  With the advancement of technology, LED electronic display screens have flourished in various fields, becoming a crucial medium for information dissemination. Whether for commercial advertising or public information dissemination, LED display screens play an indispensable role. However, to ensure the long-term stable operation of these screens, routine maintenance and precautions are essential. In this digital age, LED display screens have become common devices in our daily lives. But do you know how to properly maintain them to extend their lifespan? This article will provide you with detailed information on the common maintenance methods and precautions for LED electronic display screens, allowing your information windows to shine brightly for years to come! Environmental Considerations: Operating temperature range: -20℃≤t≤50℃, operating humidity range: 10% to 90% RH. Avoid usage or storage in high temperature, high humidity, or high acidity/alkalinity/salinity environments. Keep away from flammable materials, gases, and dust. Avoid strong collisions during transportation and prevent sharp objects from impacting the screen. Do not use the screen for extended periods in high ambient temperatures or poor heat dissipation conditions. Exceeding the specified humidity can cause component corrosion and even permanent damage. Do not allow water or iron powder, which conducts electricity easily, to enter the screen. LED displays should be placed in low-dust environments as excessive dust can affect display quality and damage circuits. If water enters for any reason, immediately power off until all components inside the screen are dry before use. Avoid placing aquariums, plants, or flowers near the screen, as they create a damp environment.     Power On/Off Considerations: Power On: Start the control computer first to ensure normal operation before turning on the LED display screen. Power Off: Turn off the LED screen power first, then close the control software, and finally shut down the computer correctly. (Turning off the computer before the display screen may cause bright spots on the screen and serious consequences). The interval between power on/off cycles should be greater than 5 minutes. Avoid powering on with a fully white screen, as this is the highest power state and can cause maximum current impact on the entire distribution system. Power Supply Considerations: LED modules are powered by direct current +5V (working voltage: 4.2-5.2V) and AC power is strictly prohibited. Reverse connection of the positive and negative terminals of the power terminal is strictly prohibited (note: reverse connection will burn the product or even cause a serious fire). The power supply voltage for LED display screens is 220V±10%, frequency: 50HZ±5%. Ensure reliable grounding and isolate the ground wire from the neutral wire. Keep the power supply away from high-power electrical equipment. If anomalies such as short circuits, tripping, wire burning, or smoke are detected, do not repeatedly test the power supply. Troubleshoot the problem promptly. Maintain stable power supply and implement grounding protection to avoid lightning strikes. Do not use the screen under harsh natural conditions, especially during severe thunderstorms. The power supply must be provided step by step to the large screen, as the maximum power state of the entire screen will have an impact on the entire distribution system. LED display screens are not allowed to play full white screens at maximum brightness for more than half an hour to prevent excessive current, overheating of the power line, LED damage, and affecting the lifespan of the display screen. It is recommended to mainly play dynamic videos. Do not switch the LED display screen's power on and off continuously. There should be at least a 1-minute interval between the two operations. Non-professionals are prohibited from touching the internal circuits of the LED display screen to avoid electric shock or damage to the circuits. If a problem occurs, seek professional assistance for repairs. Cleaning Considerations: Regular cleaning and maintenance are necessary as LED full-color display screens are often exposed to outdoor elements such as wind, sun, rain, and indoor dust accumulation. When cleaning the module surface, use a soft brush to gently wipe. Do not use any liquid substances to clean the surface, as this may damage the LED chips. Alcohol can be used to wipe the surface of the LED display screen, or a brush or vacuum cleaner can be used for dust removal. Do not wipe directly with a wet cloth.   Moisture-proof and Storage Requirements: Storage temperature requirements: ambient temperature -40℃≤t≤60℃. After opening the packaging, LED products should be stored in an environment with temperature <30℃ and humidity <60%. Prevent insect bites and, if necessary, place rodent repellents according to the environment of the display screen and control part. LED display screens should not be turned off for long periods. If the screen is unused for more than 3 days in a high-humidity environment, each time it is turned on, use a preheating method: preheat at 30%-50% brightness for 4-8 hours before adjusting to normal brightness (80%-100%) to remove moisture and ensure normal operation. If the screen is unused for more than 7 days, preheat at 30%-50% brightness for more than 12 hours before adjusting to normal brightness (80%-100%). Notes: Regular maintenance of LED display screens is crucial for extending their lifespan and ensuring normal operation. Check regularly for normal operation and repair or replace damaged circuits promptly. Control computers and related equipment should be placed in air-conditioned, low-dust rooms to ensure ventilation and stable operation. Non-professionals are prohibited from touching the internal circuits of the screen to avoid electric shock or circuit damage. Seek professional assistance for any issues that may arise.
