Like traditional electronic products, LED display screens not only need to pay attention to the method during use, but also need to maintain the display screen in order to make the large screen life of the LED display screen longer. On the one hand, the reason for the increase in the use of large-screen LED full-color displays is that major manufacturers have reduced the work materials of products in order to control production costs, which has led to the premature aging of a few accessories of some products. ; On the other hand, the reason is caused by the user's inappropriate usage habits. The latter situation is more common. The following editors will take you to take stock of several common methods for maintaining full-color LED displays.

1、 Maintenance of LED display

1. To carry out regular security inspections

The "monthly inspection system" is adopted for the general LED display security inspection, while the "weekly inspection system" is adopted for the large-scale LED electronic screen.

(1) Regular on-site inspection by technicians once a month to inspect and maintain the system.

(2) For outdoor display screens, damage caused by natural factors such as wind, rain, thunder and electricity is not covered by the warranty. The owner needs to apply for insurance to the insurance company, and the insurance company will pay for it.

(3) During the maintenance service period, the maintenance problem shall be solved within 8 hours for general failures, and no more than 24 hours for major accidents. If the maintenance needs to replace the module and other accessories, it should not exceed 24 hours. After the maintenance is completed, the service will ensure that the large screen does not have faults above the module level (such as module color cast, module black, one column is not bright, etc.), and it can be played normally.

(3) The protection of major events, the company's technical personnel guide and ensure the smooth development of on-site events.

2. Clean up the display

For display screens with lower protection levels, especially outdoor LED screens, dust in the air can easily enter the equipment through the ventilation holes, which will accelerate the wear and even damage of fans and other equipment. Dust may also fall on the surface of the internal control devices of the display screen, reducing the thermal conductivity and insulation performance. In wet weather, the dust absorbs moisture in the air and will cause a short circuit; it will also cause mildew on the PCB board and electronic components for a long time, resulting in equipment damage. The technical performance is degraded and malfunctions occur. Therefore, the cleaning of the led display screen may seem simple, but it is actually a very important step in the maintenance work.

3. Regularly tighten the LED display connectors

LED electronic screen belongs to high power consumption equipment. After running for a period of time, due to repeated start and stop and operation, the connection terminals of the power supply part will be loose due to cold and heat, the contact is not firm, and a virtual connection is formed. In severe cases, it will heat up, even Ignite the plastic components next to it. The signal terminals will also loosen due to changes in ambient temperature and heat, and moisture erosion will lead to poor contact, which will lead to equipment failure. Therefore, the connectors of the LED electronic screen must be regularly tightened. When adjusting the fasteners, the force should be even and appropriate to ensure firmness and effectiveness.

4. Regularly clean the surface of the display screen

LED electronic screen cleaning is a high-altitude operation, and a professional cleaning team is required. The cleaning operation adopts the method of high-altitude hanging rope (commonly known as spider man) or the use of hanging fence, equipped with professional cleaning equipment. Complete the cleaning of the display screen under the premise of and the mask.

There are two points to pay attention to when preparing for cleaning: 1. Before cleaning, you need to unplug the power cord. Second, the choice of cleaning liquid, cleaning liquid generally includes electrolyte, high-purity distilled water, antistatic liquid, etc., to choose good quality, in order to effectively clean the dust and other stains on the screen.

The specific cleaning and maintenance is divided into three steps:

Step 1: Vacuuming. Suction and sweep the dirt and dust on the surface of the display mask first.

Step 2: Wet cleaning. Be careful not to spray the lotion directly on the screen, but to spray a little cleaning liquid on the cleaning cloth, and then gently wipe in the same direction. You can also use the soft brush on the vacuum cleaner to brush the lamp mask to remove the dirt.

Step 3: Drying. Use a vacuum cleaner to absorb the water marks left by wet cleaning to ensure that the display mask is clean and dust-free.

2、LED display maintenance

Keep the humidity of the environment where the full-color LED display screen is used, and do not let anything with moisture properties enter your full-color LED display screen. Applying power to a large full-color display screen that contains humidity can cause corrosion of the full-color display components and cause permanent damage.

To avoid possible problems, we can choose passive protection and active protection, try to keep items that may cause damage to the full-color display screen away from the screen, and wipe the screen as gently as possible to avoid the possibility of injury. reduced to a minimum.

The large screen of the LED full-color display 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 is easy to get dirty, such as wind, sun, dust, etc. After a period of time, the screen must be dusty, which needs to be cleaned in time to wrap the surface with dust-proof soil for a long time to affect the viewing effect.

It is required that the power supply is stable and the grounding protection is good. Do not use it in harsh natural conditions, especially strong lightning weather.

Metal objects that are easy to conduct electricity such as water and iron powder are strictly prohibited in the screen. The large screen of the LED display 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.

The switching sequence of the LED electronic display: A: Turn on the control computer first to make it run normally, and then turn on the large screen of the LED display; B: Turn off the LED display first, and then turn off the computer.

When playing, do not stay in full white, full red, full green, full blue and other full bright screen for a long time, so as to avoid excessive current, excessive heating of the power cord, damage to the LED light, and affect the service life of the display. Do not disassemble or splicing the screen at will!

Liancheng Fa Xiaobian highly recommends that the large screen of the LED display has a rest time of more than 2 hours a day, and that the large screen of the LED screen is used at least once a week during the rainy season. Generally, the screen is turned on at least once a month for more than 2 hours.

The surface of the large screen of the led display can be wiped with alcohol, or dusted with a brush or a vacuum cleaner, and cannot be wiped directly with a damp cloth.

The large screen of the led display screen needs to be regularly checked for normal operation and whether the line is damaged. If it does not work, it should be replaced in time. If the line is damaged, it should be repaired or replaced in time. Non-professionals are not allowed to touch the internal circuit of the large screen of the led display to avoid electric shock or damage to the circuit; if there is a problem, please ask a professional to repair it.
