​​Alas, I want to install a large LED screen but I don’t know who to do it? ​ ​
A little boss who runs a milk tea shop complained to me two days ago that he spent 30,000 yuan to find a signature screen made by a small workshop. After half a year of use, he started to "blink" - it was lit up and destroyed, and he looked like Parkinson's! This is really not uncommon. Now 40% of LED screen failures on the market are not in a good way. Don’t panic, today we will break it apart and talk about how to find a reliable manufacturer.

​​Look at these three points and immediately screen out the unreliable ones! ​ ​

1. ​​Don't be too small in production​​: If the workshop is not as big as a basketball court, don’t think about it as soon as possible. At least a serious manufacturer must have​ ​Production base of 10,000 square meters​​, the monthly production capacity is less than 10,000 square meters, and the peak season is not enough to be placed
2. ​​More than 200 quality inspection list​​: Last week, I visited a factory and even the torque value of the screws was tested. This kind of seriousness made people feel relieved
3. ​​Don't just look at pictures in cases​​: Be sure to inspect the screen you are using on-site. Focus on touching whether the four corners are hot, and the color transition is unnatural when playing videos

(At this time someone must ask: Can you choose those with very low quotations online? Let me tell you a real thing - a manufacturer in a shopping mall was looking for cheap, but the screen was not waterproofed properly, and it was short circuited on rainy days and burned the entire line! )

​​The production process was originally carried out in four steps​​

1. ​​Don't be careless if you need to confirm​​：

• Indoor or outdoor use?
• How many hours does the screen light up every day?
• Should I resist the strong winds of level 9?
  Last year, the rental screen used in a music festival was not clear in advance and the equipment went on a collective strike in water, causing heavy losses.

1. ​​Design of the plan is very particular​​：

• The pixel spacing is accurate to the millimeter level
• The cooling system must account for 30% of the box space
• Power lines must be backed up
  There is a hot pot restaurant owner who insists on saving space to reduce the heat dissipation hole, but in the summer the screen is so hot that it can fry eggs.

1. ​​Focus on production quality inspection​​：

• 72-hour aging test cannot be saved
• Protection level is at least IP65
• Splicing error <0.1mm
  The most exaggerated quality inspection I have ever seen - throw the finished screen from 2 meters high and still bright when I pick it up!

1. ​​Professional installation and debugging​​：

• The voltage stability is measured three times
• The signal transmission distance must be measured
• Emergency power outage function must be tested
  On the opening day of a shopping mall, the screen was dark, and finally found that the electrician connected the zero-fire wire in reverse.

​​How to squeeze the price of water? Remember this formula​ ​
Reasonable quotation = basic cost × (1+difficulty coefficient) + after-sales service fee

• ​​Indoor screen​​: 8000-15000 yuan/㎡ (see clarity)
• ​​Outdoor screen​​: RMB 20,000-35,000/㎡ (just the protection level)
• ​​Transparent screen​​: Starting from 30,000 yuan/㎡ (transmission rate exceeds 80%)

The key point is here! When encountering these two quotes, hurry up and run:

1. Say "all-inclusive price" but not details
2. Promise a "five-year warranty" but does not contain a warranty scope
   Last year, a gym owner was cheated badly - the so-called "all-inclusive price" did not include the installation bracket, and in the end it cost an additional 30,000 yuan!

​​Only by speaking human words in a case can you be convincing​​

1. ​​Arc advertising screen​​: A 20-meter curved screen used by an international airport has a curved surface accuracy of 0.5mm/m. The picture is not deformed when the aircraft passes by.
2. ​​Floor tiles interactive screen​​: Induction floor tiles installed in children's playground can splash water when stepped on, and the passenger flow has increased by 40% directly
3. ​​Stadium fence screen​​: The fence screen used for professional competitions, it can still work normally by being hit by football 200 times, and its protective performance is excellent

​​Editor's opinion time​​
After working for so many years, my biggest feeling is——​ ​Don't try to be cheap​​! The gap between good screens and bad screens is like smartphones and elderly phones. Recently, a new trend has been discovered: more and more manufacturers are starting to do it​ ​Flexible screen customization​​, can make waves and cylindrical operations. But to be honest, ordinary merchants really don’t use these black technologies, and it’s better to understand basic parameters than anything else.

The last nagging sentence is heart-wrenching: When looking for a manufacturer, you must see if there is any​​24-hour technical response​​. Last time, a supermarket was shut down in the middle of the night. Fortunately, the manufacturer successfully restarted ten minutes of remote guidance, so it is impossible to lose money! Remember, good service is the bottom line. Do you think this is the reason?
