Abstract

Disclosed herein are a capacitive touch screen and a method for manufacturing the same. The capacitive touch screen includes: a base member on which a plurality of electrode patterns are formed; conductive adhesive members formed at ends of the electrode patterns; a window disposed over the base member and having a plurality of electrode wirings formed in an outer region thereof, the plurality of electrode wirings being opposite to the electrode patterns; and auxiliary electrodes formed at one of the ends of the electrode wirings to conduct the electrode patterns with the electrode wirings by the conductive adhesive members.

Claims (22)

1. A capacitive touch screen, comprising:

a base member on which a plurality of electrode patterns are formed;

conductive adhesive members formed at ends of the electrode patterns;

a window disposed over the base member and having a plurality of electrode wirings formed in an outer region thereof, the plurality of electrode wirings being opposite to the electrode patterns; and

auxiliary electrodes formed at one of the ends of the electrode wirings to conduct the electrode patterns with the electrode wirings by the conductive adhesive members.

2. The capacitive touch screen as set forth in claim 1 , wherein an area of the auxiliary electrode corresponds to that of the conductive adhesive member.

3. The capacitive touch screen as set forth in claim 1 , further comprising a covering film formed on an upper outer region of the window to cover the electrode wirings.

4. The capacitive touch screen as set forth in claim 1 , wherein the electrode pattern is made of a conductive polymer.

5. The capacitive touch screen as set forth in claim 1 , wherein the electrode pattern includes a first electrode pattern and a second electrode pattern intersected with each other,

the first electrode pattern including first connectors connecting a plurality of first sensors to the adjacent first sensors,

the second electrode pattern including second connectors connecting a plurality of second sensors formed on the same plane as the first sensors to the adjacent second sensors,

the second connectors formed over the first connectors to intersect therewith.

6. The capacitive touch screen as set forth in claim 5 , further comprising an insulating pattern disposed between the first connector and the second connector to prevent the first connector from contacting the second connector.

7. The capacitive touch screen as set forth in claim 1 , further comprising a double-sided adhesive member formed in an upper outer region of the base member to bond the window to the base member.

8. A method for manufacturing a capacitive touch screen, comprising:

forming a plurality of electrode patterns on one surface of a base member and forming conductive adhesive member at ends of the electrode patterns;

forming a plurality of electrode wirings on one surface of a window and forming auxiliary electrodes at one of the ends of the electrode wirings;

coupling the base member to the window so that the auxiliary electrodes are adhered to the conductive adhesive members to conduct the electrode wirings with the electrode patterns.

9. The method for manufacturing a capacitive touch screen as set forth in claim 8 , wherein the electrode wiring is made of a metal and is formed by a sputtering method.

10. The method for manufacturing a capacitive touch screen as set forth in claim 8 , wherein the electrode pattern is made of a conductive polymer.

11. The method for manufacturing a capacitive touch screen as set forth in claim 8 , further comprising forming a covering film covering the electrode wirings in an upper outer region of the window.

12. The method for manufacturing a capacitive touch screen as set forth in claim 8 , further comprising, prior to the coupling the base member to the window, forming a double-sided adhesive member bonding the base member to the window in an upper outer region of the base member or a lower outer region of the window.
