How to choose the right LED wall display model:
1. First, it should be clear whether it is an indoor LED or outdoor display. Indoor LED screens are not waterproof, and outdoor large screens are waterproof.
2. How big a display screen should be made, that is, how long and how high the electronic screen is.
3. Measure the viewing distance again, that is, how many meters the closest and farthest viewing distances from the display screen are.
With the above three data, you can roughly know what kind of LED display screen meets the requirements.
For example,if you want to make a full-color LED display screen on the stage, you need to measure the distance from the installation position of the display screen to the first row of audience.
How to choose the model of LED electronic display screen?
Due to the comprehensive advantages of full-color LED display screens such as low price, low consumption, energy saving, high brightness, and excellent display effect,
the application demand for full-color LED electronic display screens in various large-scale outdoor media, advertising, stadiums, public transportation, concerts and other fields will continue to grow rapidly.
The choice of model should comprehensively consider various factors such as: the purpose of the screen, display ratio, playback content requirements, viewing distance, cost budget, etc.
Basic elements of LED screen wall
1. In the full-color LED display, P stands for:
P means the distance between any two pixels. For example: P4 is 4mm, P10 is 10mm, and the resolution and clarity are different when the dot pitch is different. The smaller the dot pitch, the higher the resolution and clarity, so the smaller the dot pitch, the higher the price.
2. The pixel density per square meter is different when the dot pitch is different.
P3 has 111111 pixels per square meter, P4 has 62500 pixels per square meter, P5 has 40000 pixels per square meter, P6 has 27777 pixels per square meter, P7.62 has 17222 pixels per square meter, P8 has 15625 pixels per square meter, and P10- square meter is 10000 pixels.
3. The dot pitch is different, and the suitable viewing distance is also different.
For example, P3 is better when viewed from 3 meters away, P4 is suitable for viewing from 4 meters away, and so on.
P10 is suitable for viewing from 10 meters away; if the screen area is too small, a higher density LED display model is required to achieve a good display effect.
“How to choose the model of LED display screen with clear effect”
It is not that the display screen with denser dots is necessarily the most cost-effective and most suitable for you.
You can consider it according to the size of the area and the viewing distance requirements. Here are some examples of indoor LED display screen models:
P0.8, P0.9, P1.0, P1.25, P1.33, P1.5, P1.53, P1.667, P1.875, P1.9 are indoor small-pitch LED display screen models, which are often used in indoor places of government, institutions, and public institutions (such as video conferencing, monitoring centers, command centers, studios, etc.).
They require clear viewing at close range. These three models have high pixels and relatively high costs.
P2, P2.5, P3, belong to indoor high-definition LED display models, commonly used in conference rooms, lecture halls, exhibition halls, projections, corridors, etc.
Suitable for viewing distances of 3 meters, and the area is suitable for more than 4 square meters.
P4 and P5 are often used in hotel banquet halls and stage background LED large screens.
They can be used as temporary stage construction and LED stage large screens for performances and activities.
In order to facilitate carrying and transportation, they can be freely disassembled and assembled into boxes, which can be spliced in any size according to the venue environment.
Generally, there are iron boxes and aluminum boxes, and they are also equipped with aviation boxes for packaging and transportation.
What is the relationship between the resolution and model of LED display:
What is the resolution of LED display?
The horizontal pixel count of LED display multiplied by the vertical pixel count is the screen resolution. In fact, you can understand it as the precision of the screen image, which refers to the number of pixels the display has.
Since the points, lines and surfaces on the screen are composed of pixels, the more pixels the display can display, the finer the picture,
and the more information can be displayed in the same screen area, so resolution is one of the very important performance indicators.
If you imagine the entire image as a large chessboard, the resolution is expressed as the number of intersections of all warps and knots. To put it more directly, it is the number of LED display lights.
The higher the resolution of the screen, the more content can be displayed and the more delicate the picture is.
However, the higher the resolution, the more expensive it is.
It is also worth noting that for full-color LED display pixels, LED indoor screens have more pixels than outdoor screens, so the resolution is also higher.
So what is the relationship between the resolution and model of LED display screens?
Here is an indoor LED display screen for illustration:
Common models include P2, P3, P4, P5, P6, P8, P10. The number after P here represents the dot spacing, and the unit is mm.
For example, the dot spacing of P2 is 2mm, the dot spacing of P3 is 3mm, and the dot spacing of P4 is 4mm.
The smaller the dot spacing, the higher the pixel per unit area, the more LED lights, the higher the resolution, and the clearer the display effect.
Therefore, the unit area resolution is: P2>P2.5>P3>P4>P5>P6>P7.62>P8>P10.
Determinants of the clarity of full-color LED display screens:
1. Pixels:
Because they are all indoor surface-mounted technologies, both models are red, green and blue three-in-one. The dot pitch is the basis for distinguishing LED display screen models, and also determines the final display effect of the LED display screen.
2. Screen brightness:
Indoor surface-mounted technologies are all constant scanning, and the brightness requirement is generally above 600CD/m. In semi-outdoors, or indoor window positions, you must choose a model with a brightness greater than 3000CD/m or even higher.
3. Viewing distance and effect:
In the past, the background large screens used for stages, venues and various activities were generally P5 or coarser models.
Generally, viewers can see the picture clearly at about 10M, but if they take two steps closer, the screen will be full of granular dots.
Nowadays, various performing arts are developing rapidly, and indoor LED display screens generally use P2.5 and P3 models, and P2 for high definition.
Screen types for different scenarios
Banquet hall/multi-function hall LED display
The main function of the banquet hall LED display is the wedding background.
If the wedding LED large screen is a detachable rental screen, it is recommended to use P3.91 or P4.81 full-color screen.
The single size of these two screens is 500mm*500mm or 500mm*1000mm, and the disassembly and assembly are very simple and quick.
If the display is stage-fixed, you can choose P3 or P4 full-color display. The specific installation area varies greatly due to the size of the banquet hall.
A small banquet hall may only install a display of more than 10 square meters, but the LED display of a super-large banquet hall sometimes exceeds 80 square meters.
Video conference small-pitch LED ultra-high-definition 4K display
The traditional monitoring and security industry generally uses LCD screens, and splices large screens with non-standard LCD screens such as 65 inches and 42 inches.
The early LED display screens were not accurate enough to meet the requirements of video monitoring.
However, all this will gradually reverse with the rise of small-pitch LED displays. The market already has some ultra-high-definition displays with a pitch of 1.2mm, and even some products with a pitch of less than 1mm.
At present, the commonly used relatively stable small-pitch display screens are mainly P1.25, P1.53, P1.6, and P1.8. The size of a single conventional small-pitch LED screen is 320mm*160mm.
It adopts a one-time die-cast aluminum box, which is very convenient to install and maintain.
Lecture Hall/Auditorium Stage LED Display
In this multimedia era, the education industry has also kept pace with the times.
The appearance of LED display screens in school lecture halls or auditoriums proves this.
The area of the large LED screen for the stage background of the auditorium is generally between 30 and more than 100 square meters, and the models are mainly P2, P2.5, P3, and P4.
Exhibition Hall/Planning Hall LED Display
The exhibition hall is an important place for the company to show itself, and the full-color LED display screen is the finishing touch of the exhibition hall.
The LED large screen can fully display the core content of the company through multimedia files such as text, images, and videos.
The main models of the exhibition hall LED color screen are P1.25, P1.53, P1.86, P2.0, P2.5, and the specific size depends on the size of the exhibition hall.
The recommended display screen area is 20-50 square meters.
LED full-color display screen at the reception hall
The front desk is the face of an enterprise or institution, and its importance is self-evident.
The LED full-color display screen can fully show the first impression of the enterprise, and the reception hall is also a gathering place for indoor LED screens.
Usually, the viewing distance of the LED large screen at the reception hall is about 3-10 meters, so the display screen models are mostly P2.5 and P3, but the display area will not be too large, which is mainly limited to the small reception area.
From previous installation cases, the area of this type of LED color screen is 8-15 square meters.
