Driver Board: This driver board is also responsible for
the switching and intensity levels of the LEDs. Refer to
Galaxy
®
: Daktronics trademarked name for LED
monochrome, tri-colored, or RGB matrix displays.
LED (light emitting diode): This is a low energy, high
intensity lighting unit.
Louver: Black metal shade positioned horizontally
above each pixel row. The louvers increase the level of
contrast on the display face and direct LED light.
Module: The modules for the 133mm/171mm Galaxy
®
displays are 4 pixels wide
by 7 pixels high. Because of their large size they are more appropriately called
“module doors”. The module doors have hinges on the left edge, and can be opened
up, much like a door, to access internal components.
Pixel: A pixel is a single LED or cluster of LEDs. The number and color of the
LEDs depends on display application.
Power Supply: Converts AC line voltage from the load center to low DC voltage for
multiple module driver boards
