Abstract

A touch panel includes: multiple first electrodes parallel to a first axis; multiple second electrodes parallel to a second axis; and multiple third electrodes parallel to the second axis. Each of the first electrodes is arranged to be spanned on the touch panel and intersects with the multiple second electrodes or the multiple third electrodes to form multiple intersection areas.
