Abstract

An electronic device having a touch screen or display to reduce or eliminate visibility of structures in the device due to reflected light includes a base member and a touch member disposed on one surface of the base member and including first and second sensor parts spaced apart from each other with a boundary interposed therebetween. Each of the first and second sensor parts includes first and second areas disposed adjacent to each, a plurality of first patterns in the first area spaced apart from each other and a plurality of second patterns in the second area spaced apart from the first patterns. Each of the first patterns has a first shape, and each of the second patterns has a second shape different than the first shape. Various embodiments of patterns having shapes selected to reduce or eliminate visibility are disclosed.

First claim

a plurality of first patterns in the first area spaced apart from each other, each of the first patterns having a first shape; and
a plurality of second patterns in the second area spaced apart from the first patterns, each of the second patterns having a second shape different than the first shape.

2 . The electronic device of claim 1 , wherein the first shape is a substantially closed-loop shape and the second shape is a partially open shape.

3 . The electronic device of claim 2 , wherein at least one of the first and second patterns is a cut-away pattern.

4 . The electronic device of claim 1 , wherein the boundary is defined by the second area of the first sensor part and the second area of the second sensor part disposed adjacent to the second area of the first sensor part.

5 . The electronic device of claim 4 , wherein the first area has a shape defined by two sides extending in a first direction and two sides extending in a second direction intersecting the first direction, and the first patterns are arranged in a matrix form extending in the first and second directions.

6 . The electronic device of claim 5 , wherein the second area surrounds the first area.

7 . The electronic device of claim 5 , wherein the second patterns are aligned with the first patterns adjacent to the second patterns in the first direction or the second direction.

8 . The electronic device of claim 7 , wherein the second patterns of the first sensor part arranged in the first direction are aligned, in the second direction, with the second patterns of the second sensor part arranged in the first direction.

9 . The electronic device of claim 8 , wherein one of the second patterns has substantially the same shape and orientation as the shape and orientation as another one of the second patterns, the another one of the second patterns being adjacent to the first one of the second patterns.

10 . The electronic device of claim 8 , wherein one of the second patterns has a shape linearly symmetrical with the shape of another one of the second patterns, the another one of the second patterns being adjacent to the first one of the second patterns.

11 . The electronic device of claim 8 , wherein one of the second patterns has a shape substantially rotationally symmetrical with the shape of another one of the second patterns, the another one of the second patterns being adjacent to the one of the second patterns.

12 . The electronic device of claim 8 , wherein a first one of the second patterns has a shape symmetrical with a shape of another one of the second patterns by a point symmetry, the another one of the second cut-away patterns being adjacent to the first one of second patterns.

13 . The electronic device of claim 3 , further comprising a plurality of third patterns defined in the second areas, wherein at least some of the third patterns have a third shape different from the first and second shapes.

14 . The electronic device of claim 13 , wherein the third patterns are connected to respective ones of the second patterns.

15 . The electronic device of claim 14 , further comprising a plurality of fourth patterns defined in the second areas, wherein at least some of the fourth patterns have a fourth shape that is different than the first and second shapes and no portion of any of the fourth patterns is connected to any portion of any of the second or the third patterns in the second areas.

16 . The electronic device of claim 15 , wherein at least some of the plurality of fourth shapes have substantially the same shape as at least a portion of two connected sides of the first shape or the second shape.

17 . The electronic device of claim 13 , wherein the third patterns are adjacent to the boundary.

18 . The electronic device of claim 13 , wherein the second area comprises a plurality of protruding areas arranged spaced apart from each other.

19 . The electronic device of claim 18 , wherein first protruding areas are among the protruding areas of the first sensor part and protrude from the first sensor part toward the second sensor part, second protruding areas are among the protruding areas of the second sensor part and protrude from the second sensor part toward the first sensor part, and individual ones of the first protruding areas alternate with individual ones of the second protruding areas in a first direction or a second direction.

20 . The electronic device of claim 19 , wherein the boundary is defined along a junction between an outer side portion of the first protruding areas and an outer side portion of the second protruding areas.

21 . The electronic device of claim 20 , wherein a portion of the boundary is defined by the first protruding areas and the first area of the second sensor part adjacent to the first protruding areas, and another portion of the boundary is defined by the second protruding areas and the first area of the first sensor part adjacent to the second protruding areas.

22 . The electronic device of claim 19 , wherein each of the first and second protruding areas comprises a first sub-area in which at least one of the second patterns is located and a second sub-area in which at least one of the third patterns is located.
