Abstract
A luminous panel includes at least two juxtaposed OLED devices that form a front face of the luminous panel and define two light-emitting zones separated by an intermediate zone, and a luminous joint forming mechanism that ensures, when the two OLED devices are in an on state, visual continuity between the intermediate zone and the two emitting zones, the luminous joint forming mechanism being located at a back of or flush with the front face of the panel.
Claims20
A luminous panel comprising:
- at least two juxtaposed OLED devices that form a front face of the luminous panel and define two light-emitting zones separated by an intermediate zone;
- and
- luminous joint forming means that ensure, when the two OLED devices are in an on state, visual continuity between the intermediate zone and the two emitting zones, the luminous joint forming means being located at a back of or flush with the front face of the luminous panel
- wherein the luminous joint forming means comprises a redirecting prism placed at the back of the intermediate zone between two adjacent edges of the two juxtaposed OLED devices, a first reflective surface of the prism facing the edge of one of the two OLED devices whereas a second reflective surface of the prism faces the edge of the other OLED device to redirect light emitted by at least one of the two OLED devices toward a front of the intermediate zone.

A luminous panel, comprising:
- at least two juxtaposed OLED devices that form a front face of the luminous panel and define two light-emitting zones separated by an intermediate zone, the two OLED devices being supported on at least one support;
- and
- luminous joint forming means that ensure, when the two OLED devices are in an on state, visual continuity between the intermediate zone and the two emitting zones, the luminous joint forming means being located at a back of or flush with the front face of the luminous panel,
- wherein the luminous joint forming means includes a machined portion of a support of the at least one support that supports at least one of the two OLED devices, the machined portion creates a thinned portion of the support behind the two OLED devices, the machined portion of the support forming a reflective surface positioned, at a back of the intermediate zone, facing one edge of at least one of the OLED devices, to redirect light emitted by the OLED device toward a front of the intermediate zone.

- and
- luminous joint forming means that ensure, when the two OLED devices are in an on state, visual continuity between the intermediate zone and the two emitting zones, the luminous joint forming means being located at a back of or flush with the front face of the luminous panel,
- wherein the luminous joint forming means comprises scattering means for scattering light emitted by a light source toward a front of the intermediate zone, and
- wherein the light source is an external light source coupled to an edge face of a scattering plate, the scattering plate being placed in or at a back of the intermediate zone, a main face of the scattering plate oriented toward a front of the intermediate zone being configured to extract at least some of the light emitted by the external light source.
