Abstract

An improved touch panel is disclosed. The touch panel according to the invention comprises a transparent substrate, a first transparent insulative sheet joined to the transparent substrate to form a first gap therebetween, a second transparent insulative sheet joined to the first transparent insulative sheet to form a second gap therebetween, a first transparent conductive film formed over the transparent insulative sheet within the second gap, and a second transparent conductive film formed over the second transparent insulative sheet within the second gap. Furthermore, a first anti-Newton ring film can be formed over the first transparent insulative sheet within the first gap, and a second anti-Newton ring film can be formed between the second transparent conductive film and the second transparent insulative sheet.

Claims

1. A touch panel, comprising:

a transparent substrate;

a first transparent insulative sheet joined to said transparent substrate to form a first gap therebetween;

a second transparent insulative sheet joined to said first transparent insulative sheet to form a second gap therebetween;

a first transparent conductive film formed over said first transparent insulative sheet within said second gap; and

a second transparent conductive film formed over said second transparent insulative sheet within said second gap.

2. The touch panel as claimed in claim 1, further comprising a first anti-Newton ring film formed over said first transparent insulative sheet within said first gap.

3. The touch panel as claimed in claim 1, further comprising a second anti-Newton ring film formed between said second transparent conductive film and said second transparent insulative sheet.

4. The touch panel as claimed in claim 1, wherein said transparent substrate is selectively from a group consisting of plastic, acrylic, glass and PC materials.

5. The touch panel as claimed in claim 1, wherein said first transparent insulative sheet is selectively from a group consisting of PET, PC, ARTON, and ZEON materials.

6. The touch panel as claimed in claim 1, wherein said second transparent insulative sheet is selectively from a group consisting of PET, PC, ARTON, and ZEON materials.

7. The touch panel as claimed in claim 1, wherein said first transparent conductive film and said second transparent conductive film are made of indium tin oxide (ITO) films.

8. The touch panel as claimed in claim 1, further comprising a plurality of spacers formed on said first transparent conductive film.

9. A touch panel, comprising:

a transparent substrate;

a first transparent insulative sheet joined to said transparent substrate to form a first gap therebetween;

a second transparent insulative sheet joined to said first transparent insulative sheet to form a second gap therebetween;

a first transparent conductive film formed over said first transparent insulative sheet within said second gap;

a second transparent conductive film formed over said second transparent insulative sheet within said second gap;

a first anti-Newton ring film formed over said first transparent insulative sheet within said first gap; and

a second anti-Newton ring film formed between said second transparent conductive film and said second transparent insulative sheet.

10. The touch panel as claimed in claim 9, wherein said transparent substrate is selectively from a group consisting of plastic, acrylic, glass and PC materials.

11. The touch panel as claimed in claim 9, wherein said first transparent insulative sheet is selectively from a group consisting of PET, PC, ARTON, and ZEON materials.

12. The touch panel as claimed in claim 9, wherein said second transparent insulative sheet is selectively from a group consisting of PET, PC, ARTON, and ZEON materials.

13. The touch panel as claimed in claim 9, wherein said first transparent conductive film and said second transparent conductive film are made of indium tin oxide (ITO) films.

14. The touch panel as claimed in claim 9, further comprising a plurality of spacers formed on said first transparent conductive film.
