Hey, have you ever stared at the big LED screen in the mall in a daze? Just the dazzlingly bright advertising screen, there are always a few yellow metal pieces on the corners, which look like a gold edge on the screen. Let's talk about this today​ ​Copper corner​ ​The trick is guaranteed to let you slap your thighs after reading it: "So that's the case! "

1. What is copper horn?

Let's leave the words here first:​ ​The copper corner is the conductive metal part on the frame of the LED screen​ ​. This thing is usually hidden in four corners of the screen, and it looks like copper but is actually a special alloy. Don't underestimate these metal pieces, they are the "power transfer stations" of the entire display.

For example, it is like when we need to plug in a charging port to charge a mobile phone, the LED screen needs to be connected to these copper angles. But they are much more advanced than mobile phone interfaces, so they have to withstand three mountains at the same time:

• Tens of thousands of volts are rising back and forth every day
• Temperature difference test of minus 20 degrees to 60 degrees
• Anti-corrosion when wind and rain

2. Why is this thing so important?

​​Copper angle is the life gate of LED screen​ ​! Let’s put it this way, the fence screen we installed for a stadium in Tokyo last year was almost ruined because the copper corner craftsmanship was not up to standard. Later, I changed the new plan, guess what? Now that people hold concerts every day, the screen has not had any problems for two years.

We broke it apart and broke it and said that the copper horns had to do several major things:

1. ​​Conductive as fast as lightning​ ​: The professional term is "low impedance conduction". When speaking, the current runs faster than Bolt
2. ​​Thermal dissipation is comparable to that of air conditioners​ ​: Can export the heat generated by the chip in a timely manner to prevent the screen from being heatstroke"
3. ​​Protect water without leaking​ ​: IP65-level waterproof and dustproof are all controlled by it
4. ​​Strong joint joint​ ​: Pair dozens of screens into a whole like a Lego, and the error must be controlled to the thickness of the hair

3. Does copper corner technology actually have a chain of contempt?

Now the industry plays copper corners in three levels:

1. ​​Bronze Player​ ​: Ordinary copper plating, green hair begins to grow in half a year
2. ​​Golden rank​ ​: Vacuum electroplating + antioxidant coating, can last for five years
3. ​​King level​ ​: Laser welding + nano coating, starting in ten years

To give a real case, the transparent window screen we made for a shopping mall in Seoul uses laser welding copper corners. As a result, the typhoon blew the entire piece of glass last year, and the copper horns were intact! Do you think this technology is awesome?

4. What tricks do newbies need to look at when purchasing?

When buying an LED screen, don’t just focus on the resolution. These copper angle parameters are the hard indicators:

• ​​Conductivity ≥58MS/m​ ​(The larger the number, the more you can withstand it)
• ​​Salt spray resistance ≥72 hours​ ​(A must-have screens by the sea)
• ​​Contact resistance ≤0.5mΩ​ ​(The smaller the more power is, the more power is saved)
• ​​The thickness of the coating is ≥15μm​ ​(Thinness can easily reveal timidity)

If the merchant is hesitant and unable to explain these parameters, you have to be careful. It’s like buying a mobile phone without asking about the processor model. Isn’t that waiting to be cheated?

Personal opinion time

After working on the display for more than ten years, I have figured it out:​ ​Copper corners are the conscience of LED screens​ ​! Some manufacturers cut corners to save costs, but users have various problems after spending a year or two. On the other hand, the outdoor large screens we made for Southeast Asia have a five-year warranty period that has been opened, and the copper corners are as bright as the new ones.

After all, this industry is about details. Just like the fully automatic quality inspection line in our factory, each copper corner has to pass five levels and six generals:

1. First, take a microscope to see if there is any sand eye
2. Then use high voltage electricity to torture"
3. Finally throw it in the salt spray box for three days
   Only those who can pass the test after such a struggle dare to send it to the customer. After all, it takes less than five years to install the display screen, so don’t you want to receive a repair call in the middle of the night, right?

Next time you see the LED screen, you might as well get closer and look at the brassy corners. Don’t look at them inconspicuous, there is a hard-core aesthetic of modern display technology hidden here!
