Display device having a variable thickness covering
The invention relates to a display device comprising a display plane, on which one or more planar display regions 10, 11 are arranged, said planar regions 10, 11 being covered by transparent coverings. A single transparent covering 3 covers all the planar display regions 10, 11 of the display device, is formed three-dimensionally on the viewer's side by regions of differing thicknesses and is connected on the side facing away from the viewer to the planar display regions 10, 11 by means of optical bonding. The refractive index of the material of the covering 3 corresponds to the refractive index of the optical-bonding material 8.

wherein the regions of various thickness are located linearly between at least one of digits, characters, symbols dials, pointers, and an optoelectronic display located on the display plane and an observer location, and
wherein the transparent covering is connected, by its side which faces away from the observer side, to the planar display regions using optical bonding, with the refractive index of the material of the covering corresponding to the refractive index of the optical bonding material.

9. The display device as claimed in claim 1 , wherein the transparent covering is an injection-molded part.
10. The display device as claimed in claim 1 , characterized in that the transparent covering ( 3 ) has a thermoformed transparent film ( 12 ), the depressions ( 7 ) of which on the side facing away from an observer ( 4 ) are filled with optical bonding material ( 8 ).
11. The display device as claimed in claim 1 , wherein the transparent covering is a tinted covering.
12. A display device comprising:
at least one planar display regions arranged in a display plane;
a single transparent covering that covers all of the at least one planar display regions of the display device, wherein the covering is three-dimensionally having regions of various thicknesses;
wherein the regions of various thicknesses are in a position visible to an observer location such that a line of sight for an observer passes through the transparent covering when viewing the at least one planar display and the at least one display region is optically perceived by the observer as being elevated in the regions of greater thickness; and
wherein the regions of various thickness are located linearly between at least one of digits, characters, symbols dials, pointers, and an optoelectronic display located on the display plane and the observer location.
13. A display device comprising:
at least one planar display regions arranged in a display plane;
a single transparent covering that covers all of the at least one planar display regions of the display device, wherein the covering is three-dimensionally having regions of various thicknesses;
wherein the regions of various thicknesses are between the at least one planar display region and an observer location on the observer side of the transparent covering such that the at least one display region is optically perceived as being elevated toward the observer side in the regions of greater thickness; and
wherein the regions of various thickness are located in a line of sight between at least one of digits, characters, symbols dials, pointers, and an optoelectronic display located on the display plane and the observer location.
