Abstract

A touch-screen panel may include a first touch-screen portion, a second touch-screen portion, and a third touch-screen portion. The first portion may include a first transparent electrode set. The second portion may include a second transparent electrode set, may abut the first portion at a first boundary, and may be oriented at a first angle with respect to the first portion. The third portion may include a third transparent electrode set, may abut the first portion at a second boundary, and may be oriented at a second angle with respect to the first portion. A length of the second portion in a direction parallel to the first boundary may be less than a sum of a length of the first portion in the direction parallel to the first boundary and a width of the third portion in a direction perpendicular to second boundary.

First claim

What is claimed is:

1. An electronic device comprising:
a curved touch-screen panel having a shape bent with respect to a first axis and bent with respect to a second axis that intersects with the first axis, the curved touch-screen panel comprising an intersection at which the first axis intersects with the second axis, wherein the intersection is spaced from vertices of a removal region before the removal region is removed from the curved touch-screen panel; and
a body to which the curved touch-screen panel is attached.

2. The electronic device of claim 1 , wherein the curved touch-screen panel is divided into a center remaining region and an outer remaining region by the first axis and the second axis, and a transparent electrode pattern of the center remaining region is identical to a transparent electrode pattern of the outer remaining region.

3. The electronic device of claim 2 , wherein the center remaining region includes N transparent electrode pattern lines, where N is an integer greater than or equal to 1, and the outer remaining region includes M transparent electrode pattern lines, where M is an integer greater than or equal to 1.

4. The electronic device of claim 3 , wherein an electrode pitch of the center remaining region is the same as an electrode pitch of the outer remaining region.

5. The electronic device of claim 1 , wherein the curved touch-screen panel is divided into a center remaining region and an outer remaining region by the first axis and the second axis, and a transparent electrode pattern of the center remaining region is different from a transparent electrode pattern of the outer remaining region.

6. The electronic device of claim 5 , wherein the center remaining region includes N transparent electrode pattern lines, where N is an integer greater than or equal to 1, and the outer remaining region includes M transparent electrode pattern lines, where M is an integer greater than or equal to 1.

7. The electronic device of claim 6 , wherein an electrode pitch of the center remaining region is the same as an electrode pitch of the outer remaining region.

8. The electronic device of claim 6 , wherein an electrode pitch of the center remaining region is different from an electrode pitch of the outer remaining region.

9. The electronic device of claim 1 , wherein the curved touch-screen panel includes a first transparent electrode layer having a structure in which first transparent electrode patterns are connected in a first direction and a second transparent electrode layer having a structure in which second transparent electrode patterns are connected in a second direction that is perpendicular to the first direction.

10. The electronic device of claim 1 , wherein the curved touch-screen panel includes a single transparent electrode layer having a structure in which first transparent electrode patterns are connected in a first direction and second transparent electrode patterns are connected using bridges in a second direction that is perpendicular to the first direction.

11. The electronic device of claim 1 , further comprising:
a curved display panel combined with the curved touch-screen panel, the curved display panel being manufactured to have a shape that is substantially identical to the shape of the curved touch-screen panel.

12. A method of manufacturing a curved touch-screen panel comprising:
preparing a flat touch-screen panel;
determining a first axis and a second axis that intersects with the first axis based on a target shape of a curved touch-screen panel;
removing a removal region, wherein vertices of the removal region is spaced from an intersection at which the first axis intersects with the second axis before the removing; and
bending the flat touch-screen panel with respect to the first axis and the second axis to form the target shape of the curved touch-screen panel.
