What is the Pitch(or "Dot Pitch" or "Pixel Pitch")?

The pitch of a LED display defines the distance between the pixels, expressed in millimeters. This fundamental measure determines the characteristics and the performances of a LED screens: the pitch indeed is a defining factor of a screen's viewing distance: #1 - The smaller is the pitch, the shorter is the minimum viewing distance, the higher is the total number of pixels present on the screen (and therefore higher is the screen's cost per area). #2 - The bigger the pitch is, the longer the minimum viewing distance will be, the lower  the total number of pixels present on the screen (and therefore the screen's cost per area will be lower) The pixel pitch therefore determines the LEDs density, which is usually called Resolution. It is important to notice that while reducing the pixel pitch, the LED density increase exponentially: for example, reducing the pitch by the 50% on the number of pixels grow of 4 times.
