Abstract

The present invention concerns a display assembly comprising an organic light-emitting diode display device comprising at least one OLED comprising an emitting stack placed on a transparent substrate, whose back face is placed on the emitting surface of the OLED, and a secondary object to be illuminated, said transparent substrate comprising a front face and at least one side face arranged to light a secondary object.

First claim

What is claimed is:

1. A display assembly comprising:
an organic light-emitting diode display device including at least one OLED having an emitting stack placed on a transparent, semi-transparent or translucent substrate, a back face of the substrate being placed on the emitting surface of the OLED; and
a secondary object to be illuminated,
wherein said substrate includes a front face on an opposite side of the substrate from the back face, and at least one side face through which light emitted by the OLED is extracted to light a secondary object,
wherein the side face of the substrate extends an entirety of a distance from the front face of the substrate to the back face of the substrate, and
wherein the OLED includes a side surface, the side surface of the OLED is arranged immediately adjacent the side face of the substrate.

2. An assembly according to claim 1 , further comprising an analogue time display.

3. The assembly according to claim 2 , wherein the secondary object includes the analogue time dial.

4. The assembly according to claim 1 , wherein the secondary object is arranged inside a watch aperture, the watch aperture being formed by the side surface of each of the OLED and the side face of the substrate.

5. The assembly according to claim 1 , wherein said side face is depolished to produce diffused light during use.

6. A positive assembly according to claim 1 , wherein said side face is at an angle of between 90 and 135° relative to the front face.

7. An assembly according to claim 1 , wherein said transparent substrate has a refractive index of at least 1.5.

8. The assembly according to claim 1 , wherein opaque covers are arranged on the side faces that do not illuminate the secondary object.

9. The assembly according to claim 1 , wherein the front face of the substrate includes an integrated or added decoration.

10. The assembly according to claim 1 , wherein the substrate is suiniounted by a semi-transparent dial.

11. An assembly according to claim 1 , wherein said transparent substrate has a refractive index between 1.6 and 1.8.

12. A watch comprising:
a display assembly including an organic light-emitting diode display device having at least one OLED including an emitting stack placed on a transparent, semi-transparent or translucent substrate, a back face of the substrate being placed on the emitting surface of the OLED; and
a secondary object to be illuminated,
wherein said substrate includes a front face on an opposite side of the substrate from the back face, and at least one side face through which light emitted by the OLED is extracted to light a secondary object,
wherein the side face of the substrate extends an entirety of a distance from the front face of the substrate to the back face of the substrate, and
wherein the OLED includes a side surface, the side surface of the OLED is arranged immediately adjacent the side face of the substrate.
