The outdoor LED display has the advantages of good stability, low consumption, wide radiation range, etc. It is the most suitable product for outdoor information transmission. However, in the long-term use of the process, outdoor LED displays will inevitably cause various failures due to pollution, looseness, vibration, heat, environmental temperature changes and other factors, affect the normal use of LED displays, and even cause serious accidents. Therefore, regular maintenance of LED display screens is essential. So what is the main task of daily maintenance of LED display?
First, daily inspection
"Daily Inspection" is to conduct routine inspections and inspections of relevant display equipment and discover hidden dangers as soon as possible to safely handle them. Generally include the following four aspects:
(1) Reinforcement inspection of various internal components and steel frame structures: It is necessary to check the stability and safety of various components of the screen body during early warning of natural disasters such as weather deterioration, especially for the various small components of steel structures. Have problems and deal with them in time.
In addition, the LED display panel is a high-power-consumption device. After a relatively long period of operation, due to multiple start-stops and operations, the terminals of the power supply part are loosened due to cold and heat, and the contacts are not solid, forming a false connection. And even ignite the plastic element next to it. The signal terminals are also loosened due to the change of the ambient temperature, hot and cold, and the moisture erosion causes poor contact, which in turn leads to equipment failure. Therefore, the connector of the LED display screen must be tightened regularly. When adjusting the fasteners, the force should be applied evenly and properly to ensure solid and effective.
(2) Inspection of lightning protection facilities: Check the lightning rods and grounding lines regularly, and test the facilities after thunderstorms. Replace them if damaged.
(3) Inspection of the LED large-screen control system: Regularly check the reliability of the system to ensure its normal operation. Regular inspections are also required for all lines and equipment of large screens to avoid unexpected situations.
(4) Inspection of the screen power supply system: First of all, check whether the line connection in the distribution box is rusted or loose. For safety, the grounding of the electrical box must be guaranteed. Check the power supply line regularly to avoid line damage.
Second, the display screen body clean
After working for a period of time, the LED screen will influence the visual viewing effect of the display due to the influence of the external environment. At this time, we can conduct visual inspection and inspection of the LED display under both light and black screen conditions. Including: whether the display surface is contaminated, the purpose is to remove the effect of surface dirt on the light emitting characteristics; whether the display surface has damage cracks; communication distribution cable lines are normal; for the equipment of high protection level, although due to the high reliability The components and connectors, but resulting in hermeticity as a key factor, therefore, to regularly check the integrity of the seal; for outdoor screen steel structure to check the surface paint and rust; for the outdoor screen surface is particularly serious pollution, but also Clean the display surface.
LED display cleaning is a high-altitude operation and requires a professional cleaning team. The cleaning operation adopts a high-altitude hanging rope method (commonly known as the spider man) or hang blue, and configures professional cleaning equipment. The cleaning personnel selects different cleaning agents according to different dirt on the screen to perform targeted cleaning, thereby ensuring that the LED tube is not damaged. And under the premise of the mask to complete the LED display cleaning.
There are two things to note when preparing for cleaning:
First, before cleaning, you need to pull out the power cord.
Second, the choice of cleaning fluid, cleaning fluid generally includes electrolyte, high-purity distilled water, antistatic fluid, etc., to choose good quality, in order to effectively clean the LED screen dust and other imprints.
Cleaning and maintenance are divided into three steps:
The first step: vacuuming. First remove and remove the dirt and dust from the display mask surface.
The second step: wet wash. Be careful not to spray the lotion directly on the screen. Instead, spray a small amount of cleaning solution on the cleaning cloth and gently wipe it in the same direction. It is also possible to scrub the lamp mask with a soft brush on the vacuum cleaner to clean the dirt.
The third step: drying. Use a vacuum cleaner to dry the water marks left after the wet wash to ensure that the display mask is clean and dust-free.
