The pixel pitch describes the density of the pixels (LED die) on the LED display screen and is related to the resolution. Sometimes referred to as the dot pitch, it specifically refers to the distance from the center of a pixel to the center of an adjacent pixel (in millimeters unit). Since the pixel pitch reflects the space between two pixels, a smaller pixel pitch means less space between pixels. In other words, it means higher pixel density and higher screen resolution. rate.

The pixel pitch is very important because it affects the best viewing distance of the display. Lower pixel pitch values allow the image to achieve smoother edges and finer details. This allows the viewer to get closer to the screen and enjoy clear images without seeing individual pixels.

When determining the viewing distance and the pixel pitch, the thumb rule means that a smaller pixel pitch is equivalent to a smaller viewing distance. On the contrary, a larger pixel pitch also increases the minimum viewing distance. Therefore, a 1.2mm screen will have a higher resolution and a smaller optimal viewing distance than a 16mm screen.

Note that although higher pixel densities can improve visual quality, this does not mean that in any case, smaller pixel pitches are the ideal choice. The extra pixel density is designed to provide a closer viewing distance. At higher viewing distances, higher pixel densities lose their visual advantage and increase costs.

Smaller pixel pitches usually provide higher resolution but are more expensive. Because it requires more LED die to create a higher pixel density, materials and production costs are higher.

 Then the question is, what kind of pixel spacing is the most appropriate? The answer is that the consumer can determine the optimal pixel pitch value of the LED screen by determining the best viewing distance of the screen. The so-called best viewing distance refers to the critical point of image fidelity, if the observer is too close, the image quality will be reduced or the screen will appear pixelated.

 For example, a display with an interactive touch scheme requires a smaller pixel pitch to provide a clear image to a neighboring viewer. The LED screen that is played in front of the public, such as the LED screen suspended on the stage, can use a higher pixel pitch. In simple terms, a smaller pixel pitch can provide a higher quality image, but if the screen is far from the viewer, then the extra investment is not necessary.

Although these methods all have some guidance, there is actually no correct answer when determining the viewing distance. The viewing distance of the screen ultimately depends on whether the owner of the screen feels comfortable.
