Abstract
A capacitive sensing device includes: a substrate; a touch sensing electrode group, disposed above the substrate; a fingerprint sensing electrode group, disposed above the substrate; and a capacitive sensing integrated circuit, electrically connected to the touch sensing electrode group and the fingerprint sensing electrode group, sensing a capacitance change in the touch sensing electrode group to generate a touch control instruction, and sensing a capacitance change in the fingerprint sensing electrode group to generate a fingerprint pattern.
