Outdoor LED Display Maintenance Knowledge
As the new outdoor advertising media advertising, outdoor LED display is widely used in finance, taxation, industry and commerce, telecommunications, sports, advertising, business, transportation, education systems, securities markets Induction, creative display and so on. The generally occupied area of outdoor LED display screen is relatively large, usually in tens of square meters to several hundred square meters or even larger, featuring high brightness, wide viewing angle, wind-proof, waterproof and other functions. Since we spent a lot of effort to install the LED screen, of course, we hope it can be used longer with much clearer effects. So the necessary knowledge for the maintenance of outdoor LED display is required.
1. Outdoor LED large screen must maintain a dry environment for use. Screen body is strictly prohibited with water, iron and other metal materials which are easy to conduct electricity. Powering on the outdoor LED large screen with humidity will lead to corrosion of parts and components, resulting in permanent damage. Rainproof measures should be adopted.
2. To avoid possible problems, we can choose to passive protection and active protection. Taking away from the LED screen as far as possible for items that could cause damages, and when cleaning the screen, it is best to gently wipe in order to make the damaged possibility to a minimum.
3. Outdoor LED display has the closest relationship in our users. Good cleaning and maintenance work is also very necessary. Exposing for a long time to outdoor wind, sun, dust and others, which is easy to be dirty. The screen is definitely full of dust for a period of time, which requires timely cleaning to prevent it from causing impact for the watching effects.
4. Switch sequence of outdoor LED display: turning on: turn on the control computer first to enable it to normal operation and then power on the LED display. Turning off: switch off the screen first, and then turn off the computer.
5. Stable power supply and good grounding protection, do not use in the harsh natural conditions, especially strong lightning weather.
6. Do not play a long time in full white, all red, all green, blue and other full-brightness screen, so as to avoid excessive current, too much heat on power cables, LED lamp damage, affecting the lifespan of the display. Do not disassemble, splice the screen body.
7. To regularly check if the outdoor LED display works properly, the cable connection is with damage. If needed, timely replacement or repair damaged cables, to maintain the normal work of the LED screen.
8. Outdoor LED large screen's master computer and other related equipment should be placed in a space with air conditioning and less dust, to ensure of good ventilation, cooling and stability.
What are the precautions of indoor LED display?
First, notice for indoor LED display switch: 1. switch sequence: when turning on the screen: turn on the computer first and then the LED screen; when switching off screen: turn off the screen first and then the computer. Turning off the computer without switching off the screen first, the screen will cause bright spots. It is easy to burn the lamp. The consequences are serious.
2. When switching on or off the LED display, the interval time is greater than 1 minute; By instantly turning on and turning off immediately, the impact of the display is great, which is easy to cause damage on the screen body because of the impact of large power voltage.
Second, ambient temperature:
When the ambient temperature is too high or the heat dissipation condition is not good, be careful not to turn on the screen for a long time; the screen should be installed in the temperature range of -10 ℃ ~ 40 ℃ environment; installing temperature control equipment when beyond that temperature range. Do not install the LED display near any heating source. High ambient temperature or poor heat dissipation can easily reduce the lifespan of the LED screen.
Third, the environmental humidity:
When installing the LED screen, the relative humidity should be in the range of 30% -70%, when the indoor environment humidity is less than 30%, which can easily produce static electricity; when the indoor environment humidity is higher than 70%, which can easily cause dampness for the LED lamps.
Fourth, environment with corrosive gas:
Do not install the display in an environment with corrosive gas, such as a chemical or chemical warehouse, near an indoor swimming pool or in the vicinity of the indoor swimming pool (recommend using outdoor SMD LED display if necessary).
Fifth, environment with electromagnetic radiation:
Please do not install the screen in the electromagnetic radiation. When the radio frequency radiation is more than the field strength of 5V/m interference in the environment, isolation must be done if necessary.
Sixth, environment with strong light:
Please do not install the LED display in the direction of strong light, because bright light will affect the display effects of the screen, and the brightness of the display requirements are higher.
Seventh, to maintain power stability:
Maintaining a stable power supply if necessary. Install the surge tank in the distribution box, and do a good grounding protection against lightning. In the strong lightning weather and other harsh natural conditions, do not use the display.
Eighth, the LED screen body is strictly prohibited with water, metal dust and other conductive substances.
LED display should be placed in the environment with low dust, otherwise it will affect the display, while the circuit will cause damage. If water gets in, please power off immediately and contact the maintenance personnel. Do not use until the screen body unit board is dry.
Ninth, control the screen display:
It is recommended not to make the display screen for a long time in full white, full red, all green, all blue and other full-screen, as it will affect the display screen's lifespan. Do not disassemble or splice the screen body.
Tenth, control the use of time:
Recommended that the LED display screen should stop at least 2 hours per day for rest; generally start the screen at least twice a week or more (especially the rainy season; need to start once a day normally), and the running time should be 2 hours or more.
Eleventh, storage of LED screen modules:
Do not unpack the LED unit module boards; place them in a dry place before using. Ensure that they are stored in an environment where the temperature is not higher than 30 degrees Celsius and the humidity is not higher than 60%.
Twelve, please be sure to place a thermometer and hygrometer in the warehouse at any time to monitor the temperature and humidity.
Thirteen, when installing the display screen, to wear some anti-static equipment.
