1. A sensor system comprising:
a first sensor electrode group and a first integrated circuit connected to the first sensor electrode group; and
a second sensor electrode group and a second integrated circuit different from the first integrated circuit and connected to the second sensor electrode group,
wherein the first sensor electrode group is disposed under a first panel surface and the second sensor electrode group is disposed under a second panel surface different from the first panel surface, and the first panel surface is rotatable with respect to the second panel surface,
wherein, when the first integrated circuit is paired with a stylus, the first integrated circuit shares pairing information regarding the pairing, with the second integrated circuit,
wherein a reach of a first uplink signal transmitted from the first integrated circuit via the first sensor electrode group overlaps with a reach of a second uplink signal transmitted from the second integrated circuit via the second sensor electrode, responsive to the first panel surface, from which the first uplink signal is transmitted, being rotated to assume an angle less than 180 degrees relative to the second panel surface, from which the second uplink signal is transmitted, and
wherein the first and second integrated circuits are controlled such that the first uplink signal is transmitted from the first panel surface at a first timing and the second uplink signal is transmitted from the second panel surface at a second timing which alternates with the first timing.
