Abstract
Electronic devices including a textured component such as a cover member positioned over one or more components of the electronic device. Different surface regions of the textured component may be textured differently in order to provide optical contrast. For example, differently textured surface regions may differ in gloss, translucency, or both. In some cases the cover member defines a protruding feature and a surface region of the protruding feature is textured differently than an adjacent surface region.
Claims20
An electronic device comprising:
- a display;
- an enclosure at least partially surrounding the display and comprising:
- a front cover assembly including a front member positioned over the display;
- and
- a rear cover assembly including a chemically strengthened rear member, the chemically strengthened rear member defining:
- a base portion defining a base surface region;
- and
- a feature protruding with respect to the base surface region and defining a surface region having a texture comprising:
- a mean pitch from 10 microns to 40 microns, and
- a root mean square slope from 0.1 to 0.75;
- and
- a camera assembly including a camera module positioned at least partially in a hole formed through the feature.
An electronic device comprising:
- an enclosure including a cover assembly comprising:
- a glass member defining:
- a first exterior surface region having a first gloss value greater than 90 gloss units as measured at 60 degrees and defining a first texture having a first root mean square height less than 0.5 microns;
- and
- a second exterior surface region having a second gloss value less than 10 gloss units as measured at 60 degrees and defining a second texture having:
- a second root mean square height from 1 micron to 5 microns;
- and
- a mean pitch from 10 microns to 40 microns;
- and
- a coating disposed along an interior surface of the glass member.
An electronic device comprising:
- a display;
- an enclosure at least partially surrounding the display and comprising:
- a front cover assembly including a front member positioned over the display;
- and
- a rear cover assembly including a rear member comprising at least one of a glass or a glass ceramic, the rear member defining:
- a base region of an exterior surface of the rear member, the base region defining a first texture having:
- a first root mean square height from 1 micron to 5 microns;
- and
- a root mean square slope from 0.1 to 0.75;
- and
- a feature protruding with respect to the base region, the feature defining a plateau region of the exterior surface of the rear member, the plateau region having optical contrast with the base region and defining a second texture having a second root mean square height less than 0.25 microns;
- and
- a camera assembly including a camera module positioned at least partially within a hole formed in the feature.
