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.

Electronic devices including laser-textured glass cover members

Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder includes a spindle and an encoded pattern disposed around a circumference of the spindle. The encoded pattern may include one or more surface features that create a direction-dependent reflective region.

Watch with rotatable optical encoder having a spindle defining an array of alternating regions extending along an axial direction parallel to the axis of a shaft

A method for co-finishing surfaces bonds a first structure formed of a first material and having a first surface in an aperture defined in a second structure formed of a second material and having a second surface such that there is an offset between the first surface and the second surface. The first surface and the second surface are co-lapped to reduce the offset. The first surface and second surface are co-polished to further reduce the offset. The first surface and second surfaces may then be flush. Edges of the first surface may be chamfered to mitigate damage during co-lapping and/or co-polishing. Fill material may be positioned in gaps between the first and second structures to mitigate damage during co-lapping and/or co-polishing.
