A capacitive touch panel includes a plurality of x-line channels extending in a first direction, a plurality of y-line channels extending in a second direction, different from the first direction, and processing circuitry configured to apply a first voltage to the x-line channels, apply a second voltage to the y-line channels, the first voltage and the second voltage having opposite phases to each other, and sense a contact on at least one of intersections of the plurality of x-line channels and the plurality of y-line channels.
