Abstract
A seamless three-dimensional cover (1) for an electronic device (2), the seamless three-dimensional cover (1) comprising of at least one glass base layer (3) and at least one glass rim layer (4). At least one layer of color inducing film (5) is arranged between at least one of the base layer (3) and the rim layer (4), or between two adjacent rim layers (4). The base layer (3), the rim layer(s) (4), and the layer of color inducing film (5) are fused together to form the seamless three-dimensional cover (1). This facilitates a strong and durable three-dimensional cover, which cover is translucent as well as at least partially colored. Furthermore, the cover does not affect the function of components such as millimeter-wave antennas.
Claims19
A method of manufacturing a seamless three-dimensional cover for an electronic device, the method comprising steps of:
- providing a first flat sheet of transparent glass;
- depositing a first layer of color inducing film on the first flat sheet of transparent glass, wherein the first layer of color inducing film bonds to the first flat sheet of transparent glass during the depositing, and the first layer of color inducing film encircles a point of the first flat sheet of transparent glass and does not cover the point of the first flat sheet of transparent glass;
- providing a second flat sheet of transparent glass on top of the first layer of color inducing film, wherein the second flat sheet of transparent glass encircles the point of the first flat sheet of transparent glass and does not cover the point of the first flat sheet of transparent glass;
- fusing the first flat sheet of transparent glass, the first layer of color inducing film and the second flat sheet of transparent glass to form a seamless three-dimensional material, wherein after the fusing the first layer of color inducing film is fused to the first flat sheet of transparent glass and the second flat sheet of transparent glass;
- and
- machining the seamless three-dimensional material to form the seamless three-dimensional cover.
