Spot Facing

Adding a tactile dip to a display surface to give the illusion of 3D touch

This technique can be applied to a touch panel, in particular for features such as buttons, dials, or sliders. This enables adding a tactile dimension to the user experience and can also be employed to engrave a logo or brand name in the coverlens.

Unlike mechanical engraving, spot facing leaves a smooth edge, free from burrs, and hence requires no further machining or polishing to be safe for the user to touch. The engraved surface remains transparent thereby allowing the user to see graphics or icons clearly when displayed behind the cover.

Spot-faced features can be of any shape, and the strength of the glass is not compromised.
