Samsung patents back glass that changes thickness for a smooth color fade

Samsung describes a design for the back cover of an electronic device that uses a piece of colored glass with varying thickness. The glass is thicker in the center and gradually gets thinner toward the edges to create a smooth visual transition. This glass sits on top of an adhesive layer and a printed backing layer.

Why it mattersThis design allows manufacturers to create a more seamless, gradient-like look on the back of phones or tablets without relying solely on printed patterns.

In the filing’s own words

According to various embodiments of the disclosure, an electronic device may comprise a cover glass covering at least a first surface. The cover glass may include a color glass including an end having a first thickness and an end having a second thickness different from the first thickness and configured to sequentially vary in thickness from the first thickness to the second thickness, an attaching layer disposed under the color glass and including a shape corresponding to the sequentially varying shape of the color glass, and a printed layer disposed under the attaching layer.

What exactly they claim (claim 1)

1. An electronic device comprising: a housing; a front cover glass defining at least a portion of a front exterior surface of the electronic device; and a rear cover glass defining at least a portion of a rear exterior surface of the electronic device; wherein the rear cover glass includes: a color glass including a first portion having a first thickness and a second thickness greater than the first thickness, and varying in thickness from the first thickness to the second thickness, the first portion being disposed at least at an area of the color glass distal from an edge portion of the housing, a second portion having the first thickness and disposed between the first portion and an edge portion of the housing, and a third portion having the second thickness and disposed on an opposite side of the first portion from the edge portion of the housing; wherein the first portion is disposed between the second portion and the third portion and, wherein the second portion and the third portion face substantially the same direction, an attaching layer disposed under the color glass; and a printed layer disposed under the attaching layer.
