In the world of يعرض الصمام, the choice of size always seems to be closely tied to the visual experience.
We often hear the question: If the size of the LED display is reduced, does it mean that its مساحة وحدة الصورة must also be reduced? This article will take you to explore this question and analyze the subtle relationship between the size of the LED display and the pixel pitch.
1. What is the relationship between the size of the LED display and the pixel pitch?
How big is your big TV at home? Does it have a clear length and width? The same is true for LED displays. It has its own physical size, just like the size of the TV screen, but we usually measure it in millimeters or inches. For example, an LED display may be 320 mm wide and 160 mm high, which is its physical size.
Now, let’s take a look at the small dots on the LED display. These dots are pixels. The pixel pitch is the distance between these dots. If you stand far away and look at a painting, do the dots on the painting look closer?
This is what a small pixel pitch means. If the distance between the dots is large, then the مساحة وحدة الصورة is large. We usually use P to represent the pixel pitch, such as P20 and P10. The smaller the number, the closer the dots are, and the clearer the picture is.
So, what is the relationship between the size of the LED display and the pixel pitch?
In fact, there is no direct mathematical relationship between them. However, when we choose LED displays, we will determine their size and pixel pitch based on the usage scenario and needs.
For example, if you want a display with a very clear picture, then you may choose a small-sized display with a small pixel pitch. In this way, each pixel will be closer, and the picture will be more delicate.
However, if you just want a display for advertising, then you may not need such high clarity, so you can choose a large-sized display with a larger pixel pitch. In this way, although the picture is not so delicate, the effect is still good when the viewing distance is farther, and the cost is lower.
Therefore, the relationship between the size and pixel pitch of the LED display depends more on our usage needs and scenarios. I hope that this explanation will help you understand the relationship between them better!
2. The impact of the reduction in the size of the LED display on the pixel pitch is mainly reflected in the following two aspects
1). Increased pixel density
When the size of an LED display is reduced, in order to maintain the clarity of the image, the pixel density needs to be increased accordingly. Pixel density refers to the number of pixels per unit area, usually expressed in dots per inch (PPI).
When the size of the display is reduced, if the number of pixels remains the same or does not increase enough, the area occupied by each pixel will increase, causing the image to become blurred.
Therefore, in order to maintain the clarity of the image, the pixel density must be increased. That is, the number of pixels per unit area must be increased. This usually means using smaller LED lamp beads and denser pixel arrangements.
2). Changes in visual experience
The reduction in the size of LED displays also has a significant impact on the audience’s visual experience, which is mainly reflected in two aspects: viewing distance and viewing angle:
As the size of the display decreases, the audience needs to watch closer to get a clear visual effect. This is because when the size of the display decreases, the distance between pixels (i.e., pixel pitch) may decrease, but its impact may not be obvious relative to the audience’s viewing distance.
Therefore, in order to ensure that the audience can clearly see the content on the display, the viewing distance needs to be shortened. However, this also brings a problem, as too close a viewing distance may cause eye fatigue or discomfort to the audience.
The viewing angle refers to the maximum angle at which the audience can see the content of the display screen from different directions. As the size of the display screen decreases, its viewing angle may be affected to a certain extent.
On the one hand, it may be more difficult for a small-sized display screen to accommodate a large number of pixels, thereby limiting its resolution and clarity; on the other hand, it may be more difficult for a small-sized display screen to maintain consistent brightness and color uniformity, thus affecting the audience’s visual experience.
Therefore, when choosing a small-sized LED display screen, special attention should be paid to its viewing angle performance to ensure that the audience can get good visual effects from different angles.
Therefore, the impact of the reduction in the size of the LED display screen on the pixel pitch is mainly reflected in the increase in pixel density and the change in visual experience.
In order to obtain better visual effects, it is necessary to use smaller-sized LED lamp beads and denser pixel arrangements while reducing the size and paying attention to optimizing the viewing angle performance of the display screen.
3. Which pixel pitches are more suitable for small-sized LED displays?
When we talk about small-sized LED displays, choosing the right pixel pitch is the key to ensuring image clarity and audience visual experience. Pixel pitch, in simple terms, is the distance between two adjacent pixels on the display.
It is usually expressed in millimeters, and the smaller this number is, the denser the pixels are, and the more delicate the display effect is.
In the market, we can find LED displays with a variety of pixel pitches, but for small-size screens, the following pixel pitches are more common and more suitable:
- 9 to P1.5 mm:
These very small pixel pitches mean that the pixels on the screen are very dense, so they can provide very high resolution and very delicate display effects.
When you stand very close to the screen (such as 2 to 5 meters), these pixel pitches ensure that the images you see are very clear and rich in detail. They are very suitable for occasions that require close viewing, such as high-end conference rooms, monitoring centers, etc.
- 6 to P2.5 mm:
When the viewing distance is slightly farther (such as 5 to 10 meters) or the screen size is subject to certain restrictions, these pixel pitches are also a good choice. While ensuring a certain clarity, they can reduce manufacturing costs and improve cost performance.
Displays with these pitches are suitable for various indoor application scenarios, such as معرض displays, shopping mall advertisements, منصة backgrounds, etc. Although their resolution is not as high as P0.9 to P1.5 mm, they can still provide satisfactory display effects in most indoor environments.
3. How do you choose the pixel pitch for small-size LED displays?
When choosing the pixel pitch of a small-size LED display, you need to consider multiple factors, including viewing distance, application scenarios, resolution requirements, and budget. Here are some specific suggestions to help you make the right choice:
1). Consider viewing distance
- Close-up viewing:
If the audience needs to watch the LED display at a close distance (such as conference rooms, monitoring centers, etc.), a smaller pixel pitch should be selected, such as P1.0, P1.25 or P1.5, etc., to ensure the clarity and detail of the image.
- Medium- and long-distance viewing:
If the audience usually stands at a longer distance to watch (such as shopping mall advertisements, exhibition displays, etc.), you can choose a slightly larger pixel pitch, such as P2.0, P2.5, etc., which can reduce costs and maintain good visual effects.
2). Consider the application scenario
- High-end display requirements:
For application scenarios that need to display high-quality images, videos, or texts (such as high-end conference rooms, film and television production, etc.), a smaller pixel pitch should be selected to provide higher resolution and more delicate display effects.
- Ordinary display requirements:
For general commercial advertisements, stage backgrounds and other application scenarios, a slightly larger pixel pitch can be selected to meet basic display requirements and reduce costs.
3). Consider دقة requirements
- High-resolution requirements:
If you want to display high-resolution images or videos on a small-sized LED display, you should choose a smaller pixel pitch to provide more pixels to increase resolution.
- Low-resolution requirements:
If you only need to display simple text, icons, or low-resolution images, you can choose a slightly larger pixel pitch to reduce manufacturing costs.
4). Consider the budget
- الميزانية الكافية:
If the budget is sufficient and there are high requirements for display effects, you can choose a smaller pixel pitch to get a better visual experience.
- Limited budget:
If the budget is limited and the display effect is not high, you can choose a slightly larger pixel pitch to reduce costs.
5). Comprehensively consider other factors
- حجم الشاشة:
In the case of a small screen size, in order to maintain the clarity of the image, it is usually necessary to choose a smaller pixel pitch. But you should also consider the balance between screen size and pixel pitch to avoid the situation where the pixels are too dense or too sparse.
- زاوية الرؤية:
If the audience needs to watch the LED display from different angles, you should choose a product with a large viewing angle and good color consistency to ensure that the audience can get good visual effects at different positions.
خاتمة
In summary, the relationship between the size of the LED display and its pixel pitch is not static. Although, in many cases, a smaller display may mean a smaller pixel pitch to maintain the clarity of the image, the actual situation is far more complicated than this.
Technological advances, cost considerations, and changes in user needs are all important factors that affect this relationship.
