Q: What are the main tasks of daily maintenance of full-color LED displays?

answer:

Outdoor LED full color display has the advantages of good stability, low consumption, wide range of radiation, etc. It is the most suitable product for outdoor information transmission. However, in the long-term use process, outdoor LED full-color display will inevitably cause various failures due to pollution, looseness, vibration, heat, environmental temperature changes and other factors, affecting the normal use of LED full-color display, and even cause serious ACCIDENT. Therefore, regular maintenance of LED full-color displays is essential. What is the main reason for the daily maintenance of LED full-color displays?

First, the daily inspection: "Daily Inspection" is the daily inspection of the relevant display equipment, discover hidden dangers as soon as possible to safely handle. Generally include the following four aspects:

(1) Reinforcement inspection of internal component parts and steel frame structure: In the case of early warning of natural disasters such as weather deterioration, it is necessary to check the stability and safety of various components of the screen body, especially the various small components of the steel structure. If there is a problem, deal with it in time.

In addition, LED full-color display is a high-power consumption device, after a certain period of operation, due to multiple start and stop and run, in which the power supply part of the terminal due to cold and heat will cause loose, contact is not solid, form a virtual connection, serious Will heat up and even ignite the next plastic element. The signal terminals are also loosened due to changes in the temperature and the heat of the environment, resulting in poor contact due to moisture erosion, which in turn leads to equipment failure. Therefore, the connectors for the LED full-color display 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 lightning rods and grounding lines on a regular basis and test the facilities after thunderstorms. Replace them if damaged.

(3) Inspection of the control system of LED full-color display screen: Regularly check the reliability of the system to ensure its normal operation; for all lines and equipment of large screens, regular inspections shall be done to avoid accidents. .

(4) Screen body power supply system inspection: 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 ensured. Check the power supply line regularly to avoid line damage.

Second, the display screen body clean: LED full color display after working for some time, because of the influence of the external environment and affect the visual display of the display. At this time, we can visually inspect and check the full-color LED display in both bright and black screens. Including: whether the display surface is contaminated, the purpose is to remove the effect of surface dirt on the light emitting characteristics; whether there is damage crack on the surface of the LED full-color display screen; whether the communication distribution cable line is normal; for the equipment with high protection level, although due to the selection High reliability of 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 to clean the display surface.

LED full-color 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 full color display cleaning.

1, cleaning preparation need to pay attention to two points: before cleaning, need to pull out the power cord; cleaning fluid selection, cleaning fluid generally includes electrolyte, high-purity distilled water, antistatic liquid, etc., to choose good quality, in order to effectively clean Dust and other imprints on the LED full color display.

2. Cleaning and maintenance are divided into three steps:

The first step: vacuuming. First remove and remove dirt and dust from the surface of the LED full-color display mask.

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.

The above is the daily maintenance of LED full color display. The maintenance personnel must strictly follow the routine maintenance procedures and procedures, and actively implement it, so that LED full color display can spread more positive energy!
