Electronic Sign Terminology |
LED -
An acronym
that stands for Light Emitting Diode. Best described as
a miniature light bulb smaller than the size of a dime.
On average, these diodes have a life expectancy of
50,000 hours or 11.5 years of continuous use, thereby,
making them more economical than the standard
incandescent light bulb.
Candela -
A unit of
measurement of light intensity of light. An ordinary wax
candle generates one candela. A typical LED bulb's
brightness is measured in millicandela or mcd, while a
LED display's brightness is measured in NIT.
NIT -
A
measurement of luminance used primarily to indicate a
LED display's brightness. One NIT is equal to one
candela per square meter (1cd/m2).
Pixel -
A single dot
of light. A pixel can be composed of either a single LED
or a cluster of LEDs. Pixel size can vary. A large pixel
size will give you better fill with the electronic
message center.
Pitch - The distance
from the center of a pixel to the center of the next
pixel. Pitch influences the resolution of a LED display
that shows images. A small pitch translate to higher
resolution. A large pitch translates to larger
text/character sizes.
RGB - Red, Green,
and Blue. These three colors combined can produce the
full spectrum of color.
Full Matrix
-
A full
matrix display allows the user to combine the entire
display’s pixels to produce larger characters and
graphics.
NTSC - (National TV
Standard Committee). A color TV standard that was
developed in the U.S. Administered by the FCC, NTSC
broadcasts 30 interlaced frames per second, which is 60
half frames per second. The NTSC signal is a composite
of red, green and blue.
RF - An acronym
for Radio Frequency. RF is frequently used for wireless
communication.
