Now, most of the outdoor LED displays on the market are after-sales maintenance. It's crazy to remove the back cover every time and toss all kinds of circuit maintenance work inside. In fact, the maintenance of outdoor LED display screen is not as difficult as expected. As long as we can figure out a few steps and do a good job in daily maintenance, the maintenance of outdoor LED display screen will be much more smooth.

Outdoor, the main factors affecting the LED display screen are weather, environment, air humidity and so on. When installing an outdoor LED display screen, we should pay special attention to wind resistance, earthquake resistance, bearing capacity, sun protection and rain protection, so that it can survive and operate better outdoors. The daily maintenance of outdoor LED displays is very important. Here is how to maintain them.

  • The outdoor LED display shall be kept dry. At the same time, the display screen should be placed in a low dust environment as far as possible. Large dust will affect the display effect, and too much dust will damage the circuit. In case of water inflow for various reasons, please cut off the power immediately and contact the maintenance personnel of LED electronic display screen until the display panel in the screen body is dry. Power on the outdoor LED display screen containing humidity will cause corrosion of parts and components, resulting in permanent damage. Rainproof measures shall be taken.
  • Choose passive protection and active protection. Try to keep the objects that may cause damage to the outdoor LED large screen away from the screen. When cleaning the screen, wipe it gently as much as possible to minimize the possibility of damage.
  • If the display screen is exposed to the wind, sun and dust for a long time, it is easy to be dirty. After a period of time, there must be a piece of dust on the screen, which needs to be cleaned in time to wrap the surface with dust-proof soil for a long time, which will affect the viewing effect. It is necessary to do a good job of cleaning and maintenance. The power supply shall be stable and the grounding protection shall be good. It shall not be used in bad environments, especially in strong lightning weather.
  • Switching sequence of outdoor LED display screen: first, turn on the control computer to make it operate normally, and then turn on the outdoor LED display screen. Second: turn off the outdoor LED display first, and then turn off the computer.
  • The outdoor LED display needs to rest for more than 2 hours every day. In the rainy season, the outdoor LED large display should be used at least once a week. Generally, the screen is turned on at least 3 times a month.
  • Regularly check whether the outdoor LED display screen works normally and whether the line is damaged. Replace or repair the damaged line in time to keep the display screen working normally.

With the combination of diode and semiconductor, its production material and manufacturing process are gradually upgraded, breaking through the limitations of the original brightness and color, and a large number of blue diodes and pure green light-emitting diodes are used to improve the display brightness. Thus, the advantages of the LED display screens in outdoor environments are improved, which can adapt to different display requirements and improve the effective value of LED in different environments. The performance evaluation of outdoor LED display screen must be the result of comprehensive consideration because its relevant performance indicators are closely related, and the indicators such as brightness, viewing angle and resolution affect each other. At present, in the high-density and full-color indoor display screen, surface-mounted LED devices are used to improve the viewing angle and brightness performance of the display screen.
