‘What is the relationship between LED display resolution and model number’
What is LED display resolution?
The number of horizontal pixel dots multiplied by the number of vertical pixel dots of the LED display is the screen resolution.
In fact, you can understand the precision of the screen image as the number of pixel points that the LED display has.
Since dots, lines and surfaces on a screen are made up of pixels, the more pixels a display can show, the finer the picture.
The more information that can be displayed in the same screen area, the more resolution is a very important performance indicator.
If you imagine the entire image as a large chessboard, and the resolution is represented by the number of all warp and knot intersections.
It is also the number of LED display beads.
The higher the resolution of the screen, the more content can be displayed and the more detailed the picture.
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 pixel points than outdoor screens, and thus higher resolution.
So what is the connection between the resolution and the model number of the LED display?
Here to indoor LED display as an illustration：
Common models are P2, P3, P4, P5, P6, P8, P10, where the number behind the P is expressed in point spacing, the unit is mm.
For example, P2 point spacing is 2mm, P3 point spacing is 3mm, P4 point spacing is 4mm.
The smaller the dot pitch, the higher the pixel points per unit area, the higher the number of LEDs, the higher the resolution and the clearer the display.
So the resolution per unit area：P2>P2.5>P3>P4>P5>P6>P7.62>P8>P10.
Elements that determine the clarity of full-color LED displays：
Because all are indoor surface paste technology, are red, green and blue three in one.
Point spacing is the basis of LED display model differentiation, but also determines the final display effect of the LED display.
Such as P4.81 model point spacing technology, single square 43,254 pixels resolution.
2. Brightness:
Table sticker technology belongs to the constant motion scanning, brightness requirements are generally 600CD / m or more.
In the semi-outdoor, or indoor window position must choose the brightness greater than 1000CD / m or even higher brightness model.
3. Viewing distance and effect:
P4.81 is the stage, venue and all kinds of activities used in the background of the big screen.
General viewing is located in about 10M, the picture is clear.
Nowadays, all kinds of performances are developing rapidly, indoor LED display screen is generally used P2.5 and P3 models, high-definition is P2.
When choosing display, we must consider the size, use demand, installation and viewing environment, budget to comprehensive consideration.
If the viewing position is not harsh, indoor full color LED display effect is difficult to distinguish, such as the above mentioned P2 and P2.5, but the finer the model the more expensive.
How should design LED display size and specification:
Whether it is an outdoor display or an indoor LED screen, their size varies greatly, the area of the large LED screen has hundreds of thousands of square meters, the small maybe only 3-4 square meters.
So what is the appropriate width to height ratio of LED display?
How to calculate the exact size of the display?
Now we often recommend LED screen ratio of 16:9 or 4:3 (not necessarily install this ratio to design, mainly to visit the installation location of the space size)
What can LED displays play display?
Many people feel that the LED screen is a TV, because it can play TV programs.
Some people feel that the LED screen is an advertising screen, because it often plays advertising images, text, and video.
Others feel that the LED screen is a stage background, because we can see it in all kinds of parties and concert stages.
And this also represents the basic function of the LED full-color display, simply put LED full-color display is a large display.
It can play such as pictures, text, audio and video files, but also can play cable TV programs, if there is a video processor, it can realize the live synchronous live broadcasting function (to show the live picture in real time).
LED full color display playback principle: LED color screen playback content is very rich, including video, images, text and other information.
So how does the display screen to play the display?
I believe that many people are very curious about this issue.
Currently there are two forms of LED screen playback.
One is synchronized control system, one is asynchronous control system.
At present the vast majority of displays use the former, synchronous display system has a sending card, receiving card.
The sender card is installed inside the video processor and the receiver card is installed on the back of the display.
The two are connected through a network cable, the sender card sends the playback content, the receiver card receives the information and plays it out on the display.
Many customers who buy LED displays do not have a clear concept of which LED display.
We should choose the right cost-effective LED products according to our own needs.

FAQ
1. Which type of LED display to choose for lecture hall/auditorium stage?
In this multimedia era, the auditorium stage background LED screen area is generally between 30-100 square meters, the model is mainly to P2, P2.5, P3, P4-based.
- How to choose the model of LED display with clear effect
LED display screen does not have the highest definition only more high-definition.
LED display clarity is based on the use of the environment, screen size, viewing distance to decide.
Display clarity are relative, for example, indoor P2.5 is clearer than P3, P3 is clearer than P4.
