Do you own, or are you looking to buy, an LED screen? Understanding the role of viewing distance and pixels in your screen is essential. Besides, pixel pitch can directly impact how close you sit to the screen and still see a clear picture. Therefore, knowing these two parameters can help you make a good decision. In this post, I will discuss the LED screen viewing distance and pixel pitch in more detail.
What is pixel pitch?
It measures the distance between the centers of two adjacent pixels on a screen. We calculate the pixel pitch of a display in millimeters. We state the pixel pitch with a ‘P’ and a number. For example, we have a P10 display screen. P10 indicates that the display screen has a 10 mm pixel pitch. The pixel pitch number gives us the distance between the two adjacent LEDs. Furthermore, it provides the minimum space for the viewer to see the image.
Let me give you a simple rule to understand pixel pitch and resolution better. The lower the pixel pitch, the higher the resolution of the display screen. And as a result, the more precise the image will appear to the viewer. Thus, it is essential to consider the pixel pitch when selecting a display screen. It is also important because it will determine the optimal viewing distance.
If the pixel pitch is lower, the smallest viewing distance will be closer. There is a general rule for determining the viewing distance from pixel pitch. It is 2-3 times the pixel pitch in meters. For example, a display screen has a fine pixel pitch of 2. We can say it is a 2mm pixel pitch LED screen. The optimal viewing distance for this screen will be 4 meters away.
Similarly, the optimal viewing distance for a 10mm pixel pitch screen will be 20 meters. The pixel pitch affects both the viewing distance and the visual experience. Thus, selecting the LED screen with the appropriate pixel pitch for your needs is crucial. It helps us to ensure the best image quality for your viewers.
Isn’t this helpful knowledge before buying a display? Well, it is. Continue reading, and you will know why the pixel pitch is so important.
Why is pixel pitch important?
When selecting a display screen, the pixel pitch is an essential factor to consider. It specifies the distance between each pixel on a display screen. And it determines how far away a viewer needs to be to see the individual pixels. Generally speaking, the lower the pixel pitch, the closer the viewer needs to be to the screen. Conversely, a larger pixel pitch needs a longer viewing distance to see the entire image.
The most important thing about an LED display is its image quality. If the image quality is good, the display can serve its purpose correctly. For example, pixel pitch directly impacts the image quality of the display screen. If the pixel pitch is low, the image has smoother borders and finer details. But the viewer needs to stand closer to the display. On the other hand, if the pixel pitch is high, the viewer should be far away to enjoy good image quality.
There is a general rule of thumb for determining the pixel pitch and viewing distance. If the pixel pitch is low, the viewing distance will be less, and vice versa. Moreover, there is a similar rule for display pixel pitch and resolution. If the pixel pitch is low, the definition will be higher. Thus, a 2mm screen has a higher resolution and less viewing distance than a 10mm screen.
But hang on; there is one thing to consider here. You may think buying a low pixel pitch display will give you high resolution. But such displays are more expensive due to increased production costs and materials. At the same time, a higher pixel pitch display requires more difficult maintenance. Hence, I think it is essential to consider a balance between these parameters. This way, you can get the best you want within your budget. Now that we have understood the pixel pitch let us calculate the viewing distance.
How to estimate the optimal viewing distance based on pixel pitch?
There are two rules to determine the optimal viewing distance from the pixel pitch. We have already discussed one of these methods above. Generally, the optimal viewing distance is 2-3 times the pixel pitch of the display. For example, if the pixel pitch of the screen is 2, the best viewing distance can be 4-6 meters.
Below I make a form for your better understanding:
| Pixel pitch | Minimum viewing distance | Optimal viewing distance |
| 0.9 mm | 0.9 meter | 1.8-2.7 meters |
| 1.2 mm | 1.2 meter | 2.4-3.6 meters |
| 1.5 mm | 1.5 meters | 3-4.5 meters |
| 1.86 mm | 1.86 meters | 3.7-5.6 meters |
| 2.5 mm | 2.5 meters | 5-7.5 meters |
| 5 mm | 5 meters | 10-15 meters |
| 8 mm | 8 meters | 16-24 meters |
| 10 mm | 10 meters | 20-30 meters |
You should also consider the screen size when figuring out the viewing distance. Generally, the larger the LED video wall, the further away the viewing distance should be. Finally, You should also consider the lighting conditions into account. It is because this may affect the visibility of the LED screen.
What is the best pixel pitch for your project?
First, let me assure you there is no such thing as the best pixel pitch. You may think the small pixel pitch will give you a higher resolution. And in this way, you will provide greater image clarity on your display. Well, things are more complex than it seems here. Different display screens and installation conditions need different pixel pitches. You can find the optimal pixel pitch you need by looking at these parameters:
- Optimal viewing distance
- Size of the display screen
- Your budget
Pixel pitch and the optimal viewing distance:
It is of paramount importance to find the optimal viewing distance for your LED screen. Suppose you stand closer to the screen and notice you can see the pixels as clearly defined blocks. If you start moving back, you will reach a distance where the outlines of these blocks begin to blur. It is the distance where you cannot distinguish between the individual blocks. You will start to see a uniform production of content. This distance is the optimal viewing distance of your LED screen.
Small pixel pitches give you smaller optimal viewing distances. It means you can view the uniform content closer to the screen. Such pixel pitches are excellent for indoor use, especially for homes and offices. For example, you may have your LED screen closer to you at your home. Thus, it will require a closer optimal viewing distance and a smaller pixel pitch.
For outdoor use, display screens with higher pixel pitch are suitable. For example, in concerts and shows, there is a vast crowd. People are watching the content on the screen from a distance. Thus, it will require a longer optimal viewing distance.
Size of the display screen:
The pixel pitch also relates to the size of the display screen. We can understand this relation from a 4K LED solution example. For a 4K screen, its resolution is 3840 x 2160 pixels. Therefore, an LED display module with a 1.5mm pixel pitch has a higher pixel density. Thus, it can fit more pixels than a 3mm LED display module of the same physical size.
Moreover, it has more pixels per module to produce the 4K content. As a result, you need fewer modules to create a 4K display. From this, we know the small pitch can reduce the screen size as it requires fewer modules. It also helps to keep the physical requirements to a minimum.
Your budget:
Small pixel-pitch LED displays are more expensive. It is because they need more materials, diodes, and wiring. Moreover, such displays have higher production costs. At the same time, high pixel pitch displays are less expensive.
Ultimately, the best pixel pitch depends on the project’s specific needs and budget. But, it is essential to consider all these factors when determining the best pixel pitch. With the right pixel pitch, you can create an immersive experience for viewers. It will ensure that your LED display delivers the best possible viewing experience.
How to estimate optimal display size based on pixel pitch?
Pixel pitch also has an impact on the size of the display screen. So we need a larger display size for a higher pixel pitch. And for smaller pixel pitches, we need a small size display screen.
Here I would list examples of display sizes to get 1920 x 1080 pixels:
| Pixel pitch | Optimal display size |
| 1.9mm | 3.65 x 2.06 meters |
| 2.5mm | 4.8 x 2.7 meters |
| 3.0mm | 5.76 x 3.24 meters |
| 4.0mm | 7.68 x 4.32 meters |
How does pixel pitch affect the LED screen price?
The greater the number of display pixels is, the greater its cost. For example, we have an outdoor LED display, and viewers are 10 meters away. The pixel pitch of this display will be higher, but the number of pixels will be low. Hence, the cost of such a direct view LED screen will be less.
At the same time, the indoor display screen will have a smaller viewing distance. Therefore, the pixel pitch of this display will be lower, but the number of pixels will be higher. Hence, the cost of such LED screens will be higher.
The pixel pitch primarily determines the price of an LED screen. The lower the pixel pitch, the higher the screen resolution, and the higher the price tag. Lower pixel pitch screens are more expensive due to their higher resolution. But they are worth the investment if you want a great viewing experience. Higher pixel pitch screens are cheaper. But the viewing distance will be far away for a comfortable visual experience.
When choosing the right LED screen for your needs, pixel pitch is paramount. It will have a significant impact on the quality of your viewing experience.
Conclusion:
After reading this post, I hope you understand the pixel pitch’s role and importance. It is an essential parameter of any display screen. It helps us to determine the following critical parameters:
- Viewing distance
- Resolution
