Abstract
A touch panel includes a cover plate, a first adhesive component, and a second adhesive component. The first adhesive component which is adhered underneath the cover plate, includes a plurality of first pattered sensing lines. The second adhesive component which is adhered underneath the first adhesive component, includes a plurality of second pattered sensing lines. The first pattered sensing lines and second pattered sensing lines are electrically insulated from each other.
Claims20
A method of fabricating a touch panel, comprising:
- providing a cover plate;
- adhering a first adhesive component underneath the cover plate, comprising:
