How to maintain outdoor LED advertising screen in summer
There are more and more applications of LED displays in the outdoor field, and the industries involved are becoming more and more extensive, especially in outdoor advertising. Many advertising media have used the card of LED displays to expand their presence in the advertising market. share and enhance the influence of the company’s brand.
In actual operation, the life of the LED full-color display directly affects the return on investment cycle of the enterprise. In order to shorten the return on investment period and improve gross profit, it is necessary to understand and master the following seven common sense of LED display maintenance.
1. Switch sequence. When turning on the display, turn on the computer first, and then turn on the screen. When turning off the display screen: turn off the screen first, then turn off the computer (Turn off the computer first without turning off the display screen, which will cause bright spots on the screen body, burn the lamps, and have serious consequences.) The interval between switching the screen should be greater than 5 minutes. After the computer enters the engineering control software, the screen can be powered on.
2. To avoid possible problems, we can choose passive protection and active protection, try to keep items that may cause damage to the outdoor LED large screen away from the screen, and wipe the screen as gently as possible to prevent damage. possibility is minimized.
3. The outdoor LED advertising screen has the closest relationship with our users, and it is also very necessary to do a good job of cleaning and maintenance. Exposure to the outdoor environment for a long time, such as wind, sun, dust, etc., is easy to get dirty. After a period of time, the screen must be covered with dust. This needs to be cleaned in time to wrap the surface with dust-proof soil for a long time to affect the viewing effect.
Fourth, the power switch of the display screen often trips, and the screen body of the LED unit board should be checked in time or the power switch should be replaced. The power supply of the display screen is very important. Because the power supply is under different temperature conditions, its working stability, output voltage value and load capacity will also be different. Because it is responsible for logistics support, its support ability directly affects. screen quality.
5. Metal objects that are easy to conduct electricity such as water and iron powder are strictly prohibited in the screen. The outdoor LED advertising 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 for various reasons, please turn off the power immediately and contact the maintenance personnel until the display panel in the screen is dry before use.
6. It is recommended that the outdoor LED advertising screen rest for more than 2 hours a day. With the extension of the boot time and the increase of the external temperature, the thermal drift of the components will also increase, resulting in poor image quality. Use the outdoor LED display at least once a week during the rainy season. Generally, the screen is turned on at least once a month, and it is lit for more than 2 hours. This is done to remove moisture and prevent the lamp beads from getting wet and dead, especially for SMD surface mount displays.
7. When playing, do not stay in full white, full red, full green, full blue, etc. for a long time, so as not to cause excessive current, excessive heat of the power cord, damage to the LED lights, and affect the service life of the display. Do not disassemble or splicing the scree
