`ABSTRACT
`
`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.

`DISPLAY BOARD AND DISPLAY BOARD
`COMPONENTS
`
`[0001] The present disclosure relates generally to a display
`board and, more particularly, to the elements and construction
`of a modular display board. The present disclosure also
`includes methods of operating a display board as disclosed in
`patent applications filed in the United States Patent & Trade(cid:173)
`mark Office on Dec. 1, 2012 and entitled "Systems And
`Methods For Display Board Control", assigned U.S. Provi(cid:173)
`sional Patent Application No. 61/732,329, and "Systems And
`Methods For Powering A Display Board", assigned U.S. Pro(cid:173)
`visional Patent Application No. 61/732,330, both of which
`are incorporated herein by reference in their entirety.
`
`FIELD OF THE DISCLOSURE
`
`Background of the Disclosure
`
`[0002] There is a need for improvements of the type
`described herein for display boards for displaying still
`images, video, or both.
`
`SUMMARY OF THE DISCLOSURE
`
`[0003] The present disclosure provides a display board and
`display board components that overcomes deficiencies in
`prior lighting apparatuses. The display board can be capable
`of displaying still images and/or video. Use of the terms
`"video," "display," "image" or the like herein is not intended
`to limit the scope of the disclosure to a board, or components
`thereof, capable of displaying only still images, only video, or
`both still images and video. Thus, while various elements of
`the preferred embodiment may have the term "video" in their
`name, that term does not preclude use of that embodiment or
`element with still images.
`[0004] A display is disclosed 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; the
`louver comprising a panel defining a perimeter and one or
`more apertures, the one or more panel apertures associated
`with one or more of the plurality oflight emitting diodes; and
`the louver further comprising a flange extending from the
`panel perimeter to the frame perimeter and attaching the
`louver to the frame. The louver flange may comprising one or
`more barbs that facilitate a releasable snap-fit attachment of
`the louver to the frame. The frame may further comprise a
`flange defining the perimeter of the frame and the louver
`flange may further comprise one or more barbs that facilitate
`a releasable snap-fit attachment of the louver to the frame
`flange. The frame may further comprise a flange defining the
`perimeter of the frame and the louver flange may comprise
`one or more barbs that facilitate a releasable snap-fit attach(cid:173)
`ment of the louver to the frame flange when the barb resides
`in a recess on the frame perimeter flange. The louver panel
`may define a plane and the louver flange may extend perpen(cid:173)
`dicular to the plane. One or more bosses may extend from the
`louver panel to facilitate attachment to the frame. The one or
`more bosses may extend through an aperture defined in the
`circuit board to facilitate attachment to the frame. One or
`more barbs may also extend from the louver panel through an
`aperture defined in the circuit board to facilitate snap-fit
`attachment to the frame. The light emitting diodes may each
`comprising leg terminals mounted to the circuit board sur-
`
`rounded by a pool of potting. The louver may further com(cid:173)
`prise ribs extending from the louver panel to manage ambient
`light.
`[0005] Another display is disclosed comprising: a frame, a
`circuit board associated with the frame, a plurality of light
`emitting diodes comprising leg terminals electrically con(cid:173)
`nected to the circuit board, and a louver; the louver compris(cid:173)
`ing a panel defining one or more apertures, the a panel aper(cid:173)
`ture associated with a group of one or more of the plurality of
`light emitting diodes; and a potting pool covering the leg
`terminals of only those light emitting diodes in the group. A
`gasket can be between the louver and the circuit board, the
`gasket defining an aperture circumscribing the group of light
`emitting diodes. The aperture can define a perimeter of the
`potting pool. The gasket comprises a web and a rib extending
`from the web, the rib circumscribing the group oflight emit(cid:173)
`ting diodes. The rib may define a perimeter of the potting
`pool. The louver panel may further define a perimeter and the
`louver may comprise a flange extending from the panel
`perimeter and have one or more barbs that facilitate a snap-fit
