Touch screen panel and method for manufacturing thereof
View Patent ↗A method for manufacturing a touch screen panel includes reinforcing a glass substrate, the glass substrate to be formed with a plurality of touch screen panels in unit cells, reinforcing the glass substrate including forming a reinforcing layer on an upper and a lower side of the glass substrate by performing a reinforcement treatment on a whole surface of the glass substrate, cutting the reinforced glass substrate in each unit cell, removing a part of the reinforcing layer formed in the upper and the lower side of the glass substrate adjacent to a cut cross section, performing a chemical HF treatment on a cross section of the glass substrate corresponding to the cut cross section and exposing the glass substrate by partially removing the reinforcing layer, and forming a touch screen panel per region of the unit cells, respectively.
1. A touch screen panel, comprising:
sensing patterns disposed at a first side of a glass substrate; and
an insulating layer disposed to cover the sensing patterns,
wherein the glass substrate has a reinforcing layer at the first side and at a second side, a part of the reinforcing layer of the first side and the second side of the glass substrate is removed, and an edge of a non-reinforced side that is exposed to a side of the glass substrate is implemented as a curved shape.
2. The touch screen panel as claimed in claim 1 , wherein the glass substrate having the reinforcing layer acts as a window, and the first side of the glass substrate is disposed in a direction facing a display panel.
3. The touch screen panel as claimed in claim 1 , further comprising an adhesive layer disposed on a side of the insulating layer, and a ground electrode layer disposed to be opposed to the insulating layer.
4. The touch screen panel as claimed in claim 1 , wherein the reinforcing layer is implemented by substituting a potassium (K) component for a sodium (Na) component existing on a surface of the glass substrate.
5. The touch screen panel as claimed in claim 4 , wherein the reinforcing layer having the potassium (K) component is removed at the edge having the curved shape.
6. A touch screen panel, comprising:
a glass substrate wherein the glass substrate comprises:
a reinforcing layer on a first side and a second side of the glass substrate; and
a non-reinforced curved edge at an end of the first and second sides by exposing the reinforcing layer;
sensing patterns disposed at the first side of the glass substrate;
an insulating layer disposed to cover the sensing patterns;
an adhesive layer disposed on a side of the insulating layer; and
a ground electrode layer disposed opposing the insulating layer.
7. The touch screen panel as claimed in claim 6 , wherein the ground electrode layer comprises indium tin oxide.
8. The touch screen panel as claimed in claim 6 , wherein the sensing patterns comprise an X sensing pattern and a Y sensing pattern.
9. The touch screen panel as claimed in claim 8 , wherein the insulating layer is a second insulating layer disposed to cover the Y sensing pattern and the touch screen panel further comprises a first insulating layer disposed to cover the X sensing pattern.
10. The touch screen panel as claimed in claim 6 , further comprising a display panel on the ground electrode layer.
11. The touch screen panel as claimed in claim 10 , wherein the side of the insulating layer is towards the first side of the glass substrate.
12. The touch screen panel as claimed in claim 11 , further comprising a buffer film between the adhesive layer and the ground electrode layer.
13. The touch screen panel as claimed in claim 12 , wherein the buffer film comprises polyethylene terephthalate.
