Yes. Our high-quality outdoor LED screens are specifically designed to withstand all weather and environmental conditions such as heavy rain, extreme sunlight, snow, ice, high humidity, strong winds & dusty environments.
The Outdoor LED Displays are not all made equal. The key factors that affect the long-term reliability of an outdoor LED display include the IP rating of the display, the material of the cabinet, thermal management, the degree to which the display is waterproof sealed, wind resistance, protection from power surges and regular scheduled maintenance.
Whether you are planning to install a roadside billboard, a display in a stadium, a transport sign or even a network of digital signs, this information will help you choose your display so that it continues to run optimally for years to come.
This guide covers three main points: How outdoor LED screens cope in very bad weather, the important technical parameters and things to watch out for before buying.
| Weather Condition | Key Protection Features |
| Heavy Rain | IP65/IP66 waterproof cabinet, silicone sealing |
| Dust & Sand | Dustproof enclosure, sealed LED modules |
| High Temperature | Intelligent cooling system, aluminum cabinet |
| Low Temperature | Industrial-grade components, anti-crack materials |
| Strong Wind | Reinforced steel structure, wind-load engineering |
| Lightning | Grounding system + Surge Protection Device (SPD) |
| High Humidity | Conformal coating, anti-corrosion treatment |
| Coastal Environment | Salt-spray resistant cabinet, waterproof connectors |
A reliable outdoor LED display has to fulfill a number of requirements based on internationally recognized standards.
· IEC 60529 for IP (Ingress Protection) ratings
· IEC 62368-1 for electrical safety
· IEC 61000 series for electromagnetic compatibility (EMC)
· Certifications UL, CE, RoHS, FCC where applicable.
While for most of the outdoor advertising applications IP65 would be the minimum degree of protection recommended, in case of very adverse weather conditions IP66 or higher would be required.
We design our outdoor LED displays to withstand the type of use that an indoor display would not be able to handle. They are made of a strong and durable outer casing, with a variety of seals throughout the display, and use weather resistant materials to protect against adverse weather such as rain, dust, extreme temperatures and strong winds. The cabinet for our Outdoor High Resolution Digital Advertising Screen P10 Full Color LED Screen is made from die-casting aluminum with an IP65 rating. It can operate in temperatures as low as -20°C and as high as 50°C. This is to allow for use in a variety of climates and to ensure that the screen continues to function to its full potential.
A good display starts with a solid outer housing or casing. Typically, displays are made of aluminum or steel and are protected from corrosion. The housing of the P10 outdoor display is incorporated into a cabinet with the dimensions of 960×960mm. The die-casting aluminum housing has a weight of 28 kg and is therefore strong enough for outdoor applications in large dimensions. At the same time, however, it is also light enough to be moved. The individual display modules are hermetically sealed to outside influences of moisture and dust in order to prevent short circuits. The aluminum housing is then coated with an anti-corrosion coating in order to protect against weather influence, particularly in areas with high humidity and in coastal areas with air containing a lot of salt.
Ingress Protection (IP) rating indicates the level of protection against dust and water of display solutions. With an IP65 rating, our products are completely protected against contact with objects like solid dust and prevent damage caused by ingress of liquids during temporary submersion in water. As indicated in Longcheng’s product specifications, the P10 display with an IP65 rating is suitable for use in very wet and dirty weather, during heavy rain and high humidity. Seals must be in good condition around all connectors and panels to prevent short circuits in storms. These seals must be regularly inspected to ensure that they remain intact and do not allow moisture to penetrate.
Temperature can have a large effect on products and packaging materials. Implementing a thermal management system could help control the internal temperature of a product, helping to combat the high or low temperatures that the product is exposed to.
For higher ambient temperatures external fans or heat sinks can be mounted to avoid overheating. Intelligence sensors measure temperature and automatically adapt cooling if necessary. In freezing cold climates flexible materials are used for mobile outdoor installations which are resistant to low temperatures and do not crack. The P10 outdoor full-color display is qualified for operation between -20°C and +50°C and for storage between -40°C and +60°C. Thus it can be operated in almost every part of the world and in almost all climatic situations.
To maintain constant voltage output even under changing temperature conditions industrial power supply is used. Low power consumption is achieved by high quality signal processing of the driver ICs as well as by adaptive brightness control. This means that during warm weather the power consumption as well as the temperature rise is kept at a minimum.
Even when operating outdoors, moisture penetration is still one of the biggest reasons for failure of electronic equipment. Modern outdoor LED display systems are designed with several layers of water protection.
To prevent water damage silicone seals are applied to the connecting points as well as the edges of the solar modules. In the cabinet structure there are drainage channels, which enable any rainwater to leave the cabinet quickly. The protective glass has a hydrophobic coating on the surface. This coating minimizes the condensation on the glass surface. Thus, a clear view is guaranteed even in rainy and stormy weather.
To combat corrosion by humidity on circuit boards they are covered with a so-called conformal coating. In enclosures desiccant packs are stored to absorb humidity which may penetrate at a later time. For long-term stability in tropical or coastal climates the enclosures are designed to be air-tight and are provided with controlled ventilation in order to avoid penetration of moisture.
Some areas have strong winds or sandstorms and therefore need additional mechanical strength and dust protection.
Cabinets can be tested in wind tunnel tests to check their resistance to gusts of wind at certain speeds without deformation or detaching from the fastening structure. Even very large displays can be mounted on poles or walls by means of reinforced brackets. Due to the flexible connections, also vibrations caused by wind pressure are absorbed by the bracket and do not cause any mechanical stress. Such stress could cause a fatigue failure of the bracket within a short period of time.
The very small particles are caught by filters and/or by mesh screens that prevent them from entering into the air flow streams. The surfaces of the display modules can be treated to a coating so that the dust does not stick to them. There is no need for more frequent maintenance. Large numbers of displays in a desert environment could be automatically cleaned.
Lightning damage to an outdoor electronics installation can be extreme, largely due to the inadequacy of the grounding of the installation.
Multi-point grounding provides all frames in a building with a balanced potential, and can counteract voltage differences caused by a lightning strike. A deep-buried, large copper grounding rod has a low resistance, and can divert a lightning stroke around sensitive equipment.
Transient overvoltages caused by a lightning strike or a short term grid disturbance are dissipated by SPDs at main power entry points. In addition to protecting the power supply lines, Layered Protection also protects all data transmission lines in the system from electrical damage.
Although modern designs have developed highly and are efficient, by implementing proper and scheduled maintenance throughout the life span of designs, increased efficiency of designs can be obtained.
Checking for signs of deterioration on components such as corrosion and also for signs of cracking of protective coatings, and for loose fittings before they can cause a major failure. In addition Electrical Continuity tests on all connections between modules to confirm current is flowing correctly and no part of array is being ‘screened out’ to cause partial failure.
Cleaning the screen with gentle cleaning products which are non-abrasive removes the polluting agents without any risk of damaging the waterproof coating of the screen or scratching the anti-glare surface. The regular check and readjustment of brightness of images also maintains the colorimetry of the images and gives homogeneous image quality to all screens, even after a long time and after having been exposed to sunlight or covered with dust.
When comparing suppliers, don’t focus only on price.
Instead, evaluate:
· Engineering experience
· Weather resistance certifications
· Cabinet design
· Thermal management
· Manufacturing quality
· After-sales support
· Spare parts availability
· Installation guidance
When choosing a supplier for outdoor digital signage it is often best to go with a manufacturer with lots of experience. Shenzhen Longcheng Photoelectric Technology Co., Ltd. has over 20 years of experience designing modular outdoor LED display systems for advertising, transportation, sports venues and smart city projects worldwide. Experience not only means that a supplier can provide for different climate conditions and applications, but also that the displays can be properly specified for the installation environment.
We design our outdoor LED advertising screens to withstand extreme weather, to manage heat, to withstand impacts, to absorb power surges, and to resist corrosion so they can reliably operate in the toughest of environments.
Rather than focusing only on price, buyers should evaluate technical specifications such as IP rating, operating temperature, cabinet construction, certifications, and maintenance requirements. Choosing a display designed for local environmental conditions is the key to achieving long service life and stable performance.
A quality outdoor LED screen can last up to 80,000 to 100,000 hours depending on usage, installation and regular maintenance.
Yes. We design Displays to operate in a variety of environments, including environments subject to moisture and/or dust, by incorporating such features as anti-corrosion coatings, a completely sealed cabinet and other features that protect the Display from moisture and/or dust.
For most outdoor advertising applications an IP rating of IP65 or above is recommended, however applications in harsher environments may require an IP rating of IP66 or above.
Some of the main points to consider when choosing a display are: IP rating, brightness, operating temperature, cabinet material, refresh rate, serviceability, certifications, warranty and manufacturer support.
Most outdoor LED displays require around 5,000–7,000 nits for general visibility in direct sunlight, and more for higher specification displays.
