12 . The cover glass and frame system of claim 1 , further comprising an air gap between the display module and the glass substrate.

13 . The cover glass and frame system of claim 1 , wherein the frame and the glass substrate are attached to form an integral unit that experience substantially the same stresses as one another, before, during and after an impact on either one or both of the frame and the glass substrate.

14 . The cover glass and frame system of claim 13 , wherein, the maximum stress exhibited by the frame caused by an impact on a portion of the second frame surface is within 10% of the maximum stress exhibited by the glass substrate measured across a portion of the first major surface adjacent to the portion of the second frame surface.
