Those familiar with LED displays know that the "P" in LED electronic displays stands for pixel pitch, referring to the center-to-center distance between two adjacent LED beads, also known as dot pitch. The number after the "P" indicates the pixel pitch.
For example, a P1.8 LED display has a pixel pitch of 1.8mm, a P4 LED display has a pixel pitch of 4mm, and a P5 LED display has a pixel pitch of 5mm. Lower pixel pitch results in a clearer display, but also increases the cost. Due to different manufacturers' design practices, P1.8 small-pitch LED displays are generally designed in two specifications: P1.875 and P1.86.
A P1.875 LED display has a pixel pitch of 1.875mm and a module size of 240*240mm; while a P1.86 LED display has a pixel pitch of 1.86mm and a module size of 320*160mm. Pixel pitch is one of the most important technical parameters of LED displays, directly affecting the display effect and viewing distance.
A smaller pixel pitch means more pixels per unit area of the display, thus increasing resolution and viewing distance. In short, a smaller pixel pitch allows viewers to view the screen more closely and achieve a higher resolution. But is a smaller pixel pitch always better? While a smaller pixel pitch does contribute to higher resolution, it also increases cost.
In a small-pitch display, a smaller pixel pitch means more pixels per unit area, resulting in higher cost. Therefore, when choosing a display, consider the target audience's distance and budget to select a suitable pixel pitch that achieves the desired effect. If your display is located in an environment where the target audience needs to be very close to the screen, such as at a viewing distance of 4 meters or more, a 4mm P4 display will suffice.
If your display is suspended high up, further from your target audience, such as in airport signage, a 5mm-6mm pixel pitch is a good choice.
For applications requiring high precision, such as security monitoring or aerospace, a small-pitch display with a pixel pitch of less than 2mm may be necessary.
What is the ideal viewing distance for a P1.8 LED full-color display screen? How is it calculated? Actually, there's no fixed formula for calculating the viewing distance of a P1.8 small-pitch LED display screen. However, environmental factors such as air quality and weather conditions significantly affect visibility. Choosing the appropriate LED pitch based on the viewing distance allows for better brightness control, saves budget, and avoids unnecessary waste. P1.8 LED display screen viewing distance: Minimum viewing distance: LED display screen viewing distance = pixel pitch (mm) × 1000 / 1000 Suitable viewing distance: LED display screen viewing distance = pixel pitch (mm) × 3000 / 1000 What is the ideal viewing distance for a P1.8 LED display screen? Based on the simple formula above, the ideal viewing distance for a P1.8 full-color LED display screen is 1.8 meters, and the suitable viewing distance is 6 meters.
Is a P1.86 LED ultra-high-definition screen seamlessly spliced? Will there be gaps after installation? Will the image be fragmented? What are the differences between it and an LCD screen? When discussing large display screens, especially LED screens, many people immediately compare them to LCD video walls. Many of our customers, including ourselves, ask this question when they first consult us: "What are the advantages of your LED screen compared to an LCD video wall? Is this a seamless splicing screen?" The main differences are as follows:
1. Seamless splicing: Traditional LCD and DLP video walls have noticeable seams, while LED displays, regardless of size, present a complete, uninterrupted image.
2. Ultra-thin installation: LED displays can be assembled using the smallest unit modules, keeping the overall screen thickness within ten centimeters.
3. Flexible manufacturing: Another advantage of LED displays is their versatility in manufacturing. For example, if you have a wall and want to fill it with an LED display, other large video wall products would be limited by size and other factors. LED screens, with their smaller unit sizes, are not limited by aspect ratio.
What aspect ratio is most suitable for the length and height of a P1.8 ultra-high-definition LED screen for optimal effect? In the display industry, 1080P, or 2K, has become mainstream, while 4K and 8K products are also emerging. Many television programs and video signals are produced using the 16:9 "golden ratio" standard (though 4:3 and 2:1 ratios also exist).
LED full-color screens are generally made according to a 16:9 ratio, which results in a better screen effect and prevents stretching and distortion when playing videos and images. Of course, if installation space is extremely limited, it's possible to deviate from this ratio and use the screen's resolution to create videos and images pixel-for-pixel. However, custom video production is more expensive.
