Such known cover elements comprise an aesthetic layer made of a genuine material such as wood, leather or metal.
This aesthetic layer is configured to hide the display element when it does not generate any image. However, such cover elements made of such aesthetic layers are generally very expensive due to the use of the aesthetic layer made of the genuine material.
One aim of the invention is to overcome the above-mentioned drawbacks by proposing a cover element being less expensive and presenting a favorable aspect.

In particular, for example, the display area presents the visual appearance of the predefined material when the display zone extends in front of a display element which is switch off.
Thanks to said portion of the external face of the support, the display area presents the texture of the predefined material. Thus, by touching the display area a person can feel the texture of the predefined material.
Thus, the combination of the portion of the decorative layer and the portion of the support enables to reproduce the visual appearance and the feeling of touching of a predefined material, being for example a genuine material such as leather, wood, metal, etc.
Additionally, it is possible to choose inexpensive materials as compared to genuine materials to realize the cover element and in particular to imitate the visual appearance and the texture of the predefined material, i.e. to obtain a favorable aspect of the cover element.

Additionally, since the layers of the cover element 14 are translucent in the display area 18, good optical properties for the cover element 14 are obtained so that when an image 20 is generated by the display element 12 in the illumination configuration, the generated image 20 displayed in the display area 18 has an optimal quality. Thus, an image 20 generated by the display element 12 can be seen in an optimal way in the display area 18 of the cover element 14 by passengers of the vehicle.
A method for producing the display assembly 10 is described in the following.
The method for producing the display assembly 10 comprising manufacturing the cover element 14 and assembling the cover element 14 to the display element 12.

For example, during the sub-step of etching, the external face 40A of the substrate layer 40 is etched so that it has the roughness of the surface of the predefined material 22.
For example, during the sub-step of coating, the external face 40A of the substrate layer 40 is coated with the first, second, third and fourth coating layers 41, 42, 43, 44.
The coating layers 41, 42, 43, 44 are applied coating by coating using, for example, metalorganic chemical vapour deposition (also known by “MOCVD”).
According to a particular example of the method of manufacturing the cover element 14, the step of realizing the support 30 depends on the values of the pixels of an acquired image of the predefined material 22 or on the values of the pixels of a filtered acquired image of the predefined material 22.
In particular, for example, the step of realizing the texture imitation portion 30P of the support 30 depends on the values of the pixels of said acquired image of the predefined material 22 or on the values of the pixels of said filtered acquired image of the predefined material 22.
In this case, the sub-step of etching and/or the sub-step of coating of the step of realizing the support 30 depends on the values of the pixels of said acquired image of the predefined material 22 or on the values of the pixels of the filtered acquired image image of the predefined material 22.

The step of realizing the visual appearance imitation portion 32P comprises a sub-step of providing the base layer 46 and a sub-step of coating the base layer 46 with the decorative coating 36 for forming the visual appearance imitation portion 32P.
For example, the sub-step of coating comprises printing the base layer 46 with the decorative coating 36 for forming the visual appearance imitation portion 32P.
According to a particular example of the method for manufacturing the cover element 14, the step of realizing the visual appearance imitation portion 32P of the decorative layer 32 depends on the values of the pixels of said acquired image of the predefined material 22 or on the pixels of said filtered acquired image of the predefined material 22. Thus, in this example, the decorative pattern 35 of said visual appearance imitation portion 32P of the decorative layer 32 reproduces said acquired image or said filtered acquired image of the predefined material 22.
In particular, in this example, the sub-step of coating the decorative coating 36 depends on the values of the pixels of said acquired image of the predefined material 22 or on the values of the pixels of said filtered acquired image. In particular, the intensity of the decorative coating 36 depends on said pixels.
For example, the provided decorative layer 32 and the obtained support 30 are assembled by lamination.
In particular, the decorative layer 32 is laminated on the internal face 30B of the support 30.
Then, the manufactured cover element 14 is assembled to the display element 12 using the optical bonding layer 16.

The external face 102A of the appearance layer 102 and the texture imitation portion 30P form the external surface 100A of the trim element 100.
The external face 102A of the appearance layer 102 has at least the same visual appearance as the visual appearance imitation portion 32P.
Advantageously, the external face 102A of the appearance layer 102 has the same texture as the texture imitation portion 30P.

The method for manufacturing the display assembly of this embodiment is described only by differences from the method for manufacturing the display assembly 10 of
The method for manufacturing the display assembly of this embodiment differs from the method for manufacturing the display assembly 10 of
For example, during the step of coating, the internal face 30B of the translucent part of the support 30 is coated with the decorative coating 36.
For example, in this case, the step of coating comprises printing or spraying the translucent part of the support 30 with the decorative coating 36 for obtaining the visual appearance imitation portion 32P of the decorative layer 32. For example, the visual appearance imitation portion 32P reproduces the acquired image of the predefined material 22 or the filtered acquired image of the predefined material 22.
The method for manufacturing the display assembly of this embodiment thus differs from the method for manufacturing the display assembly 10 of
