There is no better way to impact your audience than setting an outdoor LED displays of your brand or company. When choosing LED display module, we need to consider many factors besides high definition. This article will list 11 tips critical for you to choose an effective and functional outdoor LED display screen to gain new opportunities to raise your brand awareness and more benefits. Now, let’s get started!
1. Choosing SMD LED Display Modules
Nowadays, outdoor full color LED display is mainstream. We can believe this trend will last for a very long time because of their high brightness with 16.77 million colors showed and Continuous work for 24 hours. The technologies of LED outdoor full-color screen has been very mature, and the price is also reasonable. In general, SMD LED display modules can be your cost-effective choice!

2. The LED Display Surface Flatness
To prevent image distortion, the surface flatness of outdoor LED screen modules should be kept within ±1mm. If this index can not be achieved, view dead angle may be caused even see from a reasonable view angle when playing your advertisements.
3. The White Balance
When the proportion of three primary colors (red, green and blue) is 1:4.6:0.16, the purest white can be fulfilled. Therefore, you need to choose LED display modules with good white balance, otherwise the visual effect may weaken.
4. Choosing the Correct Brightness
Under normal circumstances, 4500 to 7500 nits is perfect for outdoor LED video wall modules to counter daylight, and 5500+ nits is ideal for displays to counter direct sunlight. Otherwise, it will be difficult to have clear images due to insufficient brightness. The brightness level of the LED lamp beads should be one of your most highlighted concerns.

5. Water Resistance
Inclement weather may cause dampness of outdoor LED display screen modules thus recurring dead light, serial lighting up or even worse – fail completely. That means, if you want your outdoor LED displays can work properly on rainy days, the ingress protection (IP) rating should reach IP65. Besides, the LED display modules must be encapsulated by glue, with waterproof boxes equipped with and waterproof rubber rings connecting them well. In areas with frequent rainy days and easy accumulation of rainwater, it is recommended to choose IP68 LED display modules. Generally speaking, normal operation under such conditions that temperature of -30-55 ° and humidity of 10%-90% should be allowed. Look for displays that have a proper IP rating against moisture.
6. Dust Prevention
If dust comes into the body case, the aging of products may happen. To prolong the life span, there should be a specific dust-proof design to against contaminant infiltration. Generally, the IP rating should be IP65.
7. Constant Temperature & Heat Dissipation
As we all know, outdoor LED displays often need to consume more power than indoor LED displays, so the demand for heat dissipation is greater. If heat can not be effectively dissipated, it is easy to cause short circuits and other problems. Also, LED outdoor display modules must resist the heat emitted by a total of three heat sources of solar radiation, air convection and electronic components. Therefore, when installing LED display modules, have it install in a ventilated environment and use tools such as fans and air conditioners to assist heat dissipation when necessary. Additionally, outdoor LED displays have recommended temperatures for optimal use, make sure you choose the right type by asking your suppliers.
8. Defending Against Typhoon and Earthquake
The surrounding environment of installation can be varied and risks can be unpredictable, earthquake and typhoons are typical of such irresistible risks. So LED display screens need to be designed and installed complying with corresponding standards of coping with such extreme conditions. Please note that shockproof function is vital to prevent outdoor LED screens collapse and cause personal injury.
9. Lighting Protection
If outdoor LED displays are hit by lightning, it will lead to devastating damage to the products. To ensure safe operation in any kind of weather, large LED panels must be equipped with lightning rods and other lightning protection equipment to avoid being damaged by lightning. For example, we can install a surge protection device in the distribution box then ground it.
10. Resistance of Electromagnetic Interference
The uncontrollability of the outdoor environment makes anti-electromagnetic interference especially important. For example, we can use shielding technologies for internal electrical components, which can prevent internal components and cables from interfering with signals, and also from external electromagnetic interference to LED display modules.
For ensuring good picture quality even in the open air, it is necessary to pay attention to antireflection because that can effectively improve visuality and resolution.
As LED display modules are not consumer electronics and require a long service life, there are many things for us to concern about when choosing. Therefore, low prices should not be the primary determinant for consumers when choosing LED display modules. All in all, an outdoor LED display which can satisfy the above needs and be durable can really benefit your business and save your money.
