Has your pantalla LED not been maintained for a long time? Don’t underestimate cleaning and maintenance; they are more important to the display screen than “maintenance products.”
If it is neglected for a long time, the display screen will go on strike! What will happen? Let’s find out.

Consequence 1: Accelerated brightness decay of LED display screen
If the LED display screen is not maintained and cleaned for a long time, it will be troublesome, and the brillo of the display screen will decay faster.
Under normal circumstances, the brightness of the LED display screen will gradually dim because the semiconductor materials inside will age over time, and the luminous efficiency will decrease.
Moreover, if the surface of the display screen is full of dust and stains, this dirt will block the light, making the display screen look darker, and the brightness will decrease faster.
Take some actual examples; for example, some displays that are not cleaned well have a particularly severe brightness drop.
For example, the LED poster screen of a cinema was pitifully low in brightness, and the picture was blurry because it was not managed before.
Later, after regular cleaning and maintenance, the brightness was significantly improved, and the picture became clear and bright.
In terms of advertising, if the advertising screen is not bright enough, it is difficult to attract people’s attention, and the advertising effect is greatly reduced.
Like the LED advertising screen on the commercial street, after cleaning and maintenance, the brightness has been restored a lot, the color is more vivid, and it can attract customers again.
In terms of traffic instructions, if the display screen is not bright enough, the driver may not be able to see the instructions clearly in strong light or bad weather, which is easy to cause danger.
Therefore, it is really important to clean and maintain the LED display screen regularly, which can not only extend the service life but also ensure the display effect and avoid various problems.
Consequence 2: The color deviation of the LED display screen increases
If the LED display screen is not cleaned and maintained for a long time, the color deviation will be large.
We all know that the LED display screen can change into various colors, relying on the three colors of red, green, and blue lamp beads.
These three colors of lamp beads are combined in different proportions to create colorful pictures.
Just like a palette, when the red and green lamp beads are lit together, yellow will appear; when all three lamp beads are lit, white will appear.
Cleaning is very important to maintain color accuracy. If the display screen is full of dust and stains, this dirt will absorb or reflect part of the light, changing the purity and saturation of the color.
It’s like a layer of dust on a painting, and the color will definitely not be bright.
If it is not cleaned for a long time, the color deviation will be particularly obvious. For example, white will be yellowish because the dust absorbs part of the blue light, and the blue component in the white light is less.
Red will be darker, and the dust blocks the normal emission of red light, so the red will not appear bright. This deviation is clearer with pictures or examples.
Like an originally bright landscape picture, on an uncleaned display screen, the blue sky becomes gray, the green grass becomes yellowish, and the picture is not vivid at all.
When playing movies and TV, the color deviation will destroy the atmosphere of the picture.
For example, in a romantic love movie, the originally warm pink picture becomes dim, and the audience’s sense of immersion is gone.
In art exhibitions, color accuracy is extremely important. If the color deviation of the display screen is large, the original appearance of the artwork cannot be restored.
The audience cannot appreciate the details and color levels, and their understanding and appreciation of the work will also be affected.
For example, the LED display screen in a shopping mall in Guangzhou had a serious color deviation because it was not taken care of before.
When playing advertisements, the color of the screen changed, and customers were uncomfortable watching it.
Later, the mall regularly cleaned and maintained it, and the color deviation was significantly improved, and the picture became bright and vivid again.
Therefore, regular cleaning of the LED display screen can not only extend the service life but also ensure the accuracy of the color and improve the visual effect.
Consequence 3: The heat dissipation performance of the LED display screen is reduced
If the LED display screen is not maintained and cleaned for a long time, the heat dissipation performance of the display screen will be greatly reduced.
When the LED display screen is working, the internal electronic components will generate heat, which is a normal phenomenon.
Just like we sweat when we work more, the display screen will also “heat up” after working for a long time. If this heat is not dissipated in time, the internal temperature of the display screen will rise, affecting normal operation.
Generally speaking, the display screen has a good heat dissipation system, such as heat sinks and heat dissipation channels, which are like the “air conditioner” of the display screen, helping to dissipate excess heat.
However, if the display screen is not cleaned for a long time, dust will accumulate on the heat dissipation channel and heat sink, blocking the heat dissipation channel, and the heat sink will also lose the heat dissipation effect.
This is like the “air conditioner” is blocked; the heat cannot be dissipated, and the temperature inside the display will get higher and higher.
Once the temperature rises, problems arise. The electronic components inside the display cannot withstand high temperatures, and high temperatures will accelerate the aging of the components, and fires may occur due to the increase in internal temperature.
Consequence 4: More pixel failures on LED displays
If the LED display is not maintained and cleaned for a long time, the pixel failures on the display will increase.
There are several main types of pixel failures, such as dead points, which are pixels that do not emit light at all, and dark points, which are pixels with extremely low brightness.
Bright points, which are pixels that emit too brightly. These failure points are like “defects” in the picture, which particularly affect the visual effect.
If the display is not cleaned and maintained for a long time, a lot of dust will accumulate on the surface and inside of the display. There are many impurities in the dust, and some impurities may also be conductive.
If these conductive impurities adhere to the pixels, they will interfere with the normal operation of the pixels and increase the probability of failure.
It is like the impurities in the dust are like “troublemakers”; they will interfere with the normal light emission of the pixels, causing the pixels to appear as dead points, dark points, or bright points.
These pixel failures have a great impact on the integrity of the display. For example, black spots or bright spots in the picture will destroy the continuity and beauty of the picture.
Imagine that you are watching a movie, and suddenly, a few particularly bright spots or black spots appear in the picture.
It must be uncomfortable. Moreover, the more pixel failures there are, the uglier the picture will be.
Repairing pixel failures is not an easy task. Generally speaking, repairing a pixel point may require professional equipment and technicians, and the cost is not low.
Moreover, if there are too many failure points, the entire display module may need to be replaced, which is even more troublesome.
For example, if there are hundreds of pixel failures on a display, it will not only be time-consuming and labor-intensive to repair but also very expensive.
If you clean and maintain it regularly, you can reduce dust accumulation and reduce the probability of pixel failures, thereby reducing the maintenance burden and cost.
Consequence 5: Shortened life of LED display
If the LED display is not maintained and cleaned for a long time, its life will be “suffering.” First, the brightness of the display will gradually dim.
Just like a light bulb gets dimmer after a long time, dust and stains accumulate on the screen, blocking the light and making the screen look darker.
Moreover, the heat cannot be dissipated, which will cause the lamp beads to age faster. Secondly, the color will become inaccurate.
The impurities in the dust will interfere with the operation of the pixels, making the colors look darker or yellower.
Furthermore, the heat dissipation performance will deteriorate.
When the heat dissipation channel is blocked by dust, the temperature inside the display will rise, which will cause the electronic components to age faster and may even short-circuit. Finally, there will be more and more pixel failures.
Impurities in the dust may cause dead spots, dark spots, or bright spots in the pixels, and these failure points will destroy the continuity and beauty of the picture.
The interaction of these factors will greatly shorten the life of the display. For example, a properly maintained LED display can be used for 6-10 years, while a display that has not been maintained for a long time may break down in 3-5 years.
For example, some outdoor displays in harsh environments may need to be replaced in 3-4 years if they are not cleaned and maintained.
From an economic point of view, the cost of regularly maintaining and cleaning LED displays is actually very low.
Assuming that it is cleaned once a quarter, it costs about 500 yuan each time, which is 2,000 yuan a year.
Add some small maintenance costs, and it will be about 3,000 yuan a year. But if the display screen breaks down prematurely due to lack of maintenance, the replacement cost will be high.
A medium-sized LED display screen may cost 50,000 to 100,000 yuan to replace. Therefore, regular maintenance and cleaning can not only extend the service life of the display screen but also save a lot of money.
It’s like you regularly maintain your car. Although it costs a little money each time, it can avoid major repairs, which is still cost-effective in the long run.
6. How to avoid the above consequences?
To avoid problems such as brightness attenuation, color deviation, reduced heat dissipation performance, and increased pixel failures on LED displays, the method is actually very simple.
The key lies in regular maintenance and cleaning. Here are some practical suggestions:
Every once in a while, such as every quarter or half a year, give the display screen a “big clean.” Gently wipe the surface of the screen with a soft cloth to remove dust and stains.
If the display screen is dirty, you can use some special cleaning agents, but make sure that the cleaning agents will not damage the screen.
Regularly check the cooling channels and heat sinks of the display screen to see if there is any dust accumulation.
If there is, clean it in time to ensure that the cooling system can work properly.
It’s like maintaining the “air conditioner” of the display screen so that it can smoothly dissipate the heat.
When using the display screen at ordinary times, pay more attention to the display effect of the screen.
If you find that some pixels are not emitting light normally or the color of the picture is deviated, you should deal with it in time.
It’s like doing a “physical examination” of the display screen and solving the problem early to avoid small problems from becoming big troubles.
If you don’t understand technology very well, you can ask professional technicians to regularly maintain the display screen.
They have professional tools and experience and can check and maintain the display screen more comprehensively and professionally to ensure its healthy and stable operation.
In short, as long as you develop a good habit of regular maintenance and cleaning, you can effectively avoid these consequences, keep the LED display screen in good condition, and use it longer and more safely.
