Abstract

Disclosed herein is a touch screen having an antenna, including: a first substrate that includes a first electrode pattern formed in an active region and a first electrode wiring formed in an inactive region disposed outside the active region and connected to the first electrode pattern; a second substrate that includes a second electrode pattern opposite to the first electrode pattern and a second electrode wiring connected to the second electrode pattern; a spacer that is formed between the first substrate and the second substrate to space the first electrode pattern from the second electrode pattern; and an antenna pattern that is formed in the inactive region.

Claims

1. A touch screen having an antenna pattern, comprising:

a first substrate that includes a first electrode pattern formed in an active region and a first electrode wiring formed in an inactive region disposed outside the active region and connected to the first electrode pattern;

a second substrate that includes a second electrode pattern opposite to the first electrode pattern and a second electrode wiring connected to the second electrode pattern;

a spacer that is formed between the first substrate and the second substrate to space the first electrode pattern from the second electrode pattern; and

an antenna pattern that is formed in the inactive region.

2. The touch screen having an antenna pattern as set forth in claim 1, wherein the antenna pattern is formed in the inactive region of the first substrate and is formed outside the first electrode wiring.

3. The touch screen having an antenna pattern as set forth in claim 1, wherein the antenna pattern is formed in the inactive region of the second substrate and is formed outside the second electrode wiring.

4. The touch screen having an antenna pattern as set forth in claim 1, wherein the antenna pattern is made of the same material as that of the first electrode pattern or the first electrode wiling.

5. The touch screen having an antenna pattern as set forth in claim 4, wherein the antenna pattern is made of a transparent conductive polymer.

6. The touch screen having an antenna pattern as set forth in claim 1, wherein an end of the first electrode wiring, an end of the second electrode wiring, and an end of the antenna pattern are collected at a connection unit formed at one side of the touch screen.

7. The touch screen having an antenna pattern as set forth in claim 1, wherein the touch screen is a resistive touch screen or a capacitive touch screen.
