Driver: Circuit board responsible for switching the intensity levels of the LEDs. The
driver mounts on the back of the module.
Fiber Optic: Technology that uses glass (or plastic) threads (fibers) to transmit data
from the computer to the display. A fiber optic cable consists of a bundle of glass
threads, each of which transmits messages modulated onto light waves.
Galaxy
®
: Daktronics trademarked name for LED monochrome or tri-colored matrix
signs.
LED (light emitting diode): Low energy, high intensity lighting units.
Network: Consists of multiple signs connected to each other.
Louver: Black shade positioned horizontally above each pixel row. The louvers
increase the level of contrast on the sign face and direct LED light.
Module: 64mm Galaxy
®
modules are 8 pixels high by 4 pixels wide. They consist of
a pixel board, louvers, and a driver.

Pixel: Cluster of LEDs. The number and color of the LEDs depends on the displays
application.
Pixel Board: The pixel board contains the LED clusters which mount into the metal
face panel. A module driver is attached to the back of each pixel board.
Power Supply: Converts AC line voltage from the load center to low DC voltage for
one or more module driver boards.
