A single-chip device for driving a panel, the panel including a plurality of display pixels, a plurality of touch sensors, and a plurality of fingerprint sensing pixels, the panel further including a plurality of data lines coupled to the display pixels, a plurality of fingerprint sensing lines coupled to the fingerprint sensing pixels, a plurality of touch sensing lines coupled to the touch sensors, and a plurality of selection circuits each coupled to a corresponding set of the plurality of data lines, the single-chip device comprising:
- a main body having a left portion and a right portion with respect to an axis, wherein the main body has a rectangular shape having a first side and a second side parallel to the first side and closer to the panel than the first side;
- a first group of pads disposed in the main body and comprising a plurality of first pads for driving the fingerprint sensing pixels, the first group of pads being disposed on both the left portion and the right portion and configured to be coupled to the fingerprint sensing pixels;
- and
- a second group of pads disposed in the main body and comprising a plurality of second pads for driving the display pixels, and a plurality of third pads for controlling the selection circuits, the second group of pads being disposed on both the left portion and the right portion and configured to be coupled to the panel, wherein the third pads are disposed along the first side;
- and
- a third group of pads, disposed in the main body, for driving the data lines or receiving fingerprint sensing signals from the fingerprint sensing lines or for being coupled to the touch sensing lines of the panel and receiving touch signals from the touch sensing lines, wherein the third group of pads are disposed along the second side.
