Abstract

Disclosed herein is a touch panel. The touch panel 100 according to a preferred embodiment of the present invention is configured to include a transparent substrate 105 that is partitioned into an active region A and a bezel region B disposed at an edge of the active region A, an electrode pattern 110 formed in the active region A, an electrode wiring 120 formed in the bezel region B so as to be connected with the electrode pattern 110, and a display 130 outputting specific light to the bezel region B.

Claims

1. A touch panel, comprising:

a transparent substrate partitioned into an active region and a bezel region disposed in an edge of the active region;

an electrode pattern formed in the active region;

an electrode wiring formed in the bezel region so as to be connected with the electrode pattern; and

a display outputting specific light to the bezel region.

2. The touch panel as set forth in claim 1, wherein colors of the specific light output by the display are #000000, #828282, #8c8c8c, #969696, #a0a0a0, #aaaaaa, #b4b4b4, #bebebe, #c8c8c8, #d2d2d2, #dcdcdc, #282828, #323232, #3c3c3c, #464646, #505050, #5a5a5a, #646464, #6e6e6e, #787878, #FFFFFF, #00BFFF, #FFC0CB, or #FF1493 based on a hex triplet value of color name charts.

3. The touch panel as set forth in claim 1, wherein the display outputs the specific light to only the bezel regions disposed at both sides of an edge of a long side of the transparent substrate.

4. The touch panel as set forth in claim 1, further comprising:

a window disposed in an opposite direction of the display based on the transparent substrate.

5. The touch panel as set forth in claim 4, wherein the window is provided with a printing part in regions corresponding to the bezel regions disposed at both sides of a short edge of the transparent substrate.

6. The touch panel as set forth in claim 4, wherein the transparent substrate and the window are bonded by a first adhesive layer.

7. The touch panel as set forth in claim 1, wherein the transparent substrate and the display are bonded by a second adhesive layer.

8. The touch panel as set forth in claim 1, wherein the electrode pattern and the electrode wiring are integrally formed.

9. The touch panel as set forth in claim 1, wherein the electrode pattern includes:

a first electrode pattern formed on one surface of the transparent substrate; and

a second electrode pattern formed on the other surface of the transparent substrate.

10. The touch panel as set forth in claim 9, wherein the electrode wiring includes:

a first electrode wiring disposed on one surface of the transparent substrate so as to be connected with the first electrode pattern; and

a second electrode wiring disposed on the other surface of the transparent substrate so as to be connected with the second electrode pattern; and

11. The touch panel as set forth in claim 1, wherein the electrode pattern is formed of copper (Cu), aluminum (Al), gold (Au), silver (Ag), titanium (Ti), palladium (Pd), and chromium (Cr), or a combination thereof.

12. The touch panel as set forth in claim 1, wherein the electrode pattern is formed of metal silver formed by exposing/developing a silver salt emulsion layer.

13. The touch panel as set forth in claim 1, wherein the electrode pattern is black-oxide treated.

14. The touch panel as set forth in claim 1, wherein the electrode wiring is black-oxide treated.
