افهم بسرعة الفرق بين شاشات العرض LED P4 وP8

مقدمة

Among many شاشات عرض LED, P4 and P8 are two common specifications, but their performance characteristics and application scenarios are unique.

This article aims to explore the main differences between P4 and P8 LED display screens in depth, to help readers better understand these two specifications of display screens, so as to make a more informed choice in practical applications.

Among many LED display screen specifications, what mysteries and differences are hidden behind these two seemingly simple numbers, P4 and P8? How do they affect our viewing experience?

This article will explain the difference between P4 and P8 in detail.

1. Definition of P4 and P8

In the construction of LED display screens, each tiny light-emitting unit, that is, LED pixel or LED lamp bead, is a basic element that constitutes the overall picture.

The pixel pitch is the standard used to quantify the distance between these basic elements. Specifically, it refers to the straight-line distance from the center of a pixel on the display screen to the center of the adjacent pixel, usually measured accurately in millimeters (mm).

Therefore, when we talk about P4 or P8 display screens, we are actually describing the closeness and fineness of the pixel layout of these two display screens.

Taking P4 and P8 as examples, the dot pitch of P4 is 4mm, and that of P8 is 8mm, and its pixel density is four times that of the latter. This means that on a display screen of the same size, P4 can display more pixels, thereby achieving a more delicate and realistic picture effect.

As an important technical parameter of LED display screens, dot pitch not only directly determines the pixel density of the display screen but also profoundly affects the clarity, fineness, and viewing experience of its picture.

2. Comparative analysis of P8 and P4 LED display screens

1). Comparison between indoor P8 LED display screen and P4 LED display screen

In fact, P8 is rarely used indoors. Due to the large dot pitch of P8 and its low pixel density, it is not suitable for indoor close-up viewing. Therefore, in indoor applications, we more often see LED display screens with a dot pitch of P5 and below. This means that in indoor scenes, there is actually no direct comparison between the P8 LED display screen and the P4 LED display screen.

2). Comparison between outdoor P8 LED display screen and P4 LED display screen

2.1). Brightness and contrast

  • Outdoor environment: Outdoor display screens need to deal with strong direct sunlight, so they must have sufficient brightness and contrast to ensure clear visibility of content.

  • P4 LED display screen: Due to the higher pixel density, more LED lamp beads can be carried in theory, which may achieve a higher brightness range and contrast, but the specific needs to be determined according to product design and actual configuration.

  • P8 LED display screen: Although the dot pitch is large, it can also maintain good display effects in outdoor environments by using high-brightness LED lamp beads and an optimized design.

2.2). Viewing distance

  • P8 LED display: more suitable for long-distance viewing, such as large outdoor billboards, large screens in stadiums, etc., the audience can still clearly see the display content at a longer distance.

  • P4 LED display: It can also be used outdoors, but it is more suitable for medium- and short-distance viewing scenes, such as close-range advertising displays in commercial streets, outdoor small stage backgrounds, etc.

2.3). Waterproof and dustproof

Both P8 and P4 LED displays must have good waterproof and dustproof performance in outdoor applications to meet stable operation under severe weather conditions.

This is usually marked by IP ratings, such as IP65, IP67, etc., to ensure that the display is not affected by rain, snow, dust, and other environments.

2.4). Price and cost

  • Outdoor P4 LED display: Due to its higher pixel density and stricter technical requirements, its price is usually higher than that of a P8 display, especially in large-size, high-resolution application scenarios.
