Abstract

An electronic device having two or more opposing sides is disclosed. The electronic device comprises a display module, a window on the display module, and a frame at least partly surrounding the display module. The frame comprises, at two or more opposing sides of the electronic device, a side portion and an upper portion extending a determined distance from the side portion towards the opposing side of the electronic device and ending at an inner edge defining an opening having a width smaller than the width of the display module. The display module has an active area and an inactive area. The display module is disposed within the frame so that at least a part of the inactive area is disposed below and covered by the upper portion, at least a part of the active area being visible through the opening. The window is disposed in the opening.

the window is laminated to the display module using a layer of cured optically clear resin extending between the display module and the window, thereby attaching the window to the display module; and

the layer of cured optically clear resin extends into a gap between the display module and the upper portion of the frame.

2. The electronic device as defined in claim 1, wherein at least a part of the inactive area is disposed below and covered by the upper portion of the frame so that the upper portion extends over the inactive area at at least one side of the electronic device towards the opposing side of the electronic device to a distance of 0.2 mm from the active area or further, so that at most 0.2 mm of the inactive area at the at least one side of the electronic device is visible through the opening.

3. The electronic device as defined in claim 2, wherein the active area and the inactive area are divided by a boundary, and the boundary is in alignment with the inner edge of the upper portion.

4. The electronic device as defined in claim 1, wherein a portion of the layer of cured optically clear resin extends into a gap between the window and the inner edge of the upper portion of the frame;

and

wherein a larger portion of the layer of cured optically clear resin extends between the display module and the upper portion of the frame than between the window and the inner edge of the upper portion of the frame.

5. The electronic device as defined in claim 1, wherein the layer of cured optically clear resin extends between the display module and the side portion.

6. The electronic device as defined in claim 1, wherein the window has an upper surface, and the upper portion has an upper edge;

and the upper surface of the window is flush with the upper edge of the upper portion.

7. The electronic device as defined in claim 1, wherein the window has a width, and the entire width of the window is transparent.

8. An electronic device having two or more opposing sides, the electronic device comprising a frame and a display module, the frame at least partially surrounding the display module;

the display module having an active area and an inactive area adjacent to the active area and at the periphery of the display module;

the frame comprising a side portion and an upper portion on an upper side of the electronic device, the upper portion extending a determined distance from the side portion towards the active area of the display module and ending at an inner edge of the upper portion; and

wherein

at least a part of the inactive area at at least one side of the electronic device is disposed below and covered by the upper portion of the frame so that the upper portion extends over the inactive area at at least one side of the electronic device towards the active area to a distance of 0.2 mm from the active area or further, so that

the entire active area and at most 0.2 mm of the inactive area at the side of the electronic device are visible, or at least a part of the active area is visible.

9. The electronic device as defined in claim 8, wherein the active area and the inactive area are divided by a boundary, and the boundary is in alignment with the inner edge of the upper portion.

10. The electronic device as defined in claim 8, wherein the electronic device has two or more opposing sides, and the display module has a width and a length,

the frame comprising, at two or more opposing sides of the electronic device, a side portion and an upper portion on an upper side of the electronic device, the upper portion extending a determined distance from the side portion towards the opposing side of the electronic device and ending at an inner edge of the upper portion, and the inner edge of the upper portion defining an opening having a width smaller than the width of the display module;

wherein

the display module is disposed within the frame so that at least a part of the inactive area is disposed below and covered by the upper portion of the frame, at least a part of the active area being visible through the opening, so that the upper portion extends over the inactive area at at least one side of the electronic device towards the opposing side of the electronic device to a distance of 0.2 mm from the active area or further, so that at most 0.2 mm of the inactive area at the at least one side of the electronic device is visible through the opening.

11. The electronic device as defined in claim 10, wherein the active area of the display module has a width substantially equal to or greater than the width of the opening.
