When we talk about LED screens, it is inevitable for us to come across an essential concept “pixel pitch”. Pixel pitch does matter to an LED screen, but how? And how to choose the appropriate pixel pitch for an LED screen? This article will give you some guidelines to make it out.
What is Pixel Pitch ？
Pixel pitch describes the density of the pixels (LED clusters) on an LED display and correlates with resolution. Sometimes referred to as pitch or dot pitch, the pixel pitch is the distance in millimetres from the centre of a pixel to the centre of the adjacent pixel. Since pixel pitch indicates the amount of space between two pixels, a smaller pixel pitch means there is less empty space between pixels. This equates to higher pixel density and improved screen resolution.
Why is pixel pitch important?
Pixel pitch is important because it influences the optimal viewing distance for your display. An image achieves smoother borders and finer detail with lower pixel pitch values. This allows the viewer to stand closer to the screen and enjoy a clear image without the distraction of discerning individual pixels. When determining viewing distance and pixel pitch, the rule of thumb is that a smaller pixel pitch allows for a closer viewing distance. Conversely, a higher pixel pitch elongates the minimum viewing distance. So, a 1.2mm screen will have significantly higher resolution and a closer optimal viewing distance than a 16mm .
While higher pixel density delivers improved visual quality, it is not the ideal option for every situation. Additional pixel density is intended for a closer viewing distance. At a greater viewing distance, higher pixel density loses its visual advantages and simply increases the cost of the display.
What is the relationship between dot pitch and led display?
When shopping for a display, you'll frequently hear resolution figures, such as "1080p" or "4k" displays. The pixel pitch of your LED wall is a clear indicator of its resolution potential: The higher the possible resolution, the lower the pixel pitch. Using the normal rules of thumb for pixel pitch plus distance, 1080p resolution is available for most LED wall applications. A pixel pitch that is lower pixel could be necessary if you want higher resolution. However, the image quality and material you're displaying on the LED wall is a crucial factor to consider. For instance, regardless of the pixel density, a low-quality photograph will yield low-resolution results.
While the resolution is important, it does not always imply that it is superior! Higher pixel density is associated with a lower pixel pitch. Because there is more LED on a single panel with a higher pixel density, the LED screen will likely be more expensive and require more care. The viewing distance and visual performance of an LED screen are also affected by the pixel pitch.
How to calculate the total number of pixels of a LED screen?
The procedure is very simple: for example, if we want a 3 x 1 m screen, we will convert the size to square meters, multiplying the base by the height. In this case, we would have a 3m2 LED screen. Next, we would have to look for a pixel pitch that, multiplying the number of pixels per m2, would give us an equal value or above the 30,000 pixels mentioned above.
For example, we multiply the surface by 10 mm pixel (equivalent to 10,000 pixels / m2, according to this table to calculate the pixel pitch of a LED screen). Therefore, 3 m2 x 10,000 pixels / m2 = 30,000, so we would reach the minimum number of pixels recommended for the reproduction of images and videos.
