LED 디스플레이, as the core carrier of modern visual communication, have been deeply integrated into our daily lives. But can’t LED displays be universal? Why is there a difference between indoor and outdoor? If you have the same question, follow this article to explore the reasons!
Reason 1: Different usage environments
1). Indoor environment:
If you sit in a comfortable home, the air conditioner blows gently, and the air humidity is just right, neither dry nor humid. This is the charm of the indoor environment. For electronic devices, such an environment is simply a “gentle country”.
- 온도 및 습도:
Just like people, electronic devices also like a stable environment. The constant temperature and humidity conditions indoors save them a lot of “thermal expansion and contraction” troubles, and the internal circuit components can work safely and steadily without failure.
For this reason, the materials of LED displays can be maintained for a longer time and are not easy to deform or age.
- 조명 조건:
Indoor light is usually softer. For example, LED displays in shopping malls are almost not exposed to any sunlight and will not be exposed to sunlight.
Even if the sunlight comes in, it is warm and gentle. In this way, the LED display screen does not need to desperately increase its brightness to fight against strong light, which saves electricity and protects the eyes.
- Dustproof and waterproof:
Indoors, once the doors and windows are closed, the outside world cannot get in no matter how dusty it is. Therefore, electronic equipment does not need to worry too much about the intrusion of dust and water when designing.
In this way, designers can focus more on improving the performance and appearance of the equipment, rather than how to waterproof and dustproof.
- . Outdoor environment:
Once you walk out of the room and enter the outdoors, it will be a different scene. The outdoor environment is like an adventure field full of challenges and opportunities. For electronic equipment, every step is full of tests.
- Temperature changes:
The temperature of the outdoor environment is like a child’s face, which changes at any time. From the high temperature in the hot summer to the low temperature in the cold winter, LED displays must be able to withstand such extreme tests.
This requires them to use materials that can withstand extreme temperatures when designing and have good heat dissipation or insulation mechanisms to ensure that the equipment will not go on strike due to overheating or overcooling.
- Natural environment:
The outdoor environment is truly “original ecology”. Sunlight, rain, wind and sand are all what LED displays need to face directly. Waterproof and dustproof have become standard features of outdoor LED display screens, otherwise a sudden rainstorm or a gust of sandstorm may cause the device to “strike”.
Outdoor LED display screens need special reinforcement to prevent scratches by sandstorms or reflections and glare caused by direct sunlight.
- Brightness requirements:
Outdoors, sunlight is one of the most powerful “opponents.” In order for users to see the content of the LED screen clearly, even in strong sunlight, the brightness of the LED display screen must be high enough.
This requires a more powerful backlight system or more advanced display technology to support it. Of course, this also brings challenges in power consumption and heat dissipation. Designers need to find the best balance between brightness and power consumption.
Reason 2: Differences between technical requirements and design
1). 명도 대조:
Imagine sitting in a conference room and watching a very important project report meeting. At this time, you hope that the brightness of the LED display screen is moderate, not too dazzling, but not too dark so that you can see every detail on the report PPT.
This is the brightest design of indoor LED display screens, which pursues comfort and delicacy so that you can feel the rich layers of color and the delicate texture of the picture in a comfortable situation.
As for the outdoors, it is a different story. You are standing in the square, the sun is shining, and there are bustling people around you. At this time, if the screen brightness is not enough, you may have to squint and try hard to see the content on the screen clearly.
Therefore, the brightness of the outdoor screen must be designed to be high enough to ensure that it can be clearly seen even under strong light. But at the same time, designers must cleverly control reflections and glare so that you will not feel uncomfortable when looking at the LED screen, just like looking at the scenery.
2). Protection level:
Speaking of protection level, we can compare it to raincoats and armor. Indoor LED display screens are like the raincoats you usually wear. Although they can also prevent a little rain, they are mainly used to deal with small dust and occasional splashes in daily life.
Therefore, it is enough for its protection level to reach IP20 or IP30, which can prevent fingers or slightly larger dust particles from entering, and the requirements for waterproofing are relatively low.
As for 옥외 LED 스크린, they are like armor worn by soldiers, which must be able to withstand the invasion of various harsh environments. Whether it is a storm or dust, it can remain as solid as a rock.
Therefore, the protection level of the outdoor screen must be at least IP65 or above, which means that it can effectively resist the intrusion of rain and dust, protecting the screen like armor and allowing it to operate stably in harsh environments.
3). Weather resistance and stability:
We can compare weather resistance and stability to long-distance running and marathon. Indoor LED display screens are like your usual running and fitness. Although they also require a certain amount of endurance and stability, overall, the difficulty is not particularly great.
It focuses on the reliability of long-term stable operation to ensure that there will be no problems when you use it.
As for outdoor screens, it is like participating in a marathon. It must withstand the test of various extreme weather conditions, whether it is hot or cold, it must be able to persist.
Moreover, it must withstand various challenges such as ultraviolet radiation and wind and sand invasion, just like marathon runners constantly breaking through themselves on the track. Therefore, outdoor screens must have excellent weather resistance and stability to ensure that they can work normally in harsh environments.
4). Installation and maintenance:
Finally, let’s talk about installation and maintenance. The installation of indoor LED display is like the decoration of your home, which is relatively simple and convenient.
You just need to find a suitable location, fix the screen, and then connect the power and signal cables. It is also relatively easy to maintain, just clean and check it regularly.
The installation and maintenance of outdoor screens are as complicated and cumbersome as tooling. First of all, you have to consider the structural strength of the screen to ensure that it can be firmly fixed in the designated position and will not be blown down or damaged by the wind.
Secondly, you have to consider the problem of lightning protection to ensure that the equipment can operate safely in thunderstorms.
Finally, since dust and dirt easily accumulate in the outdoor environment, cleaning outdoor screens is more frequent and complicated. All of these will lead to relatively high installation and maintenance costs for outdoor screens, which require professional teams and tools to complete, just like tooling.
Reason 3: Application scenarios and demand analysis
1). Application scenarios of indoor LED display screens:
- Commercial center:
If you are strolling in a busy commercial street, suddenly, a huge LED display screen attracts your attention. It plays the latest fashion show, and the models are dressed in gorgeous costumes and dance on the screen.
