Driver: Circuit board responsible for switching the intensity levels of the LEDs. The
driver is located inside the driver box and mounts on the back of the module.
Fiber Optic: Technology that uses glass (or plastic) threads (fibers) to transmit data
from the controller to the display. A fiber optic cable consists of a bundle of glass
threads, each of which transmits messages modulated onto light waves.

matrix signs.
Latch Access Fastener: Device utilizing a rotating retainer bar to hold the module
firmly to the display frame. There is one latch near the center of the module on the
right side.
LED (light emitting diode): Low energy, high intensity lighting units.
Louver: Black shade positioned horizontally above each pixel row. The louvers
increase the level of contrast on the display face and direct LED light.
Module: 89mm Galaxy

modules are 8 pixels high by 8 pixels wide. They consist of
pixel strips, louvers, and a driver. Refer to
for identification of parts.
Network: Consists of multiple signs connected to each other.
