To improve the stability of the work is mainly to work hard on the maintenance. The power supply is required to be stable, and the grounding protection is good. Do not use it under harsh natural conditions, especially during strong lightning. To avoid problems that may be encountered, we can choose passive protection and active protection, try to keep the items that may cause damage to the full-color display screen away from the screen, and wipe the screen as gently as possible to remove the possibility of injury. Minimize. Turn off the LED display before turning off the computer.
Keep the full-color LED display on the large screen using the humidity of the environment, do not let anything with moisture properties enter your full-color LED display screen. Powering up the large screen of a full-color display with humidity can cause corrosion of the full-color display components, which can cause permanent damage.
If water enters for various reasons, immediately turn off the power and call the service personnel until the display panel in the display panel is dry before use.
LED display switching sequence:
A: Turn on the control computer to make it run normally before turning on the LED display screen.
B: It is recommended that the LED display screen has a daily rest time of more than 2 hours per day. In the rainy season, the LED screen is used at least once a week.
Generally, the screen is turned on at least once a month, and it is lit for more than 2 hours.
Do not stay in full white, full red, all green, all blue, etc. for a long time during playback, so as to avoid excessive current, excessive heating of the power cable, damage to the LED light, and affect the service life of the display.
Do not disassemble or splicing the screen at will! The LED full-color display screen has the closest relationship with our users. It is also necessary to do the cleaning and maintenance work.
The outdoor LED display is exposed to the outdoor environment for a long time. The wind, the sun, the dust and the like are easy to be dirty. After a period of time, the screen is definitely a piece of dust. This requires timely cleaning to protect the viewing effect by the dust-proof soil for a long time.
The large screen surface of the LED display can be wiped with alcohol, or dusted with a brush or a vacuum cleaner. It cannot be wiped directly with a damp cloth.
