Why LED crystal film screens are not suitable for outdoor glass?

1. Analysis of technical characteristics and limitations of LED crystal film screens

1). Technical characteristics

1.1). High transparency

The light transmittance of LED crystal film screens is as high as 95%! This means that when the screen is not lit, it is like it does not exist, and it will not block the scenery or light behind you at all.

This design is really clever, especially for those who want to keep the space open and do not want to destroy the original appearance of the building, whether it is a store window, an interior decorative wall, or other places that require a transparent display, LED crystal film screens can bring a supernatural visual experience.

1.2). Flexible and thin

The LED crystal film screen not only has good light transmittance but is also very thin and soft. It is only 1.35 mm thick and surprisingly light, weighing only 1 to 3 kg per square meter. This design allows the LED crystal film screen to be bent and cut at will to adapt to various strange shapes and surfaces.

It is also super convenient to install, without the need for additional steel structure support, and can be directly attached to glass or other smooth surfaces. In this way, whether it is a curved wall, a cylinder, or other irregular objects, it can be turned into a cool display.

1.3). Easy installation

When it comes to installation, the LED crystal film screen is really easy. There is no need for a complicated installation process or an additional support structure. Just stick it on. This not only saves installation time but also greatly reduces costs.

Whether it is a new building or the renovation of an old building, the LED crystal film screen can be easily integrated, adding a unique technological charm to the building.

2). Limitation analysis

2.1). Weak UV resistance

However, the LED crystal film screen also has its minor disadvantages. Because its lamp beads and circuits are exposed, they are prone to oxidation and aging when exposed to strong ultraviolet rays outdoors for a long time. In this way, the brightness of the screen will decrease, the color will become inaccurate, and it may even affect the service life.

Therefore, if used outdoors, you must take some additional protective measures, such as installing a sunshade or applying some anti-ultraviolet paint to protect the screen from ultraviolet damage.

2.2). Insufficient waterproof and dustproof performance

In addition, the outdoor environment is very complicated, and rain, dust, etc., may pose a threat to the LED crystal film screen. If the waterproof and dustproof level is not high enough, the components inside are easily damaged, causing the screen to fail to work properly.

Therefore, when using it outdoors, you must choose an LED crystal film screen with a high waterproof and dustproof level and perform regular maintenance and cleaning to ensure the normal operation of the screen and extend its service life.

2.3). Limited temperature adaptability

Also, the large temperature difference outdoors is a problem. Extreme high or low temperatures may have adverse effects on LED crystal film screens. In a high-temperature environment, the screen may be damaged, or its performance may deteriorate due to overheating; in a low-temperature environment, the screen may not work properly due to freezing.

Therefore, when choosing and using the LED crystal film screen, you must consider its temperature adaptability and take necessary insulation or heat dissipation measures to ensure that the screen can work stably under various temperature conditions.

In summary, although the LED crystal film screen has technical characteristics such as high permeability, flexibility, thinness, and easy installation, it also has limitations such as weak UV resistance, insufficient waterproof and dustproof performance, and limited temperature adaptability when used outdoors.

Therefore, when choosing and using the LED crystal film screen, you must comprehensively consider its technical characteristics and limitations to ensure that it can meet your actual needs.

2. What will happen if the LED crystal film screen is installed on outdoor glass?

1). Positive effect

1.1). Unique visual effects and advertising display

The 95% transmittance of the LED crystal film screen is really great! When playing content, the picture is clear and bright. When not playing, it is almost invisible, and it does not affect the view of the scenery behind it.

This feature makes the LED crystal film screen on outdoor glass a super cool advertising display platform, and everyone passing by will be attracted. Dynamic images, bright colors, and great advertising effects!

For places such as commercial blocks and shopping centers, installing LED crystal film screens can greatly enhance the brand image and popularity.

1.2). Enhance the aesthetics of the building

The LED crystal film screen is designed to be light and thin, and it is perfectly integrated with the glass without destroying the overall sense of the building. Moreover, once the dynamic image is put on, the building immediately has a more modern and technological sense and looks more fashionable and avant-garde.

It can also be customized according to the shape and style of the building so that the building and the screen are perfectly matched, and the aesthetics rise sharply.

2). Potential problems and challenges

2.1). Anti-ultraviolet and aging problems

The lamp beads and circuits of the LED crystal film screen are exposed to the outside, and they are easily oxidized and aged when exposed to the sun for a long time. The screen will become dark, the color will be distorted, and even the service life will be affected.

If the location where you install it is exposed to direct sunlight all year round and the temperature is high, there may even be a risk of surface melting. Therefore, some protective measures should be taken, such as installing a sunshade or using some anti-ultraviolet materials. Regular cleaning and maintenance are also required to keep the screen clean and bright.

2.2). Waterproof and dustproof performance requirements

The outdoor environment is complex, and rain and dust may damage the LED crystal film screen. If the waterproof and dustproof level is not enough, the components inside are easily damp or dusty, and the screen cannot work properly.

Therefore, when choosing an outdoor LED display, you must choose a high waterproof and dustproof level, generally IP65 or higher.

2.3). Temperature adaptability test

The outdoor temperature difference is large, and high or low temperatures may affect the performance of the LED crystal film screen. High temperature may cause the screen to overheat and break, and low temperature may cause the screen to freeze and fail to work.

Therefore, some heat dissipation and insulation measures must be taken, such as installing an axial fan to dissipate heat or wrapping the screen with insulation materials.

When choosing a screen, you must also consider temperature adaptability and choose one that can work normally under extreme temperatures.

2.4). Installation and maintenance difficulty

The outdoor glass installation location must consider factors such as load-bearing, field of view, and maintenance. If the location is not chosen well, it may affect the stability and service life of the screen.

In addition, the outdoor environment is complex, and maintenance costs are high. Regular inspection and maintenance are required to ensure that the screen works properly.

Therefore, the load-bearing capacity of the glass must be evaluated before installation, and the appropriate installation method must be selected. A maintenance plan must also be formulated to regularly clean, inspect, and repair the screen.

3. Special requirements for LED screens in the outdoor glass application environment

1). Environmental adaptability

The outdoor glass application environment is really changeable, and the environmental adaptability of the LED screen is a big test.

1.1). Anti-ultraviolet:

Outdoor LED screens have to be exposed to the sun for a long time, and the ultraviolet rays are so strong that the screen material must be able to withstand it.

Therefore, special anti-ultraviolet materials or coatings must be used to make the screen bright and lasting, and it will not fade or darken even if it is exposed to the sun for a long time. It must also undergo rigorous testing to ensure that it is still good for several years.

1.2). Waterproof and dustproof:

Outdoor weather changes quickly, and rain, wind, sand and dust all rub against the screen. LED screens must have a high waterproof and dustproof rating, such as IP65 or higher, so that they can block these "little troublemakers" in nature.

The waterproof design must prevent rain from entering, and the dustproof design must prevent dust from entering, so that the screen can always remain clear.

1.3). Temperature regulation:

The temperature difference outdoors is terrifying. It is extremely hot in summer and shivering in winter. LED screens must be able to adapt to such extreme temperatures so as not to be damaged by heat in summer and frozen in winter.

Therefore, the screen must be equipped with an efficient heat dissipation system, such as heat pipes, fans, etc., so that the screen can be cool even at high temperatures. In winter, some heating elements may need to be added to allow the screen to work normally, even at low temperatures.

2). Display effect and stability

For LED screens on outdoor glass, both display effect and stability are very important.

2.1). High brightness and contrast:

The outdoor sunlight is so strong that the LED screen must be bright enough to be seen clearly. The brightness must be high, several thousand nits or even higher, to compete with the sunlight.

The contrast ratio must also be high, the black must be completely black, and the white must be bright white, so that the image and text can be clear.

2.2). Wide viewing angle:

The outdoor LED screen must be visible to many people. Whether it is viewed from the front, from the side, or even from an angle, it must be equally clear.

Therefore, special LED lamp beads and optical structures must be used to allow the screen to present the same good display effect at all angles.

2.3). Stability:

The outdoor environment is so complex that the LED screen must be stable. The components and connecting lines inside must be reliable and durable and don't go wrong at any time.

It must also undergo various rigorous tests, such as long-term continuous operation tests, extreme temperature tests, vibration tests, etc., to ensure that the screen can work normally under various conditions.
