1. A method for assembling an electronic product comprising:
- obtaining a cover glass having an outward facing surface and an inner facing surface;
selectively chemically strengthening one surface region of the outward facing surface of the cover glass differently than chemically strengthening an other surface region of the outward facing surface of the cover glass, the one surface region located at a periphery of the cover glass and having a width less than the width of the other surface region which is not at the periphery of the cover glass; and
subsequently attaching the cover glass to a housing for the electronic product such that the outward facing surface of the cover glass remains at least partially exposed,wherein the one surface region and the other surface region are both different portions of the outward facing surface of the cover glass, andwherein the enhanced strengthening of the one surface region comprises both;
a) disposing the one surface region in a first heated solution for a first period of time, so as to allow at least one component of the first heated solution to diffuse into the one surface region, and b) thereafter disposing the one surface region in a second heated solution for a second period of time, so as to allow at least one component of the second heated solution to diffuse into the one surface region.

8. A method for assembling an electronic product comprising:
-
obtaining a display cover glass having front, back and side surfaces; shielding a portion of the front surface of the display cover glass, the shielding providing the front surface of the display cover glass with at least one shielded portion and at least one unshielded portion, the shielded portion shielding a center region of the display cover glass and wherein the at least one unshielded portion comprises at least an edge extremity of the display cover glass, and wherein the at least one unshielded portion has a width between two to ten millimeters; chemically strengthening the at least one unshielded portion of the front surface of the display cover glass; arranging the display cover glass with a substantially full view display area that consumes a majority of a front surface of the electronic device, wherein the arranging avoids optically interfering with viewing of the substantially full view display area through the display cover glass; and subsequently attaching the display cover glass to a housing for the electronic product. - View Dependent Claims (9, 10, 11, 12)

13. A method for assembling an electronic product comprising:
-
chemically strengthening a cover glass defining an outward facing planar surface and an edge surface, including strengthening a peripheral portion of the outward facing planar surface and the edge surface; further chemically strengthening the peripheral portion of the outward facing planar surface by; shielding a portion of the cover glass, thereby defining; a shielded portion shielding a center portion of the outward facing planar surface; and an unshielded portion including the peripheral portion of the outward facing planar surface, and applying an additional chemical strengthening to the cover glass, thereby providing enhanced strengthening of the peripheral portion as compared to the center portion; and attaching the cover glass to a housing for the electronic product. - View Dependent Claims (14, 15)

16. A method for assembling an electronic product comprising:
-
obtaining a cover glass having a single layer of glass, the cover glass including at least one aperture; selectively chemically strengthening one surface region of the cover glass differently than chemically strengthening an other surface region of the cover glass, the one surface region positioned at a periphery of the cover glass and having a first width, the other surface region located at a non-periphery region of the cover glass; and subsequently attaching the cover glass to a housing for the electronic product, wherein when the cover glass is attached to the housing, an outer top surface of the cover glass remains substantially exposed, and wherein the one surface region and the other surface region are both different portions of the outer top surface of the cover glass, and serve as at least a portion of a front surface of the housing for the electronic product, and wherein the other surface region comprises an aperture periphery region disposed around the at least one aperture in the cover glass. - View Dependent Claims (17)
