Abstract
A laser-textured glass cover member suitable for use in an electronic device is disclosed. The laser-textured surface of the glass cover member may provide a smooth feel to an external surface of the electronic device without introducing a perceptible visual texture. Methods for making the laser-textured glass cover members are also disclosed.
Claims12
An electronic device comprising:
- an enclosure at least partially defining an internal volume of the electronic device, the enclosure including a cover assembly comprising:
- a glass cover member defining:
- an exterior surface and an interior surface;
- and
- laser-formed features along the exterior surface and resulting from ablation and flow of the glass cover member, the laser-formed features defining peaks having a mean peak curvature (Ssc) from about 0.1 microns−1 to about 1.2 microns−1;
- and
- a decorative coating disposed along the interior surface and viewable through the laser-formed features of the glass cover member.
4 more elements
An electronic device, comprising:
- an enclosure;
- a display positioned at least partially within the enclosure;
- a first glass cover member coupled to the enclosure and defining a transparent portion positioned over the display;
- and
- a second glass cover member coupled to the enclosure and including a laser-textured surface defining an irregular set of hills and valleys, the irregular set of hills and valleys having:
- a mean peak spacing from about 1 micron to about 15 microns;
- and
- a root mean square surface height (Sq) from about 0.1 micron to about 1.5 microns.
