When you buy an عرض الصمام, you will consider what kind of pixel spacing to choose. Among the many technical parameters of LED display, pixel spacing is a particularly important indicator. Pixel spacing not only directly determines the resolution and clarity of the display but also affects the audience’s viewing experience.
So, what is the pixel spacing of a small LED video? Do you know? This article will give you the answer to questions about the pixel spacing of LED displays.
1. The concept of LED display pixel spacing
The pixel spacing of the LED display is an important technical parameter that describes the fineness and clarity of the screen.
If you want to figure out the pixel spacing, first of all, we have to know what a pixel is. Pixels are the basic units that make up images. Just like the photos or videos we see are composed of countless small dots, which are pixels, each pixel on the LED display is actually composed of one or more LEDs (light-emitting diodes).
So, what is the pixel spacing? In short, it is the distance between the centers of two adjacent pixels. We can imagine that small squares are closely arranged together; each small square represents a pixel, and the pixel spacing is the distance between these small squares. This distance is usually expressed in millimeters (mm).
In addition, LED display suppliers also like to use P3 and P4. For example, the pixel spacing of 3mm is equal to P3, 3.9mm is equal to P3.9, and so on.
Because pixel spacing is directly related to the fineness and clarity of the picture we see, the smaller the pixel spacing, the more pixels can be accommodated per unit area, and the more details and color changes can be displayed in the picture, making it look clearer and more realistic. On the contrary, if the pixel spacing is large, the pixels on the picture will appear sparse, and the ability to express details will decline.
2. What does pixel spacing have to do with resolution?
Resolution is actually an indicator used to describe the total number of pixels that can be displayed on the screen. If the size of the screen remains fixed, the smaller the pixel spacing, the more pixels can be accommodated, and the higher the resolution.
Therefore, pixel spacing and resolution complement each other, and they jointly determine the image quality performance of the LED display.
In practical application, we need to choose the appropriate pixel spacing according to specific needs. For example, in shopping malls, conference rooms, and other indoor places, we usually choose LED displays with smaller pixel spacing to ensure that the audience can clearly see the content on the screen.
In outdoor billboards and other places, due to the distance between the audience, the display screen with a slightly larger pixel spacing can be appropriately selected, which can not only meet the viewing needs but also control the cost.
3. What is the impact of pixel spacing on the display of LED display?
Pixel spacing has a great impact on the LED display. In short, pixel spacing is the distance between two adjacent pixels on the screen. The smaller the distance, the denser the pixels on the screen, and the clearer and more delicate the image we see will be.
For example, suppose you have two screens, one with a large pixel spacing and one with a small pixel spacing. When you play the same high-definition video on these two screens, you will find that the picture on the screen with a small pixel spacing is clearer and more detailed. The picture on the screen with large pixel spacing may be blurred, and the details may not be so obvious.
In addition, pixel spacing will also affect the angle at which we watch the screen. The pixel spacing is small, and the picture seen from all angles is clearer. If the pixel spacing is large, you may need to see the content on the screen from a specific angle.
Therefore, when choosing the LED display, we should consider the viewing distance and scene. For example, in shopping malls or conference rooms, people are usually close to the screen, so it is suitable to choose a screen with a small pixel spacing.
On the large outdoor screen, because people are usually far away from the screen, they can choose a screen with a slightly larger pixel spacing.
4. How do you choose the pixel spacing of LED displays in different application scenarios?
When selecting the pixel spacing of the LED display, different application scenarios need to consider different factors. Pixel spacing directly affects the fineness and clarity of the picture, so it is necessary to weigh and choose according to factors such as viewing distance, scene characteristics, and budget.
First of all, for indoor application scenarios, such as shopping malls, conference rooms, etc., the audience is close to the screen and usually requires high picture quality and clarity.
In this case, it is recommended to choose an LED display with a smaller pixel spacing to present more delicate images and details. In this way, the audience can still feel the clarity and realism of the picture when watching up close.
Secondly, for outdoor application scenarios, such as billboards, large display screens, etc., the audience is far away, so you can choose a display with a slightly larger pixel spacing. This is because in the outdoor environment, the audience is far away from the screen, and the smaller pixel spacing may not be obvious for long-distance viewing.
Excessive pixel spacing will increase the cost and may lead to insufficient brightness, impaired picture quality, and other problems. Therefore, in outdoor applications, it is necessary to consider factors such as viewing distance, cost, and ambient brightness to choose the appropriate pixel spacing.
In addition, it is also necessary to consider the specific needs of application scenarios. For example, in large-scale event venues such as gymnasiums and concerts, the audience is widely distributed, and the viewing distance varies greatly.
In this case, a display screen with moderate pixel spacing can be selected, which can not only meet the picture quality requirements of the close audience but also ensure that the long-distance audience can see the basic content clearly.
In addition to application scenarios, the budget is also one of the factors to be considered when choosing pixel spacing. Displays with small pixel spacing are usually more expensive, while displays with large pixel spacing are relatively low.
Therefore, when selecting pixel spacing, it is necessary to weigh according to the actual budget and find the most cost-effective solution.
5. What is the development trend of pixel spacing?
The development trend of pixel spacing is moving in a smaller direction. With the continuous progress of LED display product technology, the pursuit of higher pixel density and smaller pixel spacing has become the main direction of the industry.
First of all, from the perspective of market demand, whether in the field of indoor or outdoor display, there is a strong demand for smaller pixel spacing products.
With the improvement of people’s requirements for image quality, the requirements for the fineness and clarity of the display picture are also increasing, which promotes the continuous reduction of pixel spacing.
Secondly, from the perspective of technological development, the emergence of new display technologies, such as COB (Chip-on-Board) packaging technology, provides technical support for the reduction of pixel spacing.
These new technologies not only improve the pixel density but also significantly improve the color performance, brightness, and contrast of the display screen.
In addition, with the reduction of production costs and the improvement of production efficiency, LED displays with smaller pixel spacing are expected to gradually enter the all-in-one machine market and the civilian market, further promoting the reduction of pixel spacing.
However, it should also be noted that the reduction of pixel spacing is not unlimited. In practical application, it is also necessary to consider the viewing distance, application scenario, cost, and other factors. Therefore, when choosing the pixel spacing, it is necessary to consider various factors and find the most suitable balance point.
