Large LED display screens are the same as traditional electronic products. Not only do you need to pay attention to the method during use, but also need to maintain the display screen in order to make the life of the large LED display screen longer. Here, Changcai Electronics will analyze several ways to maintain the large screen of LED full-color display for everyone. 1. Keep the humidity of the environment where the full-color LED display is used, and do not let anything with moisture into the full-color LED display. Powering on a full-color display that contains humidity will cause corrosion of the components of the full-color display, resulting in permanent damage. 2. 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 when cleaning the screen, wipe it as gently as possible to avoid the damage. The possibility is minimized. 3. The large screen of the LED full-color display has the closest relationship with our users, and it is very necessary to do a good job in cleaning and maintenance. Long-term exposure to outdoor environments such as wind, sun, dust, etc. will easily become dirty. After a period of time, the screen will definitely be dusty. This needs to be cleaned in time to prevent the dust from wrapping the surface for a long time to affect the viewing effect. 4. It is required that the power supply is stable and the grounding protection is good. Do not use it under severe natural conditions, especially strong thunder and lightning. 5. It is strictly forbidden to enter water, iron powder and other easily conductive metal objects in the screen. The large LED display screen should be placed in a low-dust environment as much as possible. Large dust will affect the display effect, and too much dust will cause damage to the circuit. If water enters due to various reasons, please cut off the power immediately and contact the maintenance personnel until the display panel in the screen is dry before use. 6. The switch sequence of the LED display: A: First turn on the control computer to make it run normally, then turn on the large LED display; B: Turn off the LED display first, then turn off the computer. 7. Don't stay in full white, full red, full green, full blue, etc. for a long time during playback, so as to avoid excessive current, excessive heating of the power cord, damage to the LED light, and affect the service life of the display. Do not disassemble or splice the screen at will! 8. It is recommended that the large LED screen has a rest time of more than 2 hours a day, and the large LED screen should be used at least once a week during the rainy season. Generally, turn on the screen at least once a month and light it for more than 2 hours. 9. The surface of the large screen of the LED display can be wiped with alcohol, or use a brush or vacuum cleaner to remove dust. It cannot be wiped directly with a damp cloth. 10. The large LED display screen needs to be checked regularly for normal operation and whether the circuit is damaged. If it does not work, it should be replaced in time, and the circuit should be repaired or replaced in time if it is damaged. Non-professionals are forbidden to touch the internal wiring of the LED display to avoid electric shock or damage to the wiring; if there is a problem, please professionally repair it.
