What is pixel pitch?

Well that’s a good question and we are going to try to shed some light on the subject below.

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 millimeters from the center of a pixel to the center 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.

Even though that is pretty concise what does this actually mean for planning our your digital signage? Well it all has to do with Minimum Viewing Distance and Optimum Viewing Distance which is the range between the distance at which the human eye can perceive a LED pixel cluster as a single dot and the distance at which it can no longer perceive individual pixels.

So what does that mean in terms of helping you choose your display? Well both are tools to choose the right display but they differ one which one to focus on depending on the use case for the display you are going to be using.

So what does this all mean?

Well there are multiple different options on what the “rule of thumb” is for viewing distances… as outlined by these multiple companies.

Christie’s rule of thumb is 8 – which means you multiply the pitch by 8 to get the viewing distance in feet. 1mm pitch = 8 feet optimum viewing distance.

LG however gives the rule as 1mm per 3.5 feet for its direct view LEDs.

This is another good chart to start the conversation as well…
