When we are looking for a suitable LED screen to meet our needs, the optimal viewing distance is what we will definitely think of.
From indoor short-distance LED displays to outdoor advertising LED screens, the optimal viewing distance varies greatly in different usage scenarios.
Next, I will take you to explore the mystery of the visible distance of the LED display.
What is the viewing distance for LED screen?
Viewing distance refers to the distance between the viewer’s eyes and the LED display.
At this distance, the viewer can hardly perceive the pixels with the naked eye and can see clear content
This is the maximum distance at which our naked eyes can see a clear image. The maximum value is affected by many factors, and the best viewing distance also depends on these factors.
When discussing the viewing distance of LED displays, a minimum value is usually set.
It not only helps our viewing experience but also affects the purchase cost-effectiveness.
What factors affect the best viewing distance of the LED screen?
Now that we know what the optimal viewing distance is, we know that there are some characteristics that have a great impact on it.
درجة البكسل
The size of the درجة البكسل affects the optimal viewing distance.
The smaller the pixel pitch, the finer the image and the closer the optimal viewing distance; the larger the pixel pitch, the farther the viewer needs to stand for the image to appear clear and not blurry.
Resolution
The resolution affects the optimal viewing distance
High-resolution LED screens are clearer, show more details, and have more delicate effects.
The audience will not see pixels when watching at close range, which is especially suitable for close-range applications such as conference rooms and studios.
Installation height
The height of the installation location and the viewing angle will affect the optimal viewing distance
The higher the screen installation height, the farther the audience’s viewing distance will naturally be. Conversely, the closer it will be.
Application scenarios (indoor/outdoor)
The optimal viewing distance of indoor and outdoor LED screens is usually very different because their uses and the pixel pitch of the screen are quite different.
usually used for close viewing, such as exhibition halls, conference rooms, command centers, etc., requiring smaller pixel pitch (such as P1.2, P1.5).
such as billboards, traffic guidance screens, etc., the viewer is far away, and the pixel pitch requirement is relatively low (such as P4, P6, P10, etc.).
Classification of LED Displays
LED screens can be divided into outdoor LED display screens and indoor LED display screens according to the environment.
Outdoor LED display screen
Outdoor LED display screens have a large area, generally ranging from a few square meters to dozens or even hundreds of square meters, with a large dot pitch (mostly 2500~10000 pixels/square meter).
The luminous brightness is 5500~8500cd/square meter (different orientations, different brightness requirements), and can be used under direct sunlight.
The viewing distance is tens of meters away, and the screen has good wind, rain and lightning protection capabilities.
Due to the harsh outdoor environment, outdoor modules are required to have good waterproof performance. Generally, the LED module is put into the kit and then glued to achieve waterproof effect.
Due to the large outdoor viewing distance, the outdoor LED module has a higher luminous brightness.
Indoor LED display
The area of indoor LED display varies from a few square meters to more than ten square meters depending on the use environment.
Since it is used in indoor environments and the viewing distance is close, this type of display screen generally has a beautiful appearance design and a high pixel density (number of pixels per unit area).
The viewing angle is large, the color mixing distance is short, the weight is light, the density is high, and the luminous brightness cannot be too high.
LED screens can be divided into fixed screens and rental screens according to application scenarios.
Fixed LED screen
Fixed screen refers to the LED display screen installed in a designated location.
In normal use, it does not need to be disassembled or moved after installation, so it only needs to meet the environment and viewing requirements.
Rental LED screen
Rental LED screens are generally used in temporary performances, parties, exhibitions and other venues.
This type of LED display screen generally has the characteristics of frequent disassembly, high installation efficiency, and strong viewing immediacy.
Therefore, rental screens have good protection, easy installation structure, and convenient component disassembly.
The best viewing distance for indoor led screens, outdoor led screens and rental screens
As mentioned earlier, the optimal viewing distance for different usage scenarios is not the same.
The following are the best viewing distances for different scenes under normal circumstances.
- Indoor close-range scenes (P0.9, P1.2, P1.5)
The best distance is between2-5 meters.
- Mall/store display(P1.8、P2.5、P3.0)
Optimal viewing distance: 2-5 meters
- Outdoor advertising screen (P6, P8, P10)
Optimal viewing distance: 10 meters
- Stage performance/exhibition background screen (P3.9, P4.8, P5.0)
Optimal viewing distance 5–15 meters
Calculation of best distance of LED screen
Minimum visible distance: visible distance of LED screen = pixel pitch (mm) x1000/1000
Optimal visible distance: optimal viewing distance of LED screen = pixel pitch (mm) x3000/1000
Farthest viewing distance: farthest viewing distance of LED screen = screen height (m) x30 (times)
This visible distance is a reference data. The specific visible distance also needs to consider brightness. In actual projects, the distance should be adjusted according to the on-site conditions.
Conclusion
There are many factors that affect the optimal viewing distance of the LED screen. I can quickly calculate the optimal viewing distance through the formula.
Of course, we also need to consider many factors such as pixel pitch, resolution, installation method, usage scenario, etc. to obtain the best viewing experience.
