Light-emitting module integrating a flexible organic light-emitting diode

A luminous module of a luminous and/or signalling device of an automotive vehicle, comprising:

• a. a flexible organic light-emitting diode mounted on a transparent substrate, the transparent substrate includes an interconnection layer with a network of electrical tracks for supplying electrical power to the organic light-emitting diode;
• b. a support of the flexible organic light-emitting diode, the support being designed to shape at least part of the flexible organic light-emitting diode and the transparent substrate in a predetermined shape;
• the at least part of the organic light-emitting diode being fastened to the support by means of an adhesive;
• c. a flexible printed circuit board;
• wherein the transparent substrate includes a portion protruding beyond the organic light-emitting diode and facing a portion of the support, in that the flexible printed circuit board is electrically connected to the interconnection layer at this portion of the transparent substrate and in that the flexible printed circuit board is fastened to this portion of the support by means of an adhesive, wherein the adhesive fastening the flexible printed circuit board to the support is identical to the adhesive fastening the organic light-emitting diode to the support, and wherein the adhesive is a double-sided adhesive layer, and wherein the support has a first thickness in a region supporting the organic light-emitting diode and a second thickness, different from the first thickness, in the portion of the support facing the protruding portion of the transparent substrate, the second thickness accommodating a difference in thickness between the organic light-emitting diode and the flexible printed circuit board such that mechanical stress on the transparent substrate is avoided.
