What is outdoor display?

With the development of the market economy, the application scope of LED display is also expanding. As a new generation of information dissemination tools, it has been widely used in various industries.

As an external visual electronic media of the computer, the LED large-screen display has powerful real-time dynamic data display and graphic display functions. Moreover, the use of LED light-emitting diodes has great advantages in terms of service life and power consumption.

As long as we look carefully, we will find that the LED display has penetrated into all aspects of us. For example, the information display we see when we drive out is made of the LED display. When we go to the store to buy things, we can also display it in the store We see the hanging LED display above, and when we enter a large shopping mall, we often see LED displays of different sizes in all corners of the shopping mall.

Although they are all called LED displays, they are actually different. We generally use less rain and sun, and use them indoors as indoor LED displays, while for outdoor use, we often need The LED display that experiences wind and rain is called outdoor LED display.

There is also a kind of semi-outdoor LED display between indoor and outdoor, which is called semi-outdoor LED display. Most of this type of display is used under the eaves, and it may be exposed to a little rain. Here we mainly focus on the relationship between outdoor LED display and outdoor LED display. The difference between indoor LED displays.

We have briefly introduced the difference between outdoor LED displays and indoor LED displays. Now let’s take a closer look at them.

The outdoor screen has the functions of water resistance (rain), direct sunlight, dust resistance, high temperature resistance, wind resistance, and lightning protection. This type of display is called a pure outdoor display.

There is also a type of display screen between indoor LED display and pure outdoor LED display, which is installed in strong light environments such as eaves, open halls, outdoor canopies or sunny roofs. High-brightness LED, and the display itself is not resistant to (rain) water, wind, and lightning strikes. This type of display is called a semi-outdoor display.

Depending on where it is placed, the brightness used will also be quite different. The luminous brightness of the indoor screen is several times to dozens of times lower than that of the pure outdoor screen; putting the indoor screen outdoors is like putting the TV outdoors. The same brightness is not enough.

Therefore, the outdoor display must use ultra-high-brightness LEDs, and in order to further improve the brightness and increase the viewing distance, multiple ultra-high-brightness LEDs are often encapsulated in one pixel, so under the same model, outdoor LED displays are often stronger than indoor ones. LED displays are more expensive. And the higher the brightness, the higher the price.

With the development of indoor LED displays, high-quality LED displays will be installed in outdoor environments with low ambient brightness on the basis of waterproof, windproof, and lightning protection, in order to reduce the corresponding costs.

Summary of the difference between outdoor and indoor full-color LED displays

Difference 1. Use environment

The indoor full-color LED display generally does not need to have waterproof and fireproof requirements due to the location of use, while the outdoor full-color LED display poses a challenge to the adaptability of the product in various environments due to the diversity of the use environment. The outdoor full-color LED display is a system produced by combining the results of research on the external environment and applying it to the preliminary design in the early stage and the maintenance and repair in the later stage.

Of course, indoor LED displays are not completely waterproof. Whether they are indoor or outdoor LED modules, their circuit boards are coated with three-proof paint, which can be used in some humid indoor environments on a certain basis. .

Difference 2. Brightness requirements

The strong outdoor light leads to higher brightness requirements for outdoor full-color LED displays. Outdoor full-color LED displays are generally placed in the sun and exposed to direct sunlight. If the brightness is not handled well, or if there is reflection, the viewing effect will be affected to a certain extent. The general indoor LED display is 1000CD-2000CD/㎡, while the brightness of outdoor LED display is usually 4000CD-6000CD/㎡

Difference 3, suitable for observation distance

The higher the pixel of the full-color LED display, the clearer the display and the larger the information capacity it can contain, so the closer the viewing distance is. The requirements for pixel density outdoors are not as high as indoors, because the observation is farther away, so the pixel density is low, and the point distance is larger than indoors.
