​​"Why are the models in the shopping malls dancing upside down? "​ ​ At a brand opening event last month, the misunderstanding of the 20-square-meter LED screen playing inverted, made the audience think it was a new type of artistic creation. Lao Liu, who has been working in the installation for eight years, told me,​ ​70% of the screen direction is wrong, there is no need to rework and reinstall it​​Today we will use the most down-to-earth method to disassemble the remediation secret of LED installation and reverse.

1. Three life-saving symbols for hardware installation

​​Core judgment​​: First find out whether the module assembly is reversed or the entire screen is inverted

1. ​​Light bead arrangement detection​​：

   • Normal situation: The lamp bead matrix is arranged from the upper left corner to the right
   • Installation feature: Incomplete pixel blocks appear in the lower right corner

2. ​​Power cord positioning method​​：

   • Find the interface marked "POWER IN" on the module
   • Correct direction: The power cord should extend from the right side of the screen to the left side

3. ​​Magnet test​​：
   Use a strong magnet to get close to the frame of the module

   • Normal installation: The magnet is firmly adsorbed at four corners
   • Reverse installation: The magnet can only absorb two diagonals

​​Blood and tears case​​: When a certain gymnasium installed a fence screen, the worker installed all 32 modules in reverse, and as a result, using software correction saved 18 hours of labor hours than disassembly and assembly.

2. Five magical operations of software correction

Alas, there is a key point here to draw a key point! ​ ​The rotation settings in the system can help urgently, but not life-saving​​：

​​Important parameters​​：

• The rotation angle compensation value should not exceed ±5°, otherwise there will be serrated edges.
• The color temperature compensation in HDR mode must be increased by 300K (for example, the original setting of 6500K needs to be changed to 6800K)

3. Self-question and self-answer first aid kit

​​Q: Will the reversed screen shorten the lifespan? ​ ​
A: It can be remedy as long as it does not exceed three months! But be aware:

1. The heat dissipation efficiency of the module installed in the inverted installation is reduced by 40%
2. It is recommended to adjust the brightness to 80% of the standard value.
   The inverted screen of a supermarket lasted for half a year. When it was removed, the attenuation rate of the lamp beads was 15% lower than that of the normal screen.

​​Q: How to avoid secondary anti-projection? ​ ​
A: Remember this formula:
"Go to the left, don't throw the label outward
The magnet attracts four corners, but the direction cannot be wrong"

​​Q: What should I do if the parameters are adjusted or the screen is splashed? ​ ​
A: Eighty times the signal line sequence is messed up:

1. Convert the A/B channel of the receiving card
2. Change the network cable interface from PORT1 to PORT3
3. After restarting, press and hold the setting key for 10 seconds to restore the factory

This is how I helped my friend repair the floor tiles screen at the concert last week——​​Sometimes metaphysical operations are more effective than technical manuals​​。

4. The golden rule of physical adjustment

​​Three situations that must be disassembled and re-installed​​：

1. The waterproof adhesive strip has been cured for more than 48 hours (forced demolition will tear the sealing layer)
2. Box structure with inclination locking device (commonly in arc screen)
3. The magnetic suction module falls off three times in a row (indicates the track deformation)

​​Lossless disassembly techniques​​：

1. First use a hot air gun to soften the glue strip at 60℃ (dry it in circles at a distance of 10cm)
2. Use the fishing line to cut the colloid horizontally (don't use a utility knife! )
3. The suction cup tool must be subjected to three Y-shaped forces

​​Thrilling moments​​: When the inverted screen of a shopping mall was removed last year, workers did not find hidden anti-theft snaps, and the deadlift caused the box to deform——​​So, when encountering resistance, look for hidden buttons first​​。

​​Editor's opinion​​
Handling the reverse screen is like treating a stiff pillow——​ ​It is better to find the right acupoint than to force it to correct it​​. Next time you encounter the image inversion, touch the power cord first and then move the software settings. Remember, if the screen with a quick disassembly structure has a frame temperature of 3-5℃ higher than the normal temperature, this is a hidden skill point to determine whether to install the reverse.
