What is P3 P4 LED wall?

P3 P4 LED wall are more commonly used LED displays, because their spacing is relatively small, so many people use them as background walls or video walls. This can not only modify the background, but also watch as a TV. It can be said that It is very convenient. What is the difference between LED display P3 and P4? Which is better? Let’s talk about the difference between the two.

Before understanding the LED display, we first need to understand what the P in front of P3 and P4 means, so that when we encounter other different types of products, we can quickly respond to their problems.

If we are usually careful, we will find that all types of LED displays will form a phrase with P followed by a number followed by an LED display. It is roughly like this:

P+Num+”LED display”

For example, the P3 LED display or P4 LED display we mentioned above. Then on this basis, we will see more expansion of some phrases, such as “P3 full-color indoor LED display”, “P4 outdoor rental LED” display” and so on.

After splitting the phrases, some viewers must have guessed the secret between them. In fact, the P in the LED display P3 or P4 refers to the distance between the center points of the two lights (generally represents the pixel spacing) , and the number after P refers to the distance between two pixels, commonly known as the point spacing.

The smaller the value of the distance between two pixel points, the higher the unit pixel point, and the clearer the display screen. The smaller the dot pitch, the higher the pixel density, and the clearer the picture. However, the smaller the corresponding point spacing is, the closer the visual distance is. If it is viewed too far, the effect of the picture will gradually decrease.

At this point, we can already see that the pixels of P3 and P4 are different, so their sharpness can already be viewed at different distances. In this way, we can summarize the following differences:

p3 led module vs p4 led module

Let’s first look at the parameters of the two

Basic parameters of P3 LED display

  • Dot spacing: 3mm
  • Pixel density: 111111 points/㎡
  • Drive mode: 1/16 scan
  • Average power consumption: 580W
  • Best viewing distance: 3~30M

Basic parameters of P4 LED display

  • Dot spacing: 4mm
  • Pixel density: 62500 points/㎡
  • Drive mode: 1/8 scan
  • Average power consumption: 390W
  • Best viewing distance: 5~40M

The difference between the two

different number of pixels

Although in reality, a gap of 1 mm is irrelevant to us, but if it is more than 1 mm, the gap will gradually widen. This is a bit like, 1 cent does not seem much, but if more than 7 billion People, one person gave dime, then there are more than 70 million, this money is a huge sum of money no matter where it is placed.

In the LED industry, the difference of 1 mm in the internal structure is also huge. According to the actual test data, the pixel pitch of LED display P3 is 3 mm, one square meter contains 111111 pixels, P4 pixel pitch is 4 mm, and one pixel pitch is 4 mm. A square meter contains 62,500 pixels.

That is to say, although the difference is only 1 mm, the difference between the two is 48,611 points after 1 square meter. This undoubtedly increases a lot of costs, and these costs will eventually be shared with customers.

different clarity

The smaller the dot pitch of the LED display, the more difficult the production and processing will be, and the higher the price will be. Therefore, in the same type, the price of P3 is higher than that of P4. And the larger the dot spacing, the more suitable for long-distance viewing. Because the dot spacing is different, the price and lamp density of the two are also different;

different viewing distances

In the range of less than or equal to 10 meters, the display effect of P3 will be better than that of P4. In the range of more than 10 meters, the viewing effect of the two is not very obvious. If you pursue cost-effectiveness, you can choose P4, but if you use P3, the effect It will be better, if it is more than 20 meters, then it will be better to choose P4.

After our actual calculation, we know that the best viewing distance of p3 led display is 3 meters away. If you watch it within 3 meters, the picture will have some graininess. It is recommended to choose a display with a smaller dot pitch.

The best viewing distance of P4 led screen is 4 meters away, and the viewing distance of P4 is longer. If the viewing distance is within 4 meters, there will also be graininess. If the viewing distance is relatively far, you can choose P4, if the viewing distance is relatively short. Just use P3. If the viewing distance is very long and choose the P3 screen, it is likely to spend a lot of money, but the advantages of the P3 led display will not be exerted.

So when we choose a display, we must first measure the viewing distance. Avoid spending more money because the viewing distance is too far, but it does not achieve better results.

different mods

The size of a single module of the p3 led display is 192×192mm, and the size of a single module of the P4 led screen is 320×160mm. From the perspective of a single module, the module of P4 will be larger, and the module of P3 will be smaller. It is determined by their different point spacings. In terms of use, if a single module is larger, the gap between the modules can be reduced, the flatness of the screen can be improved, and the display effect can be guaranteed.

Different application scenarios

The application scenarios of led screens are different. P3 LED displays are mainly used in indoor, large lecture halls, large banquet halls and other occasions. The picture is clear and high in contrast. The led display is mainly used for performance stages, rental and other occasions with a relatively long viewing distance, and the outdoor P4 screen is mainly used in squares, stadiums and other occasions.
