    Abstract: A sensing panel includes a sensing base layer, a first group of fingerprint sensing pixels disposed on a first region of the sensing base layer and connected to a plurality of fingerprint scan lines and a plurality of first fingerprint receiving lines, and a first pen sensing pixel disposed on a second region of the sensing base layer and connected to a pen scan line, a first pen transmission line, and a first pen receiving line. The first pen sensing pixel includes a first sensing coil surrounding the first region of the sensing base layer on which the first group of fingerprint sensing pixels are disposed. A portion of the first sensing coil is adjacent to a first fingerprint sensing pixel of the first group of fingerprint sensing pixels.
