Attorney Docket: 074280-0526 (LSIL-0055) A display board is disclosed for displaying video or still images using light emitting diodes as pixels. The connections of one or more of the light emitting diodes to a carrying circuit board, for example by terminal legs, such that the connections of each light emitting diode are encased in separate pools of potting. Alternatively, each pool of potting could encase the connections of multiple light emitting diodes. The circuit board is associated with a frame and a louver. The louver has a panel and a flange about its perimeter and the flange extends to attach to the frame with a snap-fit attachment. The louver also provides one or more barbs extend from the louver panel through an aperture defined in the circuit board and snap-fits to the frame. The display board also provides a power supply having a power supply case that defines a mounting slot having an insert aperture with a width sized to allow a distal end of a mounting tab extending from the frame to pass through the power supply case. The power supply case further defines a retention slot having a width sized to prevent the frame mounting tab distal end from passing through the base plate. DMUS 39376125-2.074280.0526 - 41 - |
