Introduction
Affichage LED is an efficient display tool and has been widely used in various places in people’s lives. As one of the most core technical parameters of LED display, dot pitch directly determines the resolution, viewing effect and manufacturing cost of the display.
So, how to accurately choose the dot pitch of the LED display that suits you has become a very important thing.
1. Why do you need to find a suitable dot pitch?
- First of all, the dot pitch directly affects the display effect.
Think about it: if the dot pitch is small, there will be more pixels per unit area, and the picture will naturally be delicate and clear. Just like when we look at the screen of a mobile phone, with high résolution, it is very clear to watch photos and videos, and it is comfortable for the eyes.
The same is true for LED display screens. Small dot pitches are suitable for close viewing, such as conference rooms and exposition halls, where details can be fully displayed.
- Let’s talk about the distance de visualisation.
The dot pitch is large, which is suitable for long-distance viewing. Think about it, we can see the content of the large outdoor billboards clearly from a long distance, and this is because the dot pitch is selected appropriately.
If you choose a small dot pitch, it will be blurry when you look at it from a distance, so how can it attract people?
- Of course, cost is also a consideration.
A small dot pitch means that more LED lamp beads are used, which is also troublesome to manufacture, and the price is naturally high. Therefore, when choosing the dot pitch, you have to weigh your wallet.
- Different occasions have different requirements for dot pitch.
If the indoor space is small and you watch more at close range, choose a small dot pitch; if the outdoor space is large and you watch more at a distance, choose a large dot pitch.
In addition, places like monitoring centres that need to see high-definition images must choose a small dot pitch; for places like large stadiums that need to cover a wide audience, a large dot pitch is more suitable.
In general, choosing the right dot pitch can make the LED display screen play the best effect on various occasions.
It is really a technical job to see clearly, watch comfortably, and consider the cost. However, as long as we choose according to our own needs, we will definitely find the most suitable dot pitch.
2. What are the key factors for determining the dot pitch of LED display screens for commercial needs?
1). Distance de visualisation
- Primary factor:
To be honest, the first thing to consider when choosing the dot pitch of an LED display is the viewing distance. Whether the dot pitch is chosen correctly directly affects the audience’s feeling of watching the screen.
- How to calculate the viewing distance:
There is a simple formula. The best viewing distance is about 1000 times the dot pitch. For example, for a screen with a dot pitch of 2 mm, the best viewing distance is about 2 meters. Of course, this is just an approximation.
In reality, it depends on the screen brightness and contrast. As for the minimum viewing distance, you have to actually measure it or ask the manufacturer.
For example, If you are in a high-end retail store and customers are close to the screen, then choose a small dot pitch, such as P1.25 and P1.56, which have delicate pictures and are comfortable to watch.
But if it is an outdoor billboard, people are far away, then choose a large dot pitch, P6, P8, and P10, and the cost is lower.
2). Display content
Content determines dot pitch: What content is to be put on the screen, and there are also requirements for dot pitch. If the content is delicate and complex, you have to choose a small dot pitch.
Delicate images and videos: For example, if you want to put high-definition videos, fine pictures, or text with a lot of small characters, you have to choose a small dot pitch so that the picture is clear and the details can be seen.
Simple text and icons: But if you just put some big titles, simple icons, or the background is a large colour block, there is no need to choose such a small dot pitch. A larger one is fine and can save money.
3). Installation environment
Different indoor and outdoor: The choice of dot pitch is different for indoor and outdoor LED screens.
Environnement intérieur : The indoor space is small and people are close to the screen, so you have to choose a small dot pitch, which is comfortable to watch. In addition, the indoor requirements for screen luminosité and contrast are also high.
Environnement extérieur : The outdoor space is large and people are far away from the screen, so you can choose a large dot pitch, which is also low in cost. But outdoor screens also have to consider waterproofing and sun protection.
4). Budget considerations
- Dot pitch and cost:
The smaller the dot pitch, the more expensive the screen because more LED lamp beads are used, and the manufacturing process is also complicated.
- How to save money:
So when choosing the dot pitch, you have to think about the budget. Under the premise of satisfying the display effect, choose a cost-effective dot pitch. Don’t blindly pursue a small pitch, which will cost too much money and is not cost-effective.
You have to choose according to the situation, which can meet your needs and save money.
3. Steps to accurately choose the dot pitch of the LED display
1). Clarify business needs
Before choosing the dot pitch of LED display, you must first clarify your needs. For example, what content do you want to display, high-definition video or simple text?
How far will the audience be from the screen? Is the installation environment indoors or outdoors, and is the light good? These must be thought clearly, because these all affect the choice of dot pitch.
2). Collect market information
You have to go to the market to see the characteristics and prices of LED displays with different dot pitches.
For example, whether the résolution is high, whether the brightness is sufficient, whether the contrast is good, and whether the viewing angle is wide. Compare more, and you will have an idea in your mind.
3). Calculate the best dot pitch
There is an empirical formula that the best viewing distance is about 1000 times the dot pitch. Based on this, combined with your own viewing distance, you can calculate the approximate dot pitch range.
Of course, the minimum viewing distance must also be considered, which is related to the screen brightness and human eye resolution. Once you have calculated it, you will know what dot pitch is appropriate.
4). Evaluate display effect and cost
When choosing a dot pitch, you must consider both display effect and cost. A good display effect will attract more people, but the cost is also high. So you have to find a balance.
If conditions permit, you can look at samples or simulated demonstrations, which will be more intuitive and give you a better understanding.
5). Choose suppliers and products
When choosing a supplier, you must find one with good reputation and strong technology. In this way, the product quality is guaranteed and the follow-up service is also up to date. Then choose a suitable product according to your needs and budget.
Size, resolution, brightness, contrast, etc. must all be taken into consideration. Once you have chosen it, you can use it.
