A transparent article, such as a transparent cover, for use as a cover glass for an electronic device, as well as methods for producing transparent articles, are disclosed. The transparent article can form a part of a housing of the portable electronic device and can provide an outer surface for a portion of the housing. The transparent article can be provided over a display of portable electronic device to provide a protective outer cover over the display. In one embodiment, the transparent article can be formed with a laminate structure. In another embodiment, the transparent article can be formed with a ribbed structure. In still another embodiment, a sapphire coating can be deposited on the transparent article to improve it strength. Advantageously, the transparent article is able to be not only thin and lightweight but also provide sufficient stiffness for use as a cover glass.

1. A portable consumer electronic product, comprising: a glass user interfacing part, the glass user interfacing part including at least: an outer layer of glass having a thickness of less than or equal to 0.4 mm, andat least two inner ribs that provide structural support for the outer layer, the at least two inner ribs extending linearly, horizontally and vertically across an image display portion and a non-image display portion of an inner surface of the glass user interfacing part, and the at least two inner ribs being substantially transparent;a display provided internal to the portable consumer electronic device and behind the glass user interfacing part; anda processor operable to control information display on the display. 2. The portable consumer electronic product as recited in claim 1, wherein the at least two inner ribs is part of an inner layer of the inner surface of the glass user interfacing part, and wherein the inner layer is formed of the least two inner ribs and a substantially transparent filler material that is filled in around the at least two inner ribs. 3. The portable consumer electronic product as recited in claim 2, wherein a first index of refraction of the substantially transparent filler material is substantially matched with a second index of refraction of the at least two inner ribs. 4. The portable consumer electronic product as recited in claim 3, wherein the substantially transparent filler material comprises substantially clear adhesive. 5. The portable consumer electronic product as recited in claim 3, wherein the at least two inner ribs comprise glass or fiberglass. 6. A portable consumer electronic product, comprising: a display;a housing, comprising: a glass user interfacing part forming at least part of an exterior surface of the housing, comprising: a glass layer having a thickness of less than or equal to 0.4 mm; andan array of substantially transparent ribs attached to the glass layer,wherein: the glass user interfacing part is positioned over the display;the array of substantially transparent ribs extend across an image display portion of the glass layer located over the display; andthe array of substantially transparent ribs extend across a non-image display portion of the glass layer located outside of a peripheral portion of the display. 7. The portable consumer electronic product as recited in claim 6, wherein the array of substantially transparent ribs comprises a glass material. 8. The portable consumer electronic product as recited in claim 6, wherein the array of substantially transparent ribs comprises a fiberglass material. 9. The portable consumer electronic product as recited in claim 6, further comprising: a substantially transparent filler material that is filled in around the array of substantially transparent ribs. 10. The portable consumer electronic product as recited in claim 9, wherein a first index of refraction of the substantially transparent filler material is substantially matched with a second index of refraction of the array of substantially transparent ribs. 11. The portable consumer electronic product as recited in claim 1, further comprising: a layer of adhesive attaching the array of substantially transparent ribs to the glass layer. 12. The portable consumer electronic product as recited in claim 11, wherein the array of substantially transparent ribs, the substantially transparent filler material, and the layer of adhesive are each comprised of different materials. 13. The portable consumer electronic product as recited in claim 6, the housing, further comprising: a housing structure forming at least a portion of the outer surface of the portable consumer electronic product, wherein: the glass user interfacing part is coupled to the housing structure to define an inner volume; and the display is positioned within the inner volume and attached to an inner surface of the glass user interfacing part. 14. A portable consumer electronic product, comprising: a glass user interfacing part, the glass user interfacing part including at least: a top layer of glass having a thickness of less than or equal to 0.4 mm;an intermediate layer of adhesive; anda bottom layer of substantially clear material adhered to a bottom surface of the top layer via the intermediate layer of adhesive;a display provided internal to the portable consumer electronic device and below the glass user interfacing part; anda processor operable to control information display on the display,wherein the bottom layer includes at least two inner ribs providing structural support for the top layer extending linearly, horizontally and vertically across an image display portion over the display and a non-image display portion of the glass user interfacing part, and the at least two inner ribs being substantially transparent. 15. The portable consumer electronic product as recited in claim 14, wherein the bottom layer of substantially clear material has a thickness of less than or equal to 0.4 mm. 16. The portable consumer electronic product as recited in claim 14, wherein the intermediate layer of adhesive is attached to and surrounding the at least two inner ribs. 17. The portable consumer electronic product as recited in claim 14, wherein the relative density of the intermediate layer of adhesive is significantly less than the relative density of the top layer of glass or the bottom layer of substantially clear material. 18. The portable consumer electronic product as recited in claim 14, wherein a first index of refraction of the intermediate layer of adhesive, a second index of refraction of the top layer of glass, a third index of refraction of the bottom layer, and a fourth index of refraction of the at least two inner ribs are substantially matched. 19. The portable consumer electronic product as recited in claim 14, the glass user interfacing part, further comprising: a substantially transparent filler material, the substantially transparent filler material surrounding the at least two inner ribs. 20. The portable consumer electronic product as recited in claim 19, wherein the intermediate layer of adhesive, the substantially transparent material, and the at least two inner ribs are each comprised of different materials.
