4. The display device ( 1 ) according to claim 1 , wherein the processing unit ( 10 ) is connected to:
the devices ( 6 a , 6 b ) for identifying the viewer and the decorative object ( 2 ), and
a database ( 13 ) comprising viewing profile data for the viewer, viewing profile data relating to a behavioural state of the viewer, data on the features of the decorative objects and viewer and/or object identification data.
5. The display device ( 1 ) according to claim 1 , wherein the main illumination device ( 8 a ) comprises a first illumination module ( 9 a ), a second illumination module ( 9 b ) and/or a third illumination module ( 9 c ), each provided with:
a plurality of light-emitting elements, or
a single light-emitting element that is coupled to a modulator.
6. The display device ( 1 ) according to claim 1 , wherein the main illumination device comprises:
a first illumination module ( 9 a ) is arranged above the area of interest ( 3 ) and thus above a plate of the support element ( 5 );
a second illumination module ( 9 b ) is disposed below the area of interest ( 3 ) and thus below the plate of the support element ( 5 ); and
a third illumination module ( 9 c ) is arranged in a periphery of the area of interest ( 3 ) and thus of the plate of the support element ( 5 ).
7. The display device ( 1 ) according to claim 1 , wherein the secondary illumination device ( 8 b ) is arranged above the case ( 4 ).
8. The display device ( 1 ) according to claim 1 , wherein the decorative object ( 2 ) is a piece of jewelry or a timepiece.
9. A display device ( 1 ) for displaying a decorative object ( 2 ), comprising a case ( 4 ) provided with a support element ( 5 ) on which an area of interest ( 3 ) is defined, inside which said decorative object ( 2 ) is likely to be disposed and/or handled, the display device ( 1 ) including:
devices ( 6 a , 6 b ) for identifying a viewer and the decorative object ( 2 );
a system ( 7 ) for illuminating the area of interest ( 3 ) comprising a main illumination device ( 8 a ) and a secondary illumination device ( 8 b ) provided with light-emitting elements which are configured to illuminate the area of interest ( 3 ) as a function of a viewing profile data of the viewer, and/or as a function of a behavioural state of the viewer, and/or as a function of the features of the object ( 3 );
a processing unit ( 10 ) configured for:
generating a command for controlling the illumination properties of the main illumination device ( 8 a ) and/or of the secondary illumination device ( 8 b ) as a function of criteria concerning a visual perception by the viewer of the object ( 3 ); and
controlling the main illumination device ( 8 a ) and/or the secondary illumination device ( 8 b ) as a function of said command for controlling the properties of these illumination devices ( 8 a , 8 b ),
wherein the main illumination device ( 8 a ) further comprises an adjustment element ( 14 ) entirely or partly arranged around the area of interest ( 3 ) and extending vertically between a base ( 12 a ) and a ceiling ( 12 b ) of the case ( 4 ).
10. The display device ( 1 ) according to claim 9 , wherein the adjustment element ( 14 ), which is controlled by the processing unit ( 10 ), can switch between the following states:
a state of reflectance of light radiation originating from the first, second or third illumination module ( 9 a , 9 b , 9 c ) towards the area of interest ( 3 ), and
a state of scattering of light radiation originating from the secondary illumination device ( 8 b ) towards the area of interest ( 3 ).
11. A display device ( 1 ) for displaying a decorative object ( 2 ), comprising a case ( 4 ) provided with a support element ( 5 ) on which an area of interest ( 3 ) is defined, inside which said decorative object ( 2 ) is likely to be disposed and/or handled, the display device ( 1 ) including:
