Which is better between p2.5led display and P3, P4 display

What do p2.5, P3 and P4 of LED display mean? Many non display industry friends are unfamiliar with this;
The value behind P is the distance between two pixels or lamps (in mm), so the distance between p2.5, P3 and P4 is 2.5mm, 3mm and 4mm respectively.
P2.5 LED display, P3 and P4 end with ultra-high resolution, high-definition image, strong visual impact and long visual distance, which ensures that the display can be seen in the far area of the stage or business district;
What kind of LED display is better?
Full color LED display p2.5, P3 and P4 which is better?
In the same area, p2.5 has more points than P3, and P3 has more points than P4. For example, in an area of 1 square meter, p2.5 has 160000 points, P3 has about 111111 points, and P4 has only 62500 points. The smaller the distance, the higher the pixels and the better the clarity of the picture.
P3 is more expensive than P4, but it doesn’t mean P4 is not good, because the larger the distance between points on the screen, the more suitable the viewing distance. Generally, there is a formula: the best viewing distance = point distance / (0.3 ~ 0.8), which is an approximate scale.
According to this formula, the suitable viewing distance of P4 LED display screen is 5-13m, and the effect will be very good in this scale, which is enough to meet the daily practice. Of course, if you choose p2.5, p3led display, the effect will be very good, but the cost will be higher.
P2.5 display, P3 full color display type:
The clarity is very good, the best viewing distance is 2-20 meters, the price is relatively high, the pixel / clarity / effect requirements are high, you can choose these two types.
P4 full color display is the most widely used type in the market, with a pixel density of 62500 points per square meter. The best viewing distance is 4-20 meters, and the price is superior to p2.5 and P3.
Specific selection of which specification LED display, should be based on the use of environment, budget and other aspects of comprehensive consideration which is better, more suitable!
