Introduction
As one of the key parameters of an LED display, pixel pitch directly affects the resolution, viewing effect, and cost of the display.
However, many people have a misunderstanding about the choice of pixel pitch for indoor LED displays, thinking that the smaller the pixel pitch, the better. In fact, the choice of pixel pitch is not like this. This article will explore the reason in detail.
1. A brief introduction to the pixel pitch of an LED display
Pixel pitch, commonly known as “dot pitch,” is actually the distance between the small lamp beads (that is, pixel points) on the LED display. Imagine that if these small lamp beads are compared to small candies, then the pixel pitch is the gap between the candies. The size of this gap is expressed in millimeters (mm). For example, P1.5 means that the distance between the lamp beads is 1.5 mm. Pixel pitch is an important indicator that determines the clarity of the display!
1). The impact of pixel pitch on LED displays
1.1). Resolution
- Influence principle:
The smaller the pixel pitch, just like you sprinkle more candies in one place, the higher the “sweetness” (that is, resolution) of this place. In other words, the more pixels there are on the display, the finer the image and the more details you can see.
- Example comparison:
For example, the P1.5 display has densely packed pixels, like a super fine cake, and you can see the pattern on it if you look closely. The P4 display has fewer pixels, like an ordinary cake, which is also delicious but not as fine.
1.2). Viewing distance
Influence principle:
The pixel pitch also determines the best distance for you to watch the display. Imagine if you are too close to a piece of candy; you may only see one candy at a time, but not the whole candy board.
Similarly, if the pixel pitch is too large, you will see individual pixels instead of a coherent image if you are too close to the display. Therefore, the smaller the pixel pitch, the closer you are to the display, the better.
- Actual experience:
For example, the P3 display can still be seen clearly when you stand 3 meters away. But if you switch to a P1 display, even if you stand about 1 meter away, the picture will still be clear, just like watching a super HD TV screen.
1.3). Visual effect
- Clarity:
The smaller the pixel pitch, the higher the clarity of the display; just like watching a high-definition movie, every detail is clear. This is very important for places that need to display high-definition quality, such as high-definition video conferencing, digital billboards, etc.
- Brightness and contrast:
Although the pixel pitch does not directly determine the brightness or contrast, you can imagine that if there are more candies on a candy board, will it look brighter and more vivid overall?
In the same way, the display with a small pixel pitch will have better overall brightness and contrast because of the large number of lamp beads, and the picture will look more vivid and attractive.
The smaller the pixel pitch, the clearer the picture and the brighter the color when you look at the display from different angles. This is like looking at a super HD TV screen from different angles; the picture will not be deformed or discolored.
This is very important for places where many people need to watch the display together, such as stadiums, large performances, etc.
1.4). Cost and price
- Influencing factors:
The smaller the pixel pitch, the harder it is to make, and the more materials and techniques are required, the more expensive the price. Just like if you make a super delicate cake, it will definitely take more time and effort than making an ordinary cake.
- Careful consideration:
Therefore, when choosing an LED display, you should choose the appropriate pixel pitch according to your needs and budget.
If you pursue high-definition picture quality and close-up viewing, then choose a small pixel pitch; if you just need to watch from a distance or the budget is limited, then choose a large pixel pitch.
2. Factors for selecting pixel pitch of indoor LED display
1). Viewing distance
- Close-up viewing:
When the audience is close to the display, such as indoor places such as conference rooms and exhibition halls, the clarity and details of the image are required to be higher.
At this time, an LED display with a smaller pixel pitch should be selected to ensure that the audience can clearly see the content on the screen.
A smaller pixel pitch means more pixels per unit area, thereby improving the resolution and clarity of the screen.
- Long-distance viewing:
If the audience is far away from the display, such as the atrium of a large shopping mall or a high-rise monitoring room, a display with a larger pixel pitch can be appropriately selected.
Because the larger pixel pitch can still maintain good visual effects when viewed from a distance, and the cost is relatively low.
1.1). Example
- Close-up viewing:
Assume that in an indoor conference room, the audience is about 2-3 meters away from the display. At this time, it would be more appropriate to choose a display with a pixel pitch of P1.5 or P1.86.
These pixel-pitch displays can provide high resolution and clarity, ensuring that the audience can clearly see the text and images on the screen.
- Long-distance viewing:
If in the atrium of a large shopping mall, the audience may be 10 meters or even farther away from the display.
At this time, it is sufficient to choose a display with a pixel pitch of P4 or P5. These pixel-pitch displays can still maintain good visual effects when viewed from a distance, and the cost is relatively low.
2). Application scenario
- Conference room:
Clear text, charts, and images are usually required in a conference room. Therefore, a display with a smaller pixel pitch should be selected to ensure that the audience can clearly see the content on the screen. Common pixel pitches are P1.25, P1.538, P1.86, etc.
- Exhibition hall:
Exhibition halls usually need to display high-resolution images and videos to attract the audience’s attention.
At this time, you should choose a display screen with a smaller pixel pitch, such as P1.5 or P1.86. These pixel-pitch displays can provide delicate pictures and rich colors, enhancing the attractiveness of the exhibition.
- Monitoring room:
In the monitoring room, it is usually necessary to monitor multiple screens in real-time. At this time, you should choose a display screen with a moderate pixel pitch and high resolution to ensure the clarity and details of the monitoring screen. Common pixel pitches are P2.5, P3, etc.
Choosing a suitable pixel pitch is crucial to improving display effects and user experience. If the pixel pitch is too large, it will cause image blur and loss of details.
If the pixel pitch is too small, although it can improve clarity, it will increase cost and technical difficulty. Therefore, when choosing pixel pitch, you should weigh it according to the needs of specific application scenarios.
3). Cost budget
- The smaller the pixel pitch, the higher the cost:
A smaller pixel pitch means more pixels per unit area, requiring more LED lamp beads and more sophisticated manufacturing processes.
Therefore, the production cost and technical difficulty will increase accordingly, resulting in a higher selling price.
- The larger the pixel pitch, the lower the cost:
A larger pixel pitch means fewer pixels per unit area, which will reduce production costs and technical difficulties accordingly, and the selling price will be relatively low.
When choosing pixel pitch, not only should the display effect and user experience be considered, but also cost-effectiveness should be considered. If the application scenario does not require a high pixel pitch, a larger pixel pitch can be selected to reduce costs.
If the application scenario requires a high pixel pitch but the budget is limited, you can consider choosing the most cost-effective pixel pitch solution while ensuring the display effect.
For example, in a conference room, if the budget is limited but the display effect and user experience need to be guaranteed, a display with a pixel pitch of P1.5 or P1.86 can be selected. These pixel-pitch displays can provide high resolution and clarity to meet the needs of the conference room, and the cost is relatively low.
In the exhibition hall, if the budget is sufficient, a display with a smaller pixel pitch can be selected to provide a more delicate picture and richer colors.
3. The reason why smaller is not better
When choosing the pixel pitch of an LED display, many people may think that smaller is better because a smaller pixel pitch usually means higher resolution and clearer images. However, in reality, the smaller the pixel pitch, the better. Here are a few key reasons:
1). Visual effect is not the only criterion
- Uneven brightness:
When the pixel pitch is too small, the arrangement between the LED lamp beads will be closer, which may cause more obvious brightness differences between the lamp beads, resulting in uneven brightness. This uneven brightness not only affects the viewing experience but also may cause eye fatigue.
- Moiré:
A pixel pitch that is too small may also cause moiré problems. Moiré is an interference pattern caused by the mismatch between the arrangement of screen pixels and camera or human eye pixels. It causes ripples or stripes in the image, seriously affecting the visual effect.
Although smaller pixel pitches usually mean higher resolution and clearer images, we must also consider practicality. A pixel pitch that is too small may cause the above problems, thereby affecting the overall performance and service life of the display.
Therefore, when choosing a pixel pitch, we need to find a balance between visual effects and practicality to ensure that the display can provide high-quality images while maintaining stable performance and reasonable costs.
2). Technical limitations and cost considerations
- Difficulty of implementation:
Too small a pixel pitch places higher requirements on manufacturing processes and technical levels. For example, a more precise arrangement of lamp beads, a more sophisticated circuit board design, and a more efficient heat dissipation system are required.
These technical requirements not only increase the difficulty of production but may also reduce production efficiency.
- Cost:
As the pixel pitch decreases, the production cost will also increase accordingly. Smaller lamp beads, more sophisticated manufacturing processes, and higher technical requirements will lead to rising costs.
Therefore, when choosing the pixel pitch, we must take into account the cost factor to ensure that the selected pixel pitch is technically feasible and economically reasonable.
When choosing the pixel pitch, we need to find the best balance between technology and cost. On the one hand, we must ensure that the selected pixel pitch can meet the application requirements and provide high-quality images and stable performance.
On the other hand, we must also consider the cost factor to ensure that the selected pixel pitch is economically feasible. By comprehensively considering the technical level and cost factors, we can choose the most suitable pixel pitch solution.
3). Diversity of market demand
Different markets have different requirements for the pixel pitch of LED displays.
For example, indoor conference rooms may require high-resolution, small-pixel pitch displays to display clear text and images, while outdoor billboards may pay more attention to brightness, weather resistance, and cost-effectiveness, so they may choose displays with larger pixel pitches.
In addition, different industries and different places have different requirements for the pixel pitch of the display screen.
Given the diversity of market demand, we need to customize solutions according to specific application scenarios and needs.
By deeply understanding the needs and expectations of customers, we can provide them with the most suitable pixel pitch solution to meet their specific needs. This customized solution can not only improve customer satisfaction but also enhance our market competitiveness.
In summary, when choosing the pixel pitch of the LED display, the smaller the better. We need to comprehensively consider multiple factors such as visual effects, practicality, technical level, cost, and market demand to find the most suitable pixel pitch solution.
4. How to choose the right pixel pitch
1). Clarify the needs
Before choosing the pixel pitch, we must first clarify several key needs:

The distance of the audience from the display screen directly affects the choice of pixel pitch. Close viewing requires a smaller pixel pitch to ensure a clear image, while long-distance viewing can choose a larger pixel pitch.
- Application scenarios:
Different application scenarios have different requirements for pixel pitch. For example, conference rooms require high resolution to display clear text and graphics, while outdoor billboards focus more on brightness and weather resistance.
- Cost budget:
The smaller the pixel pitch, the higher the cost. Therefore, when choosing a pixel pitch, you must consider the cost budget to ensure that the selected solution is economically feasible.
After clarifying these requirements, you can choose a suitable pixel pitch more specifically.
2). Consult professionals
The technology in the field of LED display screens is constantly developing, and new products and technologies are emerging in an endless stream.
Therefore, it is recommended that professionals or manufacturers in this field consult to obtain the latest product information and professional advice. They can recommend the most suitable pixel pitch solution for you based on your specific needs and budget.
When communicating with professionals, you can elaborate on your application scenarios, viewing distance, cost budget, and other requirements so that they can better understand your needs and provide targeted advice.
3). Comprehensive consideration
When choosing a pixel pitch, you cannot consider a single factor but need to consider multiple aspects comprehensively:
- Visual effect:
Pixel pitch directly affects the resolution and clarity of the display. Smaller pixel pitches can provide higher resolution and clearer images but may also cause problems such as uneven brightness or moiré.
- Technical feasibility:
Too small pixel pitches place higher requirements on manufacturing processes and technical levels. When choosing pixel pitch, it is necessary to consider whether the current technical level can be achieved and ensure the stability and reliability of the production process.
