Figure 3: 16x16Pixel Module (Front and Rear)
Driver/Pixel Board: The LED pixels are mounted directly onto the driver/pixel board. This board is
also responsible for the switching and intensity levels of the LEDs.
LED (light emitting diode): Low energy, high intensity lighting units.
Louver: Optional black plastic shade positioned horizontally above each pixel row. The louvers
increase the level of contrast on the sign face and direct LED light.
Module: 20mm Galaxy modules are 16 pixels high by 16 pixels wide (refer to Figure 3 above). Each
module is individually removable from the front of the sign.
Module Latch Assembly: Device utilizing a rotating retainer bar to hold the module firmly to the
sign frame. There are two per module: one near the top and one near the bottom.
Pixel: Cluster of LEDs. The number and color of the LEDs depends on sign application.
Power Supply: Converts AC line voltage from the load center to low DC voltage for one or more
module driver boards.
