Claim 0:
1. A touch panel comprising:
a first sensor module; and
a second sensor module overlapping the first sensor module;
the first sensor module comprising:
a cover member;
a first sensor array overlapping the cover member, the first sensor array including a first detection area equipped with a plurality of first sensor electrodes, the first sensor array being a non-contact type;
a control unit receiving a first detection signal output from the first sensor array and generating coordinate information based on the first detection signal;
a drive unit receiving the coordinate information from the control unit and outputting a drive signal based on the coordinate information; and
a drive electrode array being driven based on the drive signal and including a plurality of drive electrodes, the drive signal being applied to at least one of the drive electrodes, the at least one corresponding to a coordinate included in the coordinate information,

the second sensor module comprising:
a second sensor array including a second detection area, the second detection area being arranged to overlap the first detection area via the drive electrode array, the second detection area being equipped with a plurality of second sensor electrodes, the second sensor array identifying a position corresponding to the coordinate information in the second detection area based on the drive signal supplied to the drive electrode array,

wherein the plurality of drive electrodes of the drive electrode array and the plurality of second sensor electrodes face each other one-to-one.
