LED display screens are widely used in daily life, from small red screens in storefronts to large full-color LED advertising screens .
However, many people may not understand the professional technology of LED displays.
LEGIDATECH editor will tell you what’s the meaning of “Pixel pitch” in a simple and understandable way.
1. What is the LED Screen pixel pitch ?
P3.91mm actual product picture
Dot pitch, pitch, and pixel pitch, these three professional terms have the same meaning, referring to the distance between the center of a LED bead to the center of an adjacent LED bead in an LED display screen, measured in millimeters.
In the LED Screen industry, the letter “P” in the word “pixel pitch” is also commonly used to refer to dot pitch.
For example, a screen with a 1.5mm dot pitch is called P1.5, and a screen with a 2mm dot pitch is called P2. The spacing between other points, and so on.
In addition, the spacing between points is often referred to together with the product series name
With the advancement of SMD and COB bead packaging technology, the current point spacing can be as small as 1mm or smaller , and as large as 31mm.
After 13 years of development, LEGIDATECH has profound research and development capabilities and accumulated rich engineering experience.
The product point spacing covers 0.1-1mm, 1-10mm, and 10+mm, and is in a leading position in the industry.

The importance of pixel pitch
The smaller the distance between the points, the higher the pixel density ,which results in higher resolution and shorter viewing distance.
The displayed image becomes more delicate, and the final visual effect is better. Of course, the cost is relatively high.
On the contrary, the larger the point spacing, the smaller the pixel density, which results in lower resolution and longer viewing distance.
The displayed image is not as delicate, and in order to achieve better and more delicate visual effects with larger point spacing, the viewing distance must be extended. Of course, the cost is also relatively low.
How to choose suitable pixel pitch screen ?
| Pixel pitch | Minimum viewing distance | Optimum viewing distance |
| 1mm | 1m | 3m |
| 2mm | 2m | 6m |
| 3mm | 3m | 9m |
| 4mm | 4m | 12m |
| 5mm | 5m | 15m |
| 6mm | 6m | 18m |
| 7mm | 7m | 21m |
| 8mm | 8m | 24m |
| 9mm | 9m | 27m |
| 10mm | 10m | 30m |
Conversion of viewing distance and point spacing
From the above discussion, it can be seen that the size of point spacing and viewing distance directly affect people’s visual effects.
In indoor environments, the viewing distance of the space itself is limited, and for better and more delicate visual effects, smaller pixel pitch is generally chosen.
In outdoor installations, there is limit to the viewing distance of the space, and smaller pixel pitch can also be chosen.
However, for lower costs ,then larger point spacing is generally chosen.

In the end, you may ask, how do I know what the appropriate Pixel Pitch is when I know the viewing distance?
In fact, there is no absolutely unified standard formula in the industry for the conversion of viewing distance and Pixel pitch.
And everyone’s subjective visual perception is also different. The following is the conversion formula calculated by the LEGIDATECH LED display screen, which can be used as a reference: (Distance unit: meters)
Minimum viewing distance (able to display smooth images)=Pixel pitch (mm) × 1000/1000
The most suitable viewing distance (distance that can display highly clear images)=Pixel pitch (mm) × 3000/1000
Farthest viewing distance=screen height (meters) × 30

FAQ
- What is the main pixel pitch LED screen installed in churches?
RE: It is Indoor p3.91, Pixel pitch 3.91mm.
With the development of technology and the reduction of production costs, the price of high-definition displays has become very affordable. More and more people will choose P2 displays. Our newly developed Ehonor series displays are affordable and of high quality, achieving a more perfect viewing experience
- What is the main pixel pitch LED screen installed for outdoor billboard ?
RE: At present, the most commonly used outdoor large screen with an area of over 30 square meters is the P10mm LED display screen. The viewing distance of outdoor large screens is relatively long, so choosing P10mm is the most cost-effective option. For large screens with an area of less than 30 square meters, we can choose P5mm, P6mm, and P8mm
- What is the main pixel pitch LED screen installed for cinema?
RE: Cinemas require clearer picture quality effects, currently mainly using P2-P3mm
- What is the main pixel pitch LED screen installed for movable events?
RE: The most commonly used rental display screens at present are indoor P3.91mm and outdoor P4.81mm. With the advancement of technology and the reduction of production costs, indoor rental display screens are selected as P2.6mm, P2.9mm, and outdoor display screens are selected as P3.91mm
