Pixel Pitch Defined | What is Pixel Pitch?
Dot pitch, pitch, pixel pitch, these three professional terms have the same meaning, referring to the distance from the center of one lamp bead to the center of the adjacent lamp bead in the LED display, The unit is mm.
In the industry, the letter “P” in the word “pixel pitch” is also commonly used to refer to the dot pitch for short. For example, a screen with a dot pitch of 1.5mm is called P1.5, and a screen with a dot pitch of 2mm is called P2.
With the advancement of SMD and COB lamp bead packaging technology, the current point spacing can be smaller than 1mm and larger than 10mm. IDISPLAY has profound research and development capabilities and accumulated rich engineering experience. The screen pixel pitch covers 0-1mm, 1-10mm, 10+mm, and is in a leading position in the industry.
LED display with LED dot spacing less than P2.5 is called small pitch LED display, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25, P1.0 and other LED display products
The importance of pixel pitch
The smaller the dot pitch, the greater the pixel density, the greater the resolution, the closer the viewing distance, the more delicate the displayed image, and the better the final visual effect for people. Of course, the cost is relatively high.
Relatively, the larger the dot pitch, the smaller the pixel density, the smaller the resolution, the farther the viewing distance, and the less delicate the displayed image. Finally, for the larger dot pitch, better and more delicate visual effects can be obtained. The viewing distance must be extended. Of course, the cost is also relatively low.
How to choose the pixel pitch
It can be seen from the above discussion that the size of the dot spacing and the viewing distance directly affect people’s visual effects.
Indoors, the space viewing distance itself is limited, in order to better and more delicate visual effects, generally choose a smaller point spacing. Outdoors, there is no limit to the viewing distance in space, and a smaller dot pitch can also be selected, but for lower cost and higher cost performance, a larger dot pitch is generally selected.
In the end, you will probably ask, knowing the viewing distance, how do I know how much dot spacing is appropriate? In fact, there is no absolutely unified standard formula in the industry for the conversion of viewing distance and point spacing. And everyone’s subjective visual experience is different. The following editor gives the conversion formula calculated by IDISPLAY LED display for reference: (distance unit: meters)
LED Pixel Pitch Calculator
Minimum viewing distance (m) (the distance that can display a smooth image) = pixel pitch (mm)
The most suitable viewing distance (m) (the distance that can display a highly clear picture) = pixel pitch (mm) × 3
The farthest viewing distance = screen height (m) × 30
