Description

Title of the invention: Multimedia module with remote electronics in DisplayPort

[0001] The invention relates to the field of multimedia sets and more particularly to multimedia sets comprising a remote electronic module.

[0002] A multimedia system is defined as an assembly comprising a display panel or a screen of the television or monitor type, including a display module and an electronic module that controls said display panel in cooperation with the display module. The display module may be of the following technology: liquid crystal display (LCD), liquid crystal display (LCD), liquid crystal display (LCD), or organic light-emitting diode (OLED).

[0003] The electronic module includes the electronic control boards for the multimedia system. These electronic boards are the most prone to failure and, thanks to the remote location of the electronic module, can be quickly replaced or repaired without intervention at the display panel or display module level.

[0004] The electronic module is connected to the display module by two high-definition multimedia interface cables of the DisplayPort type for the display and a 12-strand cable for all power supplies of any category in order to avoid interference in the displayport cables.

[0005] The invention relates to a multimedia assembly comprising an electronic module comprising at least one electronic board on which a plurality of connectors are positioned, each connector of the plurality being configured to cooperate with a display port interface cable.

[0006] Thanks to the use of DisplayPort multimedia interface cables, there are no low-voltage differential transmission electrical signals disrupted by low-power supply. Furthermore, since high-definition DisplayPort multimedia interface cables are standardized, it is easier to obtain them and upgrade the multimedia system.

[0007] According to one feature of the invention, the multimedia system further comprises a display module connected to an electronic module by two high-definition multimedia interface cables (DisplayPort), said electronic module being located remotely from the display module. Thus, the remote distance between the display module and the electronic module can reach 15 meters, depending on the model.

[0008] According to one feature of the invention, the display module comprises at least one electronic board on which a plurality of connectors are positioned, each connector of the plurality being configured to cooperate with high-definition multimedia display port interface cables.

[0009] According to a feature of the invention, at least one of the connectors of the electronic module is connected in series with a connector of the display module and another connector of the electronic module.

[0010] According to one feature of the invention, the electronic module is equipped with a cable reversal detection system configured to send a continuous signal through the cables and, when the signal is interrupted, to signal a cable reversal. The reversal signal allows the installer to immediately correct the cable connection.

[0011] Advantageously, the electronic module includes at least one indicator light that illuminates in the event of a cable reversal, the indicator light being connected to the cable reversal detection system. The indicator light alerts the installer to a reversal.

[0012] According to one feature of the invention, the detection system is designed to shut down the display module if a cable reversal is detected. Shutting down the display module prevents damage to the display panel associated with the display module.

[0013] According to one feature of the invention, the cable reversal detection system is configured to operate for a standard definition display module and / or for a high definition or ultra high definition display module, the switch between one or the other of the display modules is carried out by at least one switch integrated into the electronic module.

[0014] The invention will be better understood from the following description, which relates to one or more embodiments of the present invention, given by way of non-limiting examples and explained with reference to the accompanying schematic drawings, in which: The multimedia assembly 1 according to the invention comprises an electronic module 2, a display module 3, and a display panel 4. The electronic module 2 is offset from the display module 3 and from the display panel 4 as illustrated in [Fig. 1]. Furthermore, the electronic module 2 is connected to the display module 3 by two DisplayPort cables 5 as illustrated in [Fig. 1] and a 12-strand cable 6.

[0015] As shown in [Fig. 1], the electronic module 2 comprises an electronic board on which three connectors 7a, 7b, and 8 are mounted, configured to cooperate with cables 5 and 6. Furthermore, the display module 3 comprises an electronic board on which three connectors 7'a, 7'b, and 8' are mounted, configured to cooperate with cables 5 and 6.

[0016] Of course, the invention is not limited to the embodiments described and shown in the accompanying figures. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
