Abstract

Methods and apparatus provide for an improved visual and optionally tactile features on a visible element of an article, such as a consumer electronic device (e.g., a mobile electronic device, a mobile phone, a smartphone, a tablet, a phablet, a notebook computer, a laptop, etc.).

First claim

The invenion claimed is:

1. An apparatus, comprising:
a substrate comprising a first major surface, a second major surface opposite the first major surface, and at least one edge surface extending between the first and second major surfaces, the substrate comprising an at least partially transparent material;
at least one visual element disposed on the second major surface of the substrate and/or within the substrate such that the at least one visual element may be viewed through the first major surface; and
at least one tactile element disposed on the first major surface of the substrate, the at least one tactile element comprising one or more surface roughness portions,
wherein at least some of the one or more surface roughness portions of the tactile element are positioned on the first major surface of the substrate in a complimentary fashion with respect to at least some of the one or more visual portions of the visual element to modify the visual effect of the visual element as viewed through the first major surface of the substrate.

2. The apparatus of claim 1 , wherein at least some of the one or more surface roughness portions of the tactile element are positioned on the first major surface of the substrate in substantial registration with at least some of the one or more visual portions of the visual element.

3. The apparatus of claim 1 , wherein:
the one or more visual portions of the visual element comprise a first visual portion;
the one or more surface roughness portions of the tactile element comprise a first roughness portion;
the first roughness portion is positioned on the first major surface of the substrate in the visually complimentary fashion with respect to the first visual portion; and
the first roughness portion is defined by one of: (i) an area of relatively higher surface roughness that is positioned in the visually complimentary fashion bordered by at least one area of relatively lower surface roughness, and (ii) an area of relatively lower surface roughness that is positioned in the visually complimentary fashion bordered by at least one area of relatively higher surface roughness.

4. The apparatus of claim 1 , wherein:
a majority of a total surface area of the first major surface of the substrate comprises a first surface roughness;
the one or more surface roughness portions of the tactile element cover a minority of the total surface area of the first major surface and comprise at least some portions that are of a second surface roughness, which is different from the first surface roughness.

5. The apparatus of claim 1 , wherein the second surface roughness is relatively rougher than the first surface roughness.

6. The apparatus of claim 1 , wherein the first surface roughness is relatively rougher than the second surface roughness.

7. The apparatus of claim 1 , wherein the substrate comprises one of glass, glass ceramic material, and polymer material.

8. The apparatus of claim 7 , wherein the substrate comprises strengthened glass.

9. The apparatus of claim 1 , the at least one visual element comprising one or more visual portions arranged into at least one of: (i) one or more areas of color, (ii) one or more lines, (iii) one or more patterns, (iv) one or more designs, (v) one or more images, and (vi) one or more combinations thereof, and the surface roughness portions arranged into at least one of: (i) one or more areas of surface roughness, (ii) one or more lines of surface roughness, (iii) one or more patterns of surface roughness, (iv) one or more designs of surface roughness, and (v) one or more combinations thereof.

10. A consumer electronic product, comprising:
a housing having a front surface, a back surface and side surfaces;
electrical components provided at least partially within the housing, the electrical components including at least a controller, a memory, and a display, the display being provided at or adjacent the front surface of the housing; and
a cover substrate disposed over the display,
wherein at least one of a portion of the housing or the cover substrate comprises the apparatus of claim 1 .

11. An apparatus, comprising:
a substrate comprising a first major surface, a second major surface opposite the first major surface, and at least one edge surface extending between the first and second major surfaces, the substrate comprising an at least partially transparent material;
at least one visual element disposed on the second major surface of the substrate and/or within the substrate such that the at least one visual element may be viewed through the first major surface; and
at least one tactile element disposed on the first major surface of the substrate, the at least one tactile element comprising one or more surface element portions of differing heights,
wherein at least some of the one or more surface element portions of the tactile element are positioned on the first major surface of the substrate in a complimentary fashion with respect to at least some of the one or more visual portions of the visual element to modify the visual effect of the visual element as viewed through the first major surface of the substrate.

12. The apparatus of claim 11 , wherein at least some of the one or more surface element portions of the tactile element are positioned on the first major surface of the substrate in substantial registration with at least some of the one or more visual portions of the visual element.

13. The apparatus of claim 11 , wherein:
the one or more visual portions of the visual element comprise a first visual portion;
the one or more surface element portions of the tactile element comprise a first surface element portion;
the first surface element portion is positioned on the first major surface of the substrate in the visually complimentary fashion with respect to the first visual portion; and
the first surface element portion is defined by one of: (i) an area of relatively higher surface height that is positioned in the visually complimentary fashion bordered by at least one area of relatively lower surface height, and (ii) an area of relatively lower surface height that is positioned in the visually complimentary fashion bordered by at least one area of relatively higher surface height.

14. The apparatus of claim 11 , wherein:
a majority of a total surface area of the first major surface of the substrate comprises a first surface height;
the one or more surface element portions of the tactile element cover a minority of the total surface area of the first major surface and comprise at least some portions that are of a second surface height, which is different from the first surface height.

15. The apparatus of claim 11 , wherein the second surface height is relatively higher than the first surface height.

16. The apparatus of claim 11 , wherein the first surface height is relatively higher than the second surface height.

17. The apparatus of claim 11 , wherein the substrate comprises one of glass, glass ceramic material, and polymer material.

18. The apparatus of claim 11 , wherein the substrate comprises strengthened glass.

19. The apparatus of claim 11 , the at least one visual element comprising one or more visual portions arranged into at least one of: (i) one or more areas of color, (ii) one or more lines, (iii) one or more patterns, (iv) one or more designs, (v) one or more images, and (vi) one or more combinations thereof, and the one or more surface element portions of differing heights arranged into at least one of: (i) one or more areas o
