Tips: LED display screen body water solution
Recently, there will always be news on the Internet or on TV that some areas have experienced heavy rains. Residents need to travel by boat. Extraordinary heavy rains not only cause a lot of inconvenience to people's travel, but also may cause some LED display manufacturers to warehouse. Water inflow causes water into the display screen. In response to this phenomenon, what measures should LED display manufacturers take to prevent water in the screen? Let's explain the solution of water in the LED display. method:
First, quickly blow the LED display screen body into the water with a fan or other tools;
Secondly, the screen body after being dried is powered on and aged. The specific steps are as follows:
(1) Adjust the brightness (full white) to 10%, and power on for 8-12 hours;
(2) Adjust the brightness (full white) to 30%, and power on for 12 hours;
(3) Adjust the brightness (full white) to 60%, and power on for 12-24 hours;
(4) Adjust the brightness (full white) to 80%, and power on for 12-24 hours;
(5) Adjust the brightness (full white) to *, and power on for 8-12 hours.
After completing the above steps, the LED display screen body will basically return to normal, but there are some points to note during the process:
1. When water is found in the warehouse or water in the LED display screen, it should be treated urgently without delay;
2.Organize personnel to blow dry the LED display screen body that is in the water;
3. Do not put the LED display screen body that has been flooded into the air box, this will easily suffocate the LED lights;
4. When the water enters the warehouse, it may be necessary for the air box to enter the water. All air boxes should be exposed to prevent the water from volatilizing into the LED display screen after the box is filled;
5. All the water-intake LED display screens are not processed in a timely manner, which may affect the stability of the screen body more or less. During the emergency treatment process, the phenomenon of continuous dead lights may occur after the screen body is powered on. Pay attention to observation at any time;
6. All the LED display screens that enter the water are in the flight case. For more than 72 hours, the screen is basically of no value for repair and needs to be handled with care.
In summary, in the face of the water ingress of the display screen, what is needed is the word "as soon as possible". Use the shortest effective method to deal with it. The longer the time, the greater the loss. When you encounter problems such as water in the warehouse, you must act immediately.
Gel timer Well-J01 is designed by IPC-TM-650 ,Gelation time refers to the time
required for liquid resin or adhesive to change from a flowing liquid into a solid gel at a
specified temperature. For thermosetting resins, it refers to the time required from
the addition of the catalyst to the formation of the gel.
