The LED display screen is like a traditional electronic product. In the process of use, not only the method needs to be paid attention, but also the display screen needs to be maintained, so that the LED display can be used for a longer period of time.
- Considerations for turning the display on and off
1.1 Turn on the LED Display Turn on the control computer to make it run normally, then turn on the LED display screen.
1.2 Turn off the LED Display: First turn off the LED screen power, turn off the control software, and then turn off the computer properly.( If you do not turn off the power of the display before turning off the computer, it will cause the screen to appear highly bright lines, which will burn the lamp, causing serious consequences.)
1.3 The usage time should not be less than 5 minutes each time the display is turned on.
1.4 Avoid opening the screen in the full white screen state, because at this time it is the maximum power state, which has the largest inrush current to the entire power distribution system.
- Power supply precautions
2.1 Should choose high quality and reliable power supply. The LED module is DC +5V power supply (operating voltage: 4.2~5.2V), it is forbidden to use AC power supply; the positive and negative terminals of the power supply terminal are strictly prohibited to be reversed (Note: once connected, it will burn out the product and even cause serious fire);
2.2 Power supply voltage for LED display: Please contact us when placing an order, we will adjust for your country or region.
2.3 Reliable grounding should be performed, and the ground and the neutral should be reliably isolated to avoid using the same cable with high-power equipment.
2.4 If abnormalities such as short circuit, tripping, burning line, or smoke are found, the power should not be tested repeatedly. You should immediately find the problem.
2.5 The large screen must be powered step by step because the maximum power state of the entire screen will impact the entire power distribution system;
2.6 The large screen must be powered step by step because the maximum power state of the entire screen will impact the entire power distribution system;
2.7 The LED display does not allow the highest brightness of white to be played for more than half an hour, so as to avoid excessive current, the power line is hot, and the LED light is damaged, which affects the life of the display.
2.8 During the use of the LED display, it is forbidden to turn the power on and off frequently.
- Cleaning precautions
3.1 Regular cleaning and maintenance: LED display is used for a long time, and more dust and rain washes will accumulate on the screen. This requires regular and timely cleaning to prevent the viewing effect from affecting;
3.2 If you clean the surface of the module, use a soft brush to gently wipe it. It is forbidden to use any liquid substance to clean the surface of the indoor LED module, otherwise the LED lamp bead may be damaged;
3.3 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.
- Storage requirements
4.1 Temperature: ambient temperature -40 ° C ≤ t ≤ 60 ° C, after the package is opened, LED products must be stored in the temperature <30 ° C and humidity <60% environment;
4.2 According to the environment of the LED display and the control part, avoid insect damage, and if necessary, place an anthelmintic
4.3 LED display is not recommended for long-term idle. In high humidity environment, if the screen is not used for 3 days, it needs to be warmed up every time the screen is illuminated.
The large LED screen needs to be checked regularly for proper operation, and the damaged cable should be repaired or replaced in time. If the conditions permit, the related equipment such as the main control computer should be placed in an air-conditioned, dust-free room to ensure that the computer is ventilated and stable. The internal wiring of the screen is forbidden to touch by non-professionals to avoid electric shock or damage to the line. If there is a problem, you should ask our professional engineer for inspection.
