Window and method of manufacturing the same
A manufacturing method of a window includes providing a window including a first non-folding portion, a second non-folding portion, and a folding portion disposed between the first and second non-folding portions and irradiating a laser beam to a front surface of the folding portion of the window to form a first groove in the front surface of the folding portion. The first and second non-folding portions and the folding portion are arranged in the window in a first direction, first processing areas extending in a second direction intersecting the first direction and arranged in the first direction are defined in the front surface of the folding portion, and the laser beam is irradiated at least once to each of the first processing areas in the second direction.
1 . A window comprising:
a first non-folding portion;
a second non-folding portion; and
a folding portion disposed between the first and second non-folding portions and provided with a first groove and a second groove which are respectively formed in a front surface and a rear surface of the folding portion, wherein
the first and second non-folding portions and the folding portion are arranged in a first direction,
each of the first and second grooves comprises a plurality of sub-grooves extending in a second direction,
the first and second grooves overlap in a third direction perpendicular to the first and the second direction, and
the plurality of sub-grooves forming the first groove overlap to form a wave pattern.
2 . The window of claim 1 , wherein the folding portion has a thickness that is equal to or smaller than about two-thirds (⅔) of a thickness of the first and second non-folding portions.
3 . A method of manufacturing a window, comprising:
providing a window comprising a first non-folding portion, a second non-folding portion, and a folding portion disposed between the first and second non-folding portions; and
irradiating a laser beam to a front surface of the folding portion of the window to form a first groove in the front surface of the folding portion, wherein
the first non-folding portion, the second non-folding portion, and the folding portion are arranged in the window in a first direction,
a plurality of first processing areas partially overlapping each other are defined in the front surface of the folding portion, and
the laser beam is sequentially irradiated to the plurality of first processing areas.
4 . A method of manufacturing a window, comprising:
providing a window comprising a first non-folding portion, a second non-folding portion, and a folding portion disposed between the first and second non-folding portions; and
irradiating a laser beam to a front surface of the folding portion of the window to form a first groove in the front surface of the folding portion, wherein
the first non-folding portion, the second non-folding portion, and the folding portion are arranged in the window in a first direction,
irradiating a laser beam includes irradiating a plurality of first processing areas in the front surface of the folding portion, the first processing areas extending in a second direction intersecting the first direction,
each of the plurality of first processing areas partially overlaps at least one other first processing area,
the laser beam is irradiated at least once to all of the folding portion, and
the first groove has a quadrangular shape or a circular shape when viewed in the first direction.
5 . The window of claim 1 , wherein the plurality of sub-grooves forming the second groove overlap to form a wave pattern.
