序章
Like any electronic device, LED表示画面 also require regular maintenance and care to ensure their long-term stable operation and extend their service life.
Ignoring maintenance may not only lead to the degradation of display performance, but may even cause failures and cause unnecessary losses. So, how to extend the service life of LED display screens through daily maintenance?
1. How long is the normal service life of LED display screens?
The service life of normal LED display screens is generally around 5 to 10 years, but how long it can actually be used depends on several factors.
First of all, it depends on the quality of LED lamp beads and electronic components. Good lamp beads and components are more reliable to use and break down slowly. Just like buying things, good quality will naturally last longer.
Let’s talk about the production process. If the workmanship is meticulous and the quality is strictly controlled during production, the display screen will be more stable and less likely to have problems. On the contrary, if the workmanship is rough, it may not last long.
The use environment is also very important. For example, if the temperature is too high or too low, it will make the display screen “uncomfortable” and affect its life. There is also humidity.
If it is too humid, it is easy for the components inside to get damp and cause problems. Dust and pollutants also make the display screen dirty, affect the display effect, and may block the heat dissipation area.
In addition, the frequency of use and maintenance should not be ignored. If you always turn it on or turn it on and off frequently, the display screen will get tired quickly. Regular maintenance, dust removal, inspection, and timely repair of problems will make the display screen last longer.
Therefore, if you want the LED display screen to last longer, you must choose good quality and good craftsmanship, pay attention to the environment, use it reasonably, and maintain it regularly. In this way, your display screen can accompany you longer.
2. Why is the daily maintenance of LED display screens so important?
1). The direct impact of daily maintenance on preventing failures, maintaining display effects, and extending service life
Daily maintenance is really like giving it a regular “physical examination” and “beauty” for LED display screens. Think about it, the LED display screen is composed of so many electronic components.
After working for a long time, it is inevitable that there will be some minor problems, such as loose connection wires and dust accumulating in the heat dissipation system. These seemingly insignificant problems, if not handled in time, may become a big trouble and cause the display screen to malfunction.
Moreover, daily maintenance can also keep the display effect of the display screen excellent. We all know that the purpose of watching LED display screens is to see clearly and brightly.
If the screen is full of dust, it will definitely look blurry, and the colors will not be bright. Therefore, regular cleaning and color calibration of the screen can keep the display effect in the best condition and make the audience comfortable.
Let’s talk about the service life. LED display screens are not used for one or two years and then thrown away. If they are well maintained, they can be used for five or six years or even longer.
Daily maintenance can reduce the load on the display screen and make the electronic components wear out more slowly so that the display screen can be used longer.
Moreover, regular inspections can also detect aging parts in time and replace them quickly to avoid the entire display screen being scrapped because of a small part.
2). Common problems that may be caused by neglecting maintenance
But if daily maintenance is neglected, it will be troublesome. The display screen may have various strange problems, such as flower screen, black screen, flickering, which are dazzling and cannot be used normally.
As the dust on the screen accumulates, the light transmittance and clarity will be greatly reduced, and the display effect will definitely not be good.
Also, neglecting maintenance may cause damage to the components of the display. If key components such as the power supply and drive circuit are damaged due to overheating or overvoltage, it will cost a lot of money to repair them.
In addition, dust and moisture may slip into the display, corrode electronic components, and make the components “retire” early.
What’s worse is that neglecting maintenance will shorten the service life of the display. A display that could have been used for several years may be scrapped in a few years due to lack of maintenance.
In this way, not only do you have to spend money to buy a new one, but you also have to pay extra for repairs and replacements, which is not cost-effective!
Finally, neglecting maintenance may also bring safety hazards. If the cooling system fails, the display may overheat or even cause a fire. If the power system is unstable, it may also cause electric shock, which is a great threat to people and equipment.
So, daily maintenance is really important for LED displays. Everyone must remember to clean, inspect, and maintain the display regularly to keep it in the best condition!
3. Specific maintenance measures for LED display screens
1). Cleaning and maintenance
1.1). Clean the screen surface regularly:
LED display screens are like our faces, which are exposed to the outside every day and are easily contaminated with dust, fingerprints, and other dirt. Therefore, we need to “wash” it regularly.
Use a soft dry cloth or a special LED display cleaning cloth to gently wipe it. When wiping, you have to be comprehensive and don’t forget the corners and gaps. Don’t use too much force.
Otherwise, it will be troublesome if the screen is scratched. If you encounter stains that are particularly difficult to wipe, you can use a little neutral detergent or a special LED display cleaner, but you still have to use a soft cloth to wipe it, and then wipe the detergent with a clean cloth after wiping, and wait until the screen is completely dry before using it.
1.2). Pay attention to the selection and use of detergents:
Be careful when choosing detergents; don’t use those that are acidic, alkaline, or corrosive, which may damage the LED lamp beads or the coating on the surface of the screen.
When buying detergents, you have to carefully read the ingredient instructions to ensure that they are neutral or especially used for LED displays. Before use, it is best to try it in an inconspicuous place on the screen to see if the cleaner has any effect on the screen.
Be careful when using it; don’t let the cleaner splash into the display or touch other sensitive places.
2). Inspection and tightening
2.1). Regularly check the frame, connecting wires, and interfaces of the display:
The frame of the display is like its skeleton, and you need to check it frequently to see if there are any deformations, looseness, or damage. Especially the joints and support points, you need to look carefully.
The connecting wires are like the blood vessels of the display, and you need to make sure they are tightly connected together without aging or damage. You can gently shake the connecting wires to see if they are firm.
The interface is like a bridge between the display and other devices, and you need to make sure they are in good contact without oxidation or damage.
The interface surface needs to be cleaned frequently, and the pins inside need to be carefully checked. If there are any damages, they need to be replaced quickly.
2.2). Tighten the loose screws:
There are many screws on the display, and they are like small nails, nailing the various components tightly together. You need to check these screws frequently to see if they are loose, and if they are loose, you need to tighten them with appropriate tools quickly.
Be careful when tightening, don’t use too much force to damage the screws or parts. Also, check whether the anti-loosening measures of the screws are effective, such as spring washers and locking nuts. If they are damaged or useless, they must be replaced immediately.
3). 電源と放熱管理
3.1). Ensure stable 電源:
LED display screens rely on electricity to light up, so the power supply must be stable. The voltage and frequency must be within the specified range. Don’t let them fluctuate and damage the display screen.
To be on the safe side, you can install a voltage stabilizer or UPS (uninterruptible power supply).
The voltage stabilizer can make the voltage stable, and the UPS can provide temporary power to the display screen when there is a problem with the power supply so that it can be shut down normally or switched to the backup power supply.
3.2). Check the cooling system regularly and clean the dust:
LED display screens generate a lot of heat when working, just like we sweat after exercise. If the heat dissipation is not good, the temperature will rise, affecting the performance and life of the display screen.
Therefore, you must check the cooling system frequently to see if the fan is running well and whether there is any abnormal sound or jamming. You also need to touch the heat sink to see if the temperature is normal.
If there is too much dust on the heat sink, you need to use a hair dryer or vacuum cleaner to blow or suck away the dust. If the fan is too dirty or does not rotate well, you need to remove it and wash or replace it.
4). Software update and calibration
4.2). Regularly update the control software and driver:
The control software and driver of the LED display are like its brain and nerves. They must be updated frequently to make them smarter and more useful. You can download the latest software and driver from the official website or manufacturer.
Before updating, it is best to back up the original software and driver in case there is a problem with the update, and you can restore it. When updating, you must follow the steps and don’t make mistakes.
4.2). Calibrate the color and brightness of the display:
The color and 輝度 of the LED display may change after a long time of use, just like our eyes will get tired after looking at things for a long time. Therefore, you need to calibrate the color and adjust the brightness of the display regularly.
You can use professional color calibration instruments and software to do it. When calibrating, the display parameters, such as color temperature, color saturation, and brightness, must be adjusted based on the measurement results.
The frequency of calibration depends on the use environment and needs. Displays that are frequently used or in places with high environmental requirements must be calibrated once a month.
Displays that are rarely used or in places with low environmental requirements can be calibrated at a later time. In this way, the color and brightness of the display can always be kept in the best state, and we can also look comfortable.
4. Preventive maintenance plan for LED display
1). Develop a maintenance schedule
In order to ensure that the LED display can operate stably for a long time and extend its service life as much as possible, you have to develop a detailed and systematic maintenance schedule.
