Abstract: A module for a digital display panel includes a circuit board, a first face of which presents a network of light emitting diodes. The module also includes a chassis fixed on a second face of the circuit board, and a water permeable connector mounted on the circuit board. The chassis includes a base around the water permeable connector, a top part of the base having at least one groove, wherein a seal is inserted. Further, the module includes a power supply unit fitted with a continuous voltage connector surrounded by a ferrite and fitted in the water permeable connector. The power supply unit is attached to the chassis so that a lower plate of the power supply unit co-operates with the seal of the base to ensure a seal around the water permeable connector and the DC voltage connector of the power supply unit.

Abstract: A communicating board includes: a display medium including a sheet of fabric, the sheet of fabric comprising, on at least one surface, loops intended to cooperate with a gripping strip provided with hooks; at least one first gripping strip provided with hooks enabling to hold in position the display medium, and at least one substantially rectilinear profile including a first planar connecting surface having the at least one first gripping strip provided with hooks positioned thereon. The first planar connecting surface is inclined towards a rear surface of the display medium when the latter cooperates with the at least one first gripping strip provided with hooks, the first planar connecting surface forming with a visible planar surface of the display medium an angle greater than 30°.

Abstract: A textile complex adapted to be attached to a communicating panel includes a textile sheet having, on at least one face, loops adapted to engage with a self-gripping strip provided with hooks; a coating film attached to a face of the textile sheet; and a printing ink deposited on the coating film. The textile complex has a capacity for preferential elastic deformation in a direction of deployment on the communicating panel. A communicating panel and to a corresponding method of display are also provided.

Abstract: Communication display comprises a light source for backlighting an advertising spot or similar, arranged on a support. The light source comprises a web of optical fibres arranged facing the back of the support and adapted for emitting light laterally. Optical fibres present on at last one edge of the web are assembled in a plurality of bundles, each bundle being equipped at its free end with an assembling ring for securing each of the fibres with regard to others of the same bundle. The light source also includes a plurality of point sources facing at least one edge of the web of optical fibres, and convergent optical systems arranged facing each point source for uniformly collimating light rays emitted by the point sources towards the optical fibres. The convergent optical systems are arranged in a ball joint connection with centering supports and members for aligning the assembling rings.

Abstract: A display device with horizontal or vertical, alternating or continuous scrolling of at least two juxtaposed posters forming a strip, comprises a substantially rectangular parallelepiped outer geometry with the posters being viewed on a rectangular front frame. The strip is driven in a translational movement parallel to the front frame by at least one power roller. The device further comprises two independent modules, each adapted for rotationally guiding at least one power roller or at least one idle roller. The modules are assembled together by at least one beam and are located on the shorter sides of the rectangle formed by the front frame.

Abstract: A device for tensioning and maintaining a canvas, comprising a frame having a groove, and at least one deformable batten. The canvas is stretched and maintained on the frame by wedging it between the groove and the deformable batten. The deformable batten comprises a substantially V-shaped section which is oriented towards the bottom of the groove, a sharp edge which is used as a pivot to enable the deformation thereof, and two flanks which are used to wedge the canvas in the groove. The invention is characterized in that the batten is locked in a narrow section of the groove by two enlargements extending on one flank of the batten in the same direction as the batten.

Abstract: The invention relates to a display medium (1) intended to be installed in a scrollable device, the edges of which can be guided laterally inside the scrollable device. The inventive medium includes several adjacent sections (2, 3, 4) which are reversibly interconnected by means of the opposing horizontal edges thereof (10 13) including a lateral rod (7, 17, 27, 8, 18,38) located on each of the lateral edges extending continuously over each of the adjacent sections.
