LED display use precautions and routine maintenance of small knowledge notes
In the use of the process not only need to pay attention to the method, but also need to maintain the display maintenance, in order to make the LED display large screen life longer. Now we come together to understand:
01 switch screen precautions
1, open the screen: first open the control computer so that it can run normally and then open the LED display screen; 2, close the screen: first turn off the LED display screen; 2, close the screen: first turn off the LED display screen.
2, off the screen: first turn off the LED screen body power, turn off the control software, and then correctly shut down the computer; (first off the computer does not shut down the display, will cause the screen to appear high brightness, burned lamps, the consequences are serious)
3, switch the screen interval should be greater than 5 minutes.
4, avoid opening the screen in the full white screen state, because this time for the maximum power state, the impact of its current on the entire power distribution system is the largest.
02 Power supply considerations
1, LED module for DC +5V power supply (operating voltage: 4.2 ~ 5.2V), prohibit the use of AC power supply; power terminals positive and negative poles are strictly prohibited to reverse (Note: Once reversed will burn the product or even cause a serious fire);;
2, LED display power supply voltage: 220V ± 10% frequency: 50HZ ± 5%.
3, safe and reliable earth contact, ground and zero line isolation is reliable, access to the power supply away from high-power equipment.
4, such as the discovery of short-circuit, trip, burn line, smoke and other abnormalities, should not be repeated power test, should promptly find the problem.
5, to maintain a stable power supply, and good grounding protection to avoid lightning strikes, in poor natural conditions, especially strong lightning weather do not use.
6, must be step by step to the big screen power supply power supply, because the whole screen maximum power state will have an impact on the entire power distribution system.
7, LED display is not allowed to play the highest brightness all-white screen for more than half an hour, so as not to cause excessive current, power line heating, LED lamp damage, affecting the service life of the display, it is recommended to play the main dynamic video;;
8, LED display products in the process of use, not continuous power on and off, the two operations should be separated by at least 1 minute.
9, LED display screen internal lines, non-professionals are prohibited from touching, in order to avoid electric shock, or cause line damage.
03 Cleaning Precautions
1, regular cleaning and maintenance: LED display used for a long time, the screen will accumulate more dust and rain scouring traces, which need to be regular, timely cleaning to prevent the impact of viewing effect;.
2, such as cleaning the module surface, please use a soft brush, gently brush. Prohibit the use of any liquid substances to clean the surface of the LED module, otherwise the LED lamp beads may be damaged.
3, the correct wipe: LED display screen surface can be wiped with alcohol, or use a brush, vacuum cleaner for dust removal, not directly with a wet cloth.
04 Moisture-proof and storage requirements
1, storage temperature requirements: ambient temperature -40 ℃ ≤ t ≤ 60 ℃, after the package is opened, LED products must be stored in the temperature <30 ℃ and humidity <60% environment;;.
2、According to the display body, the control part of the environment in which the situation, to avoid insect bites, if necessary, should be placed to prevent rodenticide;
3, LED display can not be closed for a long time, in a high humidity environment, if the screen body is not used for more than 3 days, each time you light up the screen body needs to be used to preheat the lighting mode: 30% -50% of the brightness of the first preheating 4-8 hours, and then adjusted to the normal brightness (80% -100%) to light up the screen body, so that the moisture out of the use of no abnormality; if the screen body more than 7 days unused, each time you light up the screen body needs to use preheating Screen need to be used to preheat the lighting mode: 30% -50% of the brightness of the first preheating for more than 12 hours, and then adjusted to the normal brightness (80% -100%) to light up the screen, so that the moisture will be excluded, so that there is no abnormality in the use of the screen.
LED large screen need to regularly check whether the normal work, line damage should be repaired or replaced in a timely manner. The main control computer and other related equipment should be placed in an air-conditioned, dusty room to ensure that the computer ventilation and heat dissipation and stable work. The internal lines of the screen, non-professionals are prohibited to touch, so as not to electrocute, or cause damage to the line, if there is a problem, you should ask a professional to overhaul.
