During the use of LED display screens, although we have taken normal operations, there will always be some uncontrollable factors, such as the awning being blown away by wind and rain, mice invading the interior of the display screen, water seepage, etc. These non-human factors may cause the display screen to be accidentally soaked in water.
So, when the LED display screen is soaked in water, how should we save it in time to reduce losses?
1. Preliminary processing and photo recording:
Send photos of the screen wading position, the front and back of the screen, and the air conditioner outlet and the screen to the after-sales staff for analysis so that they can give professional treatment suggestions.
Use a clean, lint-free absorbent towel or rag to gently wipe the wading part of the screen to absorb most of the water vapor on the surface.
Be gentle when wiping to avoid secondary damage to the screen
2. Dehumidification and drying Air conditioning dehumidification:
Set the air conditioners in front and behind the screen to run in 7×24 hours dehumidification mode, and make sure that the air outlet of the air conditioner is not facing the screen to prevent moisture from invading again.
Dehumidifier and fan: Place a dehumidifier and a fan in front of the screen to speed up the dehumidification process.
Dehumidifiers can effectively reduce the humidity in the air, while fans help speed up air circulation and promote the evaporation of water vapor.
Blow-drying with a fan: Use a fan or other tool to completely dry the damp LED display as soon as possible.
Use a fan instead of a hot air blower, because hot air may accelerate the aging or even damage the internal components of the screen.
3. Gradually brighten the aging process:
Gradually increase the screen brightness for aging. First, on the day of aging, adjust the screen brightness to 10%, perform video aging, and record the number of bad points.
On the second day, adjust the screen brightness to 30%, perform video aging, and record the number of bad points.
On the third day, adjust the screen brightness to 60%, perform video aging, and record the number of bad points.
On the fourth day, adjust the screen brightness to 80%, use 150 grayscale white screen aging, and record the number of bad points.
On the fifth day, adjust the screen brightness to 100%, use 200 grayscale white screen aging, and record the number of bad points.
Power off and aging: On the fourth and fifth days, ensure that the screen is powered off once every 2 hours for 1 hour each time.
During video aging at night, the power can be turned off if no one is on duty. This step helps to further eliminate potential bad spots.
4. Evaluation and repair Comprehensive evaluation:
After completing the aging stage, conduct a comprehensive evaluation of the LED display to determine whether there are other problems.
Professional repair: Solve the bad problems on site through repair, and arrange professionals to perform repairs and coating treatment.
Coating treatment can enhance the waterproof and moisture-proof performance of the screen and extend the service life.
Repeated testing: After the repair is completed, it should be repeatedly tested and aged again until the screen is stable.
5. Precautions Contact the manufacturer in time:
If the LED display is flooded, damp or severely damaged, please contact the manufacturer immediately for professional guidance and service.
Avoid wrong operation: Remember not to use a hot air blower to blow the water-soaked LED display screen to avoid aggravating the damage.
Conclusion
The remedial method for the LED display after water immersion requires careful and thoughtful handling of each step.
Through preliminary treatment, dehumidification and drying, aging treatment, evaluation and repair, and compliance with precautions, the normal operation of the LED display can be restored to the greatest extent and its service life can be extended.
