1. An electronic device comprising;
- a display stack including;
a coverglass with a top surface and a bottom surface, the top surface of the coverglass being etched to impart antiglare properties;
a touch layer contacted with the bottom surface of the coverglass;
a lightguide positioned beneath the coverglass and configured to receive light from a light source located adjacent to the lightguide;
a first optically clear adhesive (OCA) layer disposed between the bottom surface of the coverglass and a top surface of the lightguide, the first OCA layer including an acrylic OCA with a predetermined luminous transmittance rating and a silicone OCA with a predefined refractive index;
an electrophoretic display component positioned beneath the lightguide, the electrophoretic display component configured to display content;
a second OCA layer disposed between the lightguide and the electrophoretic display component; and
a ring adhesive disposed around an outer edge of the display stack, the ring adhesive extending from the top surface of the coverglass downward to a bottom surface of the lightguide;
a midframe disposed below the display stack; and
one or more elastically deformable foam components disposed between at least a portion of a bottom surface of the display stack and corresponding portions of a top surface of the midframe.

Abstract
Described herein are electronic devices that includes a display stack having a cover component atop a lightguide component and a display component below the lightguide component. In some instances, the cover component including an antiglare etching applied to a top surface of a coverglass and a touch pattern applied to a bottom surface of the coverglass. In some cases, an optically clear adhesive layer formed from two types of optically clear adhesive may be located between the cover component and the lightguide component and a ring adhesive may be applied to around an outer edge of the cover component, the optically clear adhesive and the lightguide component.
