teach you five tricks to prevent being slaughtered

1. ​​Don't just look at the unit price​​: Calculate the entire life cycle cost, including electricity and maintenance costs
2. ​​Beware of package traps​​: "Free design" may hide double profits
3. ​​installment​​: Leave 30% of the final payment and pay after acceptance
4. ​​Consumables touch​​: Ask Qinglung bead brand and power supply supplier
5. ​​Software charges​​: Is the intelligent control system charged separately

(Phone the thigh) Key reminder:​​Brightness attenuation curve required​​! Regular manufacturers can produce five-year brightness maintenance data, which is much more than sales bragging.

Personal opinion: The industry is reshuffling now

In the next three years, assembly plants without technology will be eliminated. Recently discovered a trend:​ ​Customers began to require the display screen to have data acquisition function​​. For example, retail stores need to count customer flow portraits, and concerts need real-time interactive data - this is not a simple display screen, it is clearly a smart terminal.

What's even more amazing is that there is a gym, which has a magic mirror screen installed at the door of the locker room, so that members can view physical test data by scanning their faces. So, looking for suppliers not only depends on manufacturing capabilities, but also on​ ​Is there any ability to integrate smart IoT?​​。

Finally, I'm heart-wrenching: Don't be fooled by the fancy functions, remember​​Stability and after-sales service are the best​​. Just like finding a partner, being handsome is not as reliable as you are. What can solve problems at critical moments is the real ability!
