I don’t know if you have ever encountered such troubles: in an environment with strong sunlight or dazzling lights, the content on the 발광 다이오드 표시 스크린 becomes blurred and gives people a headache.
This not only affects people’s viewing experience, but sometimes, it may also delay things because of unclear information.
So, today, I want to talk to you about how to keep the LED display screen clear in a strong light environment and give you some practical tips and suggestions.

1. Does strong light have such an impact on LED display screens?
1). Interference with the visual effect of LED display screens
Do you know that strong light is a big source of interference in the visual effect of LED display screens?
When we look at LED display screens, we think they are quite bright and clear, but that is under normal circumstances.
If it is a sunny day, direct sunlight, or those super strong lights at night, the display screen will seem to have changed.
First of all, strong light will make the relative brightness of the LED display screen insufficient. Think about it, the display screen itself has brightness, but if the surrounding environment is too bright, the brightness of the display screen will not be enough.
In this way, the image contrast on the screen will decrease, and the originally clear black and white and color boundaries will now become blurred and unclear.
In addition, strong light will also reduce the color saturation of the display. Color saturation, to put it simply, is the vividness of the color.
In a strong light environment, the light emitted by the display and the ambient light are mixed, and the color becomes dim and loses its original vividness.
This not only makes the eyes uncomfortable, but also affects the information transmission.
2). Problems that affect the viewing experience, such as reflection and glare of LED display screens
In addition to affecting the brightness of the display screen, strong light will also cause reflection and glare problems.
Reflection means that strong light shines on the display screen and then reflects back and enters our eyes. Imagine that when the sun is shining directly, are there often bright spots on the display screen?
That is reflection. Reflection will make us unable to see the content on the screen clearly, and sometimes important information is covered by the light spots.
Moreover, looking at the reflective display screen for a long time will make the eyes very tired, and even the vision may decline.
Glare is even more uncomfortable. It is a strong light shining directly into our eyes, making our eyes sting, tear up, and blink non-stop. Sometimes, the glare is so severe that we can’t even open our eyes, let alone see the content on the display.
If this continues for a long time, the retina may be damaged, and the health of vision will be affected.
So, reflections and glare not only affect our experience of viewing the display, but may also cause damage to the display itself.
Long-term exposure to strong light may cause the surface of the display to age, discolor, and even scratch. Moreover, electronic components may also accelerate ageing due to excessive heat.
Strategy 1: Choose an LED display suitable for strong light environments
When it comes to dealing with strong light, high-명도 LED displays are masters.
Its brightness is particularly high, like a small sun, which can emit strong light so that even if the surrounding environment is bright, the content on the screen can be seen clearly.
Moreover, high brightness can also increase the viewing angle of the screen so that no matter where you look at it, you can see the content on the screen.
When choosing an LED display, brightness is a key indicator. You have to see how bright the surrounding environment is and then choose a screen with appropriate brightness.
For example, in an outdoor environment, the sunlight is so strong that you have to choose a screen with particularly high brightness.
The indoor environment is relatively dark, so just choose a screen with moderate brightness. When choosing, don’t forget to look at the brightness parameters of the screen and then choose the most suitable one based on the actual situation.
Now that technology is so advanced, anti-glare and anti-reflective coating technologies have come out.
This technology is like putting a layer of “magic clothes” on the screen, which can reduce reflections and glare.
The anti-glare coating can make the light spread evenly on the screen, which will not be so dazzling; the anti-reflective coating can absorb or reflect part of the light, making the screen content clearer.
With this technology, the screen can be comfortable to watch even in strong light.
Strategy 2: Optimize the installation position and angle of the LED display
1). Choose a suitable installation position
The installation position of the LED display is a big question. If the screen is installed under direct sunlight or strong light, the screen will suffer. The strong light will make the screen content unclear.
Therefore, when installing the screen, you have to avoid sunlight and strong light sources and find a suitable place.
2). Avoid installation under direct sunlight or strong light sources
Avoiding direct sunlight or strong light sources is actually quite simple. You can install the LED screen inside a building, under the shade of a tree, or in an awning, all of which can block sunlight and strong light sources.
You can also use sunshades and sun visors to block light. If conditions permit, it is better to install the LED screen in an indoor or semi-indoor environment so that you don’t have to worry about strong light problems at all.
3). Adjust the angle of the display to reduce reflections and glare
In addition to choosing a good location, you can also adjust the angle of the LED screen to reduce reflections and glare.
You can adjust the tilt angle and direction of the screen according to the position and angle of the audience looking at the screen, as well as the lighting conditions of the surrounding environment.
For example, tilting the screen slightly can reduce reflections and glare or adjust the direction of the LED screen to make it more comfortable for the audience. When adjusting, you need to try more to find the most suitable angle and direction.
Strategy 3: Use shading facilities to improve the clarity of LED display
1). Use shading facilities such as sunshades and sun visors
Did you know that sunshades and sun visors are like “sunshades” for LED display screens? Their main task is to block direct sunlight or strong light sources so that the screen is no longer troubled by reflections and glare.
In this way, even on sunny days or in places with particularly bright lights, the content on the LED screen can be seen clearly, and the audience’s eyes can be much more comfortable.
2). How do you design and install shading facilities?
Designing and installing shading facilities is actually like customizing “sun protection clothing” for the screen. First, you have to see where the LED screen is installed, what the surrounding lighting conditions are like, from which direction the sunlight comes, and how the lights are arranged.
Then, think about where the audience will look at the screen and what their viewing angles are. Based on these, you can design the shape, size, and installation location of the sunshade or sun visor.
When installing, make sure the equipment is stable and will not be shaken by the wind. Also, the distance and angle between the equipment and the screen must be adjusted properly to achieve the best shading effect.
3). Will the shading equipment make the screen hotter? Don’t worry, there is a way!
Shading equipment may indeed make the air circulation around the LED screen worse, causing the screen temperature to rise slightly.
But don’t worry, we have a way to solve it. When designing the equipment, you can leave some vents or heat dissipation holes to allow air to circulate.
Or, choose some materials with good heat dissipation performance to make the equipment. If you still feel that it is not enough, you can also install a fan or heat sink on the screen to ensure that the screen will not overheat.
Strategy 4: Adjust the display settings to enhance readability
1). Adjust brightness, contrast and other parameters to adapt to strong light environments
In strong light environments, the brightness of the LED screen needs to be increased so that the content can be more prominent and the audience can see clearly. The contrast also needs to be adjusted to make the picture more layered and clearer.
How do we adjust it specifically? You can try to see the effect and adjust it slowly until you are most satisfied.
2). For colour correction and colour temperature adjustment
Colour correction and colour temperature adjustment are also very important. Colour correction can make the colour displayed on the LED screen more accurate and will not make the audience feel that the colour is weird.
Colour temperature adjustment is to make the colour of the screen look more natural and comfortable according to the surrounding lighting conditions. How to do it? You can use professional colour correction tools or software to help.
After adjusting it, you will find that the picture looks much more comfortable!
3). Optimization of 재생률 그리고 명확성
The refresh rate is the number of times the LED screen refreshes the image per second. The higher the refresh rate, the smoother and clearer the picture. In strong light environments, the refresh rate cannot be ignored.
You have to choose a suitable refresh rate according to the type and purpose of the screen.
Especially for those images or video content that require high-speed movement, the refresh rate should be increased to ensure that the picture is clear and not blurry. Therefore, it is also necessary to check and adjust the refresh rate setting regularly!
Strategy 5: Use advanced technology to improve the ability to resist strong light
1). Use dynamic contrast adjustment
Dynamic contrast adjustment technology is like the “smart glasses” that come with an LED display.
It contains a light sensor or a super algorithm that can stare at the content on the screen in real-time to see whether it is bright or dark and then automatically adjust the brightness and contrast of the display.
In dark places, it dims the backlight to make the details clearer; in bright places, it brightens the backlight to make the colours more vivid.
In strong light, this technology is simply a lifesaver. It can keep the dark details of the LED display from being lost and the bright colours from being white.
By intelligently adjusting the brightness and contrast, the overall clarity and visual effects of the display are greatly improved.
In this way, even under the scorching sun, you can clearly see the content on the screen and enjoy a great visual experience.
2). How to use local dimming
Local dimming technology, especially FALD and Mini-LED, is like installing a “local beautification” on the display. It allows the LED backlight block behind the screen to independently control the brightness, bright or dark as you want.
Mini-LED uses ultra-small LED lamp beads to make the backlight block more dense and more precisely controlled.
The benefit of this technology is that it can reduce halo, making the picture more layered and three-dimensional. Under strong light, black is blacker, white is brighter, and the colour is fuller.
By precisely controlling the brightness of different areas, local dimming technology can greatly improve the clarity and viewing experience of the display, making you feel like you are in the scene.
Strategy 6: Regular maintenance and inspection to ensure long-term clarity
1). Regularly clean the display surface
Regularly clean the display surface, this job can not be lazy. LED display screens are exposed to the outside every day, and dust, dirt, and rain are all rubbed up.
These dirty things not only make the display screen look bad but also affect the clarity and brightness and may even scratch the screen.
Therefore, you have to wipe it gently with a soft cloth, and don’t use hard objects or rough cloth to scratch the screen.
If there are stubborn stains, use a professional screen cleaner, but use it according to the instructions, and don’t let the cleaner penetrate and damage the screen.
According to the environment and usage, set a reasonable cleaning frequency, such as cleaning at least once a month or wiping it in time when it is dirty.
2). Check the display screen connection cable and interface
The display screen connection cable and interface are like the “lifeline” of the LED display. If they are loose or broken, the signal will not be transmitted well, affecting the clarity, and may even not be displayed.
Therefore, you have to regularly check whether the connection cable and interface are loose or broken. If they are loose, plug them tighter, and if they are broken, replace them with new ones as soon as possible.
You also have to see if the layout of the connection cable is reasonable. Don’t bend too much or pull too tight, which is easy to break. It is recommended to check at least once a quarter or check and deal with problems in time if they are found.
3). Maintenance suggestions for ageing and damage of the display screen
3.1). Replace wearing parts regularly
The LED lamp beads and driver chips in the LED display are all easy to break. After a long time of use, they will age or break, affecting the clarity and brightness and may even cause the entire display to go out of service.
Therefore, you have to regularly (such as every year or every two years) conduct a comprehensive inspection of the LED display and replace the aged LED lamp beads and driver chips in time.
You also have to prepare some wearing parts so that you can replace them when needed to keep the display in good condition.
3.2). Adjust the use environment and parameters
The use environment and parameter settings of the LED display will also affect its clarity and life. For example, if the brightness is set too high, the LED lamp beads will easily age; if the same thing is displayed for a long time, it is easy to “burn the screen”.
Therefore, you have to adjust the brightness and contrast of the LED display in time according to environmental changes to make the display last longer. You also have to avoid displaying the same thing for a long time. You can change the content regularly or set a screen saver.
3.3). Professional maintenance service
If there is a big problem with the LED display, such as a large area of black screen, wrong color, etc., we can’t fix it ourselves, so we have to find a professional repair. Professional maintenance personnel can quickly find the problem and provide a solution.
We have to keep in good communication with them, understand the progress and results of the repair, and let the display return to normal as soon as possible.
In summary, using advanced technology to improve the ability to resist strong light and then regular maintenance and inspection, the LED display can be clear even under strong light, which makes the audience feel comfortable, and we can use it with confidence.
It can also extend the life of the display and save maintenance money, killing two birds with one stone!
8. Strategies for dealing with special strong light environments
1). Challenges of special strong light environments such as outdoor and 단계
Outdoor and stage, these two places are simply “extreme challenge” sites for LED displays.
Outdoor, the sun is so strong that it shines directly over, and the display is like being covered with a layer of white gauze, and nothing can be seen clearly.
On the stage, the lights change back and forth as fast as lightning, and the colour of the display is crooked if you are not careful, and it flashes, which is a headache.
Moreover, the outdoor environment is changeable, and wind and rain come at any time. The LED display screen must be waterproof and dustproof. On the stage, the sound is deafening and the audience dances along.
The display screen must be stable and not break down when shaken. In addition, the display screen is easy to heat up under strong light, so you have to find a way to dissipate the heat, otherwise it will be troublesome if it burns out.
The brightness of the outdoor LED display screen must be high enough; otherwise, you can’t see anything when the sun shines.
The contrast must also be adjusted well to make the picture layered and not plain. Only in this way can the audience see the picture clearly and enjoy the visual feast.
Glare is really annoying and makes people unable to see the screen clearly. So you have to choose an anti-glare screen to reduce light interference.
However, when choosing, you must pay attention to the light transmittance and clarity. Don’t blur the picture for anti-glare.
Outdoor and stage, the environment is complex, and the display screen must be waterproof and dustproof. When choosing, you must pay attention to whether it has these functions.
You also need to be careful when using it, check and maintain it regularly, and don’t let water or dust get in.
The LED display on the stage must be stable.
When the sound shakes, the audience jumps, and the display screen should not shake. When choosing, you must choose one with good earthquake resistance, and when installing, you must also fix it well and don’t let it shake.
Under strong light, LED display screens are prone to heat up. You must choose one with good heat dissipation performance, and you must ensure ventilation.
Otherwise, it will be troublesome if it is damaged by heat. You must also pay attention when using it, don’t turn it on for a long time, and take a proper rest.
2). Mention the possibility of customized display solutions for special needs
Did you know? Now, you can customize LED display screens! For outdoor use, you can order a super high brightness, wide viewing angle, and no matter how strong the sun is. For stage use, you can order a fast response with bright colours no matter how the lights are changed.
Moreover, you can also customize the size, shape, and installation method. You can get as big as you want, as round as you want, and as wall-mounted as you want. In short, you can get whatever you want to meet all your needs.
So, it is important to choose the right LED display to deal with special strong light environments.
The brightness and contrast must be sufficient, the anti-glare must be done well, the waterproof and dustproof must be necessary, the anti-seismic performance must keep up, and the heat dissipation problem must be solved.
If you want a more perfect solution, you can also customize the display! In this way, whether outdoors or on stage, the audience can enjoy the best visual feast!
9. 결론
Through the above sharing, I believe you have learned a lot about how to maintain the clarity of LED displays in strong light environments.
Don’t forget those high-tech technologies and regular maintenance inspections, which are also the key to keeping the display in the best condition.
