The closer
the pixels are to each other, the higher the resolution
or density of the character or graphic image. Higher
detailed images can be shown with higher resolution
displays. Simply stated, the more pixels used in an
electronic LED sign, the higher the resolution of that
display and the image will be. The smaller the pixels,
the more that can fit into the display area.
-
Standard
resolution displays are designed for average viewing
(450 to 1,000 feet).
-
High
resolution displays are designed for closer viewing
distances (100 to 450 feet) and support graphics in
greater detail.
-
A pixel
can be one or more LED?s.
-
A
discrete LED is one individual diode.
-
LED
clusters are multiple LED?s installed as a single
pixel unit.
 Pixel
Pitch
The distance
from the center of one pixel to the center of the next
adjacent pixel is called pixel pitch. The letters and
numbers on LED signs are composed of individual or
clusters of LEDs that have spaces between them. This
spacing is called pitch. If the number of LEDs on a sign
remains the same, then the greater the pitch, the
further away a viewer must be in order to read the
sign?s text. (LED brightness is also a factor because
light helps to bridge the gap between LEDs.)
-
The
distance from the center of one pixel to the center
of the next adjacent pixel is called center to
center spacing or pixel pitch.
The
closer the pixels are to each other, the higher the
resolution or density of the character or graphic
image.
-
Low
resolution characters are designed for distance
viewing
-
High
resolution pixel pitch is designed for close-up
viewing
The number of
LEDs per pixel is determined by the display resolution.
Greater center-to-center spacing increases the number of
LEDs per pixel.
The reason for this increase in LEDs per pixel is to
maintain a superior outdoor NIT rating (brightness).
