介绍
You spent a lot of money to install a large LED screen, but always feel that “something is wrong”?
The picture is grainy, the eyes are tired after watching for a long time, and the customer still complains that it is unprofessional… It is very likely that the dot pitch is wrong!
Don’t think that “P” is just a parameter. There are big pits behind this small number. If you choose it wrong, not only will the effect be poor, but you may also spend more money in vain.

1. What is "LED display dot pitch"? Why is it so important?
The “dot pitch” of the LED display, in simple terms, is the distance between two adjacent pixels on the screen, usually expressed in millimeters (mm), such as P2 is 2 mm.
The smaller the number after this “P”, the denser the pixels, and the clearer and more delicate the picture looks.
The dot pitch has a great impact on the clarity and 观看距离 of the screen. The smaller the dot pitch, the more pixels per unit area, and the clearer the picture naturally.
For example, a P1.5 screen looks more delicate than a P4 screen. In terms of viewing distance, a screen with a small dot pitch is suitable for close viewing.
For example, in places like conference rooms, 展览 halls, and home theaters, the viewing distance is usually about 1,000 times the dot pitch.
Screens with large dot pitches, such as P4 to P10, are suitable for long-distance viewing, such as outdoor billboards, stadiums, etc., and the viewing distance can reach tens of meters.
In addition, dot pitch also directly affects price and energy consumption. The smaller the dot pitch, the more LED lamp beads on the screen, the higher the manufacturing difficulty and cost, and the price is naturally higher.
For example, the price of a P1.25 screen is much higher than that of a P4. At the same time, small-pitch screens have higher requirements for the control system, further increasing the cost.
In terms of energy consumption, screens with small dot pitches usually consume more power because of their large number of pixels and high brightness.
However, with the development of Mini LED and Micro LED technology, today’s small-pitch screens have made great improvements in energy saving.
In general, dot pitch is a very important indicator when choosing an LED display.
The specific dot pitch you choose depends on your budget, viewing distance, and actual needs, and comprehensive consideration can achieve the best effect.
2. Four common reasons for choosing the wrong dot pitch of the LED display
1). Only look at the price and choose a screen with too large a pitch
Many people think that LED screens look similar, so they simply choose a cheaper one, and end up buying P6, P8 or even larger pitches.
Although this type of screen is cheap, the pixels are too sparse, and it looks like a mosaic when viewed up close, and the picture is very rough.
Especially when used indoors or at close range, the details cannot be seen clearly, and the only choice is to replace the screen, which is more expensive.
2). It is obviously for close viewing, but a specification for long-distance viewing is selected
For example, in places such as conference rooms, exhibition halls, and 购物中心 windows, the audience is very close to the screen, but you choose a P6 or P8 screen, which is generally for outdoor long-distance viewing.
It is all “grainy” when viewed up close, and the words cannot be seen clearly, which is a particularly poor experience.
In this case, you should choose a small pitch such as P1.5, P2, or P2.5, so that the picture is delicate enough.
3). Indoor screens and outdoor screens are confused
室内屏风 和 outdoor screens are quite different. Outdoor screens have high brightness.
Are waterproof and dustproof, and are expensive; indoor screens have low brightness, are not waterproof, but are cheap.
If you use it indoors, but buy an outdoor screen, not only will you spend more money, but it may also be dazzling because of the high brightness.
On the contrary, if you use an indoor screen outdoors, the brightness is not enough, you can’t see it clearly during the day, and it is easy to break.
4). Being fooled by sales and not choosing according to actual needs
In order to make more money, some salespeople will deliberately recommend products that are high in profit but not suitable for you.
However, in order to make more money, some salespeople will deliberately recommend products that have higher profits but are not suitable for you.
For example, you originally only need a P4.81 indoor screen, but they insist on selling you a P1.25, and they talk a lot about it.
As a result, you spend a lot of money, but the effect may not be more suitable for your needs.
In general, when choosing an LED screen, don’t just look at the price, and don’t believe in sales.
First, figure out whether you are using it indoors or outdoors, how far the audience is from the screen, and how much the budget is, and then decide what dot pitch to choose.
Only in this way can you buy a product that is both suitable and cost-effective, and avoid wasting money.
3. What practical impacts may be caused by choosing the wrong dot pitch of the LED display?
1). Poor display effect and obvious graininess of the LED display
If you choose an LED display with a large dot pitch, the picture will look like a “large grain” mosaic, which is not clear at all.
For example, in a conference room, the leaders are very close to the screen, and the words on the LED display cannot be seen clearly, which is embarrassing.
This kind of LED display is used to display pictures or videos, but the details are all gone, and the audience will definitely be dissatisfied.
2). Visual fatigue and poor experience of close-range users
If the audience is very close to the LED display, but the dot pitch of the screen is too large.
The eyes have to work hard to distinguish those “large grains”, and they will definitely be tired after a long time.
For example, in an exhibition hall or shopping mall, customers originally wanted to take a good look at the content on the LED display.
But their eyes were tired, the experience was bad, and they might just leave.
3). Reduced return on investment, poor advertising/information dissemination effect
If the LED display is used for advertising or displaying information, the wrong dot pitch is selected.
And the audience cannot see the content clearly, then the advertising effect will definitely be greatly reduced.
For example, the LED display for outdoor advertising has a large dot pitch, and people far away can’t see the advertising content at all, wasting advertising fees.
If it is a corporate exhibition hall, customers can’t see the display content on the LED display clearly, then the investment money will be wasted.
4). User complaints and damaged brand image
If the audience or customers are not satisfied with the poor display effect of the LED display, there will definitely be complaints.
For example, the LED display in the shopping mall, customers think the picture is too rough, and they may complain directly to the mall, or even complain online.
In this way, the brand image will be affected, and others will think that your brand is unprofessional and can’t even make an LED display, and they may not be willing to come or cooperate in the future.
4. 5 Countermeasures after wrong selection
If you find that the dot pitch of the LED display is wrong, don’t panic; there is always a way to remedy it. Here are some practical countermeasures:
If the screen graininess is too obvious, the most direct way is to change the display module. However, this matter needs to be carefully calculated:
成本： You have to spend money to buy a new module to change it, and you have to ask someone to install and debug it. If the screen area is large, the cost is not low.
Feasibility: If the screen is still under warranty or the manufacturer has a discount, you can consider changing it. But if it has been used for a long time, or it is too expensive to change, you may have to find another way.
优点： After the change, the screen effect will definitely be improved.
缺点： It costs a lot of money, the construction time is long, and it may also affect normal use.
If changing the module is too troublesome, you can try to adjust the position of the audience or the angle of the screen:
Move back: Move the audience’s seat back a little, or hang the screen a little higher, so that the audience is farther away from the screen, and the graininess will not be so obvious.
Change the angle: Tilt the screen slightly so that the audience can see it from the side, which can sometimes reduce the graininess.
优点： No money, easy to operate.
缺点： If the venue is limited, it may not be possible to adjust.
If the screen’s dot pitch is too large and not suitable for close viewing, use it in another place:
Move it outdoors: For example, move the screen originally intended for use in the conference room to the outdoors as a billboard. When viewed from a distance, the graininess is not so obvious.
优点： No money, and the screen can still play its role.
缺点： The position and purpose of the screen must be replanned, which may not be very convenient.
If the hardware cannot be changed, start with the content:
Use high contrast: Try to use high-contrast images, such as black background and white text, red background and white text, which can make the text and images clearer.
Keep the picture simple: Avoid complex patterns and text, use large fonts or simple charts, which are easier for the audience to see.
优点： No money, simple operation, and good results.
缺点： Content display may be limited, and some complex information may not be displayed well.
If you really can’t solve it yourself, you can consult a professional LED display manufacturer or technician.
They may give some more professional suggestions based on the specific situation, such as adjusting the brightness and contrast of the screen or using special software to optimize the display effect.
In short, although it is troublesome to choose the wrong dot pitch, there is always a way to remedy it.
According to the actual situation, choose the most suitable countermeasures, try to make the screen look more pleasing to the eye, and don’t let it be wasted!
5. Determine whether it is worth "secondary investment" to replace the screen?
1). Continue to use or replace with a new one?
If your LED screen has an inappropriate dot pitch, first think about whether to continue to use it or bite the bullet and replace it with a new one.
If you continue to use it, the advantage is that you save money on buying a new screen.
But the problem is that the screen display effect is poor, and the audience is uncomfortable, and may think that your place is unprofessional.
If the screen is used in places like shopping malls or exhibition halls, the audience experience is not good, and they may not want to stay longer.
They may even complain. Moreover, the old screen may consume a lot of electricity, and the electricity bill is also a considerable expense. If it often breaks down, it is also troublesome to repair.
If you replace the new screen, although it will cost a lot of money at the beginning, the new screen has a good display effect, which can make the audience shine and improve the overall experience.
Moreover, most of the new screens are now more energy-efficient, and in the long run, the electricity bill can be saved a lot.
However, the cost of installation and debugging must be considered when replacing the new screen, and a professional team must be found to operate it, which is an additional expense.
2). Calculate the cost and depreciation
Before deciding whether to replace the screen, you have to do a good job of calculating. First, see how much it costs to replace the new screen, including procurement costs, installation and debugging costs, transportation costs, etc.
Then calculate the cost of continuing to use the old screen, such as maintenance costs, electricity costs, and possible repair costs.
If the old screen has been used for several years, you can also calculate its residual value through depreciation.
For example, the service life of the screen is 5 years, and it has been used for 2 years, then its residual value is about 60% of the original price.
Compare the service life and depreciation of the new screen to see which one is more cost-effective in the long run.
3). Partial replacement or splicing optimization?
If you don’t want to replace the entire screen, you can also consider partial replacement or splicing optimization. If only part of the screen has a poor display effect or is damaged.
You can only replace the display modules with problems, which will be much cheaper. However, after the replacement, you have to see whether the overall display effect can meet your requirements.
Splicing optimization is also a way. If the dot pitch of the screen is too large, you can put multiple small screens together to form a large screen.
But there is a problem with splicing. There may be gaps between the screens. Software optimization must be used to minimize the visual impact of these gaps.
4). Long-term planning and budget balance
You also have to consider the long-term use plan and the actual budget of the screen. If the screen is only used for a short period of time.
Such as a temporary event, it may be more appropriate to continue using the old screen to save some money.
But if the screen is used for a long time, such as a corporate exhibition hall or advertising screen, then replacing the screen may be more conducive to long-term development.
After all, a good display effect can attract more customers and enhance the brand image.
The actual budget is also critical. If the budget is limited, you can first consider some low-cost optimization solutions, such as adjusting the content display strategy to make the screen look more comfortable.
Or optimize the use environment of the screen to reduce the impact of external factors on the display effect.
6. Avoid stepping on the pit again! 3 core principles of dot pitch selection
1). Empirical formula for selecting dot pitch based on viewing distance
When choosing an LED screen, the most important thing is to see how far the audience is from the screen. There is a simple formula for reference:
The best viewing distance (meters) = dot pitch (mm) × 3~5. For example, for a P2 screen, the best viewing distance is about 6 meters to 10 meters.
If the audience is close, such as in a conference room or exhibition hall, you have to choose a screen with a small dot pitch, such as P1.2 or P1.5, so that the picture is delicate.
If the audience is far away, such as outdoor billboards, P6, P10, or even larger dot pitch is enough, and it can save some money.
2). Dot pitch recommendations for indoor and outdoor
2.1). Indoor environment:
The indoor light is softer, and the audience is closer to the screen, so the dot pitch should be smaller.
For example, in places such as conference rooms and 酒店 lobbies, it is recommended to choose a P1.2 to P2.5 screen. This way, the picture looks delicate, and the eyes will not be tired.
2.2). Outdoor environment:
The outdoor sunlight is very dazzling, and the audience is far away from the screen, so the dot pitch can be larger.
For example, in places such as outdoor billboards and 体育馆, P4 to P10 screens are more suitable.
If the distance is particularly far, such as billboards next to highways, even P16 and P20 screens can be used, which is low-cost and effective enough.
3). Reasonable dot pitch range for different purposes
3.1). Advertising LED screen:
If it is used for advertising, such as outdoor billboards, the audience is far away, and the dot pitch can be larger.
For example, screens from P6 to P10 can ensure that the content can be seen clearly from a distance, and the cost is relatively low.
If it is an indoor advertising screen, such as an advertising screen in a shopping mall, the audience is close to it, and it is recommended to choose a screen from P2 to P3, which has a clearer picture.
3.2). Demonstration LED screen:
For example, in places like conference rooms and exhibition halls, the audience is relatively close to the screen.
And some more complex charts, texts, etc., need to be displayed, so the dot pitch must be small.
It is recommended to choose a screen from P1.2 to P2.5, so that the details of the picture can be seen clearly.
3.3). Live broadcast LED screen:
If it is used to broadcast sports events, concerts and other content with more dynamic pictures, the dot pitch should not be too large.
It is recommended to choose a screen from P2 to P4, so that the picture is smooth and the audience will not feel grainy.
In short, the dot pitch of the LED screen must be determined according to the actual viewing distance, the use environment and purpose.
This can save money and ensure the display effect. Don’t make blind choices like before; otherwise, you will spend money in vain, and the effect will not be ideal!
七、结论
It is not terrible to choose the wrong pixel pitch. What is terrible is not knowing how to remedy it and how to avoid pitfalls in the future.
As long as the purpose, budget and viewing distance are clear, LED screens can be used with ease.
If you are still hesitating whether to change or how to choose, you might as well stop and ask someone who really knows the business, which is much better than using it!
