Abstract

An electronic device having a cover glass secured with a frame is disclosed. The electronic device includes a masking layer positioned between the cover glass and the frame. The masking layer may include several ink layers. The pigment composition of one of the ink layers may be altered in order to improve an adhesive bond between the ink layer and the cover glass. The frame can be modified to enhance an adhesive bond between the masking layer and the frame. For example, the frame can be altered to include a porous region to increase the surface area of the frame such that the adhesive can bond to the additional surface area. The frame may also include an extension, or rib, that may increase the surface area of the frame that receives an adhesive. The frame may include an opening or a cavity that assists in assembly between an insert-molded feature.

First claim

What is claimed is:

1 . An electronic device having a first part and a second part secured with the first part, the electronic device comprising:
a masking layer positioned at an interface between the first part and the second part to prevent light transmission through the interface, the masking layer comprising:
a first layer including a first composition having a first type pigment, and
a second layer including a second composition having the first type pigment, the second composition different from the first composition.

2 . The electronic device of claim 1 , wherein:
the first composition comprises the first type pigment and a first amount of resin, and the second composition comprises the first type pigment and a second amount of resin less than the first amount of resin.

3 . The electronic device of claim 2 , wherein the first layer is secured with the first part.

4 . The electronic device of claim 3 , wherein the first part comprises a protective cover that includes a transparent material, and wherein the second part comprises a cover support member that receives the protective cover.

5 . The electronic device of claim 4 , further comprising an adhesive layer between the masking layer and the cover support member, wherein the cover support member comprises a porous region, and wherein the adhesive layer is at least partially disposed in the porous region.

6 . The electronic device of claim 5 , further comprising:
a display assembly; and a display frame, wherein the display assembly and the display frame are covered by the protective cover, and wherein the display frame includes a color resembling a color associated with the first type pigment.

7 . The electronic device of claim 1 , further comprising an adhesive layer between the masking layer and the second part wherein:
the second part comprises a rib having a first surface, a second surface, and a third surface, and the adhesive layer is disposed on the first surface, the second surface, and the third surface.

8 . An electronic device having a display assembly and a display frame bordering the display assembly, the electronic device comprising:
a protective cover assembly overlaying the display assembly and the display frame; a cover support member having a support surface that receives an adhesive layer to secure the cover support member with the protective cover, the support surface having a porous region that receives the adhesive layer; and a masking layer positioned at an interface between the protective cover and the cover support member to prevent light transmission through the interface.

9 . The electronic device of claim 8 , wherein the support surface comprises a primer agent disposed on the support surface that alters the support surface to form the porous region.

10 . The electronic device of claim 8 , wherein the support surface comprises a rib formed on the support surface, the rib including a first surface and a second surface perpendicular to the first surface.

11 . The electronic device of claim 10 , wherein the adhesive layer is disposed on the first surface and the second surface.

12 . The electronic device of claim 11 , wherein the rib further comprises a third surface different from the first surface and the second surface, wherein the adhesive is disposed on the third surface.

13 . The electronic device of claim 8 , wherein the support surface comprises a series of peaks and valleys, and wherein the adhesive layer is disposed on the series of peaks and valleys.

14 . The electronic device of claim 8 , wherein the masking layer is directly secured to the protective cover, and wherein the masking layer comprises:
a first layer including a first composition having a first type pigment, and a second layer including a second composition having the first type pigment, the second composition different from the first composition.

15 . The electronic device of claim 14 , wherein:
the first composition comprises the first type pigment and a first amount of resin, and the second composition comprises the first type pigment and a second amount of resin less than the first amount of resin.

16 . A method for assembling an electronic device having a first part and a second part secured with the first part, the method comprising:
disposing a first layer along the first part, the first layer including a first composition having a first type pigment; and disposing a second layer on the first layer, the second layer including a second composition having the first type pigment, the second composition different from the first composition, wherein the first layer and the second layer combine to define a masking layer at an interface between the first part and the second part to prevent light transmission through the interface.

17 . The method of claim 16 , wherein disposing the masking layer comprises:
forming the first composition with the first type pigment and a first amount of resin, and forming the second composition comprises the first type pigment and a second amount of resin less than the first amount of resin.

18 . The method of claim 16 , further comprising:
forming a porous region on the second part; and applying an adhesive layer to the second part, wherein the adhesive layer is at least partially disposed in the first part.

19 . The method of claim 16 , further comprising:
forming a series of peaks and valleys on the second part; and applying an adhesive layer to the second part, wherein the adhesive layer is at least partially disposed on the series of peaks and valleys.

20 . The method of claim 16 , further comprising providing a display frame that includes a color resembling a color associated with the first type pigment.
