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. ## Claims ### Claim 1 A display comprising: a plurality of modular display blocks, one or more of the modular display blocks comprising a frame defining a perimeter, a circuit board associated with the frame, a plurality of light emitting diodes associated with the circuit board, and a louver;
