Abstract

A touch panel capable of decreasing response time includes a first substrate, a second substrate, and a spacer. The first substrate has a plurality of first conductive stripes formed on a lower surface of the first substrate along a first direction. The second substrate is disposed below the first substrate. The second substrate has a plurality of second conductive stripes formed on an upper surface of the second substrate along a second direction. The spacer is arranged between the first substrate and the second substrate for forming a gap between the first substrate and the second substrate.

Claims

1. A capacitive touch panel capable of decreasing response time and reducing interference, the capacitive touch panel comprising:

a first substrate having a plurality of first conductive stripes formed on a lower surface of the first substrate along a first direction;

a second substrate disposed below the first substrate, having a plurality of second conductive stripes formed on a upper surface of the second substrate along a second direction; and

a spacer arranged between the first substrate and the second substrate for forming a gap between the first substrate and the second substrate.

2. The capacitive touch panel of claim 1, wherein the first and second conductive stripes are transparent conductive stripes made of indium tin oxide, transparent conductive polymer film, or transparent metalloid film.

3. The capacitive touch panel of claim 1, wherein the spacer is arranged in edges of the capacitive touch panel.

4. The capacitive touch panel of claim 3 further comprising a plurality of spacing dots arranged in an inner side of the spacer, the spacing dots can be in any shape.

5. The capacitive touch panel of claim 3, wherein the spacer encloses the capacitive touch panel along the edges of the capacitive touch panel.

6. The capacitive touch panel of claim 1, wherein the first substrate is a glass substrate.
