Abstract
A capacitive touch panel includes a substrate and a patterned conductive layer formed on the substrate. The patterned conductive layer includes a plurality of first electrode units, a plurality of second electrode units, a plurality of spaced apart first conductive lines, and a plurality of spaced apart second conductive lines. The first electrode units are capacitively coupled to the second electrode units so as to form a plurality of two dimensionally arranged capacitive sensing units. Each of the first electrode units includes a plurality of first electrodes. Each of the first conductive lines is connected to and extends from at least one of the first electrodes of a respective one of the first electrode units. The second conductive lines extend respectively from the second electrode units, and do not cross the first conductive lines.
