P2.5 LED panels have a pixel pitch of 2.5mm
P1.8 LED panels have a pixel pitch of 1.8mm
(The pixel pitch (AKA pitch or dot pitch) is the density of the pixels)
The pixels on a P1.8 panel are spaced 1.8mm from the center of a pixel to the center of the adjacent pixel.
The pixels on a P2.5 panel are spaced 2.5mm from the center of a pixel to the center of the adjacent pixel.
A lower pixel pitch eg. P1.8 means less empty space between pixels which is the same as having a higher pixel density. This therefore improves the overall screen resolution however the cost also increases as the pixel pitch reduces.
It is important to consider the viewing distance of a DV-LED video wall, a smaller pixel pitch allows for a closer viewing distance. A P1.8 DV-LED Video Wall will have significantly higher resolution and a closer optimal viewing distance than a P1.8 DV-LED Video Wall.
The suggest viewing distances are as follows:
A P1.8 DV-LED Video wall when viewed from approximately 1.8m will appear as a seamless image where the individual LED Pixels are not distinguishable. A P2.5 DV-LED Video wall when viewed from approximately 2.5m will appear as a seamless image where the individual LED Pixels are not distinguishable.
