Abstract
An electrode pattern includes unit patterns having a mesh-shape, the unit patterns connected to each other and including a first unit pattern and a second unit pattern, in which each of the first and second unit patterns includes sides connected to each other, an area of the first unit pattern is smaller than an area of the second unit pattern, and at least one side of the first unit pattern has a line width smaller than a line width of one side of the second unit pattern.
Claims19
An electrode pattern, comprising:
- unit patterns having a mesh-shape, the unit patterns connected to each other,
- wherein:
- each of the unit patterns comprises sides connected to each other;
- the unit patterns are divided into a first group in which each of the unit patterns has an area that is smaller than a predetermined value, and a second group in which each of the unit patterns has an area that is greater than the predetermined value;
- and
- at least one side of each of the unit patterns of the first group has a line width smaller than a line width of a side of the unit pattern of the second group.
An electrode pattern, comprising:
- unit patterns having a mesh-shape, the unit patterns connected to each other,
- wherein:
- each of the unit patterns comprises sides connected to each other;
- the unit patterns are divided into a first group in which each of the unit patterns has an angle formed by two adjacent sides that is smaller than a predetermined value, and a second group in which each of the unit patterns has an angle formed by two adjacent sides that is greater than the predetermined value;
- and
- at least one of the two adjacent sides of the unit pattern of the first group has a line width smaller than a line width of any of the two adjacent sides of the second unit pattern of the second group.
A touch panel, comprising:
- a first substrate;
- and
- an electrode pattern disposed on a first surface the first substrate, the electrode pattern comprising irregular polygonal unit patterns connected to each other,
- wherein:
- the irregular polygonal unit patterns have a mesh-shape;
- each of the irregular polygonal unit patterns comprises sides connected to each other;
- the irregular polygonal unit patterns are divided into a first group in which each of the irregular polygonal unit patterns has an area that is smaller than a first predetermined value, and a second group in which each of the irregular polygonal unit patterns has an area that is greater than the first predetermined value;
- and
- at least one side of the irregular polygonal unit pattern of the first group has a line width smaller than a line width of a side of the irregular polygonal unit pattern of the second group.
A method for forming an electrode pattern, the method comprising:
- determining a shape of an irregular electrode pattern, the irregular electrode pattern comprising a unit pattern;
- calculating an area of the unit pattern;
- comparing the area of the unit pattern with a reference value;
- reducing a line width of at least one side of the unit pattern, when the area of the unit pattern is smaller than the reference value;
- and
- forming the electrode pattern on a first surface of a first substrate according to the shape and the line width of the unit pattern,
- wherein the line width of each sides of the unit pattern is maintained, when the area of the unit pattern is equal to or greater than the reference value.
