Because P3 and P4 are not particularly large in point spacing, many customers will use them as P3 P4 LED wall. However, many customers have difficulty distinguishing the difference between the two. Let’s take a look at them together.
Basic information of P3 LED display
The P3 indoor full-color LED display adopts the packaging method of SMD surface mount 2121 lamp beads (black light full-color) three-in-one, mainly composed of three colors of red, green and blue;
the resolution of one square meter is 111111 pixels, and the analog The group resolution is 64*64=4096 points, the point spacing between each pixel point is 3mm; the scanning method is 16 scans;
the power consumption per square meter is about 1300 watts per square meter, and the P3 full-color display cabinet Ultra-thin and ultra-designed, beautiful in appearance, easy to install, can be made into any shape according to the needs of users, easy to assemble and disassemble, and easy to maintain.
In different batches of customized products, LED boxes of the same specification are calibrated to the same brightness and color.
Basic information of P4 LED display
The P4 indoor display screen adopts the packaging method of SMD surface mount 2121 lamp beads (black light full color) three-in-one, mainly composed of three colors of red, green and blue;
the resolution of one square meter is 62,500 pixels, and the module resolution It is 64*64=2048 points, the point spacing between each pixel point is 4mm; the scanning method is 16 scans, the power consumption per square meter is about 500 watts per square meter, and high-quality light-emitting components are used for the display screen The core material and the use of its own patented circuit board design fundamentally ensure the service life of the product.
The kit design controls the splicing error between modules within plus or minus 0.1mm, which is easy to install and can be made according to user needs. Arbitrary shape, assembly and disassembly, easy maintenance.
From the above information, in fact, we can already detect the difference between the two. To sum up, the main points are as follows:
different pixel pitch
Because the dot pitch of P4 is 4 mm, and the dot pitch of P3 is 3 mm, the difference between the two is 1 mm. In reality, the difference is 1 mm, basically not many people will pay attention, but the LED display is required Using LED modules for splicing.
The number of lamp beads contained in different LED modules is not the same, and the gap is even bigger after splicing into a whole screen. This is a bit like, although 1 cent is inconspicuous, but if there are more than 7 billion people, 1 person gives 1 Dime, then there are more than 70 million, this money is a huge sum of money no matter where it is placed.
According to the actual test data, the pixel pitch of the LED display P3 is 3mm, one square meter contains 111111 pixels, the P4 pixel pitch is 4mm, and one square meter contains 62500 pixels. It means that although the difference is only 1 mm, after 1 square meter, the difference between the two is 48611 points.
Each point is not illusory, but actually corresponds to a lamp bead. The extra 48,611 points means an additional 48,611 lamp beads, which undoubtedly increases a lot of costs, and these costs will eventually be flattened. Spread it on the customer’s head. This is the main reason why the P3 LED video wall is more expensive than the P4 LED video wall.
The clarity is the same as when we zoom in on the picture. If we put a picture very large in PS, there will be obvious small squares. The LED display is very similar to this. When we use the P3 LED display, if When you walk to a distance of 2 meters or 1 meter, you will see more obvious small squares.
When we walk a little further, the square will slowly disappear and become a clear and normal picture.
If we look at P4 at the distance of P3, we will find that the clarity of P4 is not as good as P3, so there is a reason why P3 LED display is more expensive.
different viewing distances
In the range of less than and 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 will be better. If it is more than 30 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.
The smaller the dot pitch, the more suitable for close-up viewing. If the distance is too far, it is more suitable to choose LED display products with large dot pitch. Because the smaller the dot pitch of the LED display, the difficulty of production and processing will be corresponding. increase, the price will be higher. 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;
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 is slightly larger, and the module of P3 is smaller. From the use of In the above, larger modules can reduce the gap between modules, improve the flatness of the screen, and make the display effect more natural.
Different application scenarios
The application scenarios of led screens are different. P3 LED display screens can be used indoors, large lecture halls, large banquet halls and other occasions due to the small dot spacing. P4 led screens are used indoors and outdoors. Indoor P4 led displays are mainly used for performance stages, rentals and other occasions where the viewing distance is relatively far, and outdoor P4 displays are mainly used in squares, stadiums and other occasions.
