Pixel pitch is the first factor we should consider when we’re about to purchase an LED display. Why? Because it defines at what distance an LED display offers optimal visual experience. That is to say, the viewing distance is an element restrained by the scene of an event. Simply put, deploying an LED display with the wrong pixel pitch will never yield good visual results. Now let’s dive into the world of pixel pitch, learn what it is, and explore how to decide the right pixel pitch for an event.
Pixel pitch decides the density of LEDs within a certain area.
Pixel pitch, also referred to as dot pitch, indicates the distance between the center of two adjacent pixels on an LED displays. Pixel pitch is calculated in millimeters and written in a format of letter P followed by numbers. For example,a P1.25 LED display has a pixel pitch of 1.25mm. So the distance between the center of adjacent pixels is 1.25mm.
Pixel pitch is also a method for calculating the pixel density (correlated with resolution) of an LED screen. For example, on a P1.0 16*9 inch LED video wall, there will be 4875*2710 pixels; if pitch pixel is P5.0 with the same screen size, the screen will have only 975*548 pixels.
As mentioned above, pixel pitch is important because it decides the optimal viewing distance of an LED display. Lower pixel pitch achieves finer details and smoother boards for the image being displayed. Hence you get a closer viewing distance. On the contrary, screens with higher pixel pitch need a relatively farther viewing distance.
So before you go to a direct view LED display, it’s quite necessary to fully consider your specific requirement, either a better image quality in a closer distance or in a farther distance with less demand for image quality.
Since pixel pitch really affects the result of using LED displays, it’s necessary to understand how to decide the right pixel pitch for your screen. In fact, there are some simple methods to do that.
Some people tends to multiply the pixel pitch number with 2 and 3, and gets a scope of optimal viewing distance in meters. For example, the optimal viewing distance of a P1.5 LED display should be between 1.5*2 to 1.5*3 meters, that is between 3 and 4.5 meters.
Others like to decide viewing distance by simply multiplying the pixel pitch number with 10, and get a value in feet. For example, a P1.5 LED screen has a 15 feet viewing distance, which is 4.75 meters.
Also, you can refer to below values as a guide for pixel pitch and viewing distance while choosing a LED display.
Pixel Pitch & Viewing Distance (for reference)
| Pixel Pitch | Viewing Distance |
| 1mm | 2 – 3m |
| 2mm | 4 – 6m |
| 5mm | 10 – 15m |
| 10mm | 20 – 30m |
| 40mm | 80 – 100m |
As we see from the above mentioned methods, the relationship between pixel pitch and viewing distance may slightly vary depending on different LED screen and personal preference, when deciding what pixel pitch to choose for your LED screen, it is best to experience the viewing distance of the screen by yourself before buying.
The dimension of individual pixels, or the LED dots on the screen, affects the pixel pitch of an LED screen the utmost. Smaller sized LEDs usually come out with smaller pixel pitch LED screens.
Kinglight offers a wide variety of LEDs in different dimensions for different pixel pitch LED screens.
Kinglight LEDs are usually named in accordance with their dimensions. The smaller their numbers are, the smaller dimensions they have. For example, the MC0404N-M1 LEDs can be made into P0.625 LED displays, while 2020 series LEDs are for 2.5mm, 2.6mm, 3.9mm and 4.8mm pixel pitch displays and 3535 series LEDs are for 8mm and 10mm pixel pitch LED displays.
In addition, the structure design of LED panels and specific requirement for resolution also affects the pixel pitch of an LED display.
