Overview

What does Pixel Pitch mean with respect to an LED video display?

The scientific definition of pixel pitch with respect to an LED video screen is the distance, in millimeters, from the center of an LED bulb to the center of the next LED bulb, on a PCB board. The smaller or finer the pixel pitch, or the shorter the distance between the LED bulbs, the sharper are the images, and the closer a viewer can stand to the LED video display and see the images clearly. The larger the pixel pitch the longer is the distance between the LED bulbs. The larger the pixel pitch the farther away from the LED screen a viewer must stand so as not to see pixelation. The other critical significance of Pixel Pitch is that the pixel pitch indicates the distance in meters from an LED video display at which a viewer will not see individual pixels. For example, if the Pixel Pitch is P4 then at approximately 4 meters from the display a viewer will not see pixelation. At a Pixel Pitch of P1.25 the viewer will not see the LED bulbs at 1.25 meters. Fine pixel pitches for LED video displays now include P0.5, P0.7, P0.9, P1.25, P1.5. Military, medical applications and boardroom applications call for fine pixel pitches in order for the images to be extremely sharp. In choosing the appropriate pixel pitch for an LED video display the optimal viewing distance (OVD) for that particular application needs to be determined. The OVD is the shortest distance from the LED display at which pixelation is not apparent. Vanguard LED Displays offers a plethora of fine and very fine pixel pitch LED video displays (See below) that can satisfy the demands for fine and very fine pixel pitch LED video displays.
