Alas, you have seen those naked-eye 3D large screens that exploded when you were watching short videos? The interactive floor tiled screen in the mall will follow the rhythm of music, and the ultra-clear background wall that can illuminate the eyes of celebrities at the concert... How do these cool LED displays come about? Today we will talk about the tricks of this industry.

1. What pitfalls are hidden in the production process

The most common question for beginners: Who should I look for if I want to make a LED screen? There are three main types of service providers on the market:

1. ​Pure processing plant​: Just welding the lamp beads according to the drawings, which is suitable for geek players who understand technology. However, last year, a bar owner designed the drawings and found that the color difference was like rainbow candy after installing them.
2. ​​Project Company​: All inclusive from design to installation, but the project may be subcontracted three or four times. A shopping mall atrium screen project was postponed for three months.
3. ​​Technical Manufacturer​: It has its own R&D team and installation qualifications, and can handle special shapes. For example​Arc screen bending technology​, can make the arc screen slit with a radius of 2 meters less than 0.5mm

Here is a cold knowledge:​Don't believe in the promise of "seven-day delivery"​! The regular P2.5 indoor screen will take at least 20 days from ordering to installation, and the light beads can be divided into more than 72 hours alone.

2. Choose a service provider and look at the hard indicators

Teach you three tricks to identify reliable teams:

• ​​Look at the workshop​​: A truly capable manufacturer dares to open production bases. Pay attention to whether the SMT patch machine is imported. The lamp beads attached to domestic equipment are prone to be welded
• ​​Investigate cases​: Requires to watch three videos of the same type of project, pay special attention to whether there are any color blocks at night
• ​Test the response​: Called at 10 o'clock in the evening and said that the plan should be changed in an expedited manner. Only those who can receive video conferences immediately will be considered as 24-hour service.

Let’s give a real comparison case:

3. Bloody and tears lessons from the installation site

Do you think the screen is done? Eighty percent of these minefields need to be stepped on:

1. ​Power supply configuration​: The 10㎡ P3 screen doesn’t look big, but it actually needs to be equipped with three-phase electricity. There is a hot pot restaurant that only two phases of electricity were pulled, and the screen was intermittently exhausted.
2. ​​Heat dissipation design​​: When installing the screen in the ceiling, you must leave enough 30cm of heat dissipation space. The screen in a live broadcast room has turned yellow for half a year. When I opened it, I found that the heat dissipation hole was blocked by the gypsum line.
3. ​​Inspection channel​: The screen that is more than 8 meters long must be left with a back door. Last time, a screen without a maintenance port was removed, so the entire wall had to be knocked on.

Special reminder: High-altitude operations must be based on the construction team.​Aerial work certificate​, Last year, a store found a "Spider-Man" to install the screen to save 2,000 yuan, but it ended up breaking the three-box module and losing 80,000 yuan.

4. Hidden needs of special scenarios

The production requirements of different places are very different:

• ​Restaurant​: You have to choose an anti-fume coating, otherwise the screen will be as greasy as a stir-frying pan for half a year
• ​​Gym​​: The box with a shock-resistant structure must be used. The vibration of the treadmill can shake out the ordinary screen with molar patterns.
• ​​Seaside scenic spots​​: Salt spray test must be performed, ordinary screens cannot survive the rainy season in the wet sea breeze

A classic case: a music festival used​Quick disassembly rental screen​, the background of the main stage in the morning, and it was disassembled into four mobile stages in the afternoon. This flexible gameplay is simply impossible to achieve the traditional fixed screen.

The editor said it's heart-wrenching

Looking for an LED manufacturer is like looking for a decoration team - no matter how beautiful the drawings are, it is better to go to their construction site to see the actual workmanship. Focus on the treatment at the joints of the box, and if you can insert A4 paper, you fail. Next time you see a popular landmark that will shine, you might as well get closer and see if the pixels are arranged in a neat manner. This is more realistic than any parameter. Remember, good screens are piled up by time and money, and those whose quotes are ridiculously low will cut corners where you can't see them!
