  • Patent number: 11678455
    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.

  • Publication number: 20220104381
    Abstract: A module for a digital display panel includes an electronic board, a first face of which has an array of light-emitting diodes arranged in rows and columns with a substantially constant pitch. The module further includes a frame fastened onto a second face of the electronic board opposite the first face and at least one water-permeable connector for an optical fiber, mounted on the frame. The frame includes a baseplate integrating the at least one water-permeable connector. The module includes a cover attached to the baseplate so as to form a watertight volume inside the baseplate. The cover includes at least one opening provided with sealing means intended to ensure sealing around at least one optical fiber connected to the at least one water-permeable connector.
